Solution Summary:

If the web control is in the EditItemTemplate, in the FormView's DataBound event, check that the current mode is "Edit", find the control, and select the option based on the DataItem with the appropriate property.

Solution Details:

The following code checks the current mode, and if it's "Edit" mode, finds the dropdownlist control and selects the option with the value in the DataItem:

    Private Sub fv_Member_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles fv_Member.DataBound
        If fv_Member.CurrentMode = FormViewMode.Edit Then
            Dim drv As DataRowView = fv_Member.DataItem
            Dim ddlTitle As DropDownList = CType(fv_Member.Row.FindControl("DdlTitle"), DropDownList)
            ddlTitle.ClearSelection()
            If Not ddlTitle.Items.FindByValue(drv.Item("Title")) Is Nothing Then
                ddlTitle.Items.FindByValue(drv.Item("Title")).Selected = True
            End If
        End If
    End Sub
