[Solved] C# Winform RadDropDownList contol allways scrolls to bottom of list when user clicks on the arrow at the left.

[Roger]

There is nothing in the textbox, but I do have AutocompleteMode to Suggest.  It also did this with None.

The control is bound to a DataTable.

any suggestions on helping solve this would be appreciated.

 

* Also it looks  like the "Blank" is at the bottom instead of the top.

Blank is not an option I added to the control.

 

Thanks,

Meant to say Arrow on the right.

 

I also now notice that each time I click the arrow on the right to open the dropdown I get a different action.  1st time it scrolls to the end, 2nd time it scrolls to the top and continues going back and forth.

I did try to Update to the latest version of Telerik Winform controls, but then the drop down doesn't work at all.

I am currently on Version.  2026 Q22  (2026.2.520.462)

Hello, Roger,

Thank you for reaching out to us!

I am not able to observe the reported behavior regarding RadDropDownList. I have attached a sample project with several items. Is it possible to replicate there the undesired behavior that you experience?

In our Q2 2026 (2026.2.702) version, there was an issue that affected RadDropDownList, but it is already fixed in our preview version 2026.2.715. To benefit from the fix, please upgrade to version 2026.2.715-preview of our components.

Looking forward to your reply.
