Link FormView to GridView

[shapper]

Hello,

I have the following GridView:

Private Sub gvTags_Init(ByVal sender As Object, ByVal e As
EventArgs) Handles gvTags.Init
With gvTags
.CssClass = "GridView"
.DataKeyNames = New String() {"TagId"}
.DataSource = ldsTags
.ID = "gvTags"
End With
End Sub ' gvTags_Init

How can I link it to a FormView so when I edit or insert a record
using the FormView when I click the Edit or Insert buttons in the
GridView?

Thanks,
Miguel
