Hello all,

I am building a simple app using the asp:datagrid control.

The problem I have is that my source datatable contains a four column primary key. The dataset is strongly typed and my schema reflects the compound key's existence.

Any idea how i set the datagrid's datakeyfield to represent this compound key. The app works fine except for the update (in other words it dont work fine). I am sure this is the problem.

Thanks in advance.
