w3c validation error in asp.net

问题

I am new in W3c validations, I am trying to fix this error but it's not happening. The error is following:

character "&" is the first character of a delimiter but occurred as data.

I am using DataList Control to bind data and here is the line where the w3c validation error occurs.

<asp:Label ID="lblDescription"  
           runat="server" 
           Text='<%#Eval("Decr") %>'>
</asp:Label>

In database, the Decr is stored and this(&) special character is also given in the description field. w3c is not validating this line.

回答1:

& is a special charater for concat, you need to escape it: make them all & not &.

回答2:

Here is the solution I came up with:

<asp:Label ID="lblDescription" runat="server" Text='<%# Server.HtmlEncode( (string) Eval("Decr")) %>'></asp:Label>
