This is not like that, that you are thinking.

You have to use AJAX for that. Beause you dont know how much time will it take for load the report.

Use AJAX UpdatePanel and Update ProgressBar.

These will resolve your problem.

For your Ref.
The UpdatePanel and UpdateProgress Controls[^]

Hi Dear, I've a serious problem, that is:
I've three asp:Contents in my content page. Content1 for head, Content2 is activated when user is logged in; By contrast, Content3 is for anonymous user.
In my program asp:UpdatePanel works properly in both content(Content2 & Content3). asp:UpdateProgress works properly in Content3(used for anonymous user) but doesn't work for Content2(used for logged in user)

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
           <asp:UpdatePanel ID="UpdatePanel2" runat="server">
                 <ContentTemplate>
                 <%=DateTime.Now.ToLongTimeString() %>
                     <asp:Button ID="Button1" runat="server" Text="Button"  OnClick="UpdateButton_Click"/>
                 </ContentTemplate>
            </asp:UpdatePanel> 
             <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel2">
              <ProgressTemplate>
                    <img alt="Loading..." src="../Images/ajax-loader.gif" />
                    Please wait...
                </ProgressTemplate>
              </asp:UpdateProgress> 
</asp:Content>

<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder2" runat="server">
    
            <asp:UpdatePanel ID="UpdatePanel1" runat="server">
                 <ContentTemplate>
                 <%=DateTime.Now.ToLongTimeString() %>
                     <asp:Button ID="UpdateButton" runat="server" Text="Button" OnClick="UpdateButton_Click" />
                 </ContentTemplate>
             </asp:UpdatePanel> 
                <asp:UpdateProgress ID="UpdateProgress2" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
              <ProgressTemplate>
                    <img alt="Loading..." src="../Images/ajax-loader.gif" />
                    Please wait...
                </ProgressTemplate>
              </asp:UpdateProgress>
</asp:Content>

I don't understand which is my fault. Could you help me?

Thanks a lot

No specific error show from compiler. When I click update button, page is partially updated. But progressing message (with Image) never show for a logged in user. Interest that their is no problem for anonymous user.

I tall you again
In my program the Content2 is activated only for logged in user. Is it problem?

Because, I guess, You are using Two Data Source for GridView1. One From Code Behind. and Another is on ASPX PAge.

As per my article goes, Displaying Image in Gridview from Database[^] There is only one datasource that is created only on CodeBehind.

Remove DataSourceID of GridView From aspx page.

Error is self describing.look at that. Smile | :)

I think you defined DataSourceID in the html.Check your html for GridView and remove that.

Show us the code of GriView from aspxpage. And DataBind code from Codebehind page.

put a breakpoint at

GridView1.DataSource = ds;

and check if ds is filling correctly with data.
