在 asp.net 中启用或禁用 div

你好，有谁知道如何启用和禁用Hole div内容。我有一个 div，它有一个 celendar 和文本框以及下拉列表等......我希望当用户按下按钮时，div 内的内容被禁用，请注意，我不想让它们不可见，而是启用或禁用. 现在我知道我可以单独禁用每个文本框日历等。但是我想知道是否有一种方法可以使Hole div内容禁用，从而节省一些行代码和时间。感谢这里是 div 内容的代码：

 <asp:Calendar ID="mtcDataMR" runat="server" onselectionchanged ="mtcDataMR_SelectionChanged" ></asp:Calendar>
       <br />
      &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
      <asp:TextBox ID="txtData" runat="server" ReadOnly="True"></asp:TextBox>
      <br />
     </fieldset>
     <fieldset>
          <legend>Filtrar Marcações</legend>
          <br />
          Nome de Utente<br />
     <asp:CheckBox ID="chkFiltroUtente" text=" " runat="server" AutoPostBack="true" OnCheckedChanged="chkFiltroUtente_CheckedChanged" /><asp:TextBox ID="txtFiltrarNomeUtente" runat="server" AutoPostBack="true" OnTextChanged="txtFiltrarNomeUtente_TextChanged" ReadOnly="True" ></asp:TextBox>
          <br />
          <br />
      <fieldset>
           <legend>Tipo de Marcações a Mostrar</legend>
              <asp:RadioButton ID="rdbConsultas" text="Consultas" runat="server" GroupName="rdb" AutoPostBack="true" OnCheckedChanged="rdbTratamentos_CheckedChanged" />
              <asp:RadioButton ID="rdbTratamentos" text="Tratamentos" runat="server" GroupName="rdb" Autopostback ="true" Checked="True" />
      </fieldset>
         <br />
         Nome de Especialista<br />
          <asp:CheckBox ID="chkFiltroEspecialista" Text=" " runat="server" /> <asp:DropDownList runat="server" ID="cbxFiltroEspecialista" OnSelectedIndexChanged ="cbxFiltroEspecialista_SelectedIndexChanged" AutoPostBack="true" /> <br />
         Local de Tratamento<br />
          <asp:CheckBox ID="chkFiltroLocal" Text=" " runat="server" /> <asp:DropDownList runat="server" ID="cbxLocal" OnSelectedIndexChanged ="cbxFiltroLocal_SelectedIndexChanged" AutoPostBack="true" /> <br />
         Hora de Inicio<br />
          <asp:CheckBox ID="chkFiltroHora" Text=" " runat="server" /> <asp:DropDownList runat="server" ID="cbxFiltroHora" OnSelectedIndexChanged ="cbxFiltroHora_SelectedIndexChanged" AutoPostBack="true" /> <br />
         <fieldset>
             <legend> Estados a Apresentar</legend>
             <asp:CheckBox ID="chkMRSuspensas" runat="server" text="Mostrar Marcações Suspensas" AutoPostBack ="true" OnCheckedChanged="chkMRSuspensas_CheckedChanged"></asp:CheckBox>
             <br />
             <asp:CheckBox ID="chkMRCanceladas" runat="server" text="Mostrar Marcações Canceladas" AutoPostBack="true" OnCheckedChanged="chkMRSuspensas_CheckedChanged"></asp:CheckBox>
         </fieldset>
         <asp:Button text="Limpar Filtros" ID="btnFiltroClear" runat="server" OnClick="btnFiltroClear_Click"  />
      </fieldset>

  </div>

顺便说一句，我目前使用的是（点击按钮）

 mtcDataMR.Enabled = False
        txtData.Enabled = False
        chkFiltroUtente.Enabled = False
        rdbConsultas.Enabled = False
        rdbTratamentos.Enabled = False
        chkFiltroEspecialista.Enabled = False
        chkFiltroLocal.Enabled = False
        chkFiltroHora.Enabled = False
        chkMRSuspensas.Enabled = False
        chkMRCanceladas.Enabled = False
        btnFiltroClear.Enabled = False
        cbxFiltroEspecialista.Enabled = False
        cbxLocal.Enabled = False
        cbxFiltroHora.Enabled = False

但是正如您所看到的，代码行太多了。
