title: how to raise inner repeater itemcommand event
body: <p>Here is what my current logic looks like</p>
  
  <pre><code>&lt;asp:repeater&gt;
  
      &lt;asp:button id="btnMain"/&gt;
  
    &lt;asp:repeater&gt;
       &lt;asp:button id="btnChild"/&gt;
    &lt;/asp:repeater&gt;
  
  &lt;/asp:repeater&gt;
  </code></pre>
  
  <p>On click of "btnchild", I need to open up user control in overlay to do some of kind of verification and once user provide the information, I need to further process the "btnChild" command.  </p>
  
  <p>The logic is kind of pausing the itemcommand event and require some user verification and move forward with the itemcommand on user verification.</p>
  
  <p>So how can i raise repeater's itemcommand event on submitting overlay data? </p>
