#23 DataGrid row height same for all rows

When setting row height (or using Rows.AutoSize) for DataGrid (maybe it's even for all VirtaulGrids) all rows would be same size as last set row heigth. So after calling Rows.AutoSize all rows are in height measured for last row. I tried to find a reason for it but couldn't on my own. Any hint would be really appreciated as it's quite urgent for me. I will post fix once I find it. Thank's in advance.

You are right but this is by design. On some kind of virtual grid you have a single Row instance so a single row height. For now this is how the datagrid work.

But anyway it's a bug as VirtaulGrid is not usable if it contains multiline data. Maybe you have any ideas how to change it so that each row would have it's own instance? I really need it so I can devote my time to it but I need a hint from you where to start. Thanks!

Here a possible solution (thanks to ornus):

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;
}
