Hi

I'm trying to use jquery to update a RadCombobox and set its selected index by using RadComboboxItem.Select().

The updating works fine, but when I use RadComboboxItem.Select() where RadComboboxItem.get_index()=0, RadCombobox.get_selectedIndex() returns the old index.

If RadCombobox.get_index()>0 it works fine.

 

 function SetSelection(radCombo, selectedValue) {
radCombo.trackChanges();
radCombo.clearSelection();
var item = radCombo.findItemByValue(selectedValue);
if (item != null) {
item.select();
alert("id=" + radCombo.get_id() + " item.index=" + item.get_index());
radCombo.set_text(item.get_text());
radCombo.set_value(item.get_value());
}
radCombo.updateClientState();
radCombo.commitChanges();
alert("id="+radCombo.get_id()+" selectedValue="+selectedValue+" index=" + radCombo.get_selectedIndex());
}

Hi Again.

I've just found out, get_selectedIndex is not working when RadComboboxItem.get_index()>0 either.

Or could it be RadComboboxItem.select() that isn't working?

I've found the answer myself.

The index was prevented from changing because I had an onClientIndexChanging handler with args.set_cancel(false), if I was handling the clientIndexChange of another RadComboBox.

Hello Rene,

I'm glad you've managed to root out the problem by yourself. Please note that in such cases, it is of tremendous help to disable any AJAX on the page if present (RadAjaxManager, RadAjaxPanel, UpdatePanel, etc.). Then you can enable your script debugger (FireBug or F12) to see whether there are any errors interfering. When AJAX is enabled, the errors are being hidden or encapsulated, which may lead to omission.

For additional client-side examples using the Telerik API, you can refer to our documentation articles:
http://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/radcombobox-items/working-with-items-in-client-side
http://docs.telerik.com/devtools/aspnet-ajax/controls/combobox/client-side-programming/overview‚Äč

Hope this helps.

Regards,
Eyup
