Postback on checkbox check changed

[Dirk Haucke]

Hello,

how can i get a postback when clicking the checkbox in a radlistbox? I know it's currently not built in but how can i add this?

I am sure there are many ways to do this. I like Javascript:

    <script
        language="javascript">
        function OnClientItemChecked(sender, eventArgs) {

            __doPostBack('', '');
        }
    </script>

    <telerik:RadListBox
        ID="RadListBox1"
        runat="server"
        CheckBoxes="true"
        OnClientItemChecked="OnClientItemChecked">
        <Items>
            <telerik:RadListBoxItem
                runat="server"
                Text="RadListBoxItem1" />
            <telerik:RadListBoxItem
                runat="server"
                Text="RadListBoxItem2" />
            <telerik:RadListBoxItem
                runat="server"
                Text="RadListBoxItem3" />
            <telerik:RadListBoxItem
                runat="server"
                Text="RadListBoxItem4" />
            <telerik:RadListBoxItem
                runat="server"
                Text="RadListBoxItem5" />
        </Items>
    </telerik:RadListBox>

Look for __doPostBack with javascript
This link is pretty useful as well
