POST & GET Behaviour

I created a sample aspx page with a server side Button Control. OnClick event of Button streams an excel file to the client via the following code..
response.Buffer =true
response.Charset = ""
response.ContentType = "application/vnd.ms-excel";
response.AppendHeader("Content-Disposition", "attachment;filename=sample.xls")
response.Write(data)

If the above page is accessed and button is clicked, IE browser throws up TWO Open/Save Dialog boxes.

If i change the "form" attribute "method" to "GET" instead of "POST", IE browser prompts the user with only ONE Open/Save Dialog box. However i like to have the form to have POST mechanism rather than GET and at the same time want the browser to prompt the user only once with Open/Save Dialog box... Any ideas

Thank

Do you have a public url which exhibits this? I'd like to take a look.

SamplePage.aspx provided in previous post has <method> attribute of form set to "GET". The problem occurs when the attribute is "POST"

Thank

Well, I am sorry for not mentioning about the "namespace". "SampleReport" is the namespace. You can do global replace of "SampleReport" with what ur namespace you have created. Let me know if u still face problem

Thank

I simply copied and pasted your text into two files and hit the ASPX page.
(This copy/paste preserved the namespace declarations in the .CS file, so
I'm not sure what else to change.)
