How to Set Individual Row IsReadOnly Property Based on Cell Value in C1DataGrid

To set the IsReadOnly property only for individual cells that contain a specific value in a specific column, you can specifically utilize the BeginningEdit event of the C1.WPF.Datagrid class. This is shown in the sample code below, where a grid contains a column where each cell either contains the values "Active" or "Inactive". If the cell value in the row is "Inactive", then the row should be editable: 

private void Grid_BeginningEdit(object sender, C1.WPF.DataGrid.DataGridBeginningEditEventArgs e)
{
    if (e.Column.Name == "IsReadOnly")
    {
        if ((e.Row.DataItem as Company).IsReadOnly == "Inactive")
        {
            e.Cancel = true;
        }
    }
}
