setting individual row heights in data grid

[Jurg Hinderling]

I have read and successfully tried the reflection based methodology to set the row heights in a data grid. However, when one uses a class derived from DataGrid reflection can't get to the private objects in the base class anymore as inheritance only propagates non-private items and hence property "DataGridRows" or method "get_DataGridRows" is not accessible through reflection anymore from the derived class. Has anyone seen a method that works even in a derived class?

Getting and setting row heights is actually quite easy and will work for base and derived classesm no need to use reflection:

Get: the rowheight of a grid row can always be determined from the GetCellBounds(row,col).Height property.

Set: raise MouseDown and MouseUp events with MouseEventArgs set to same values as if one manually resized a column by clicking in the row resize area. Works perfectly.

Gee, I am talking to myself :-)

of course the approach I described without using reflection works only for derived classes as OnMouseUp and OnMouseDown are protected DatatGrid methods. Sorry for the confusion.

I have the same porblem with the derived grid class. if your method does not require to use reflection and "get_DatagridRows" method. wonderful.

Could you send me little code snippet. if you have. I did not quite understand the set : thing.

thanks

I have used following code in autoresize method instead of relfection, but it does not seem to work.

Dim i As Integer
While i < numRows
'get the current height of he pearicular cell.
size = g.MeasureString(dgEdit(i, 1).ToString(), dgEdit.Font, 400, sf)
Dim h As Integer = Convert.ToInt32(size.Height)
h = h + 10
Dim cellRect As Rectangle
cellRect = dgEdit.GetCellBounds(i, 1)
cellRect.Height = h
i += 1

End While

thanks. any idea.
