We will need a DataGrid control.

Liking the library so far - just some feedback that at this time, this is the only thing stopping me from attempting to move forward with it.

Do you have any recommendations or suggestions on alternatives that might be reasonably compatible in the meantime?

Found that there is no DataGrid or DataGridView. As such I have to stop trying update my Winform app to use Modern.Forms.
