Using TX Text Control .NET with Component One's Print Preview

In this sample we would like to show you another .NET component that works well with the TX Text Control .NET. The ComponentOne Preview .NET component offers some advantages over the standard VS .NET print preview.

ComponentOne's control comes with the C1PrintPreview component and the C1PrintDocument component. In this sample, we are going to use the preview component only.

Using the components together is quite straight-forward: You need to create a custom PrintController, so that TX Text Control does not send its contents to the standard printer. The dummy PrintController does not do anything except return a Graphics object in the OnStartPage handler. As you cannot create a Graphics object without a Form or a Screen object, a reference to the parent form has to be set with the SetParent method.

Private Class MyPrintController
    Inherits System.Drawing.Printing.PrintController
 
    Private parent As Form1
 
    Public Sub New()
        MyBase.New()
    End Sub
 
    Public Sub SetParent(ByVal form As Form1)
        parent = form
    End Sub
 
    Public Overloads Overrides Function OnStartPage(ByVal document_
        As System.Drawing.Printing.PrintDocument, ByVal e As System._
        Drawing.Printing.PrintPageEventArgs) As System.Drawing.Graphics
            OnStartPage = parent.CreateGraphics()
    End Function
 
    Public Overloads Overrides Sub OnEndPage(ByVal document As_
        System.Drawing.Printing.PrintDocument, ByVal e As System.Drawing._
        Printing.PrintPageEventArgs)
    End Sub
 
    Public Overloads Overrides Sub OnEndPrint(ByVal document As_
        System.Drawing.Printing.PrintDocument, ByVal e As System.Drawing._
        Printing.PrintEventArgs)
    End Sub
 
    Public Overloads Overrides Sub OnStartPrint(ByVal document As_
        System.Drawing.Printing.PrintDocument, ByVal e As System.Drawing._
        Printing.PrintEventArgs)
    End Sub

The CreateGraphics method of this reference can be used in the OnStartPage event handler. Have a look at the code to see how it works.

Note that at least TX Text Control .NET 10.1 trial, a trial version of ComponentOne Preview .NET and Visual Studio VB .NET are required to run this sample.
