Closing Browser Window C#

i think you need to handle using client side scripts.

In the onclick event of your button in the .aspx code I think you just need to add window.close()

Something like this...

<asp:button onclick="window.close();" />

I don't have the ability to test this but I'm pretty sure it should work.

This should work:
<input type="button" value="Close Window" onclick="window.close()">

Yes, that might be what I meant -- like I said, I couldn't test it as I don't have .Net compiler handy :(

Response.Write("<script>window.close()</script>");
should also do.

Its was also there in the link i provided before.

btnClosef.Attributes("onclick") = "javascript:return closeform()"

and in ur javascript

function closeform()
{
window.close();
return false;
}

Note:

If you add the attribute in the code behind, this should be done in the Page_Load event so that it's there the first time you click the button, not in the Click event of the button.
