Generate popup from Code behind

If we need to Generate Popup box from Code behind –

Page.RegisterStartupScript(“AlertWindow”, “<script language=javascript>alert(‘Please select atleast one Value.’)</script>”);

If the popup Page is using Ajax i.e. ScriptManager ,UpdatePanel Then

ScriptManager.RegisterClientScriptBlock(this.Page, GetType(), “AlertWindow”, “alert(‘Please select atleast one Value.’)”, true);
