推荐答案

您可以在JavaScript中使用focus()方法.
这是示例代码.

You can use the focus() method in JavaScript.
Here is a sample code.

<script type="text/javascript">
   function setFocus()
    {
        var checkbox = document.getElementById('<%=checkBox1.ClientID %>');
        var Textbox =  document.getElementById('<%= txtTest.ClientID%>');
        if(checkbox.checked)
        {
          Textbox.disabled =false;
          Textbox.focus();
        }
        else
        {
            Textbox.disabled =true;
        }
    }
    </script>

<asp:CheckBox ID="checkBox1" runat="server" OnCheckedChanged="checkBox1_CheckedChanged"  />
  <asp:TextBox ID="txtTest" runat="server" Enabled="false"></asp:TextBox>

在文件后面的代码中，将此行包含在Page_Load()
下

In your code behind file include this line under Page_Load()

checkBox1.Attributes.Add("onClick", "setFocus()");
