亲爱的禁用文本框，以便没有人可以访问文本框

Dear disable the textbox so that nobody can access textbox

您好，

我认为您应该将textboxt设置为只读模式....
如果您使用的是ajax工具包，那么...

参见以下示例代码:

Hi,

I think you should set your textboxt to read only mode....
If you are using ajax toolkit then...

See this sample code:

<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %>

<td align="left">
   Admission Date:
</td>
<td align="left">
  <asp:textbox id="txtAdmissionDate" runat="server" maxlength="10" readonly="true"> 
   </asp:textbox>
  <cc1:calendarextender popupbuttonid="imgDatepicker" id="CalendarExtender1" targetcontrolid="txtAdmissionDate"   runat="server" filtermode="ValidChars" filtertype="Custom" validchars="1234567890/">
  </cc1:calendarextender>
  <asp:imagebutton runat="Server" id="imgDatepicker" imageurl="~/Calendar.png" />
