title: Using Javascript control with Checkbox in a ListView
body: <p>Hi there is a way to use a control Javascript that erase "qtaTextBox" and "costoTextBox"  when I check "selezionatoCheckBox"?
  My problem is the management of the elements in the listview, without it I would be able to do
  Thanks</p>
  
  <pre><code>&lt;ItemTemplate&gt;
          &lt;tr style="background-color: #E0FFFF;color: #333333;"&gt;
              &lt;td&gt;&lt;asp:Label ID="idLabel" runat="server" Text='&lt;%# Eval("id") %&gt;' /&gt;&lt;/td&gt;
              &lt;td&gt;&lt;asp:Label ID="attivitaLabel" runat="server" Text='&lt;%# Eval("attivita") %&gt;' /&gt;&lt;/td&gt;
              &lt;td&gt;&lt;asp:Label ID="tariffa_studioLabel" runat="server" Text='&lt;%# Eval("tariffa_studio") %&gt;' /&gt;&lt;/td&gt;
              &lt;td&gt;&lt;asp:Label ID="noteLabel" runat="server" Text='&lt;%# Eval("note") %&gt;' /&gt;&lt;/td&gt;
              &lt;td&gt;&lt;asp:Label ID="dirittiLabel" runat="server" Text='&lt;%# Eval("diritti") %&gt;' /&gt;&lt;/td&gt;
              &lt;td&gt;&lt;asp:Label ID="costo_realeLabel" runat="server" Text='&lt;%# Eval("costo_reale") %&gt;' /&gt;&lt;/td&gt;             
              &lt;td&gt;&lt;asp:CheckBox ID="selezionatoCheck" runat="server" Text="Presente" /&gt;&lt;/td&gt;
              &lt;td&gt;&lt;asp:TextBox ID="qtaTextBox" runat="server" /&gt;&lt;/td&gt;
              &lt;td&gt;&lt;asp:TextBox ID="costoTextBox" runat="server" /&gt;&lt;/td&gt;
          &lt;/tr&gt;
      &lt;/ItemTemplate&gt;
