Casting DynamicClass from OpenAccessLinqDataSource

[Chris]

Hello, using RadComboBox I want to add some attributes from the OpenAccessLinqDataSource that populates it on the DataBound event. The DataItem looks good but I can't figure out what to cast the DynamicClass to! Doh.

ASPX DataSource

<telerik:OpenAccessLinqDataSource ID="OAL_Stock_Topic" runat="server"
    ContextTypeName="Flow.Financials_ST2" EntityTypeName=""
    ResourceSetName="Stock_topics" Select="new (ID, Market, IsIndex, IsHolidayClosed)"
    Where="Enabled == @Enabled">
    <WhereParameters>
        <asp:Parameter DefaultValue="1" Name="Enabled" Type="Int16" />
    </WhereParameters>
</telerik:OpenAccessLinqDataSource>

c# for DataBound Event

protected void MarketItemDataBound(object o, RadComboBoxItemEventArgs e)
{
    // Does this work? No :(
    Stock_topic st = e.Item.DataItem as Stock_topic;

    // Silly guesses
    var st2 = e.Item.DataItem as Flow.Financials_ST2;
    var st3 = e.Item.DataItem as OpenAccessLinqDataSource;

    // the goal
    e.Item.Attributes["IsIndex"] = "Index Here";
    e.Item.Attributes["IsHolidayClosed"] = "Closed Status Here";
}

Hi Chris,

I have prepared a sample application which demonstrates two different approaches in order to achieve the desired goal.

Approach 1 is using a reflection to find the property and set a new value to it.

Approach 2 is using a view which represents the entity projection.

Hope that helps. If any other questions arise, do not hesitate to contact us back.

Thank you so much. I went with reflection and it worked great! The sample project was very helpful.
