I am new to .NET and looking at the tablestyles for a datagrid, it would seem that you could define multiple tablestyles, say one that shows 3 columns and one that shows 2 columns, then based on some criteria the grid would display one way or the other. But I cannot find how you would set the style you currently want to use (at designtime or runtime). Maybe I miss the use for multiple tablestyles, what other uses would there be?
