protected void ButtonView_Click(object sender, EventArgs e)

{

string Fullurl = "newpage.aspx/";

OpenNewBrowserWindow(Fullurl, this);

}


//This is used to open new browser window

public static void OpenNewBrowserWindow(string Url, Control control)

{

ScriptManager.RegisterStartupScript(control, control.GetType(), "Open", "window.open('" + Url + "');", true);

}
