Hi Jan,

You need to place a breakpoint inside of the btnUpdate_Click method and check the dsOrders DataSet just after the line

Dim dsOrders As DataSet = CType(Session("OrderDataSet"), DataSet)

Make sure the DataAdapter property is populated with an actual DataAdapter object.

You might also want to create a new Session object and just put a string in it. Save it in the Page_Load, just like the saving of the DataSet is done. Then in the btnUpdate_Click method try to retrieve the string. I really think your problem is that your machine is not configured to use Sessions.
