The events related to validation methods that are of type Single Field Script Validation or Multi-field Script Validation occur during the Server and validation processes. These events can be used to implement a customized validation method. These scripted validation methods can be as all other standard validation methods assigned to a field validation rule.

Remember when using message boxes, they may stop the complete server processing. You can use the property Project.ScriptExecutionMode to distinguish between Serverand validation processing and if multiple instances are configured for Server or Validation the running instance can be retrieved by the property Project.ScriptExecutionInstance.

For a single field and a multi-field script validation method the following events occur:

' Project Script
Private Sub EmptyField_Validate(pValItem As CASCADELib.ICscXDocValidationItem, ErrDescription As String, ValidField As Boolean)

   If Len(pValItem.Text) = 0 Then
      ValidField = True
   Else
      ValidField = False
   End If

End Sub
