Modify the Save_Position method to return a bool value: true for OK, false for "an error occured"
Then check in your code:

C#

objt.Position_Number = TxtPositionNum.Text;
objt.Grade = Txtgrade.Text;
objt.StartDate = TxtStartDate.Text;
 
if (objt.Save_Position())
    {
    Business_Logic.Employee obje = new Business_Logic.Employee(); 
    obje.Position_Number = TxtPositionNum.Text;
    obje.Cell_Number = TxtCellNumber.Text;
    obje.Email = TxtEmail.Text;
    
    obje.Save_Employee();
    }

Alternatively, throw an exception in your Save_Position method, and catch it in the code which calls your fragment. It can then report a problem to the user.

Solution 1

Use the flag variable to check whether error is occurred or not. If there no error then save the code otherwise ignore it.
