    for simplicity's sake, i would like to call the same javascript function upon the onclientselectedindexchanged event of all the radComboBoxes in my radgrid's popup user control and run some code if the selected item's text = "OTHER". the function is displayed below:
    function OnClientSelectedIndexChanged(sender, eventArgs) {
        var item = eventArgs.get_item()
        if (item.get_text() == 'OTHER') {

    sender.get_id() returns results like:


    how can i get just the "RadComboBox_XXX" portion of the result from get_id(), or do i have to use some other method?

    Hi Alex,

    I would suggest that you set the ClientIDMode="Static" property of the RadComboBox that will render its id as it is set in the markup. Thus, you can get the id of the control only.

    Kind regards,

    kate, thanks for your response.

    the clientIDMode of the page was set to static already, and I thought that would be enough.
    I instead set the clientIDMode of each control and that did it for me.

    thanks for your help.
