Examples

The following example edits the value of one column in the last row of a DataGrid control. The example uses the BeginEdit, EndEdit, methods to edit the column's value and commit the change to the row.

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
