ComboBox in RadWindow holds previous state

[Richard M]

I have a RadWindow1 in my Page1.aspx page which opens up Page2.aspx in my RadWindow1.  In Page2.aspx I have a RadComboBox.  I want the RadWindow1 to always open with ComboBox1.SelectedItem = 0, but everytime the RadWindow is open, it keeps its previous state.  I tried setting EnableViewState = False, but it did not work.

Hello,

Try setting 'DestroyOnClose' property of RadWindow to "True", which will prevent the caching feature of RadWindow and to destroy the client object when it is closed.

I did try that, and unfortunately you would have to recreate the window in code behind every time you bring it up.  But I did find that if I set ReloadOnShow="true" in my RadWindow, it will reload all of the controls, and then I can write code in Page2.aspx.vb which will reset my controls to SelectedItemIndex = 0 or to "".  Thank you for your help.

Hi Richard M,

Please try replacing the RadComboBox with a DropDownList to verify whether the issue still persists.

If so, then you could try clearing the selection of the RCB whenever the Window opens (in the client-side Show event).
