Skipping Items During Data Binding

Question

Greetings!

I have a Repeater control that's using an XmlDataSource control.

<asp:FormView id="myFormView" runat="server" DataSourceID="myXmlDataSource">
    <ItemTemplate>
            <span>Items</span>
        <asp:Repeater id="myRepeater1" runat="server" DataSource='<%# XPathSelect("Items/*")%>'>
            <HeaderTemplate>
                <ul>
            </HeaderTemplate>
            <ItemTemplate>
                <li><%# XPath("text()")%></li>
            </ItemTemplate>
            <FooterTemplate>
                </ul>            
            </FooterTemplate>
        </asp:Repeater>
        <span>Things</span>
        <asp:Repeater id="myRepeater2" runat="server" DataSource='<%# XPathSelect("Things/*")%>'>
            <HeaderTemplate>
                <ul>
            </HeaderTemplate>
            <ItemTemplate>
                <li><%# XPath("text()")%></li>
            </ItemTemplate>
            <FooterTemplate>
                </ul>            
            </FooterTemplate>
        </asp:Repeater>
    </ItemTemplate>
</asp:FormView>        
<asp:XmlDataSource ID="myXmlDataSource" XPath="Root" EnableCaching="false" runat="server" />

The XML looks something like this:

<Root>
    <Items>
        <Item>A</Item>
        <Item>B</Item>
        <Item>C</Item>
        <Item>D</Item>
    </Items>
    <Things>
        <Thing>1</Thing>
        <Thing>2</Thing>
        <Thing>3</Thing>
    </Things>
</Root>

In some cases, I'd like to "skip" the "B" item when binding so that it isn't displayed. Is there a way during the DataBinding event that I could skip the binding of the "B" item so that it won't be displayed?

You could investigate the current DataItem in the OnItemDataBound() method of the repeater and skip processing that item if it matches your criteria
