Interacting with VB6 client using hidden control in embedded web browser control - vb6

I'm having difficulty trapping a programmatically triggered click event on a hidden button control from a ASP.NET MVC 4 web app inside a VB6 thick client (which is using a web browser control). I'm able to trap the click event itself using the following:
Private WithEvents WebDoc As HTMLDocument
Private Function WebDoc_onclick() As Boolean
Select Case WebDoc.activeElement.iD
Case "A"
Do something
Case "C"
Do something else
End Select
WebDoc_onclick = True
End Function
And this works just fine if the control is visible. But if the control is invisible:
<div class="HideBtnDiv">
<input id="C" name="NoItems" type="button" class="BtnDiv" style="display:none"/>
</div>
and I try to trigger a programmatic click via one of the following:
$("#C").('click');
$("#C").trigger('click');
$("#C").triggerhandler("click");
$("#C").focus();
$("#C").trigger('click');
I'm getting an empty string for the "id" attribute and as a result I can't distinguish which button was clicked. This button serves no purpose other than to indicate to the VB6 app that a certain criteria has been met and that's the reason why I need it to be hidden. Does anyone have any idea why the id is getting stripped? Or is there any other way to communicate back to the client?
I've also tried filtering by element style using
Select Case WebDoc.activeElement.Style
Case "display:none"
Do something else
End Select
but it came back as "[Object]" so no luck there either. Please let me know if there is a way around this.
Thanks,
Lijin

You seem to have tried several ways of dynamically triggering the click event, but did you try the most obvious way:
$("#C").click();
???
But here is what I would do:
1- Make all of your buttons visible, by removing "display:none" from their style
2- Wrap the buttons you want to hide in a new DIV
3- Set "display:none" style in the newly created DIV
4- You can then trigger the .click() event of any button even if not visible by calling $(id).click();

Thanks, Ahmad. Actually I meant .click() not .('click'). Sorry about that.
Anyway, I tried your suggestion and made the button visible and set the style of the wrapping div to display:none but the id attribute was still coming through as an empty string.
However, I did figure out another way to get this to work. If I keep the wrapping div and button as visible and then focus and click when the condition is met and then do a hide(), my problem is resolved!
$("#C").focus();
$("#C").trigger('click');
$("#C").hide();
The button doesn't get displayed and VB6 still passes the id on the click event. The weird thing is it requires the focus() call to still be made. Without it, I'm back to square one. Not sure if this is a bug.

Kendo UI Angular 2+ Sortable drag handle

I am using the sortable component from the Kendo UI Angular 2 library to create a list of custom components which the user can drag and drop to rearrange as they need. By default, the sortable's items can be dragged by clicking anywhere within the item. My question is: can we specify a handle like we would in the classic Kendo UI? I want the user to drag the item only when using the header of the item, not the body.
I could not find anything in the documentation and I was hoping that if anyone had done it they can point me in the right direction.
Thanks.
Without access to the TypeScript source code (only have access to the transpiled JavaScript), it's hard to tell, but based on my quick examination the answer is no. It doesn't support options like the Kendo UI JavaScript version does where you can specify a handle selector.
If you have a handle element, according to the docs, you're supposed to add the draggable="true" attribute to your element in the Sortable's template.
See http://www.telerik.com/kendo-angular-ui/components/sortable/#toc-known-limitations
<kendo-sortable [data]="items">
<ng-template let-item="item">
<button draggable="true">
{{item}}
</button>
</ng-template>
</kendo-sortable>
My experience with this Kendo Angular component is it's not that great. I have my own open issue with it. It doesn't seem to work well outside a narrow scope.
For now, at least in my project, we'll be using Dragula. There is an Angular2+ wrapper for it available. It does support handles and such in its options.
https://github.com/valor-software/ng2-dragula
I know it has been years since this original question was asked, but as of this writing, Kendo still does not support a "handle" mechanism natively. There is, however, a way to implement the "handle" feature, which I will write here in hopes that someone in the future may find this helpful. Note I don't believe this is the right solution, because I believe Kendo's API should have this feature.
Using a Mouse
Prevent Drag Start
When we start to drag on the widget, we only want dragging to occur if our mouse is over a valid handle.
Define a flag in your component's code.
/** whether we should allow dragging **/
allowDrag: boolean = false;
Listen for dragStart on the kendo-sortable element
<kendo-sortable (dragStart)="onDragStart($event)">
Stop the default dragStart event when the flag is true
/** handles the starting of dragging */
onDragStart(e: DragStartEvent): void {
if (!this.allowDrag) {
e.preventDefault();
return;
}
}
Toggle on mouseover and mouseleave
When your mouse is over the handle element, enable the flag. When your mouse leaves the element, disable the flag.
<div (mouseover)="allowDrag = true" (mouseleave)="allowDrag = false" class="drag-handle"></div>
Incorporating Touchscreen Users
The philosophy of the above approach relies on only listening for the mouseover and mouseleave events on the handle, and ignoring everything else. For mobile - it's a bit trickier, because there isn't a mouse-position that specifically defines whether a user in position to make a drag. So, we have to add a listener to handle elements, as well as to all other non-handle elements we don't want dragging on. This approach could have been employed for mouse clicks as well, though I believe only attaching to the handle elements is the better approach.
Note: I haven't fully tested this approach yet, and it may not be suitable in all conditions, and may not work as expected for all users.
Add the touchstart Event
In your view, listen for touching the handle
<div (touchstart)="allowDrag = true" (mouseover)="allowDrag = true"
(mouseleave)="allowDrag = false" class="drag-handle"></div>
Also including touching all things that aren't handles
<div (touchstart)="allowDrag = false">
My non-draggable thing
</div>

Coded UI Test - Set UI property not returning (hanging indefinitely)

I am getting crazy with a problem that I found when executing a Visual Studio Coded UI Test.
The scenario is as follows.
I recorded a Coded UI Tests that do the following steps in a Web Application (Microsoft Dynamics CRM 2011):
Login into an application
Navigate into a page
On the page set the selected value of a html combobox
The test is able to do all those steps without a problem, even selecting the value in the combobox.
The web application have a piece of Javascript that is executed when the selected item changes.
if one of the values is selected then an alert message is presented to the user and the application will set the selected item to a default one!
The javascript code look like this:
switch (Xrm.Page.getAttribute("status").getValue()) {
case 3: //Authorised
alert("Please use the method XPTO to update the record status to Authorised!");
Xrm.Page.getAttribute("status").setValue(1);
Xrm.Page.getControl("tatus").setFocus(true);
return false;
The UI Test method that is performing the change in the combobox is as follows:
/// <summary>
/// Select a value in the Status dropdown box
/// </summary>
public void SelectStatus()
{
#region Variable Declarations
HtmlComboBox uIStatusComboBox = this.UIHttpsappWindow200.UIModuleUITEDocument5.UIWorkplaceDashboardsFrame.UIModuleUITEDocument.UIStatusComboBox;
// Select 'Authorised' in 'Status' combo box
uIStatusComboBox.SelectedItem = this.SelectStatus_SPParams.UIStatusComboBoxSelectedItem;
}
The test method is able to change the value in the combobox, and an alert message is displayed to the user. However this part of the code uIStatusComboBox.SelectedItem = this.SelectStatus_SPParams.UIStatusComboBoxSelectedItem;
never returns and the test just hangs there until it timeouts!
I have no ideia how to work arround this issue! I was thinking that maybe the problem could be in the fact that we have javascript code that is executed after the alert is displayed to the user. I changed the JS so that the alert message is the last thing to be displayed but it also didn´t help!
I also noticed that if I click Ok on the alert message the test Pass!
If I select other value that dont trigger any JS the test also Pass!
Does anyone have any idea about this issue?
Edit 1:
I noticed another thing, I can use the BrowserWindow object to send a JS script to the browser. If I try to create an alert message the call also gets blocked until I click on the Ok button, on the alert!
BrowserWindow bw = BrowserWindow.Locate("My window");
bw.ExecuteScript("alert('This is just a simple alert.');");
The ExecuteScript statement also gets blocked until I click on the OK button!
This seems very very strange!
I believe I have found a workaround.
I was googling to find anything that could help me with this issue and I end up finding this question on StackOverflow Coded ui test - Select an item from a combobox without using mouse coordinates
I try to select the same item in the Dropdown without using the "SelectedItem" property of the HtmlComboBox element.
I try to use the keyboard to select the element in the dropdown box, first I click on the Dropdown and then I use the Down key and Enter key to select the element that I want:
public void SelectStatus_SP(string SelectedItem)
{
#region Variable Declarations
HtmlComboBox uIStatusComboBox = this.UIHttpsappWindow200.UIpopupUITEDocument5.UIWorkplaceDashboardsFrame.UIpopupUITEDocument.UIStatusComboBox;
#endregion
Mouse.Click(uIStatusComboBox);
Keyboard.SendKeys(uIStatusComboBox, "{Down}{Down}{Enter}", ModifierKeys.None);
}
In my case the element that I want to select is the 3rd one, so I go down 2 times and then hit enter on the element I want to select.
This workaround is not so good because if the element changes position I will select the worng one! But this was the only way I got for the test not to be stock in that part!
I wonder if anyone had a similar issue. Because to me this seems like a bug in the Coded UI Test engine, It doesn´t make any scence for the test to be stocked while the alert is not closed!

How to stop Telerik RadWindow from always reloading on the next PostBack 2

Greetings to you dear colleagues!
Prompt.
I have here a situation - there is a component RadWindows RadButton button on it by pressing a button in the RadGrid RadWindows component is set to Visible = true; But after PostBack and shape RadWindows disappears. But going into the RadWindows everything remains as it was changed to reboot.
Question: How to prevent reload the page.
Who does not know what are the components of Rad Teleric.
The source code can throw if it helps.
Thank you, Regards!
Set DestroyOnClose="true" to prevent the window from reopening after close or postback. It sounds like you may be setting the Visible property to true using server-side code. This is bad practice which leads to issues like you describe. RadWindows should be opened via the client-side methods.
On the server side use this code to open a window from the client side using the RadWindow.Show client-side method while having DestoryOnClose set to true. You can customize the script string should you want to use the RadWindow.Open() method to pass a url to the window.
private void ShowWindow()
{
string script = "function f(){$find(\"" + YourRadWindow.ClientID + "\").show(); Sys.Application.remove_load(f);}Sys.Application.add_load(f);";
ScriptManager.RegisterStartupScript(Page, Page.GetType(), "key", script, true);
}
Consider opening it with JavaScript, this will let you stop using these unnecessary postbacks: http://www.telerik.com/help/aspnet-ajax/window-programming-opening.html.
Use OnClientClicking of the RadButton: http://blogs.telerik.com/aspnet-ajax/posts/12-08-10/migrating-onclientclick-handlers-from-asp-button-to-telerik-s-asp-net-ajax-button.aspx.
You can also use AJAX to prevent full postbacks that will dispose (and thus, hide) the RadWindow: http://www.telerik.com/help/aspnet-ajax/radwindow-ajaxifying.html.
Read this sticky to see how to open it from the server if you need to. If you set VisibleOnPageLoad to true it will re-show after postbacks, so you will only need to take care of setting the property back to false when you need to: http://www.telerik.com/community/forums/aspnet-ajax/window/opening-radwindow-from-the-server.aspx.

How to call the same function that the ToolBar editbutton does

So I have created a context box upon right click that has Add/Edit/Delete Rows. I also have a bunch of code launched before the Dialog is shown. My problem is that when I use the context menu it doesn't go through some of the code. I have tried to call on the functions directly but it doesn't format correctly.
I am mainly concerned with the edit button, here is the code I am using to bring up the edit Dialog
function editRow() {
var grid = jQuery("#<%= Jqgrid1.ClientID %>");
var rowKey = grid.getGridParam("selrow");
if (rowKey) {
// I have tried calling functions here and it still doesn't work
grid.editGridRow(rowKey, grid.editDialogOptions);
}
else {
alert("No rows are selected");
}
}
So if I use this to display the editform it isn't formatted correctly nor does it go through the functions all correctly.
I am using the ASP Webforms version of Jqgrid so I call the function by doing this
<cc1:JQGrid1 ID="Jqgrid1
//other attributes
ClientSideEvents-BeforeEditDialogShown="ChangeMonitor"
//Rest of code />
So this works just fine, and I'm trying to get the Edit button on the context menu to display correctly.
My thought was to use Jquery to trigger a click on the actual Edit button once someone used the context menu. I couldn't find an ID that would work however.
Is there an easy way to connect my context menu Edit button, with the actual Edit button in the toolbar?
Well I found a solution to my problem.
The id field of the button was edit_ct100_cpMainContent_Jqgrid1_top so I just triggered a click with this code.
$("td[id^=edit][id$=top]").trigger("click")
For some reason when I used the _ct100_cpMainContent_Jqgrid1 it wasn't working, but now it does. Hope this helps someone.

My Asp.Net Form data is not being submitted properly by Selenium 2 (Webdriver)

So I have written a test which populates a form, saves (in the admin tool), and then publishes.
However, my form is being lost between the save click and the publish click. I would show what the form looks like in HTML, but its pretty huge (like 20-30 fields)
In psuedo code, filling out the form looks like this:
1) Fill in form using dropdowns
2) Hit the save button - saves all form data
3) Hit the publish button
When I pause the script to see what is happening within selenium, I see the form properly being populated. I then see the Save button properly being clicked. When I pause the screen before hitting publish, I see that the content I have saved after clicking the save button was lost or is in the wrong fields.
When I do this manually, it works correctly. I know selenium submits forms differently than the standard user, however, is there anything I can do on my end to make sure that form is being submitted properly?
What does the Save button actually do? Is it Javascript, or a simple ` button?
Are you using the C# interface to Selenium webdriver? You probably have code that looks something like this:
FillInForm();
selenium.click(By.CssSelector("input[value='Save']"));
selenium.click(By.CssSelector("input[value='Publish']"));
Have you tried inserting, between save and publish, lines like the following:
// further up: By saveButton = ...
// By formField = ...
selenium.click(saveButton);
var formField = selenium.FindElement(formField);
Assert.That(formField.GetAttribute("value")
.contains("The text you typed into the form")
);
The point here being to check that save really is doing what it says on the tin. Generally, when you ask the WebDriver to "click" on a button, it does do exactly (more or less) what the user does. Alternatively, you can inject some javascript to force the form to submit - but then you're explicitly not testing what the user actually does (but you might find it's closer to what you experience).
