What is the best way to close a browser window of an AJAX ASP.NET application after the server-side has been executed.

I found this solution, but it seems a little plex for what I want to acplish. Or is this the best way to acplish my task.

UPDATE: I have to close the window after the button is pressed

UPDATE 1: I tried the solution from the other SO question, and it did not work for me.

<asp:Button ID="btnMyButton" runat="server" onClick="btnMyButton_Click" />

protected void btnMyButton_Click(object sender, EventArgs e)
{
}

---

I used the following code in my page, but the "The webpage you are viewing is trying to close the windows" module window pops up.

if (ScriptManager.GetCurrent(this).IsInAsyncPostBack)
            ScriptManager.RegisterStartupScript(upApproveRequest, typeof(string), "closeWindow", "window.close();", true);

Any way to prevent this?

• @Gortok - I came up a solution to sets the OnClientClick event with the JavaScript function of the button that closes the child window when it is opened from the parent page. – Michael Kniskern Commented Jul 23, 2009 at 21:02

Actually you can do this by placing the following code in your button click event.

protected void btnMyButton_Click(object sender, ImageClickEventArgs e)
{
    // Update database
    bool success = Presenter.DoDatabaseStuff();

    if (success)
    {
        // Close window after success
        const string javaScript = "<script language=javascript>window.top.close();</script>";
        if (!ClientScript.IsStartupScriptRegistered("CloseMyWindow"))
        {
            ClientScript.RegisterStartupScript(GetType(),"CloseMyWindow", javaScript);
        }
    }
    else
    {
        // Display failure result
        result_msg_area.Visible = true;
        lblError.Text = "An error occurred!";                
    }
}

No, there is no way to close a browser window without the user's consent. You can log them out of their application, but you can't forcibly close the browser window.

To avoid the script warning, you can use this:

window.open('', '_self', '');window.close();

So:

if (ScriptManager.GetCurrent(this).IsInAsyncPostBack)
        ScriptManager.RegisterStartupScript(upApproveRequest, typeof(string), "closeWindow", "window.open('', '_self', '');window.close();", true);

That's pretty much it. You can just use ScriptManager.RegisterStartupScript(...)
