In this article I will explain with an example, how to find and access Repeater controls with HeaderTemplate and FooterTemplate in ASP.Net using C# and VB.Net.
 
 

HTML Markup

The following HTML Markup consists of:
Repeater – For displaying data.
The Repeater consists of following Templates:
HeaderTemplate – The HeaderTemplate consist of a Label control.
ItemTemplate – The ItemTemplate consists of Eval function which is used to bind Country data to columns.
FooterTemplate – The FooterTemplate consist of a Label control.
<asp:Repeater ID="rptProducts" runat="server">
    <HeaderTemplate>
        <asp:Label ID="lblHeader" runat="server" Font-Bold="true" /><br />
    </HeaderTemplate>
    <ItemTemplate>
        <%#Eval("Name")%> - <%#Eval("Country")%><br />
    </ItemTemplate>
    <FooterTemplate>
        <asp:Label ID="lblFooter" runat="server" Font-Bold="true" />
    </FooterTemplate>
</asp:Repeater>
 
 

Namespaces

You will need to import the following namespace.
C#
using System.Data;
 
VB.Net
Imports System.Data
 
 

Find and access the ASP.Net Repeater Header and Footer Template

Inside the Page_Load event handler, the Repeater is populated with dummy data using DataTable.
Note: For more details on how to create dynamic DataTable, please refer my article Dynamically create DataTable and bind to GridView in ASP.Net.
 
Then, the Control and Label class objects are created and the HeaderTemplate and FooterTemplate is referenced and Header and Footer are set.
Finally, the message is set in HeaderTemplate and FooterTemplate using Label control.
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        //Binding the Repeater control.
        DataTable  dt =  new DataTable();
        dt.Columns.AddRange(new DataColumn[2] {
                            new DataColumn("Name"),
                            new DataColumn("Country") });
        dt.Rows.Add("John Hammond", "United States");
        dt.Rows.Add("Mudassar Khan", "India");
        dt.Rows.Add("Suzanne Mathews", "France");
        dt.Rows.Add("Robert Schidner", "Russia");
        rptProducts.DataSource = dt;
        rptProducts.DataBind();
 
        //Finding the HeaderTemplate and access its controls
        Control HeaderTemplate = rptProducts.Controls[0];
        Label lblHeader = HeaderTemplate.FindControl("lblHeader") as Label;
        lblHeader.Text = "Customers";
 
        //Finding the FooterTemplate and access its controls
        Control FooterTemplate = rptProducts.Controls[rptProducts.Controls.Count - 1];
        Label lblFooter = FooterTemplate.FindControl("lblFooter") as Label;
        lblFooter.Text = "www.aspsnippets.com";
    }
}
 
VB.Net
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        'Binding the Repeater control.
        Dim dt As DataTable = New DataTable()
        dt.Columns.AddRange(New DataColumn(1) {
                            New DataColumn("Name"),
                            New DataColumn("Country")})
        dt.Rows.Add("John Hammond", "United States")
        dt.Rows.Add("Mudassar Khan", "India")
        dt.Rows.Add("Suzanne Mathews", "France")
        dt.Rows.Add("Robert Schidner", "Russia")
        rptProducts.DataSource = dt
        rptProducts.DataBind()
 
        'Finding the HeaderTemplate and access its controls.
        Dim  HeaderTemplate As Control = rptProducts.Controls(0)
        Dim lblHeader As Label = TryCast(HeaderTemplate.FindControl("lblHeader"), Label)
        lblHeader.Text = "Customers"
 
        'Finding the FooterTemplate and access its controls
        Dim FooterTemplate As Control = rptProducts.Controls(rptProducts.Controls.Count - 1)
        Dim lblFooter As Label = TryCast(FooterTemplate.FindControl("lblFooter"), Label)
        lblFooter.Text = "www.aspsnippets.com"
    End If
End Sub
