Close a browser window of an ASP.NET and AJAX application

Question

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 complex for what I want to accomplish. Or is this the best way to accomplish 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)
{
}

Answer 1

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

Answer 2

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?

Answer 3

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.

Answer 4

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!";                
    }
}
