After googling and reading tons of pages I can't find the solution to the following challenge. I need to close current tab (in the C# code of a page). The best solution I found is the following:

 Response.Write("<script language='javascript'> { window.close(); }</script>");

The only issue is that the Browser asks "The web page you are viewing is trying to close the tab. Do you want to close the tab." I would like to find a way to NOT show this message but simply close the tab. Is it possible? If you know, how?

UPDATE: Found solution:

Response.Write("<script language='javascript'> { window.open(window.location,'_self').close(); }</script>");
