LaneGrid rowcount

Hi,


I added few blank lanes to a diagram but the LaneGrid.RowHeaders.Count is returning only the number of lanes with atleast one node in it.

Even diagramLite.GetRect() is not considering lanes with out any nodes in it.

Please advice

Thanks

Hi,

How exactly do you add the blank lanes? Keep in mind that LaneGrid.RowHeaders.Count returns the number of the top-level rows only. If you add rows as children to other rows, this property will not reflect the change. However, you can get the number of leaf rows in the grid through LaneGrid.RowCount.

Regards,
Meppy

Hi


I am adding the row header as follows

diagramLite.LaneGrid.RowHeaders.Add(header);

and this is how I am trying to loop through all the rows

for (int i = 0; i < diagramLite.LaneGrid.RowCount; i++)

But after adding few rows, some with nodes and some without, the count returns only the number of rows with nodes.



Thanks

Hi,

I am not able to reproduce this. The rows and columns in the lane grid have no notion of diagram nodes and the returned count should not be affected by this in any way. Is it possible that a swimlane layout has clipped some of the rows as discussed in this thread?

Meppy

Hi,


Please find the attaced sample code. Also included in the solution is a txt file listing the issues.

My requirement was to resize the host diagramlite control to to the effective size of the lanegrid after applying the layout. Since empty lanes are dissappearing, GetRect is not considering the height of those lanes.

Please advice.


Thanks

Hi,

Utilities.GetRect is a convenience method, which returns a rectangle with the current size of the specified element, it doesn't auto-calculate size based on the element's contents. What I would have recommended is actually something that already exists in your sample:

Code
Select All
var rect = diagramLite.LaneGrid.GetColumnHeaderBounds();
rect.Union(diagramLite.LaneGrid.GetRowHeaderBounds());
diagramLite.Bounds = rect;

Isn't this code doing exactly what you need?

Regards,
Meppy
