How to: Print a TreeView Control

• Nov 13, 2018

This example illustrates the usage of printing links to print standard Windows Forms controls. The XtraPrinting library contains printing links specifically designed for several common controls. The following code links a Microsoft TreeView control to a printing system and generates a report which lists the TreeView nodes.

C#

using DevExpress.XtraPrintingLinks;
using DevExpress.XtraPrinting;
// ...

    // Create a new link.
    TreeViewLink treeViewLink1 = new TreeViewLink(printingSystem1);

    // Assign the TreeView control to be printed.
    treeViewLink1.TreeView = tvwSource;

    // Add the link to the collection.
    printingSystem1.Links.Add(treeViewLink1);
    printingSystem1.Links[0] = treeViewLink1;

    // Generate a report.
    printingSystem1.Links[0].CreateDocument();

    // Show the report to the user.
    printingSystem1.PreviewFormEx.Owner = this;
    printingSystem1.PreviewFormEx.Show();

VB.NET

Imports DevExpress.XtraPrintingLinks
Imports DevExpress.XtraPrinting
' ...

    ' Create a new link.
    Dim TreeViewLink1 As TreeViewLink = New TreeViewLink(PrintingSystem1)

    ' Assign the TreeView control to be printed.
    TreeViewLink1.TreeView = tvwSource

    ' Add the link to the collection.
    PrintingSystem1.Links.Add(New Link())
    PrintingSystem1.Links(0) = TreeViewLink1

    ' Generate a report.
    PrintingSystem1.Links(0).CreateDocument()

    ' Show the report to the user.
    PrintingSystem1.PreviewFormEx.Owner = Me
    PrintingSystem1.PreviewFormEx.Show()
