I have a combobox that gets a default item set whenever the data for the combobox control is null. For example a combobox with a list of states for the user to select from. If no valid data exists, the user is presented a default item that says "Select State". If valid data exists, the default item is not set and the data value is set to the combobox.

Our combobox is set to autopostback and update a radlistbox of available items to select from. However, if "Select State" is visible in the combobox and the user selects a state, the SelectedIndexChanged event is not fired and as a result, the radlistbox is not filled with the data. However, if the combobox is changed again to a different state, then the event fires. If valid data is the selected item in the combobox and there is no default item, then the event is fired.

Understanding that the DefaultItem isn't part of the indexed items in the combobox, I can *sort of* understand why the event isn't firing, however, that doesn't resolve the issue that I need to postback whenever the user selects a valid item from the combobox.

How can I get a postback whnenver an item is selected in a combobox (not the default item) when the value being changed from is the default item?

Hi,

I was adding my style sheet in the client code of my page and my radscheduler looked fine. Then I decided to use RadStyleSheetManager to add my style sheet from the code behind and the radscheduler  in my page lost all of its default styles... Do I need to load them too in addition to my style sheet and in that case how do I do that?

Hi,

I'm using RadTileList and creating the tiles dynamically based on user inputs. If user clicks on add, we will capture the data and create a tile and will Render in the UI. User can delete a tile, create a new tile with some inputs. We require Drag and Drop functionality and need to store the position of each tile. I'm using the below method to capture the position. ProjectAssetsTileList.GetAllTiles() is giving always "0" on page load. Please suggest a way to persist the TileList Tiles and Order.

Hi,

I have a requirement to display a radwindow for every selected row in the radgrid. The content of the window is different for each row.
When I select multiple rows and click on a button, I need to display the radwindow one after the other. For example, if I select 5 rows and click on the button, I need to display the window 5 times.

In the button click event, I have the below code. 

foreach (GridDataItem item in grid.SelectedItems)
{
    window.VisibleOnPageLoad = true;
    // Load the content for the window
}
However, the window gets loaded only once after completion of the foreach loop. 

I also tried setting the Visible property of the window instead of using VisibleOnPageLoad. But in this case, the window is not displayed at all. 
Is there a way to display the window first and then continue execution of foreach loop?

Thanks in advance.

Hello,

 I am developing ASP.NET Usercontrol which includes a RadListView with ASP.NET DataPager.

 

I tried the same example shown it following page.

 http://demos.telerik.com/aspnet-ajax/datapager/examples/raddatapagervsdatapager/defaultcs.aspx

 

I am binding the RedListView in Page_Load event of the Usercontrol with checking the IsPostBack == false value.

When I place the Usercontrol in Page and run the application. It display the first page perfectly but when I change the Page using the pager the RadListView control will be hide and all data is cleared out.

 I also tried by removing the IsPostBack condition and found that when I click on 2nd page it display the double records then the defined Pagesize. Same with the 3rd page, it display the 3 times more records then the pagesize.

 

I replaced the ASP.NET DataPager with the RadDataPager but still I am facing the issue.

 

Any urgent help would be h​highly appreciated.

 

Thanks,

I have been trawling for an answer to this question but nothing is coming up.

In code behind with a RadToolBar I can use

 

GetCheckedGroupButton()

 

to identify which item is "clicked"

 

I cannot find any reference to a javascript version of this?

 is there one?

thanks

Hello,

I just downloaded the latest version of UI for ASP.Net Ajax v2015.2.623.45 BTW, I also have the .net framework 4.5.1 if you need that info.

Since downloading that new Telerik version I noticed that the Radgrid Paging is now broken. If I turn the paging off, the grid loads fine. However if I turn the paging on and run very basic code like below, I get a server error talking about a key that cannot be null. It does not tell me which key, but I can see it's some sort of a dictionary entry that has a key that's null. I no longer have the exact error verbiage. I have since reverted back to the prior version of v2015.1.401.45 and the paging is now working again.

nString="<%$ ConnectionStrings:Conn %>"
ID="DataSource1" runat="server"></asp:SqlDataSource>

    </form>

</body>
