Grids are commonly initialized in a form's AfterOpen event. If a grid is unconditionally initialized in a form's AfterOpen event, however, the grid's data will be overwritten whenever a saved session is reopened. Unconditional initialization looks something like this:
Dim dt As New DataTable() ' Add some columns to the DataTable _Grid.Value = dt
To maintain grid data when an existing session is revisited, add a conditional check:
If (_Grid.Value Is Nothing) Then ' do initialization here End If
