if (documentTargetCollection.CanAdd)
{
    if (!documentTargetCollection.Add(new DocumentTarget("CustomerName")))
    {
        throw new InvalidOperationException("The item could not be inserted.");
    }
}
```

textControl.Text = "Customer: Contoso Ltd."
textControl.Select(10, 12)
Dim documentTargetCollection As DocumentTargetCollection = textControl.DocumentTargets
documentTargetCollection.Add(New DocumentTarget("CustomerDetails") With { .ID = 100 })

If documentTargetCollection.CanAdd Then
