[AccessD] trying to filter a form on a control's value

I guess I am missing the point of the question and not understanding what
you are trying to do.

You've got to set the filter.  It can be a generic control reference in the
filter string, but your still going to need to do something in the
AfterUpdate of a control to force the form to apply the filter even so.

But that is not any better than using the UDF Jim (well, a tiny bit less
overhead and a bit more direct). However, when the control changes there
will be no change to what the filter evaluates to when the control changes
value. And that is my goal.

 You were close....correct syntax is:

 Me.Filter = "[FKCompanyID] = " & [Forms]!frmOrders![txtWholesalerID]

  if this is frmOrders, then that can be shortened to:

 Me.Filter = "[FKCompanyID] = " & Me.[txtWholesalerID]

 This assumes a numeric.  If ID is text, then:

 Me.Filter = "[FKCompanyID] = " & chr$(34) &
[Forms]!frmOrders![txtWholesalerID] & chr$(34)

Subject: [AccessD] trying to filter a form on a control's value

I want to filter a form, when a toggle is depressed based on a control value
on my form. When that control changes, I want the filter to be applied. I
have tried without success to set the filter a myriad of different ways, and
whatever I try, the filter is ineffective (returns no records) when I use
any of these attempts.

I have tried:
         Filter = "FKCompanyID= [Forms]!frmOrders![txtWholesalerID]"
         Filter = "FKCompanyID= [Forms]!frmOrders!txtWholesalerID"
         Filter = "FKCompanyID=
[Forms]!frmOrders!Controls("txtWholesalerID")
         Filter = "FKCompanyID= [Forms]!frmOrders!cboWholesaler.Column(0)
         Filter = "FKWholesalerID=
Forms(""frmOrders"").Controls(""cboWholesaler"").Column(0)"
         Filter = "FKWholesalerID=
Forms(""frmOrders"").Controls(""txtWholesalerID"")"

Finally, getting desperate, I tried a UDF GetWholesalerID() which returned
the value of one of the controls above, and that would work in the filter.

         Filter = "FKWholesalerID=" & GetWholesaler()

The annoyance though, is that I need to call this in the AfterUpdate event
of the control that drives it, since the function is not volatile - as
reference to a control would be on its own.

Is there any form of compliant syntax which will allow me to establish a
direct dependence between the filter and the referenced control?
