not marked as serializable

I'm using UltraWebGrid v8.1.20081.1000 with IdeaBlade 3.6.2.2.  I am simply trying to bind a list the the grid.  I've tried...

EntityList<SPSProviderSearch> el = pm.GetEntities<SPSProviderSearch>(q, QueryStrategy.DataSourceOnly);
uwgProviders.DataSource = el;
uwgProviders.DataBind();
With Error: Type 'System.Data.DataColumn' in Assembly 'System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.

I’ve also tried…
BindableList<SPSProviderSearch> bel = new BindableList<SPSProviderSearch>();
foreach (SPSProviderSearch ps in el)
            bel.Add(ps);
uwgProviders.DataSource = bel;
uwgProviders.DataBind();
With Error: Type 'System.Data.DataColumn' in Assembly 'System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' is not marked as serializable.

I can make it work if I create a wrapper object, load it and bind.

This does not work the same as the Winforms version of infragistics.  What am I doing wrong?

    It is very hard to tell from what I am seeing, but I do have a couple of suggestions that may help us go further

    1. Bind stock asp:gridview and asp:datagrid components to the same datasource and see if it works

    2. Is see that what you are binding to, "el", is returned from GetEntities method - is it possible that it contains a list of tables? In this case, you may beed to set the DataMember property of the control as well

    3. If 1 & 2 do not help, could you please paste the complete stack trace you are getting (not just the last line) - this will surely provide additional clues.

    Hope this helps!
