RadControls for ASP.NET AJAX This example demonstrates how to use RadToolBar as a custom RadGrid Command item container. The buttons in the toolbar have CommandName values set which are internally 'recognized' by the grid when its event bubbling mechanism is triggered (after pressing a button from the command item toolbar). Thus the respective command is executed without any extra coding.
Below is a code extraction from the relevant online demo in the RadGrid:
CopyJavaScript
function onToolBarClientButtonClicking(sender, args) {
var button = args.get_item();
if (button.get_commandName() == "DeleteSelected") {
args.set_cancel(!confirm('Delete all selected customers?'));
}
}
