Changing icon in GridView, and back

[gianfranco dalfiume]

Hi all!
I have a gridview with a templatefield and an imagebutton

<asp:TemplateFi eld>
<ItemTemplate >
<asp:ImageButto n ID="Riepilogo" runat="server"
CommandArgument ="<%#((GridView Row)Container). RowIndex%>"
ImageUrl="~/img/search.png"
CommandName="ri epilogo" ToolTip="Riepil ogo attività impianto"
onClick="prova" OnClientClick=" src='img/blue_loader.gif '; Visible='True'"/>
</ItemTemplate>
</asp:TemplateFie ld>

When i click that imagebutton, the onclientclick event changes the standard
image to a "waiting" animated gif.

The code for CommandName is something like that:
....
Response.ClearH eaders();
Response.Clear( );
Response.AddHea der("Content-Disposition", "attachment ;
filename=output .pdf");
Response.Conten tType = myStuff.getAppS etting("Content TypePDF");
Response.Flush( );
Response.Binary Write(pdf);
Response.End();
....

This generates a PDF files that pops up for the download.

Now i have to change the image back to normal (not waiting). How do i
accomplish this?

Thank you in advance.

becuase the request is a file download, there is no browser notification
javascript can get of when the domaload is done. you can use ajax to poll the
server to for when the download is done. be sure the poll is non-session
page.
