将条件从组合框传递到Access 2010中的另一个组合框

Question

I am trying restrict the records in combo box 2 (cboNames) based on the selection of combo box 1 (cboClass).

Combo box 1 and combo box 2 are both based on records in the same table, tblNames.

Combo box 1's row source is set too

SELECT [tblNames].[ChildID], [tblNames].[Class] FROM tblNames;

Combo box 2's row source is set too:

SELECT tblNames.ChildID, tblNames.[Full Name], tblNames.Class FROM tblNames WHERE (((tblNames.Class)=[Forms]![frmInsertNewRecord]![cboClass]));

I was under the impression this should work but it obviously inst. Combo box 2 is blank.

Can anybody identify what i am doing wrong?

Answer 1

Once the value of the first combo box changes, you need to refresh the recordset of the second one.

You need to either hit the refresh button ( F5 ) or add the following code in the _AfterUpdate event of the 1st box:

Private Sub cboClass_AfterUpdate() 
    Me.cboName.Requery
End Sub
