    Hello Support,

      I am using v.2015.2.728.40 and are experiencing some issues with the behavior of the ToggleButton and CommandBarButton.  The issue is that when clicking on the toggle button, everything is fine for the first time.  The response time for the button progressively degrades as you continue using the button.  I was able to reproduce this problem by creating a new Project with an empty form, dropping in a CommandBar, then adding five ToggleButtons.  Set the togglebuttons to DrawImage=False and DrawText=True.  Run the application and in a circular fashion, click on the each button with a short delay in between.  You should notice that after a few iterations, the buttons become unresponsive.  This behavior is now hindering the functionality of my application.

    Thanks

    Francisco

    Hi Francisco,

    Thank you for writing.

    We do not have any reports of similar behavior. I was not able to reproduce this locally as well. This I why I have attached my test project. Could you please check it and let me know how it differs from your real setup? Could try to reproduce this with it as well?

    In addition, could you confirm that you are using the latest version of the suite? 

    Thank you in advance for your patience and cooperation.

    Hello Dimitar,

      I am using an older version (v.2015.2.728.40) to minimize changes in our development environment.  You are correct, the behavior I described doesn't happen on the new suite version (UI for WinForms Q2 2016)

    After some minor changes, the update to the new version of Telerik allows my application to run.  Doing some automated tests now I find that the droplist doesn't support the arrow keys for selection as my previous version did.  

    How do you enable arrow key or some other keyboard selection on DropDownList?

    Thanks

    Francisco

    Hi Francisco,

    Thank you for writing back.

    We haven't made any changes to the RadDropDownList behavior and you should be able to select items with keyboard despite the DropDownStyle. Can you test this in a blank new project and confirm that you are getting the undesired effect as well?

    Thank you in advance for your patience and cooperation.
