推荐答案

如果您不希望用户输入任何内容，则只需将ReadOnly属性设置为true.

If you don''t want the user to enter anything, then just set the ReadOnly property to true.

一种做到这一点的方法就是制作这个textbox readonly.

另一种方法是在控件中添加"onkeypress="return false"属性:

One way to do that is making this textbox readonly.

another way to do is to add "onkeypress="return false" attribute in your control:

<asp:TextBox ID="TextBox2" onkeypress="return false" runat="server"></asp:TextBox>

注意:这仅对asp.net有用.如果它是Winform，则使用第一种方法.

NOTE: This is only useful for asp.net. if it is a winform use the first method.

还有另一种方法使文本框变为只读，请参见下文:

There is another way of making textbox readonly, see below:

<asp:textbox id="TextBox2" onfocus="this.blur" runat="server"></asp:textbox>

将onfocus="this.blur"属性添加到您的文本框.希望对您有帮助.

Add onfocus="this.blur" attribute to your textbox. Hope it helps you.
