Close window on Button click in ASP DOT NET.

To close a browser window there is only one Way i.e to add javascript.

Below are the two methods of making a browser window (page) close.

Method 1 : On page load add the script to the button onclick attribute . It will occur a bit faster.

Method 2 : If User wants to validate some Process before Window close, Its better to use Method 2 ,Because using the first Method no serverside code will get executed.
Here On Button Click Use the Script to close the window.
So Before closing the window we can Validate the Process in the Applications

Codes :

Partial Class Default5

    Inherits System.Web.UI.Page



    'Method 1 : On Page_Load add the Attribute

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        btnClose.Attributes.Add("onclick", "window.close();")

    End Sub



    'Method 2 : on Button Click Use the Script

    Protected Sub btnClose_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnClose.Click

        If Page.IsValid Then

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

        End If

    End Sub

End Class
