Using UI for ASP.NET AJAX Q3 2015 along with VS 2013. I am using below link as a prototype.
I modified it to fit my requirements. I would like to use RadAjaxLoadingPanel and RadAsyncUpload together on the button click event of the below button (attached AsyncUpload - Validation.png)
<telerik:RadButton runat="server" Skin="Silk" ID="BtnSubmit"Text="Validate the uploaded files" OnClick="BtnSubmit_Click"></telerik:RadButton>
On Button Click event, the routine uploads the file as well as runs SQL Stored procedure and on return Stored procedure also executes SSIS packages.
The whole process takes some 5-7 minutes that is the main reason I would like to display the Loading Panel during the execution phase. Instead of IE “Waiting for Local host” message. If I do use RadAjaxLoadingPanel, after the process complete, current form stays open, does not go to attached 2nd screen (Attachment 2.png).
Below is my complete code. Thanks for any help
