    Please find the below options for validation, may be these would help.

     

    Options 1:

     

    if (Condition satisfied)

    {

     //Code for Update Logic

    }

    Else

    {

      throw new Exception("The Date format is not correct format");

    }

     

    Option 2:

     

    string sMessage;

    sMessage = " The Date format is not correct format ";

    str = "<script language=javascript> var strTrueFalse; ";

    str = str + " alert('" + sMessage + "');";

    str = str + "</script>";

    Page.RegisterStartupScript("ppname", str);

     

    Option 3:

     

    In App_Code you can write common function that would be used in project.

     

    public static void DisplayUserMessage(int nMessageTypeID)

        {

            string strScript = string.Empty;

            strScript = "<script type='text/javascript'>alert('";

            if (nMessageTypeID == 1)

            {

                strScript = strScript + Resources.Multilingual.Recordhasbeensavedsuccessfully;

               

            }

            else if (nMessageTypeID == 2)

            {

                strScript = strScript + Resources.Multilingual.Recordhasbeenupdatedsuccessfully;

            }

            else if (nMessageTypeID == 3)

            {

                strScript = strScript + Resources.Multilingual.Recordshasbeendeletedsuccessfully;

            }

            else if (nMessageTypeID == 4)

            {

                strScript = strScript + Resources.Multilingual.Recordshasbeeninactivateddeletedsuccessfully;

            }

          

            strScript = strScript + "');</script>";

            System.Web.UI.Page P = (System.Web.UI.Page)System.Web.HttpContext.Current.Handler;

            ScriptManager.RegisterStartupScript(P, typeof(System.Web.UI.Page), "alertScript", strScript, false);

        }

     

    In application you can use like that

     

    if (Condition satisfied)

    {

     //Code for Update Logic

    }

    Else

    {

      PMAP_Common_Methods.DisplayUserMessage(2);

    }
