#1 ControlColumn ControlFactory directions

[Keith McCreery]

Hello,

I am in need of help implementing ControlFactory for a Control Column.

I have created a ControlFactory that will create a TextBox, ListBox or CheckBox based on the cell.Data.

However, I need the following assistance...

1) When the ControlColumn is resized, what is the best method to resize the controls in the column? I tried overriding the UpdateControl method and (a) recreating the control and also (b) changing the properties (size) on the control, but the painting of the control flickers with the old control. It seems the old control in (a) is not disposed or (b) something I can't explain.
1.1) Who is responsible for disposing the ols control when using UpdateControl()? From what I read, I assumed Table or TableModel would handle the disposing.
1.2) In general, when a property of the Table, TableModel, ColumnModel, Row, or Cell changes, what is the best method to update a control in a ControlColumn that I create?

2) If I have the Table, TableModel, Row or ColumnModel, and know the Cell position, how can I get to the Control that the ControlFactory created?
2.1) Or, is functionality limited (or best left) to UpdateControl?

3) Is there a better way to get the current cell width and height, other than...
int height = cell.Row.Height;
int width = cell.Row.TableModel.Table.ColumnModel.Columns[ cell.Index ].Width;

4) I have not tried yet, but I assume, that I will need to attached my own GotFocus, LostFocus, Changed events to Controls created by ControlFactory (I'm 99% sure, but double-checking).
4.1) If I do, during the event, I get the sender (which is the control), I would use Table.GetContainingCell( control ) to access the container Cell, correct?

Thanks,
Keith McCreery
