Hello,

 I am dynamically creating a RadDropDownList and I add a handler to the KeyDown event. When this event gets called the sender is a RadDropDownListElement. How can I find the RadDropDownList that the element belongs to? I've tried the obvious properties like "parent" (It is a RadElement) with no luck.

 Thanks!

Hi, 

There's a graphical problem with RadPageView Q1 2015.

I tested it on a new project (cf screenshot)

When on ExplorerBar mode, you have more than 1 Page and use scroll button of your mouse, the component blinks.

Happens too if your scrollvalue=0 and you move up and scrollvalue=max and you move down.

 

So I know how to return any value using the CurrentRow. Let's say a user has one row selected, and they right-click on a different row, I need to retrieve the value from that row. I've been looking at CurrentRowChanging & Changed as I suspect I need to capture the value there. I think my issue is the value being returned now is the value from the previously selected row and I'm not aware of the event trigger hierarchy.

 Any help? Thanks

I'm trying to create GridViewComboBoxColumn that works like a RadComboBox with the CheckBoxes property set to True.

Reading through this post, I cannot find the RadGridView_RowLoaded event. 

Under the section "Customize the DropDownListEditor in GridViewComboBoxColumn​" in this post, would I do something like that to create CheckBoxes? From this example, it looks like it would affect all GridViewComboBoxColumns. How would I make it only affect the specific column?

Hi,

 

When i try and refresh the grid's datasource after deleting a row, i get the following error:

A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in mscorlib.dll
Additional information: Index was out of range. Must be non-negative and less than the size of the collection.

Telerik version: 2015.3.930.40
Framework version: 4.0
Operating system: Windows 10 

 

Here is the refresh code:

Stack Trace:

   at Telerik.WinControls.UI.RadGridView.EndUpdate()
   at DeedMagic.Modules.ucDataEntry.RefreshGrid()

It works fine if i add a row, it only happens when i try to delete one. I thought maybe it had to do with the selected rows, so i tried clearing them out but i still get the error. Any suggestions?

 

Thanks

Hi,

I noticed I have those package load failures repeated at least once during the loading of Visual Studio 2008. That's the first load after the installation of Q2 2012 release.

I'm not sure whether this is related. But I'm not sure what need to be done.

When I'm prompted for whether to disable loading of package, I just clicked No, so every time they will prompt me the same errors multiple times when I restart my Visual Studio 2008.

I also noticed that the Q2 release still crash Visual 2008 (even though it's not running) and require me to send crash reports to Microsoft. Maybe Telerik need to look into this (but I'm running an older version of OS, Windows XP SP3). I'm not sure whether the latest installers are compatible with Windows XP or not. Hopefully Telerik will solve this installer issues in the next release or minor release.

Thank you.

I'm trying to programmatically add a tab to the Ribbonbar at runtime. It all works fine when the Ribbonbar is expanded. But when I add a tab to a collapsed Ribbonbar the new tab is not visible until I click the button to expand the Ribbonbar again. Here are the steps to reproduce:

1.Create a new Visual C# -> Telerik Windows Forms Application

2.Drag a RadRibbonBar control onto RadForm1

3.Create a single tab "First Tab" (otherwise you cannot collapse the ribbon)

4.Drag a button onto the form and add the following code to the click event handler:

5.You should end up with something like the attached png file.

6.Run the project and click the button. You should see the new tab is created and selected.

7.Close the project and run it again. This time collapse the ribbon before clicking the button. No new tab is visible on the ribbon. Even if you click on the [First Tab] to show the full ribbon.

8.Click the expand ribbon button on the right and the new tab will then appear.

I've tried adding lines like Application.DoEvents() or this.Refresh() or this.radRibbonBar1.Refresh() but it doesn't make a difference.

Any help would be much appreciated.

Thanks,

John
