Event AfterFieldChanged Sample Project

CASE

The attached project is configured with four fields, a Validation form, and a script that demonstrates two uses of the AfterFieldChanged event:

1. For a given Text field, display the number of characters entered in the field
2. For a given CheckBox field, display a string ("checked" or "unchecked") that represents the state of the CheckBox

COMPONENTS

This example uses the following fields:

• TextField — Input field into which you type the characters you want counted.
• TextFieldLength — Output field that displays the number of characters in TextField.
• Checkbox — CheckBox field.
• CheckboxState — Output field that displays the state of Checkbox, checked or unchecked.

VALIDATION FORM

The field "Checkbox" is formatted as a CheckBox on the Validation Form.

SCRIPT

The script example included in the project performs the usage described above:

Private Sub ValidationForm_AfterFieldChanged(ByVal pXDoc As CASCADELib.CscXDocument, ByVal pField As CASCADELib.CscXDocField)
   Dim iLength As Integer
   Select Case pField.Name
      Case "TextField"
         iLength = Len(pField.Text)
         pXDoc.Fields.ItemByName("TextFieldLength").Text = CStr(iLength)
      Case "Checkbox"
         If pField.Text = "1" Then
            pXDoc.Fields.ItemByName("CheckboxState").Text = "checked"
         Else
            pXDoc.Fields.ItemByName("CheckboxState").Text = "unchecked"
         End If
   End Select
End Sub
