RegisterClientScriptBlock not working

Question

I have a fileupload control:

XML

<asp:FileUpload ID="file" runat="server" Width="100%" />

Then I register some javascript in the codebehind:

XML

this.Page.ClientScript.RegisterClientScriptBlock(typeof(string), "file", "<script language=javascript> function BrowseClick() { "
  + "document.getElementById('" + this.file.ClientID.ToString() + "').click(); return false; } </script>");

Then I add the function to the attributes of an ASP.NET button:

C++

this.btnDownload.Attributes.Add("onclick", "BrowseClick");

When I click this button I expect a file dialog to open, but nothing happens. Why?
Also, I want the fileupload to open as a "save as" dialog instead of a "file open" dialog. How can this be done?

when you look at the html source in the browser during debugging, what do you see?

I did mention earlier something about "javascript:BrowseClick();", could this apply here?

"javascript:BrowseClick();" works!! Thanks. Now could you please also tell me how to open the fileupload dialog as a "save as" dialog instead of a "file open" dialog? Thanks for all your help.

Have a look at this article, sounds like the same thing you need:
File download using C# [^]

It says, for SaveAs dialog in ASP.NET you need to add these to the response header:

Response.ContentType="application/ms-word";
Response.AddHeader( "content-disposition","attachment; filename=download.doc");
