Handling threads in WPF

In the previous recipe, we looked at the best way to run operations in non-UI/background threads in Windows Forms. The concerns that we addressed for Windows Forms exist for WPF as well. You cannot access any control on the UI thread from the background thread. In such a case, how do you pass data to a UI thread? In this recipe, we are going to discuss the best approach to doing this.

How to do it…

  1. Launch Visual Studio 2012. Create a project of type WPF Application and name it ThreadHandlingWPF.

  2. Open MainWindow.xml in the design mode. Design the UI so that it looks similar to the following screenshot:

  3. Name the controls as detailed in the following table:

    Control

    Description

    Name

    Textblock

    To hold the path of the selected folder.

    txtDirectory

    Button

    To display the select folder dialog. Its text will be "…"

    btnSelectDir

    Button

    To start listing the files in the selected directory.

    btnListFiles

    ListBox

    To display the file list.

    lstFiles

  4. Open MainWindow...
