Hi there,

I found something out with comparing the Jump Start with the MM Northwind Sample App:

If I change 'this.dsOrders = this.oOrder.GetOrdersByCustomerID(this.pckCustomer.Text);' to 'this.oOrder.GetOrdersByCustomerID(this.pckCustomer.Text);' (remove the 'this.dsOrders = ') it works without error message.

Any further advice?

TIA, Ralph
