Newbie help please...

I have a grid view within a multiview panel, with View and Delete buttons added in template form.  In the code-behind I capture the Delete button successfully and am able to delete the record successfully, but the databind to refresh the grid brings up the EmptyDataText message unless I refresh the page entirely!  Can anyone give me a pointer??

Thanks!  Marty

Form code looks like this:

<%@ Control Language="vb" Inherits="CCO.Modules.CCOMemberships.ViewCCOMemberships"
    CodeFile="ViewCCOMemberships.ascx.vb" AutoEventWireup="false" Explicit="True" %>
<%@ Register TagPrefix="dnn" TagName="Audit" Src="~/controls/ModuleAuditControl.ascx" %>
<%@ Register TagPrefix="dnn" TagName="Label" Src="~/controls/LabelControl.ascx" %>
<asp:ObjectDataSource ID="MembershipObjectDataSource" runat="server" DataObjectTypeName="CCO.Modules.CCOMemberships.CCOMembershipsInfo"
    DeleteMethod="DeleteMembership" InsertMethod="AddMembership" OldValuesParameterFormatString="original_{0}"
    SelectMethod="GetMemberships" TypeName="CCO.Modules.CCOMemberships.CCOMembershipsController"
    UpdateMethod="UpdateMembership" OnInit="Page_Load">
    <SelectParameters>
        <asp:Parameter DefaultValue="00" Name="ModuleId" Type="Int32" />
        <asp:Parameter DefaultValue="00" Name="ClubID" Type="Int32" />
    </SelectParameters>
</asp:ObjectDataSource>
<center>
    <asp:MultiView ID="MultiView1" runat="server">
        <asp:View ID="ShowMemberships" runat="server">
            <center>
                <dnn:Label ID="lblAddMessage" runat="server" ControlName="lblAddMessage" Suffix=":">
                </dnn:Label>
            </center>
            <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" EmptyDataText="There are no memberships in this Club yet."
                HorizontalAlign="Center">
                <Columns>
                    <asp:TemplateField AccessibleHeaderText="Edit" HeaderText="View" ShowHeader="False">
                        <ItemTemplate>
                            <asp:ImageButton ID="ImageButton2" runat="server" CausesValidation="false" CommandArgument='<%# Eval("MembershipID") %>'
                                CommandName="Edit_Click" ImageUrl="~/images/view.gif" />
                        </ItemTemplate>
                        <ItemStyle HorizontalAlign="Center" />
                    </asp:TemplateField>
                    <asp:TemplateField AccessibleHeaderText="Delete" HeaderText="Delete" ShowHeader="False">
                        <ItemTemplate>
                            <asp:ImageButton ID="ImageButton1" runat="server" CausesValidation="false" CommandArgument='<%# Eval("MembershipID") %>'
                                CommandName="Delete_Click" OnClientClick="return confirm('Are you sure you want to delete this membership?');" ImageUrl="~/images/delete.gif" />
                        </ItemTemplate>
                        <ItemStyle HorizontalAlign="Center" />
                    </asp:TemplateField>
                    <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" ReadOnly="True">
                        <ItemStyle HorizontalAlign="Left" Width="250px" />
                    </asp:BoundField>
                </Columns>
            </asp:GridView>
            <br />
            <center>
                <asp:Button ID="AddButton" runat="server" Text="Add Membership" />
            </center>
        </asp:View>
        <asp:View ID="View1" runat="server">
        </asp:View>
    </asp:MultiView>
</center>

And the code behind looks like this:

Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView1.RowCommand
            If e.CommandName.CompareTo("Edit_Click") = 0 OrElse e.CommandName.CompareTo("Delete_Click") = 0 Then
                If e.CommandName.CompareTo("Delete_Click") = 0 Then
                    Dim congID As Integer = Me.UserInfo.Profile.GetPropertyValue("ClubID")
                    Dim memctl As New CCOMembershipsController
                    memctl.DeleteMembers(ModuleId, e.CommandArgument, Me.UserInfo.Profile.GetPropertyValue("ClubID"), Me.UserId)
                    memctl.DeleteMembership(ModuleId, e.CommandArgument, Me.UserInfo.Profile.GetPropertyValue("ClubID"), Me.UserId)
                    GridView1.DataBind()
                End If
            End If
End Sub

Any ideas??
