سلام دوستان من این برنامه را برای ثبت اطلاعات در یک جدول resid نوشتم که با جدول Bimar از طریق فیلد خارجی FkParvandeId_Bimar ارتباط داره ولی در این قسمت

textBox9.DataBindings.Clear();
textBox9.DataBindings.Add(" Text ", objDataView, " PkParvandeId");

این error را می دهد

Cannot bind to the property ' Text ' on the target control

Parameter name: PropertyName

فاصله قبل و بعد Text رو بردار و همینطور PkParvandId
