private void AcceptOrReject(DataRow row)
{
// Use a function to validate the row's values.
// If the function returns true, end the edit;
// otherwise cancel it.
if(ValidateRow(row))
row.EndEdit();
else
row.CancelEdit();
}
private bool ValidateRow(DataRow thisRow)
{
bool isValid = true;
// Insert code to validate the row values.
// Set the isValid variable.
return isValid;
}
Private Sub AcceptOrReject(ByVal row As DataRow)
' Use a function to validate the row's values.
' If the function returns true, end the edit;
' otherwise cancel it.
If ValidateRow(row) Then
row.EndEdit()
Else
row.CancelEdit()
End If
End Sub
Private Function ValidateRow(ByVal row As DataRow) As Boolean
Dim isValid As Boolean
' Insert code to validate the row values.
' Set the isValid variable.
ValidateRow = isValid
End Function
