ASP.NET - How do I reference a dynamic control from code behind

I have a button (1 of 2) inside a ListViewItem. The definition is:
<ItemTemplate>
<tr class="ItemStyle" style=" background-color: White ">
<td ondatabinding="ManageButtonText" ID="UserCell" runat="server" align=center Width=180 style="border-bottom: solid 1px #BDF">
<%#Eval("username")%></td>
<td style="padding-left: 6px; padding-right: 3px; border-bottom: solid 1px #BDF">
<asp:Button ID="DetailButton" OnClick="ButtonClick" CausesValidation=false
runat="server" Width=140 Height="22px" Font-Size=8 Text="View/Edit detailed ratings" /> 
<asp:Button ID="SummaryButton" OnClick="ButtonClick" CausesValidation=false
runat="server" Width=140 Height="22px" Font-Size=8 Text="View/Edit summary ratings" />
</td>
</tr>
</ItemTemplate>

The extract in the attached code snippet, from my IE browser's "View Source", shows the ID of my button to be "EmpListView_ctrl0_DetailButton".
But when I try to access the button from code-behind using Page.FindControl("EmpListView_ctrl0_DetailButton"), it returns Nothing.
What am I doing wrong, please?

<table id="EmpListView_Table1" style="margin: 15px; ">
<tr>
<td>
<table id="EmpListView_itemPlaceholderContainer" border="1" cellpadding="4" class="MediumArial " style=" border-collapse: collapse;border-color: #555;
border-style:solid ; border-width:1px; ">
<tr id="EmpListView_Tr2" height="20px" style="font-weight:bold;  background-color: #ddd;">
<th id="EmpListView_Th1" style="border-bottom: solid 1px #333; padding: 5px">Employee Name</th>
<th id="EmpListView_Th2" colspan="2" style="border-bottom: solid 1px #333;">Action</th>
</tr>
<tr class="ItemStyle" style=" background-color: White ">
<td id="EmpListView_ctrl0_UserCell" align="center" width="180" style="border-bottom: solid 1px #BDF">Conradie Eddie</td>
<td style="padding-left: 6px; padding-right: 3px; border-bottom: solid 1px #BDF">
<input type="submit" name="EmpListView$ctrl0$DetailButton" value="View/Edit detailed ratings" id="EmpListView_ctrl0_DetailButton" style="font-size:8pt;height:22px;width:140px;" />&nbsp; 
<input type="submit" name="EmpListView$ctrl0$SummaryButton" value="View/Edit summary ratings" id="EmpListView_ctrl0_SummaryButton" style="font-size:8pt;height:22px;width:140px;" />
</td> 
</tr>
</table>

instead of Page.FindControl("EmpListView_ctrl0_DetailButton") try:

EmpListView.FindControl("DetailButton");

Open in new window

more completely

Button DetailButton = (Button)EmpListView.FindControl("DetailButton");

Thanks for responding
The button(s) I want to access are inside each Listview item. So I have
EmpListView_ctrl0_Detail
EmpListView_ctrl1_Detail
etc
I have the "row" number 0/1/2 etc, now I just need the right syntax to refernce the button
Could you help, please?
