C#

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
   {

       try
       {
           switch (e.CommandName)
           {
               case "view":

                   string name = e.CommandArgument.ToString();
                   String js = "window.open('OpenPDF.aspx?id=" + name + "', '_blank');";


                  
                   ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "Welcome", js, true);
                   break;

           }
