I'm not very familiar with source control outside of local repository since the uploading code to the internets is prohibited by the company. .I leave that up to you. \r\n\r\n\"did not think anyone would use any of my stuff ever :)\"\r\nI've seen plenty of people looking for a 2D grid and yours is the closest that still conforms to the MVVM practice. The solutions I found don't use the datagrid, requires black magic, or put code in xaml's code behind. We don't do code behind unless we are making a custom control. \r\n\r\nAlso, there is also a need for a horizontally oriented datagrid and I think your work will be easy to extend to implement a `ColumnSource` since you already have the `RowsSource`.
