>As i seen that you are binding datatable or DataView to listbox1.
The question title and the id of the datasource explicitely says its an OBJECTDATASOURCE not a datatable or dataview. But yes set the DataTextField and DataValueField properties appropriately.

>ah yeah, the OS is bound to a function in the DAL, that returns a DataSet.
Why not bind the dataset directly to list then?

If you manually create listitem then its ok.
Like
listboxl.Items.Add(new ListItem("text1","value"))
But here you bind datatable or dataset that's why you have to provide that information.

Can you please give me column name that return from objectdatasource.

I repeat my question:
If DAL is returing you a dataset, you could bind to this dataset directly without using an objectdatasource in between. Is there any reason for not taking this approach?
