I have three RadCombo boxes that interact with each other depending on what the boxes in front has selected.  The combination of Radcombo make up a database product filter of three different search values to populate a repeater control via Radhttppanel.  That is working great (lightweight and quick). 

I am trying to reset box 2 and 3 to default item (message like width and Length) when I change the selected values in box 1 (material).    I look up and down and inside and out the online docs and did not see anything for setting the selected value on the client side.  It could be simple and I am just  missing it.

Thanks for any help.

Hello David ,

You can use the select() method of RadComboBoxItem to do that. Check the documentation for more information.

Hi Kamen,

function SelectComboBoxItem(itemText)
{
 var combo = $find("<%= RadComboBox1.ClientID %>");
 var item = combo.findItemByText(itemText);
 if(item)
 {
   item.select();
 }
}

I guess I need to look for the item by text then select it.

Thanks,
David

Hello David ,

No, you can just select the item you want by its index:
function selectFirstItem() {
    var combo = $find("<%= RadComboBox1.ClientID %>");
    if (combo)
        combo.get_items().getItem(0).select();
}

Kind regards,

Thanks, I am just getting back around to the dropdowns after working on other sections of the app like the dynamic wall color changer.  That is working great now.  RadCombo combine with the RadXmlHttpPanel  makes a great floor sample filter for this app.  Hopefully I will have the new web app launch in the next week or so.
