First I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,
Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)
But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.
