I'm getting this error: DataBinding: 'System.Char' does not contain a property with the name 'Title'.

Code:

It occurs when the Repeater try's to databind.  I have a property (column) named title in the Review table (???)



	Code:
	   Using myDataContext As New TreatReviewDataContext()

           
            Dim allReviews = From review In myDataContext.Reviews _
            Order By review.Title _
                       Select New With {review.Title}

            Repeater1.DataSource = allReviews
            Repeater1.DataBind()


        End Using
    End Sub


</asp:GridView>
        <asp:Repeater ID="Repeater1" runat="server">
        <ItemTemplate><h3>
            <asp:Literal ID="Literal1" runat="server" Text='<%#Eval("Title")%>'></asp:Literal>
        
        </h3>
        <asp:BulletedList ID="lstReviews" runat="server" DataSource='<%#("Reviews")%>' DataTextField="Title">
        </asp:BulletedList>
        </ItemTemplate>
        </asp:Repeater>

The problem is in the DataTextField; if I remove it - no errors. My understanding is that the data text field refers to the column I want shown? That was a valid column name.

Take a look at the LINQ query:

Select New With {review.Title}

You're only selecting the Title, not the Reviews collection used for BulletedList control.
