I am using dijit ComboBox 1.9.1 on my web page. After keypress I am waiting 0.6s and then send the value to server and get the list of the answers which I fill to ComboBox datastore and open the DropDown with fetched values.
I realize strange thing in IE9: if first DropDown is short it is ok - without scrollbars, than if it longer the scrollbars are visible. After than, if next DropDown is e.g. only one item, scrollbars are visible again which makes the result item completely unreadable. FF is ok with this.
Does somebody know how to solve this or any possible workaround? Resetting the CombBox widget doesn't help.

I need the ability for a user to press and set an ListView item's checkbox independently of clicking on the item. If they press on the checkbox I will add/remove the checkmark and take some action. If they press on the item text I can take another action.
I can do this with a ListBox no problem with built in functionality. I can't figure out how to do it with a ListView. How is it done?
I can put the following code in the ListView1ItemClickEx to know when the user is clicking on the image. Maybe I can just change the image to a checkmark?
if (ItemObject->Name == "I") {
ShowMessage("Item Image clicked");
}
But I don't know how to change that particular items image (e.g. I could just toggle between a checkmark image and an unchecked image) at runtime.
The picture below is for clarity. Clicking anywhere in the red box will change the items checkbox. For the ListBox clicking anywhere in the blue box will fire the OnClick event and not change the checkbox. I want that same behavior in the ListView.
Ok, Remy answered this related question and it helped me solve this issue. Now I can make the ListView have a checkbox that functions like that of the ListBox. I do it by toggling the item image whenever the user presses (or clicks on) the image area of an item.
When the user clicks an items image I trap it (per Remy's code in the ListView1ItemClickEx event) and toggle it from 0->1 or 1->0 in a vector at reference ItemIndex (e.g. myVector[ItemIndex] = 0) and then I completely rebuild the ListView (clear it and build from scratch).
I thought I'd have to remember where in the list I had scrolled down to and after refreshing the ListView I'd have to scroll to that point in code - but, that isn't the case. I don't know why but after the refresh I'm still at the point in the list where I clicked an item image. It makes it work and feel exactly like a check box.
It works great in iOS, Android, and Windows.
p.s. I forgot to mention that you need to treat any Header's like they are items in your vector that keeps up with each items' image (0 or 1). Otherwise adding headers gets you out of sync and clicking an item's image will toggle some other item's image.
I have some pages where I have a kendo ui grid (wired up to full CRUD services), but use a separate Kendo UI Toolbar control (as opposed to the toolbar configuration in the grid itself). I have a number of different buttons/menus on the toolbar, but am seeing a strange behavior when calling saveChanges() on the grid. If a cell is being edited when the save button is clicked, the grid is saved, but the edited value is lost (it reverts back to where it was). The following details what I see in different situations:
When using a save button configured in the grid (command: "save"), any changes in a cell being edited are committed with the save.
When using a plain html button that calls the saveChanges() method of the grid, any changes in a cell being edited are committed with the save.
When using a save button configured in a toolbar control, the changes in a cell being edited are LOST when saveChanges() is called.
The following jsbin shows the behavior of all three:
http://jsbin.com/jazobexatu/2/edit?html,js,output
I have tried calling the save from the toolbar button a number of different ways (even trying to trigger the click event of the external button), but nothing seems to correct the behavior. I also tried calling closeCell() on the grid (to try to force the value back into the data, but that doesn't work either). I haven't been able to debug the javascript enough to figure out what is different. I'm hoping someone with a deeper understanding of these controls can help me out.
For some reason, the mouse down event on the toolbar button doesn't cause a blur on the editor.
You can try it yourself by clicking in the cell to edit it, then click and hold the mouse button down on the "normal" button. The editor closes on mouse down, causing a blur of the editor, and persists the change.
If you do the same thing, click and hold mouse down, on the toolbar button, the editor stays open.
I've been poking through the source, but haven't figured out exactly why this happens. My best guess would be that the mousedown handler on the toolbar prevents the event from bubbling or running its default action and the editor doesn't blur.
Additional detail: On mousedown on the grid header button and the normal button, the focused element changes (which is what causes the editor blur). But on mousedown of the toolbar button, the editor input element still has the focus.
Shifting the focus on mousedown of the toolbar might be a workaround.
Sort of a weird hack, but this works in Chrome (any should in any browser that supports activeElement
click: function (e) {
$(document.activeElement).blur();
$("#grid").data("kendoGrid").saveChanges();
}
I've been struggling for weeks trying to crack this nut so I'm not sure if it's impossible, or if it's my lack of coding chops... or both. I'm not a programmer and I'm a newbie to Dojo Toolkit.
I have a site using the BorderContainer layout. I'm trying to create an effect where I can use a button to open and close a dropdown type box that will contain controls. I need this dropdown to be hidden on page load, and then open when you click the button.
My problem is that when I open the dropdown, it pushes the content pane below it off the bottom of the browser window. I need the lower ContentPane to stay fit within the remaining space of the browser window when the dropdown opens. Additionally, I want the dropdown to sit outside of the scrollable container for the content below it, which is why I have it set up to sit outside a nested BorderContainer below it.
I've created a simplified version of the code to demonstrate my challenge (see link below). If you load the page you can see the center ContentPane scrolls the content. But, if you then click on the button, a dropdown div expands above the content. Then when you scroll, you'll notice that you can't see the full pane because it's in no-man's-land below the bottom of the browser window. I assume that because the div is set to display:none on load, it's size is not accounted for on page load. Then, when you open it by pressing the button, it's size is additive and the pane below doesn't know how to resize or account for the new element.
I've tried using the visibility attribute, but that leaves a gap for the div when it's still closed. I've tinkered with some code that controls the height that shows promise, but each of my dropdown boxes will be different sizes so I'd prefer that the height be set to "auto" rather than a specified pixel size.
Does anyone have any idea how I can accomplish this so that the lower pane will fit in the space without pushing off the screen?
Here's a sample of the page:
http://equium.com/scaffold.html
(I had some problems trying to insert the full HTML page here as a code sample so if that's a preferable way to handle it, and someone can let me know the best way to embed all of that code, I'd appreciate it.)
Thanks is advance, I'd really apprecaite anyone's feedback.
You might want to take a look at dojox.layout.ExpandoPane (though be warned I think it has only worked properly for top and left regions for a while).
Also, I'd suggest simplifying/altering your layout a bit. See example here:
http://jsfiddle.net/taFzv/
(It'd probably need some tweaking to get exactly what you want.)
The real issue you're having is probably that the BorderContainer has no idea that parts of the view resized. ExpandoPane takes care of that by telling the BorderContainer to re-layout after its animation completes.
It works under IE8.0. When dropdown box open, just keep pressing mouse from page and drag to bottom, you could see the content was pushed to out of page. It looks the browser could not detect it and could not add it to "scroll bar" account.
I would suggest taking out all BorderContainers except your top level one, the one with mainPage as the id.
Place your {stuff here} div into the mainPage BorderContainer, after the ContentPane with the Close/Open button. Make sure you make it dojotype dijit.layout.ContentPane, set up layoutpriority, and set region to top. Set the height to 0/x when clicking the Open/Close button, instead of setting display.
Try your page again. If that doesn't fix it, you probably need, a call to layout, resize, or both to indicate to the BorderContainer that it needs to evaluate all its children and size the "center" pane properly. Something like dijit.byId("mainPage").layout(); Do this any time someone presses the Close/Open button, after you have changed the height of any BorderContainer children.
Maybe the dijit.form.DropDownButton would fit your needs. When click the button a tooltip is displayed that can be filled with any content you want. Just as you specified, the dropdown tooltip is only displayed when you click the button, and it doesn't mess with the underlying layout at all. The tooltip sits "on top" of the page.
i want to swipe webbrowser Control which is on pivot item ,each pivot item
has a web control .i want to swipe with web browser control .
but i don't have any idea.but swiping is necessary in my project .is there any method to doing this if yes then please send me sample code for this ..
This is a bind if you have some different sections of HTML you want to display in a Pivot. If you are targetting WP7 Mango it might be possible for you to convert your HTML to RTF and then use a RichTextBox instead of a WebBrowser. However if your HTML is fairly complex, this probably isn't going to work for you.
Alternatively you could place your WebBrowser in a pivot item with a transparent Rectangle above it in the Z-order. Make sure that Rectangle swallows any gestures and doesn't pass them through to the WebBrowser control - that way you will be able to swipe left and right on the WebBrowser to get the pivot to move.
Next you can use the GestureService on this transparent rectangle to recognize vertical pans/swipes and taps to take you to a full page view of your WebBrowser content. In this full page view you would have a fully interactive WebBrowser control.
You have an issue with competing gestures. Try setting the WebBrowser control to IsHitTestVisible to false. This will mean that you'll be unable to manipulate or scroll the content of the WebBrowser control though.
shanu: if you still need it, check my recent answer at: WP7 Pivot control and a WebBrowser control
There's a bit of info on how to "hack into" the webbrowser and what to do, to (almost) prevent it from stealing your swipes. If you are insane/masochistic enough to try that approach I described there, then in addition to that eventhandling and other configuration/detection, you will have to drive your pivot manually via relevant pivot.selectedindex++/-- on H-swipes detected with your handlers (or you can separate blocking and observing with gesture listener, that may sometimes result in the code being a bit cleaner). I also think you will have to be careful with the selectedindex near to the page ranges. I dont know how pivot behaves if you order it to go further than you page count, and I dont know either if it will animate correctly, if being on the last page you order it to go "wrap around" and go to page 0 via selectedindex=0. It may get "crazy" and rewind back instead of going forward in a circular fashion.. you will have to experiment with that
Ive never seen this.
I click into my textbox to type in a value and as soon as i release the mouse button focus jumps to the above dropdown list. No javascript on these items.
If i hold the mouse button down i can type in a value to the textbox.
Any idea?
I had my textbox inside the label tag by mistake - this was the reason the focus jumped for me
Someone might be catching the mouseup event.
Event handling differs across browsers which might explain why it happens in all browsers except IE7.
