Update control on condition

[Kaushal]

Hi ALL,

          On my web page i have RadContexMenu with two static value and after that bind from database. On same page i have one RadGrid.

          When user click on any of the static value then i dont want to update RadGrid, but when user try to select any value which bind from database on ContextMenu then i have to update my RadGrid.
 
          I had used AjaxLoadingPanel also, which would be affect only when user select any value which bind from database on ContexMenu.

          Please help me.

Here i am defining my code.

  

<telerik:RadAjaxManager runat="server" ID="RadAjaxManager1" OnAjaxRequest="RadAjaxManager1_AjaxRequest"
        ClientEvents-OnRequestStart="RequestStart" ClientEvents-OnResponseEnd="ResponseEnd">
  <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="FavouritesMenu">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="FavouritesMenu" />
                    <telerik:AjaxUpdatedControl ControlID="RadGrid1" />
                    <telerik:AjaxUpdatedControl ControlID="StatusBarLabel" />
                </UpdatedControls>
            </telerik:AjaxSetting>

                            <ExpandAnimation Type="None" />
                            <CollapseAnimation Type="None" />
                        </telerik:RadContextMenu>
 <telerik:RadGrid ID="RadGrid1" runat="server" OnNeedDataSource="RadGrid1_NeedDataSource"

Hello Kaushal,

The described approach could not be implemented using RadAjaxManager control as you should set the whole RadContextMenu control to update the RadGrid no matter of the chosen items. You could try implement you own custom logic to check what exactly item is chosen and initiate Ajax request explicitly.

All the best,
