I am using vb 2005 linked from ms access 2003 and i am using binding navigator
Thnks expects i want a example and a tutorial about queris general.

i must write these in the form code sure?
Right click on the product combo box, click properties, click events tab, click on got focus, from drop down click event procedure.
The vb code will appear and you can paste the above into it.
Make sure Private Sub cboProductID_GotFocus() & End Sub are not duplicated

i have a combox and 2-3 textboxes that moved from combobox is these the problem?
the relation you create has to bind fields with the same values. Your Products table surely have a SupplierID column. This is the field you need to relate:
NicolaouDBDataSet.Relation s.Add("rel suppliersp roducts", _
NicolaouDBDataSet.Tables(" suppliers" ).Columns( "supplierI D"), _
NicolaouDBDataSet.Tables(" Products") .Columns(" supplierID "))
NicolaouDBDataSet.Relation
NicolaouDBDataSet.Tables("
NicolaouDBDataSet.Tables("
ASKER
A relation already exists for these child columns.
a relation in the database or in the dataset? it has to exist in the dataset. if it exist, just provide appropriate names to the binding of the combobox and it will work.
ASKER
can i uploadi it here to help me fix it
You have a fully working example. You should be able to do it. If you replace the name of the fields and relations, it just works. If you upload it, I won't be able to test it as I don't have the matching database!

emoreau when the combobox select for example Royal&rothmans to see the details of the products and the company that belong to it?????
ok apparently you got it working so I won't need to upload anything.
Using the technique I have used here (to set the DisplayMember on the relation), the order is ALWAYS from the parent to child (Suppliers to Products in your case).
If you need to modify that, you will need to use solution #2 from my article. Handle the SelectedIndexChanged event of the product combo to fill the supplier combo.

That i ask can u explain me?
That i ask can u explain me?
I never bind controls like you do.
in the SelectedIndexChanged of the supplier combo, fill the textbox you need. it currently does not follow because you manually feed the combo. Otherwise, you would need to synchronize the binding source but, as I said, I never bind controls like you do.

In order to help, can I ask you to make yourself clear. Without clear indication I am losing my time.

ASKER
give me an example code how to fill a combox with 2-3 textboxes please
I don't understand why you want that. You have already have that.
I have also provided this code which does exactly what that:
If Me.ProductIDComboBox.Selec tedIndex <> -1 Then
Dim dr As DataRow = Me.NicolaouDBDataSet.Produ cts.Rows.F ind(Me.Pro ductIDComb oBox.Selec tedValue)
If dr IsNot Nothing Then
'Me.DescriptionTextBox.Tex t = dr.Item(0).ToString
Me.DescriptionTextBox.Text = dr.Item("ProductName").ToS tring
Me.UnitPriceTextBox.Text = dr.Item("UnitPrice").ToStr ing
Me.QuantityTextBox.Text = dr.Item("QtyPerUnit").ToSt ring
End If
End If
Finally, I can tell that whatever I provide you won't be good! It seems that everything I have provided is not. I never spend so much time on a single question.

Yea can u explain me why the suplierid combobox and the textboxes is working the relation between the Supplieridcombobox and the product id combobox is working fantastic BUT the textboxes that belong to Product id is not changed even i have add this code you give ABOVE
can u understand me ?
can u understand me ?
ASKER
to Product id combobox is not changed even i have add this code you give ABOVE
you cannot bind the textboxes to the dataset. you would need to bind them to the relations. beleive me it is a lot easier to manually feed them (like the code just pasted).
>>to Product id combobox is not changed even i have add this code you give ABOVE
In the last code you sent me, the SelectedIndexChanged event was not handled. I have already provided that code.

ASKER
oups ok sorry how to to bind them to the relations what you mean with that.Itry it manually with the code you give me before but is not work the textboxes belong to product id combobox
you don't want to bind manually, you would have the same problem.
you better assign the values manually in the SelectedIndexChange event.
