im trying a lot with your datagrid but dont find a solution for changing the backgroundcolor of cells, which are part of one specific column. F.e. they should change to green if process is completed else they should be red. The values of the columns get loaded by database. Datagrid already takes cellstyle and the cellstyle should only affect background property to the cells in the specific column. Hope you can help me further and my project is in MVVM style.
