Hello,

I have a updatepanel containing a list of items based on a datasource.
the list container is a ordinary div, called listingpanel.
I have a combobox in a different div which is invisible when source is selected and saved with the combobox.

I also have a radcontextmenu with a edit button in order to bring the panel to change source in the combobox to the front.
Called "editpanel", a ordinary div.

By default the editpanel is visible and everything works fine.
When using the radcontextmenu to bring the editpanel to the front, a partial postback is triggered, editpanel is displayed but the radcombobox is not functioning, I can see the first item displayed in the list but I'm unable to change it, it wont drop and there is no hover in the combobox when i point my mouse at it, which it is by default.

If I remove the display: none on the editpanel with firebug it works, so I know there must be something with the partial postback.
in the partial postback, all the items are being rebound in the page_init method.

Any ideas ?

Thanks in advance,

Lars

Appearantly the same thing happens to radnumeric and radtextbox.
After the partial post, a textbox containing user input is always empty when checking in codebehind;

string tmp = myRadTextBox.Text; // is always empty.

Hi Lars,

Have you inspected this behavior with an asp:DropDownList? If the asp:DropDownList's behavior is different, could you send a sample page or paste the troubled code here?
