AfterUpdate Issue

I have a form which contains a combo box.  When the user selects a record from the combobox, an afterupdate event takes place to autopopulate 29 fields on the form.  But it seems to NOT populate fields if a field value is empty.  Or at least I think that is the problem.  Up to the point of the empty field all is ok, but after that point, not fields seem to populate.  Here is the code for the after update event.  Can someone tell me what I'm doing wrong?

    Me.txtCustomer_1 = Me.txtPart_No.Column(1)
    Me.txtPatterns_On = Me.txtPart_No.Column(2)
    Me.txtPattern_Type = Me.txtPart_No.Column(3)
    Me.txtFlask_Size = Me.txtPart_No.Column(4)
    Me.txtPatt_Loc = Me.txtPart_No.Column(5)
    Me.txtCBs = Me.txtPart_No.Column(8)
    Me.txtCPC = Me.txtPart_No.Column(9)
    Me.txtMetal = Me.txtPart_No.Column(10)
    Me.txtHeatTreat = Me.txtPart_No.Column(11)
    Me.txtPaint = Me.txtPart_No.Column(12)
    Me.txtWeight_Cstg = Me.txtPart_No.Column(13)
    Me.WghtEst = Me.txtPart_No.Column(14)
    Me.txtWeight_Mold = Me.txtPart_No.Column(15)
    Me.txtSI = Me.txtPart_No.Column(16)
    Me.txtRemarks = Me.txtPart_No.Column(17)
    Me.txtRemarks_2 = Me.txtPart_No.Column(18)
    Me.txtBrinell = Me.txtPart_No.Column(19)
    Me.txtCert = Me.txtPart_No.Column(20)
    Me.txtPriceRem = Me.txtPart_No.Column(21)
    Me.txtQualityRem = Me.txtPart_No.Column(22)
    Me.chkbxBlanketOrd = Me.txtPart_No.Column(23)
    Me.txtMachining = Me.txtPart_No.Column(24)
    Me.txtChillNcombined = Me.txtPart_No.Column(25)
    Me.txtRev = Me.txtPart_No.Column(26)
    Me.chkbxInclSC = Me.txtPart_No.Column(27)
    Me.chkbxSerialize = Me.txtPart_No.Column(28)
    Me.txtOPother = Me.txtPart_No.Column(29)
    Me.txtCores_Type = getLevels(Me.txtPart_No.Value)
    Me.txtCB_Loc = getLocations(Me.txtPart_No.Value)

Also, something to consider, if the controls that are effected by the combo box are not to be edited by the user, you could try setting their control source to the appropriate column of the combo box.


Go to the properties sheet for the text box "txtCustomer_1" and in the control source, put the follolwing


Alternatively, you could try using the "On Change" event for the combo box.  The After Update event is occurring when you exit the combo box to another control or when you save the record.  Their are other events in between that could be causing the problem, however, without seeing the db, this is just speculation.
why are you calling a combo box txtPart_no?

I had mis-named it way back when it was developed.  I should have named it cboPart_No.  But does the name matter?

No, but it sure throws troubleshooting for a loop.
BTW, you are aware that the column index is 0 based? ie.  the first value of the column array is column(0)?
SteveL13Author Commented:
Yes.  But column (0) is actually the Part no which does not need to be populated to any field because that is the key being selected from the combobox.
What is the record source for the combo?
SteveL13Author Commented:
It is tblPartsMasters
Sorry, should have asked before if you can upload the db.
