body: <p><br>
  I have a repeater in my asp.net webform. In "ItemTemplate" of the repater i added a asp:button. And i write the following code on "OnClientClick" event of the button.<br></p>
  
  <pre><code>//This is javascript function
  function DeleteGroup(groupID){
  return confirm('Do you want to delete ' + groupID);
  
  //This is asp.net page code&lt;br&gt;
  &lt;asp:Button runat="server" ID="btnDelete" Text="Delete"
  OnClientClick="
  return DeleteGroup(&lt;%# DataBinder.Eval(Container.DataItem, "GrupID") %&gt;); 
  " /&gt;
  </code></pre>
