flowchart resizing

Hi stoyo.

I've a problem about FlowChart resizing.

I explane.

I insert a gridLine in flowchart:

Grid grid = flowchart.LaneGrid;

The grid is initially composed of one ColumnsHeader and five RowHeaders. The total height of RowHeaders is greater than flowchart' height, but VScrollBar is not visible. VScrollBar is visible only when i draw a box. i want that the VScrollBar is visible at the begin of the program.
Is possible?
I try to insert a box at the right-bottom corner of flowchart. In this way i obtained my objective, but i'd like to use a flowchart property.

Is my explain clear?

Tanks

You have to modify the document rectangle so that it contains the entire lane grid. The following code should do this:

Code
Select All
Grid grid = flowChart.LaneGrid;

RectangleF columnHeaderBounds = grid.GetColumnHeaderBounds();
RectangleF rowHeaderBounds = grid.GetRowHeaderBounds();
RectangleF gridBounds = RectangleF.Union(columnHeaderBounds, RowHeaderBounds);

flowChart.DocExtents = new RectangleF(
    0,
    0,
    grid.LeftMargin + gridBounds.Width,
    grid.TopMargin + gridBounds.Height);

Regards,
Meppy
