Can't set CHECKBOX to be a required field

[KeithGanzenmuller]

I'm having trouble setting several checkboxes to "required".
In Studio when I open my form the checkbox "required" property is grayed out.
The checkbox is False be default and I want to require the user to confirm they have checked a serial number before saving the form data.
It is a text field in the GDB and has a coded value domain that only allows True or False values.

Thanks
Keith

Hi Keith,

This behavior has been included by design as of ArcPad 7.

The CHECKBOX Control does not support the required attribute because of the nature of the control (eg. can only be true/false, not null)

The need for further clarification about the CheckBox Control behavior in the Customizing ArcPad Help has been noted by the ArcPad Dev Team and should be included in future versions of ArcPad and the new Customizing ArcPad Online Help. 

Thanks,

Hannah

Keith,

You can force user to check the checkbox(es)  by using form/page validation.
For example, on page 1 of your form, you have a checkbox control named "Check1".  This code below will help you get started:

Have this subroutine somewhere in your VBScript:

Sub ValidateChk(pThisEvent)
 Dim pControls
   Dim pThisForm, pThisPage
  
   Set pThisPage = pThisEvent.Object
   Set pThisForm = pThisPage.Parent
   Set pControls = pThisForm.Pages("PAGE1").Controls

 If pControls.Item("Check1").Value = False Then
  ThisEvent.MessageText ="Checkbox is required."
  ThisEvent.Result = False
  Exit Sub
 End If
End Sub

Then, under Page 1, OnValidate Event, call the subroutine above:

Call ValidateChk(ThisEvent)

Excellent, thanks for the code. That will do the trick.
