title: How can I assign an ID to a checkbox in a Repeater?
body: <p>I have these checkbox on a Repeater:</p>
  
  <pre><code>&lt;asp:Repeater id="repeaterCategories" runat="server"&gt;
      &lt;ItemTemplate&gt;
          ...
  
          &lt;asp:CheckBox ID="chbCategoria" Text="My Label" runat="server" /&gt;
  
          ...
      &lt;/ItemTemplate&gt;
  &lt;/asp:Repeater&gt;
  </code></pre>
  
  <p>every checkbox must coincide with a Page ID taken from Database (every repeaterCategories Item has its unique id, so that one).</p>
  
  <p>How can I set it? So, at the postback, I check which CheckBox Controls are Checked and I get the IDs.</p>
