I have an instance of RadComboBox set to do autopostback, but I would like to be able to change the value of the selected item through javascript without forcing an autopostback on the client or triggering a "Selected Item Changed" event on the server at the next postback.

Is there any good way to accomplish this?

Thanks

Hi Jason,

You can change the value of ComboBox item by using "set_value" method. Please use the JavaScript below.

JavaScript:
function changevalue()  
{  
    var combo = $find("<%= RadComboBox1.ClientID %>");  
    combo.set_value("New Value");   //setting the value  
    combo.commitChanges();          
    var temp=combo.get_value();     //accessing the value  
    alert("New value for selected item: "+temp);  

Thanks,
Princy.

Unfortunately this does not work for me.   I need to be able to change the selected index without triggering an autopostback.

Thanks

Hi Jason Brunken,

You could set the AutoPostBack property of the ComboBox to false to disable the immediate postbacks done on certain client-side events (chaning the selected index for instance).

Please reconsider your requirements.

All the best,
