Hello,

I am using the following Repeater control. How do I reference the label
"lblCurrentYr"?

Thanks, sck10


<asp:Repeater id="rptCustomerRevenue" runat="server">
<HeaderTemplate>
<table class="tblOutline" style="width:100%" border="1px">
<tr>
<th style="width:37%;">Service</th>
<th style="width:12%;"><asp:Label ID="lblCurrentYr" runat="server"
/></th>
<th style="width:11%;"><asp:Label ID="lblYearMinus01" runat="server"
/></th>
<th style="width:15%;"><asp:Label ID="lblYearMinus02" runat="server"
/></th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td style="width:37%; text-align:left;"><%#Eval("Service")%></td>
<td style="width:12%; text-align:right;"><%#Eval("CurrentYrMinus00",
"{0:C0}")%></td>
<td style="width:11%; text-align:right;"><%#Eval("CurrentYrMinus01",
"{0:C0}")%></td>
<td style="width:15%; text-align:right;"><%#Eval("CurrentYrMinus02",
"{0:C0}")%></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
 
Handle ItemCreated or ItemDataBound event. Use e.Item.ItemType to tell the
Header item. Use e.Item.FindControl("lblCurrentYr") to locate the label
inside the header item.
 
Hello Steve,

For your scenario, there are two possible means:

1. Directly access the repeater header through controls collection by
index(this is not quite recommended since index is not guranteed to work
between different version). e.g.

#header row is the first childcontrol in repeater's Controls collection
====================
protected void Button1_Click(object sender, EventArgs e)
{
Label lbl = Repeater1.Controls[0].FindControl("lblCurrentYr") as
Label;

if (lbl != null)
{
lbl.Text = "new text " + DateTime.Now.Ticks;
}



}
=========================

2. As Eliyahu has mentioned, one place we can access repeater's header(or
footer)'s controls is the ItemCreated, you can get the label in header in
that event and store it into a page variable so that you can use it later.
e.g.

========in page code behind=========
public partial class Part1_repeaterpage : System.Web.UI.Page
{
Label _repeaterLabel = null;
................


protected void Button1_Click(object sender, EventArgs e)
{

Response.Write("<br/>label value: " + _repeaterLabel.Text);

}


protected void Repeater1_ItemCreated(object sender,
RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Header)
{
Label lbl = e.Item.FindControl("lblCurrentYr") as Label;

if (lbl != null)
{
_repeaterLabel = lbl;
}
}
}
.....................
}

=============================

Hope this helps.

Sincerely,
