I am using a tree view and a scheduler. I use RadAjaxManager to use Loading Panel. I wanna do is while drag a node from treeview to scheduler the Loading panel should be visible.
This is my code
<
telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="RadScheduler1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadScheduler1" LoadingPanelID="RadAjaxLoadingPanel1" />
</UpdatedControls>
</telerik:AjaxSetting>
<telerik:AjaxSetting AjaxControlID="RadTreeView1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadScheduler1" LoadingPanelID="RadAjaxLoadingPanel1" />
</UpdatedControls>
</telerik:AjaxSetting>
<%
--<telerik:AjaxSetting AjaxControlID="ContMenuAppointmentClick">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadScheduler1" LoadingPanelID="RadAjaxLoadingPanel1" />
</UpdatedControls>
</telerik:AjaxSetting>--
%>
</AjaxSettings>
</telerik:RadAjaxManager>
By using this code i struck in Javascript Error. The error is below
First time i found
Microsoft JScript runtime error: Sys.InvalidOperationException: A control is already associated with the element.
Second Time i do the same action i found
Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'RadScheduler1Panel'. If it is being updated dynamically then it must be inside another UpdatePanel.
So kindly help me to overcome this.
Regards,
Leo.
