call ItemsRequested onfocus

[Dan Lehmann]

Hi,
I have 2 'google suggest' style RadComboBox with EnableLoadOnDemand="true". Is there an easy way to call the OnItemsRequested function every time the ComboBox gets focus?

I get the items the first time the ComboBox receives focus and if I start typing but the problem I have is the following:
1. I type something in ComboBox1.
2. I click in ComboBox2 and see filtered items based on ComboBox1.
3. I type something else in ComboBox1.
4. I click in ComboBox2 again and the old filtered items are there. It does not make another call to the codebehind handler for OnItemsRequested until I type something.

Thanks,
Dan

Hello Dan,

Try using the OnClientFocus event to make a call to the requestItems(string, boolean) method for that.
It is going to make the call to OnItemsRequested server-side event handler every time the ComboBox gets focus.

Here you can find more about using the requestItems method.

Thanks, that works!

In my RadComboBox I added:  OnClientFocus="clientRequestItems"
which calls my js fn:
function clientRequestItems(sender, args) {
    sender.requestItems(sender.get_value(), false);
}
