objectdatasource

could anyone please give me some pointers on how to use the objectdatasource with nettiers an vs2005. I've created an asp.net project, generated nettiers code, and when I drop a combobox on the page an use the gui tools to connect to objsource I select to use tablename.sqlclient.getall and everything looks fine. But when I run it - it says "no parameterless constructor" etc... any ideas on how this is supposed to be setup?

if you want to wire up a dropdownlist though you should try using the new EntityDropDownList with a strongly typed data source as these are a piece of cake to wire up...

<data:EntityDropDownList runat="server" ID="dataProductID" DataSourceID="ProductIDProductsDataSource" DataTextField="ProductName" DataValueField="ProductID" SelectedValue='<%# Bind("ProductID") %>' AppendNullItem="true" Required="true" NullItemText="< Please Choose ...>" ErrorText="Required" />

<data:ProductsDataSource ID="ProductIDProductsDataSource" runat="server" SelectMethod="GetAll"  />

You can find them both in the WebLibrary.
