No default member found for type 'GridInsertionObject'

I am using a user control as my edit form for my data grid.  Everything was going great until I had to populate my dropdown lists on the user control with the data when in edit mode on the datagrid.  Once I figured out how to populate the dropdowns in edit mode by using this code:

Protected

Sub grdProject_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles grdProject.ItemDataBound
    If (TypeOf e.Item Is GridEditableItem AndAlso CType(e.Item, GridEditableItem).IsInEditMode) Then
        Dim editedItem As GridEditableItem = CType(e.Item, GridEditableItem)
        Dim UserControl As UserControl = CType(e.Item.FindControl(GridEditFormItem.EditFormUserControlID), UserControl)
        CType(UserControl.FindControl("dlstClassification"), DropDownList).SelectedValue = e.Item.DataItem("PROJECT_CLASSIFICATION")
        CType(UserControl.FindControl("dlstRating"), DropDownList).SelectedValue = e.Item.DataItem("PROJECT_RATING_ID")
        CType(UserControl.FindControl("dlstProjectStatus"), DropDownList).SelectedValue = e.Item.DataItem("PROJECT_STATUS")
        If Not e.Item.DataItem("PROJECT_ASSIGN_ID") Is System.DBNull.Value Then
            CType(UserControl.FindControl("dlstProjectAssignID"), DropDownList).SelectedValue = e.Item.DataItem("PROJECT_ASSIGN_ID")
        End If
        CType(UserControl.FindControl("dtReqCompDate"), Telerik.Web.UI.RadDatePicker).SelectedDate = e.Item.DataItem("PROJECT_REQ_COMP_DATE")
    End If
End Sub

My insert function stopped working correctly.  I started getting an error in the code above stating "No default member found for the type 'GridInsertionObject'.  Can anyone help me figure out what the issue is.

After reviewing some more form posts, I was able to add in the GridEditFormInsertItem into my ItemDataBound sub so that it would bring up my insert form without any issues.  To do that, I changed:

If (TypeOf e.Item Is GridEditableItem AndAlso CType(e.Item, GridEditableItem).IsInEditMode) Then

End Sub

to:

If

(TypeOf e.Item Is GridEditFormInsertItem) Then
ElseIf (TypeOf e.Item Is GridEditableItem AndAlso CType(e.Item, GridEditableItem).IsInEditMode) Then

End Sub
