Show validation messages on formview pageindex changing event

I am updating the current record on the pageindexchanging event on my formview if the page is valid.  If it is not valid I would like it to show the validation control messages where data is not valid; like how it works when you click the Update button.  I'm not sure what command I need to use to do this.  My current code is attached.
Protected Sub fvProjects2_PageIndexChanging(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.FormViewPageEventArgs) Handles fvProjects2.PageIndexChanging

        Page.Validate()


        If Page.IsValid Then
            fvProjects2.UpdateItem(True)
        Else


        End If




    End Sub

       If Page.IsValid Then
            fvProjects2.UpdateItem(True)
        Else
           lblMessage.Visible = True
            lblMessage.Text = "data is not valid."
            lblMessage.ForeColor = System.Drawing.Color.Red
        End If

Then you create the label on the input form.

That's how I would do it but there are folks here who may have better ideas.

This would be the label on input

<FORM...

<asp:Label ID="lblMessage" runat="server" Text="Result:" Visible="false"></asp:Label>
</FORM>
Sorry I forgot it

I already have multiple validation controls in my form.  How do I get it to only make visible  the validation controls where the control value that it validates is invalid?  Here is my edititemtemplate.

<EditItemTemplate>
        
            <table cellpadding="0" width="900" cellspacing="0" border="0">
            <tr valign="top">

                <td width="60%" align="center"><PagerSettings FirstPageText="First" LastPageText="Last" Mode="NextPreviousFirstLast"
            NextPageText="Next" PageButtonCount="100" PreviousPageText="Previous" /></td>
                 <td width="20%" align="right">  
                 <div style="width:115px;">
                <div class="linkbutton-l"><asp:LinkButton ID="LinkButton2" runat="server" CausesValidation="True" CommandName="Update"

                <div class="linkbutton-r"> 
                <asp:LinkButton ID="LinkButton3" runat="server" CausesValidation="False" CommandName="Cancel"
