Devexpress RowUpdating ve RowValidating

Question

Merhaba;

Rowupdating ve rowvalidating eventlerini birlikte aşağıdaki gibi kullanma istiyorum fakat aşağıdaki haliyle textbox boş ve dolu olarak kaydedemiyorum.Yalnızca textbox için;

if(!gorkisi.isvalid) 

                

{ errLab.Visible = true;

                errLab.Text = "Please correct this value";
              }
else {updat command....

}

olacak şekilde kodu güncellediğimde Belirtilen Yöntem Desteklenmiyor hatası alıyorum.

Konu ile ilgili yardımcı olur musunuz?Teşekkürler
