execute code on subform without adding a record

[markjkubicki]

I have a subform with a couple command buttons in the form footer. One of the controls is a toggle button that simply changes the backcolor of the form's detail section (as way for the user to remind themselves that the information in the detail entries may need some addtional work / editing / entries / etc.)
The problem is that when there are no entries in the detail section, clicking the contol, adds an entry. Although the entry is blank, it is unnecessary, and causes problems later on.
Is there a line of code that I can add to allow the procedure to execute without adding the blank entry to the subform's data source?

Const NormalColor As Long = -2147483643
Const FlagColor As Long = 9434879



Private Sub tglInstallationNoteFlag_Click()
If Me.tglInstallationNoteFlag = False Then
Me.Detail.BackColor = NormalColor
Else
Me.Detail.BackColor = FlagColor
End If
End Sub

thanks in advance,
mark

You can disable the toggle button when there is no record. Try this by putting the code in the "on current" event of your form.

Dim sKey As Integer
sKey = Nz(Me.YourPrimaryKeyField, 0) 'assuming it is a number field. If it is text, change the declearation for sKey to "string"
If sKey <> 0 Then
Me.tglInstallationNoteFlag.Enabled = True
Else
Me.tglInstallationNoteFlag.Enabled = False
End If

Let's assume that the main record is for a widget as part of a larger order that is being put together, the subform would then contain, if necessary, a list of accesories for that widget... The the sales person may want to flag to himself (by clicking this toggle control and changing the subforms detail back color) that thef have not yet entered the accessories...

In this case, I would want the control to be active although there are currently no records

(...hope thi help clarifios where I am going?)

in Form_BeforeUpdate, you could DoCmd.CancelEvent if you want to check the form entries there. Or use me.Undo. You need to look at the event sequence to see where your error checking and intervention is needed.

In your case, the reason the radio control creates a new record is because your control is bound to the table containing the sales items. Even though there is no record when you go to the sales items' sub form, when you click to enable the radio control button, you actually create a new sales item record. To get around that, you can put the check control field in the main record (sales) and have the radio control field in the main form. Code it so that if it is checked, the color changes in your sub form

adding me.undo in front of my code (at the control's click event) worked perfectly...
thanks
