I have a vTree with 1 From Date column & 1 To Date column. Before commiting to database I check that FromDate <= ToDate for each row. Is there a way to mark a cell that has an error (i.e. FromDate > ToDate) like the MS DataViewGrid SetError method?

For example when I click the save button I do this:
If vt.FindRow(dtrw).Item(procDx.Name).ToString.Trim.Length = 0 Then
Dim cellData As New CellData(procDx)
binding.GetCellData(vt.FindRow(dtrw), procDx, cellData) 'get the default binding for the given row and use it to populate the cell data
cellData.Error = "Dx pointer Error"
vt.UpdateRowData(vt.FindRow(dtrw))
cellErr = True
End If

Where dtrw if the current datarow I'm checking in a For/Next loop, vt is the vTree. After vtUpdateRowData I see no red dot in the errored cell.

Yes you can associate errors either with a particular cell or the whole row. If you binding to DataSet then you can just call DataRow.SetColumnError to set the error that should be displayed for a particular column, or set the DataRow.RowError property to set an error in the row header. This will display an error icon in the column or row header and when the user hovers over the error icon the error is displayed in a tooltip. The sample Data Set Browser project demonstrates doing this if you enter a Required Date for an order to be more than 1 month later than todays date it will set an error on the Required Date cell.

If you are not binding to a DataSet then you can still display errors but you need to handle them programmatically. To do this handle the GetCellData event and set the error programmatically eg
