Postback only when Expand?

[Raymond]

Hi,

Is there a way to send a postback and do serverside code when the user expands the panel but no postback when the panel is collapsed. Now I use the event OnItemClick couse there are no OnExpand and OnCollapse but then there are allways a postback - no good.

On Expand I load stuff inside the panel but on collapse no such thing needs to be done.

Hi Raymond,

Try the following approach to achieve the functionality.

ASPX:

<telerik:RadPanelBar ID="RadPanelBar1" OnClientItemClicking="OnClientItemClicking" OnClientItemExpand="OnClientItemExpand"
 runat="server" OnItemClick="RadPanelBar1_ItemClick">
</telerik:RadPanelBar>

JavaScript:

<script type="text/javascript">
function OnClientItemExpand()
{
    __doPostBack('<%= RadPanelBar1.ClientID %>'  , '');
}
function OnClientItemClicking(sender, args)
{
    if(args.get_item().get_expanded())
    {
        args.set_cancel(true);
        args.get_item().set_expanded(false);
    }
}
</script>
