Postback on each key press

[Duncan]

I have a combo box that allows custom text. Is there a way for the combo box to perform a postback each time the text in the combo box is updated, added to or removed from? It seems as though current i have to click away from the combo box or hit enter for a postback to occur.

Also, if the above is possible, is there a way to make it NOT postback if there are items available in the list?

Thank,
Duncan

Hello Duncan,

The desired functionality is not supported from the RadComboBox. A post-back is performed only when the control looses focus. In case you want to prevent a post-back to appear if there are items in the control you should subscribe to the client-side OnClientTextChange event and cancel it as shown below:

function OnClientTextChange(sender, eventArgs) {

    if (sender.get_items().get_count() > 0) {

        eventArgs.set_cancel(true);
    }
}
