Check/uncheck items on select in ListBox


Clicking on an item does not check/uncheck items.


When clicking an item, the SelectedIndexChanged event is fired and the click does not bubble up to the Checkbox element.


To make the ListBox check/uncheck the checkbox when clicking anywhere on the item, we can prevent the selected index changed event and click the checkbox element programmatically.

<telerik:RadListBox runat="server" OnClientSelectedIndexChanging="OnClientSelectedIndexChanging"  CheckBoxes="true" ID="RadListBox1">
        <telerik:RadListBoxItem Text="Item 1" />
        <telerik:RadListBoxItem Text="Item 2" />
        <telerik:RadListBoxItem Text="Item 3" />
        <telerik:RadListBoxItem Text="Item 4" />
    function OnClientSelectedIndexChanging(sender, args) {
        var item = args.get_item();
