You want to handle the ItemDataBound event for dataRepeater.

In the event handler check e.Item.ItemType and when it is Header you can
do a e.Item.FindCont rol("testLink") to get a reference to the
LinkButton. From there change what you need.

Hope this helps

RE: LinkButton in Repeater control

Hi Peter,

As other member suggested, you can register the "ItemCreate d" event of
Repeater control and then use "FindContro l" to locate the linkbutton. Here
is a complete example (with aspx and codebehind) which demonstrate this:

============asp x =============== ==
<form id="form1" runat="server">
<div>

<asp:Repeater id="dataRepeate r" runat="server"
onitemcreated=" dataRepeater_It emCreated">
<HeaderTemplate >
Header data
<table class="repeat_t able">
<tr id="rowHeadLine ">
<td id="fieldHeadLi ne">
<asp:LinkButt on
ID="testLink"
runat="server"

Text="hit me">
</asp:LinkButton>
</td>
</tr>
</HeaderTemplate>
<ItemTemplate >
<tr>
<td><hr />item</td>
</tr>
</ItemTemplate>
<FooterTemplate >
</table>
</FooterTemplate>

</asp:Repeater>

</div>
</form>

==============c ode behind========= ====
public partial class RepeaterPage : System.Web.UI.P age
{
protected void Page_Load(objec t sender, EventArgs e)
{
if (!IsPostBack)
{
string[] items = new string[] { "aaa", "bbb", "ccc", "ddd" };

dataRepeater.Da taSource = items;
dataRepeater.Da taBind();
}
}
protected void dataRepeater_It emCreated(objec t sender,
RepeaterItemEve ntArgs e)
{
if (e.Item.ItemTyp e == ListItemType.He ader)
{
LinkButton lbtn = e.Item.FindCont rol("testLink") as LinkButton;

if (lbtn != null)
{
lbtn.CommandNam e = "Display"; lbtn.CommandArg ument =
"argument";
lbtn.Click += delegate
{
Response.Write( "<br/>LinkButton clicked");
};

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

Hope this helps.

Sincerely,

Steven Cheng
