在文本中使用<>作为asp：DropDownList选项

Question

I have the following in my .aspx file:

    <asp:DropDownList ID="title" Width="350px" runat="server">
        <asp:ListItem Value="0">Please Select</asp:ListItem>
        <asp:ListItem Value="Dr">Dr</asp:ListItem>
        <asp:ListItem Value="Mr">Mr</asp:ListItem>
        <asp:ListItem Value="Ms">Ms</asp:ListItem>
        <asp:ListItem Value="Miss">Miss</asp:ListItem>
        <asp:ListItem Value="Mrs">Mrs</asp:ListItem>
    </asp:DropDownList>

I would like to put < > around "Please Select":

<asp:ListItem Value="0"><Please Select></asp:ListItem>

However, the file thinks I am opening a new tag when I use them.

Any ideas on how I can use these, possibly escaping them etc.,?

Answer 1

There's a Text attribute you can use for the text instead of putting the text between the opening and closing tags:

<asp:ListItem Value="0" Text="<Please Select>" />

You can also use the HTML entities if you prefer:

<asp:ListItem Value="0" Text="&lt;Please Select&gt;" />

Answer 2

You can use HttpServerUtility.HtmlEncode function

String TestString = "This is a <Test String>.";
String EncodedString = Server.HtmlEncode(TestString);
