Disabled listbox - set selected item

[Pieter]

Hello,
In the codebehind we disabled the ComboBox and set a selected item. Via JavaScript we want to change the selected item via:

function winDialogCallbackControleren(radWindow, returnValue) {
  if (returnValue != "-1") {
    var combobox = $find("<%=rcbDocumentStatus.ClientID %>");
    var item = combobox.findItemByValue(returnValue);
    if (item) {
      item.select();
    }
  }
}

But it didn't succeed. The already selected item (from the codebehind) remains unchanged. What are we doing wrong?
With friendly greetings,

I'm not sure if you have do enable the control first and then re-disable it, but I do know that in order to persist the item to the server you have to call trackChanges() before your logic and commitChanges() afterward. You can see an example of this and more information regarding the client-side aspect of the RadListBox by following this link to a documentation article.

function winDialogCallbackControleren(radWindow, returnValue) {
  if (returnValue != "-1") {
    var combobox = $find("<%=rcbDocumentStatus.ClientID %>");
    if (combobox) {
       combobox.enable();
       var item = combobox.findItemByValue(returnValue);
       if (item) {
         item.select();
       }
       combobox.disable();
    }
  }
  else {
  }
}

This is the solution.
