If statement in repeaters ItemTemplate

Question

I'm using an ASP.NET Repeater to display the contents of a <table>. It looks something like this:

<table cellpadding="0" cellspacing="0">
    <asp:Repeater ID="checkboxList" runat="server" OnItemDataBound="OnCheckboxListItemBound">
        <ItemTemplate>
            <tr id="itemRow" runat="server">
                <td>
                    Some data
                </td>
            </tr>
        </ItemTemplate>
    </asp:Repeater>
</table>

It works fine, but i'd like to have an if() statement inside the ItemTemplate so i can conditionally determine if i want to print out a <tr> tag.

So i'd like to have something like this:

<table cellpadding="0" cellspacing="0">
    <asp:Repeater ID="checkboxList" runat="server" OnItemDataBound="OnCheckboxListItemBound">
        <ItemTemplate>

            <% if ( (CurrentItemCount % 2) == 0 ) { %?>
            <tr id="itemRow" runat="server">
            <% } %>
                <td>
                    Some data
                </td>
            <% if ( (CurrentItemCount % 2) == 0 ) { %?>
            </tr>
            <% } %>
        </ItemTemplate>
    </asp:Repeater>
</table>

Is there some way i can achieve this?

PS. The CurrentItemCount is just made up. I also need a way to get the current item count inside that if() statement. But i only seem to be able to get it from <%# Container.ItemIndex; %>, which can't be used with an if() statement?

Answer 1

I would use codebehind:

protected void OnCheckboxListItemBound(Object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
        HtmlTableRow itemRow = (HtmlTableRow) e.Item.FindControl("itemRow");
        itemRow.Visible = e.Item.ItemIndex % 2 == 0;
    }
}
