I am getting an error(see attached files) while trying to select item from grid dropdownlist.
Step to reproduce:
1. This is occuring when we trying to select an item from dropdownlist very fast e.g
- Click on add new row or click on dropdown cell and press B as I have item starting from B and then click outside of the row(somewhere in grid) do it repeatatively.Try to repeat the steps as fast as possible.
2.After few rows added you will get attached error which is not going inside try and catch.
I am using below grid events:
1.
Private Sub rdgrdvSeachAddUpt_CellBeginEdit(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.GridViewCellCancelEventArgs) Handles rdgrdvSeachAddUpt.CellBeginEdit
Dim lobjMessage As New Message
Try
''Find out dropdown control in Grid
Dim editor = TryCast(e.ActiveEditor, RadDropDownListEditor)
If editor IsNot Nothing Then
''If yes find out its element
Dim editorElement = TryCast(editor.EditorElement, RadDropDownListEditorElement)
If editorElement IsNot Nothing Then
''If its column name is radcmbCriteriaType
If e.Column.Name = "radcmbCriteriaType" Then
''Add handler to get dropdown event
AddHandler editorElement.SelectedIndexChanged, AddressOf editorElement_SelectedIndexChanged
End If
End If
End If
2.rdgrdvSeachAddUpt_CellEndEdit
3.rdgrdvSeachAddUpt_CellValueChanged
4.rdgrdvSeachAddUpt_Click
5.rdgrdvSeachAddUpt_UserDeletingRow

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

I was just about to write that attachments in forums are not possible (except images), when I noticed that you had submitted a support ticket where your file is correctly attached. We will reply there soon.
Greetings,Nikolay

You can now find the answer to your question in your ticket. I am pasting the answer here in case our community is interested in the case:
I tried to reproduce the described issue in a sample project, but to no avail. However, I noticed something that potentially can lead to an issue.
In order to optimize the performance of RadGridView and its editors, we are reusing the editors instances.
In your CellBeginEdit event, you are subscribing the editor element instance to SelectedIndexChange, but please not that you are never unsubscribing from it. Editing a drop-down cell several times would result in the SelectedIndexChanged event being fired the same number of times per just one change of the selected item from the drop-down. Therefore, I would suggest that you first unsubscribe from the event and then subscribe to it:
RemoveHandler editorElement.SelectedIndexChanged, AddressOf editorElement_SelectedIndexChangedAddHandler editorElement.SelectedIndexChanged, AddressOf editorElement_SelectedIndexChangedA bit off topic, I would also recommend using our code snippet tool from the ticket editor that will allow you to format the code that you send.
I hope this helps.
Kind regards,
Nikolay
