Error in DBGrid

The documentation for the DBGrid in VB4's Professional and Enterprise Editions states that the control's Text and Value properties allow you to read or set the contents of a cell. This would seem to indicate that you could use these properties to update a field in a record set to which the grid is bound. Unfortunately, that is not the case. The following code generates runtime error 438: "Object doesn't support this property or method:"
 ' This doesn't work:
DBGrid.Columns(0).Text = "Hello, world."

' Neither does this:
DBGrid.Columns(0).Value = "This is a test"
The workaround is to update the data control's record set directly. The change will be reflected automatically in the bound grid:
 datCtl.Recordset.Edit
datCtl.Recordset.Fields(0) = "This is a test"
datCtl.Recordset.Update
