Finding LinkButton Control inside of Repeater control!!! Help

I have LinkButtons in which are placed inside of a repeater control. I am trying to be able to retrieve that linkbuttons .text value in a onclick event. 

Here is my HTML code:
            <asp:repeater id="topics" runat="server">
<asp:LinkButton id="TopicLink1"  OnClick="_TopicClick"  runat="server" >
<%# Container.DataItem( "name" ) %><%# Container.DataItem( "number" ) %>

Here is the <script> code I am trying to use to get the control. It compiles correctly, but when I click a LinkButton it does not print out any text.
Sub _TopicClick(sender As Object, e As System.EventArgs)

Dim myLink As LinkButton
mylink = CType(sender,LinkButton)

Dim myLink2 As LinkButton
myLink2 = CType(mylink.parent.FindControl("TopicLink1"), LinkButton)


End Sub

Need help binding data to GridView control inside a Repeater control
Hi, How do I bind data to a GridView control that is inside a Repeater control?Thanks,Sam Looks like I bind the data to the Repeater control then handle binding individual sets of data to GridViews in the Repeater's OnItemDataBound event.

I have a Checkbox control inside of the ReorderList control, <ItemTemplate> area. How would I find the control to determine if that checkbox is checked and get the datakey for it? examples would be great. thanks! This works the same as it does with other repeaters.  If you get a reference to the data item (e.g. the row), you can do a FindControl("Checkbox1") or whatever.
