I'd like to resize my chart boxes in a LaneGrid type chart when the cells are re-sized and so have added the following line to the form constructor after InitializeComponent:

           flowChart.LaneGrid.CellBoundsChanged += new CellBoundsEventHandler(LaneGrid_CellBoundsChanged);

Everything works well on a new form: my function, LaneGrid_CellBoundsChanged is called but when I load a chart from disk the event does not seem to be fired when the cells are re-sized - debugging shows that the constructor is called ok and the above line of code is executed.

I'm using version FlowChart .NET version 4.3.1

Any help gratefully received.

Yes, when I load a file, a new form with associated FlowChart and LaneGrid are created and the form's constructor is called (including the line to add the new event handler), but still no events are fired in this case.

Yes, this does seems to make sense.  So I've added a call to add the event handler every time I sucessfully load a file. e.g.

           OpenFileDialog dlg = new OpenFileDialog();

           dlg.DefaultExt = "step";
           dlg.Filter = "STEP files (*.step)|*.step";
           dlg.Title = "Open STEP File";
           dlg.FilterIndex = 0;

           if (dlg.ShowDialog(this) == DialogResult.OK)
           {
                   LoadFromFile(dlg.FileName);
                   flowChart.LaneGrid.CellBoundsChanged += new CellBoundsEventHandler(LaneGrid_CellBoundsChanged);
            }

However, I still have the same problem.  I may be doing something stupid, but I can't spot what it is!  In principle am I doing the right thing?

There should be only one flowChart object in my form - the one created in InitializeComponent - I don't "new" any others.  I've moved the line:

flowChart.LaneGrid.CellBoundsChanged += ....

to my LoadFromFile() function placing it after the call to:

     flowChart.LoadFromStream(stream);

But still no joy.  Any Ideas?

Many thanks: new DLLs work well.  Thanks for excellent support
