Why is AntiXss Library not working with Eval()?

[Solo761]

I am working on a simple ASP.NET application to prove the use of AntiXss library. The library is very powerful and it is working fine with me except with Eval() in aspx pages. For example, if I have a label control like the following:\[code\]<asp:Label runat="server" ID="CommentsLabel" Text='<%# Eval("Name") %>' />\[/code\]How will I be able to use AntiXss with it?I followed this example mentioned HERE, and I added the library to the label control by doing the following:\[code\]<asp:Label runat="server" ID="CommentsLabel" Text='<%#Microsoft.Security.Application.AntiXss.HtmlEncode(((System.Data.DataRowView)Container.DataItem)["Comments"].ToString()) %>'/>\[/code\]And my instructor is still telling me it is vulnerable and I don't know why. Then, instead of using \[code\]AntiXss.HtmlEconde()\[/code\] , I used \[code\]Encoder.HtmlEncode()\[/code\] in the previous line \[code\]<asp:Label runat="server" ID="CommentsLabel" Text='<%#Microsoft.Security.Application.Encoder.HtmlEncode(((System.Data.DataRowView)Container.DataItem)["Comments"].ToString()) %>'/>\[/code\]EDIT:And based on the scanning tool which my instructor is using it, he is still telling me that it is vulnerable. So how to use this library with Eval or Data Binding in general?
