LoadonDemand display LoadingPanel

[Rizwan]

Hi

   I am using rad tree to load more then 1000 nodes on demand, during this time instead of displaying node with ajax image , I want to display Loading panel which will cover entire page so user cannot click any where else during this time, I dont see any option in tree to use loadingPanel instead.
Can you please help me out on this ?

Best Regards
Rizwan Bashir

Hello Rizwan,

Please take a look at the "Ajax / Explicit Show/Hide" online demo.

Hello Rizwan,

You can use the Ajaxify for the the control on the rebind/load of the TreeView.
You cna use below code :

<AjaxSettings>
    <telerik:AjaxSetting AjaxControlID="btnLoad">
        <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="RadTreeView1" />
            <telerik:AjaxUpdatedControl ControlID="Label1" />
        </UpdatedControls>
    </telerik:AjaxSetting>
</AjaxSettings>
