c# 2.0 how to append to a repeater control

How do I append to two hyperlink controls within a repeater?

My error:
Error 1 'System.Web.UI.WebControls.Repeater' does not contain a definition for 'items'

--------------------------
<table width="100%" border="0" cellspacing="5" cellpadding="5">
<tr>
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<td>
<asp:HyperLink
ID="HyperLink1"
Runat="server"
Text='<%# Eval("Name") %>'
NavigateUrl='<%# "../Item.aspx?DepartmentID=" + Eval("departmentId") + "&CategoryID=" + Eval("categoryId") + "&ProductID=" + Eval("ProductID")%>'
ImageUrl='<%# "../images/productimages/" + Eval("Image1FileName") %>'
ToolTip='<%# Eval("Name") %>'
CssClass='<%# Eval("ProductID").ToString() == Request.QueryString["ProductID"] ? "ProductSelected" : "ProductUnselected" %>'
>
</asp:HyperLink>
<br />
<asp:HyperLink ID="HyperLinkName" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "Name")%>' NavigateUrl='<%# "../Item.aspx?DepartmentID=" + Eval("departmentId") + "&CategoryID=" + Eval("categoryId") + "&ProductID=" + Eval("ProductID") %>' >
</asp:HyperLink>
<br />
<%# DataBinder.Eval(Container.DataItem, "Price", "{0:c}")%>
<br />
</td>
</ItemTemplate>
<HeaderTemplate>
<strong>
Products</strong>
</HeaderTemplate>
</asp:Repeater>
</tr>
</table>
--------------------------

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string categoryId = Request.QueryString["CategoryID"];
string ep = Request.QueryString["ep"];
if (categoryId != null)
{
Repeater1.DataSource = CatalogAccess.GetAllProductsInCategory(categoryId, ep);
Repeater1.DataBind();
Repeater1.items(0).FindControl("HyperLink1") += "&ep=" + ep; //error
Repeater1.items(0).FindControl("HyperLinkName") += "&ep=" + ep; //error
}
}
}

1st): Repeater1 has a property Items (which is case sensitive)
2nd): FindControl returns a type of Control, so you have tell it what type of control. Here is an example (C#):

HyperLink lnk1 = (HyperLink)Repeater1.Items[0].FindControl("Hyperlink1");
lnk1.NavigateUrl += "&ep=" + ep;

HyperLink lnk2 = (HyperLink)Repeater1.Items[0].FindControl("HyperLinkName");
lnk2.NavigateUrl += "&ep=" + ep;

I am not sure if you are just doing this to Item 0, but if you want it performed on all items, you need to have a Repeater1_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e) event.

I'm trying to do this to all the hyperlink items in the repeater; I'm not sure how to do that.

this?

<asp:Repeater ID="Repeater1" runat="server" OnDataBinding="AppendEP">

protected void AppendEP(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
string ep = Request.QueryString["ep"];

HyperLink lnk1 = (HyperLink)Repeater1.Items[0].FindControl("Hyperlink1");
lnk1.NavigateUrl += "&ep=" + ep;

HyperLink lnk2 = (HyperLink)Repeater1.Items[0].FindControl("HyperLinkName");
lnk2.NavigateUrl += "&ep=" + ep;
}

changed it sort of:

<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
string ep = Request.QueryString["ep"];

HyperLink lnk1 = (HyperLink)Repeater1.Items[0].FindControl("Hyperlink1"); //errors
lnk1.NavigateUrl += "&ep=" + ep;

HyperLink lnk2 = (HyperLink)Repeater1.Items[0].FindControl("HyperLinkName"); //errors
lnk2.NavigateUrl += "&ep=" + ep;
}

error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
