Question

I have a form with a combo box & a checkbox (chkClosed). For the combo box I have put the row source as a select query. It has two fields (both from Table1): Field1, Field2 (not shown) & its criteria is [Forms]!Form1]![chkClosed]

Table1 example data:

Field1    Field2
Test      -1
Test1      0
Test2      0
Test3     -1

Problem is that when I uncheck chkClosed at runtime the dropdown list doesn’t change. I know its evaluating it correctly though as if I switch to design then back to form view while its checked it shows Test & Test3 in dropdown list & vice versa. Just time it evaluates it is at startup rather than constantly, I am sure I will have to change something with events. This is just an example, the data I am doing is actually from a SQL source, but the logic still applies I just use criteria: IIf([Forms]![Form1]![chkClosed]=-1,1,0)

Answer 1

You need to requery the combo box to update the row source. In the checkbox’s AfterUpdate event, add the following line:

Private Sub chkClosed_AfterUpdate()
    Me.Combo1.Requery
End Sub
