How to use RadAjaxLoadingPaanel on desired Click events?..

[Amit]

Hey everyone,

I am using a radgrid,with manual insert,delete and updates from external button clicks.I just want to know how can i use loading panel when debugger runs to these events.I am trying this--

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadGrid1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="btnSearch">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
        <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Hay"
            EnableSkinTransparency="true" Transparency="30">
        </telerik:RadAjaxLoadingPanel>

the first one is doing fine,but as i want this to be visible on btnSearch_Click.And after this OnClick event is not firing.Nothing happens.How to do this?...

Thanks

Hi Amit,

I followed your scenario and prepared a simple working project with similar functionality where the click event is fired as expected. Please examine it and let me know what is the difference in your scenario.

Hello Pavlina,

I am doing exactly the same except for that i've a little javascript enabled OnClientClick event of button.I am sending the required code to understand-- for javascript onClientClick event of btnSearch

function filterSearch()
                    {
                       var combo = $find('<%=RadComboBox1.ClientID %>');
                       if (combo.get_selectedIndex() == null)
                       {
                          alert("You must select a category before processing search!");
                          return false;
                       }
                    }

ajax manager-

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">
           <AjaxSettings>
               <telerik:AjaxSetting AjaxControlID="btnSearch">
                   <UpdatedControls>
                       <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                   </UpdatedControls>
               </telerik:AjaxSetting>
               <telerik:AjaxSetting AjaxControlID="btnShowAll">
                   <UpdatedControls>
                       <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                   </UpdatedControls>
               </telerik:AjaxSetting>
               <telerik:AjaxSetting AjaxControlID="RadGrid1">
                   <UpdatedControls>
                       <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                   </UpdatedControls>
               </telerik:AjaxSetting>
           </AjaxSettings>
       </telerik:RadAjaxManager>
       <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Hay"
           EnableSkinTransparency="true" Transparency="30">
       </telerik:RadAjaxLoadingPanel>

this is my button--

<asp:Button ID="btnSearch" runat="server" Style="float: left; color: black; font-weight: bold"
                                Text="Search" OnClick="btnSearch_Click" OnClientClick="javascript: return filterSearch();" />

i think this is not working due to client side javascript for this button.its working well for btnShowAll which has no client side javascript defined for it.The thing is that when i click on btnSearch the server side onclick click event is not called("NOTHING HAPPENS") and hence no loading panel.how to resolve this?...

Thanks
Amit

Hello Amit,

I tested the setup locally, and the control behaved as expected. Since this information is not enough to replicate the issue, you can open a formal support ticket, and send us a small project, demonstrating your setup, along with the unwanted behavior. We will review it locally, and advise you further.

Best wishes,
