need javascript to set an selected index for RAD combobox to 0
+2
A:
Have you tried "ClearSelections"?
var combo = $find("<%= RadComboBox1.ClientID %>");
combo.clearSelection();
EDIT
Give this a shot:
var combo = $find("<%= RadComboBox1.ClientID %>");
var comboItem = new Telerik.Web.UI.RadComboBoxItem();
combo.trackChanges();
combo.get_items().getItem(0).select();
combo.commitChanges();

By 0 index do you mean the first item (which has a selectedindexid of 0)? If you have a real value saved in the 0 position, then to keep in the Telerik way of handling it, use the "selectedtext" and "selectedvalue" fields to get which item is selected regardless of whether they entered a new item or selected an existing item.

yes I mean the selectedIndexid of 0.can I have the java script the this. i made it work with codebehind. But I need the same functionlity in client side.Here is the psudoOn event OnClientDropDownClosed check if the typed value is there or not, If yes display the value else by default select the selectedindexid of 0

You can enter custom text and get it through the client-side text property, but I don't know if you can have custom text and a selection at index zero, as that means two different things... It may need to be at -1 or null (whatever the client-side default is). I modified my response above.

Hey,
You should be able to do:
var combo = $find("<%= RadComboBox1.ClientID %>");
combo.get_items().get_item(0).select();
I believe you use get_item() to get the specific item. There is a selected index, but I've seen the preference being to use the select method instead on telerik forums.
EDIT: The RadComboBox uses the text property to reference the text in the combo, since the text isn't required to be an item in the list. You should test, because it's probably a selected index of -1. So, you can check and see if the selected index is a -1 or other value (not 100% sure if it's -1 or null on the client-side) and then programmably perform the selection. So is that the right response though, because I think the control then may wipe out your text...
