    I was hoping this project would help me understand how to programmatically configure an OpenAccessDataSource on Selecting. But Selecting is not handled. Is there and example I could use somewhere else. Would be more useful if it has the latest ORM release for .Net 4.0 and VS 2010. But just need to understand some concepts. i use to be able to use something like this with a LinqDataSource:

    e.result = from x in dbContext.Orders where == _id select x;

    I was expecting something similar with OpenAccessDataSource - but no luck so far.

    Hello Bruno,

    Firstly I want to thank you for the valuable input.
    You should use the OpenAccessDataSource.CommandText property which enables you to specify a custom OQL query. But in this case you will not be able to perform create, delete and update operations through the control.
    What you should do is to provide an event handler for the OpenAccessDataSource.Selecting event and specify the OQL statement there:

    <telerik:OpenAccessDataSource ID="OpenAccessDataSource1" runat="server"
    ObjectContextProvider="WebApplication.NorthwindContext, WebApplication"
    EnableDelete="false" EnableInsert="false" EnableUpdate="false" />

    protected void Page_Init(object sender, EventArgs e)
        this.OpenAccessDataSource1.Selecting += new EventHandler<Telerik.OpenAccess.OpenAccessDataSourceSelectingEventArgs>(OpenAccessDataSource1_Selecting);
    protected void OpenAccessDataSource1_Selecting(object sender, Telerik.OpenAccess.OpenAccessDataSourceSelectingEventArgs e)
        this.OpenAccessDataSource1.CommandText = string.Format("select o from OrderExtent as o where == {0}", _id);

    Hope that helps.

    All the best,
