Good day,

At this time rows and columns in the grid are bound to their headers, and the only way you can add new rows and columns is to add headers to the RowHeaders and ColumnHeaders collections. At least you can hide the headers by setting the row headers' width or column headers' height to 0:

// Initialize grid
Grid grid = flowChart.LaneGrid;
grid.AllowResizeHeaders = false;

// Add 1 column, but do not show a header
grid.ColumnHeaders.Add(new Header());
grid.ColumnHeaders[0].Height = 0;

// Add 5 rows, but do not show their headers
for (int i = 0; i < 5; i++)
{
	grid.RowHeaders.Add(new Header());
	grid.RowHeaders[i].Width = 0;
}

flowChart.EnableLanes = true;
 

Tomorrow we will upload an updated help file with more information on the lanes grid. I guess in the next build we can implement a simpler method to create a grid without headers.
