RegisterStartup Script after Response.WriteF ile?

[MJP]

I have a button which kicks off the generation of a report after which
the file will be downloaded. The report generation can take a long
time, so client side onclick event of the button also makes a <span>
tag visible which contains a nice message to the user thanking them
for their patience. Of course after the report has been generated and
downloaded this message should be removed. However, the
RegisterStartup Script isn't working after calling Response.WriteF ile.
Any alternative solutions/suggestions to solve this issue?

Code:

protected void btnExecute_Clic k(object sender, System.EventArg s e)
{

CreateReport();

Response.Append Header("content-disposition", "attachment ;
filename=<filen ame>");
Response.WriteF ile(<filename>) ;
Response.Flush( );

Page.RegisterSt artupScript("To ggleWait",
"<script>javasc ript:spnMessage .style.display = \"none\";</script>");
}

You can't register RegisterStartup Script, because you already sent a
file to HTTP response...

Remove the following code:

/*
Response.Append Header("content-disposition", "attachment ;
filename=<filen ame>");
Response.WriteF ile(<filename>) ;
Response.Flush( );
*/

and modify your RegisterStartup Script as per

Page.RegisterSt artupScript("To ggleWait",
"<script>javasc ript:spnMessage .style.display = \"none
\";window.open( '<filename>'); </script>");

It should hide the spnMessage span tag and open the file in a new
window. If you like to force a Save As window to be shown, you need to
have another page Download.aspx where you can have

Response.Append Header("content-disposition", "attachment ;
filename=<filen ame>");
Response.WriteF ile(<filename>) ;
Response.Flush( );

Then open that page using window.open('Do wnload.aspx?
filename=<filen ame>');

Should work, I think.

Thanks Alexey, that does work.

However, I of course now need to close the window that I open to run
Download.aspx after the file has been written to the HTTP response,
and since RegisterStartup Script won't work after writing the file, I
essentially still have the same problem....

I think that when you have a content-disposition=att achment and user
has selected Save button, the popup window will be closed
automatically.
