I would like to add items to a dropdownlist progmatically.
I have an empty drop downlist and depending on a number of factors I then populate it with various action choices.
the Drop Down list is called dlFirstChoice and I would like to add some values to it, can some one give me the basic code to do so, I have tired ILists and Arrays as the Dataprovider but clearly Im doing something wrong.
Please and thank you in advance for any help.
var dropListDb:ArrayList=new ArrayList();
dropListDb.addItem({label: "Equals (List)"});
dropListDb.addItem({label: "Is Between"});
dlFirstChoice.visible = true;
dlFirstChoice.dataProvider=dropListDb;
dlFirstChoice.selectedIndex=0;

I'm using Carousel View by alexrainman for creating custom wizard.
I need to get index of specific page by its type (I don't know exactly which index would that page have).
Something like this:
var indexAdvanced = MyCarouselView.GetIndex<ContentView>(typeof(AdditionalDefectParametersContentView));
but of course, this code doesn't work. While creating this question, I've got an idea with using CarouselView's ItemsSource. How to do it properly? TIA.
By the way, I've already found an answer. >_<
The resulting code is:
// My CarouselView consists of ContentViews
_indexAdvanced = MyCarouselView.ItemsSource.Cast<ContentView>().
IndexOf(view => view is AdditionalDefectParametersContentView);
So it works!
Don't know what should I do: delete this question or leave? Maybe It would be useful for somebody, so I'll leave it for now.
i want to display the data into DataGrid manually in VB6, source of data is not from database or other source. I have created the column, like this:
For i = 2 To 4
DataGrid1.Columns.Add i
Next i
DataGrid1.Columns(0).Caption = "No"
DataGrid1.Columns(1).Caption = "Subdataset"
DataGrid1.Columns(2).Caption = "Dimension"
DataGrid1.Columns(3).Caption = "Check"
DataGrid1.Columns(3).Caption = "Detail"
but i can't add row and add value into it, i have tried like this:
Me.DataGrid1.AllowUserToAddRows = True
DataGrid1.Row = DataGrid1.Row + 1
then i got error
Please tell me if anybody can help me, thank you
Not only is DataGrid designed to be a bound control, it doesn't support unbound use. Says so right in the doc. So, the short answer is that you can't do what you are trying to do, because it's designed to display values from a database.
Instead, you'll want to use the MSFlexGrid control (Not the MSHFlexGrid control, although some of the doc confuses them), which you can read about here. Suppose you play around with that (the AddItem method is the fundamental piece you need to work with) and post back with specifics if you have problems.
Once you have added the table (DataGrid) right click select edit then you can insert columns:
unfortunately I can't find any help concerning to my specific problem.
I try to simplify it:
My grid consists of a shown column (A) and a hidden column (B) and other shown columns as well (C,D). With a custom button I can switch between these two columns, so that A is hidden and B is shown and vice versa.
My aim is as follows:
If the width of (shown) A has been changed, the width of (hidden) B should also be changed.
My current way to realize this this:
resizeStop: function () {
var $self = $(this);
shrinkToFit = $self.jqGrid("getGridParam", "shrinkToFit");
$self.jqGrid("setGridWidth", this.grid.newWidth, shrinkToFit);
var a = $self.jqGrid("getGridParam","colModel");
$self.jqGrid("setColWidth", "customers.name_short",a[2].width);
},
I works, but I have to wait for a wile and in addition to that I get the following log: "too much recursion". It seems that the function setColWidth is called more than 300 times.
I analyzed the code of setColWidth but I could not find any hint where it would call itself.
Can anybody help me?
Thanks in advance!
I suppose that you use my method setColWidth from here and the answer. It's wrong to use it inside of resizeStop callback.
You wrote: "With a custom button I can switch between these two columns, so that A is hidden and B is shown and vice versa." It seems to me that you need place one call of setColWidth method directly after you makes the column A or the column B visible (in the click event handle of your custom button). It should solve the problem.
UPDATED: The following demo http://jsfiddle.net/OlegKi/m7f9ghwq/18/ demonstrates the approach.
I have:
1.) What should I type in this.control() for getting the reference to the grid panel?
My plan is, when user double clicks one row, new tab is created. I already have code for creating new tabs but I just need to get reference to the grid panel.
Something like this:
'viewport > westpanel > accordion > gridpanel': {
doubleclick: function...
}
2.) Let's say that I gave an ID to the grid panel. How can I get reference in this.control using .get method?
3.) How can I be sure that I've got the right reference? Can I console.log() - it or something like that?
I would know how to do this without MVC but here I need help. :)
Thank you! :)
It is quite easy once you understand how to use it. First you should read the API about the ComponentQuery cause that is what is used within the control.
this depends on your components. You so can go by the xtype 'panel > grid': {itemdblclick:this.yourCallback}
the recommend way if you can't define a really unique path by xtypes '#myID': {itemdblclick:this.yourCallback} using defined refs within the control is not possible in the currently release, as far as I know.
Use Id's instead of just xtypes '#myID > grid': {itemdblclick:this.yourCallback} or define additional params '#myID > grid[customProp=identString]': {itemdblclick:this.yourCallback}
I have a pivot page, with one fixed pivotitem, and depending on data, a dynamic number of additional pivotitems. The fixed pivotitem keeps a hyperlink list of the new pivotitems created, and the idea is to click any of the links and navigate to that pivotitem.
It would look something like this:
FixedItem | DynamicItem1 | DynamicItem2
link: DynamicItem1
link: DynamicItem2
The problem I am facing is with the hyperlink click, it doesn't take me to the respective pivotitem, but instead takes me to the pivot page with no dynamic pivotitems. I am using the following code for navigation:
hyperlink.NavigateUri = new Uri("/MainPage.xaml?name=" + p.name, UriKind.Relative);
where p.name is the name of the pivotitem. I am not sure if this is the right syntax, but what's confusing is that all the created pivotitems get lost, leaving only the fixeditem - as if it was opening a new instance of the pivot page.
Then, in the OnNavigatedTo I tried the following:
if (NavigationContext.QueryString.ContainsKey("name"))
{
// URI is '/page?name=PivotItemToSelect'.
string selectedPivotItem = e.Uri.Query.Split('=').Last();
// Match PivotItemToSelect with the PivotItem's Name.
PivotItem pivotItemToShow = pivot.Items.Cast<PivotItem>().Single(i => i.Name == selectedPivotItem);
pivot.SelectedItem = pivotItemToShow;
base.OnNavigatedTo(e);
}
On the first line, I get an exception that this operation cannot be done on a "relative" URI. Any other way I could that information?
If I change the pivotitem name to a number, say i, and pass that i as the index, I got the following code to work as the _click method of the hyperlinkbutton - but in real usage the name will most likely be a text string:
pivot.SelectedIndex = int.Parse(i);
I am not sure how totally off the track I am, and would appreciate any pointers in the right direction.
Thanks.
The correct way to access the QueryString in your OnNavigatedTo event is like this:
string selectedPivotItem = this.NavigationContext.QueryString["name"];
Using a Pivot control for your navigation like this seems very strange, but since I know nothing about the context of your app, I'll assume you have chosen it for a reason.
If you are designing an app with a dynamic list of items to navigate to, it would be better to have a single page for your link list and a single detail page that can use the query string to bind to the specific object you are wanting. This will perform better and make more sense to your users. But again, I don't know the context of your app or your reasoning, so that's up to you! :)
