Question

DataGrid is binded to some DataTable.
User changed some values. I want to mark changed row with some color.
I’ve done it. But how to notify DataGrid, that current row values have been changed?

P.S. I use trigger on currentRow.Row.RowState for indicating changed row. I don’t want to refresh ALL ItemsSource – it operation is too long.

Not the best decision but it works as I expect:

dataView.ListChanged += (o, e) =>
{
    if (e.ListChangedType == ListChangedType.ItemChanged)
    {
        DataRowView row = ((DataView)o)[e.NewIndex];
        if(row != null)
        {
            MethodInfo method = typeof(DataRowView).GetMethod("RaisePropertyChangedEvent", BindingFlags.Instance | BindingFlags.NonPublic);
            method.Invoke(row, new object[] { "Row" });
        }
    }
};
