how to put the loading panel?

[Henry]

there is one radcombobox and radgrid in the page, when the selection changed in the combobox, it will reload grid base on selection. the grid takes a while to load, now during this loading time, the user will feel like nothing happening... how can I put a loading panel above the grid after radcombobox is selected?

the grid itself does have loading icon in the bottom left corner, it shows when the action is initiated from the grid(for example, filtering), but it doesn't when the action is out of the grid (in this case, the action is from radcombobox).

thanks.

Hello Henry,

Try with below code snippet.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
          <AjaxSettings>
              <telerik:AjaxSetting AjaxControlID="RadComboBox1">
                  <UpdatedControls>
                      <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                  </UpdatedControls>
              </telerik:AjaxSetting>
          </AjaxSettings>
      </telerik:RadAjaxManager>
      <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
      </telerik:RadAjaxLoadingPanel>

Note : if you already used RadAjaxManager then use RadAjaxManagerProxy.

Thank you Jayesh, it works.

how about the combobox itself? currently I set to EnableLoadOnDemand="True", when the items in the combobox is loading, it shows the text "loading...", how can I put a loadingPanel too?
