Emanon -

I know this is a bit late, but I have written quite a few ASP.NET AJAX 4.0 (DataView, Sys.Observer, and Binding) posts on my blog:

The Client Templates post (DataView) contains code of the DataView and a WCF service while the Data Binding post contains code that uses the DataView and ADO.NET Data Services.

AJAX DataView Template: Bind to li element

Emanon — Tue, 27 Jan 2009 16:18:28 GMT

I'm working with the ASP.Net 4.0 Preview 3 build. I've been unsuccessful in my attempts to bind the value of 'PrefValue' (returned by the HTTP response) to the 'li' element. I'm not getting any errors and the data that I'm looking for is getting returned, but I can't get it to bind to the 'li' element. I'm hoping that someone can review my code and see what I need to change.

HTML

<body xmlns:sys="javascript:Sys"
    xmlns:dataview="javascript:Sys.UI.DataView"
    sys:activate="*">
    <h1>Title</h1>
    <div id="">
        <ul id="" class="sys-template" sys:attach="dataview"
        dataview:datasource="{{ new Sys.Data.AdoNetDataSource() }}"
        dataview:serviceuri="Service.svc"
        dataview:query="GetWidgetPrefValue">
            <li>{{ PrefValue }}</li>
        </ul>
    </div>
</body>

Service.svc

<WebGet()> <OperationContract()> _
    Public Function GetWidgetPrefValue() As DataSet
        Dim WidgetID As Int16 = 9
        Dim CorpID As String = "emanon"
        Dim PrefID As Int16 = 2
        Dim ds As New DataSet
        Dim dt As New DataTable
        Dim da As New DSTableAdapters.PrefsMyWidgetsTableAdapter
        dt = da.GetWidgetPrefValue(WidgetID, CorpID, PrefID)
        ds.Tables.Add(dt)
        If Not ds.Tables(0).Rows.Count = 0 Then
            Return ds
        End If
        Return Nothing
    End Function
