My question when i click button the following code does show error . The resource cannot be found. , Requested URL: /Visitors/Admin/frmAdminHome.aspx

Code is as follow

    {
ScriptManager.RegisterStartupScript(this, this.GetType(), "alert", "alert('Alert worked succesfully');window.location ='~/Admin/frmAdminHome.aspx';", true);
}

Error as it gives in browser. The resource cannot be found. , Requested URL: /Visitors/Admin/frmAdminHome.aspx

Answer 1

Try window.location ='../Admin/frmAdminHome.aspx' or window.location ='./Admin/frmAdminHome.aspx' . I assume the actual link for your Admin area is not under current path.
