#25 Virtual row height

[Davide Icardi]

it's impossible to set height for a specific virtual row. Rows.SetHeight uses one value for all rows (RowHeight). so, it's pretty much unusable. I wanted to hide certain row when data source is a data table. couldn't. here's a simple code to fix this to work correctly.

replace RowsSimpleBase.GetHeight & SetHeight with this:

private readonly Dictionary< int, int > _heights = new Dictionary< int, int >();

public void ResetHeights()
{
_heights.Clear();
}

public override int GetHeight(int row)
{
if( _heights.ContainsKey( row ))
{
return _heights[ row ];
}
else
{
return RowHeight;
}
}
public override void SetHeight(int row, int height)
{
_heights[ row ] = height;
}

if there's a better way, I'd like to know about it
