Explicitly Updating the Binding Source Sample
This sample shows how to explicitly update binding sources in a form submit scenario. For more information, see How to: Control When the TextBox Text Updates the Source.
This sample demonstrates a specific feature of the Windows Presentation Foundation and, consequently, does not follow application development best practices. For comprehensive coverage of Windows Presentation Foundation (WPF) and Microsoft .NET Framework application development best practices, refer to the following as appropriate:

Building the Sample
Install the Windows Software Development Kit (SDK) and open its build environment command window. On the Start menu, point to All Programs, Microsoft Windows SDK, and then click CMD Shell.
Download the sample, usually from the software development kit (SDK) documentation, to your hard disk drive.
To build the sample from the build environment command window, go to the source directory of the sample. At the command prompt, type MSBUILD.
To build the sample in Microsoft Visual Studio, load the sample solution or project file and then press CTRL+SHIFT+B.
Running the Sample
To run the compiled sample from the build environment command window, execute the .exe file in the Bin\Debug or Bin\Release folder contained under the sample source code folder.
To run the compiled sample with debugging in Visual Studio, press F5.
Remarks
Two entry TextBox elements are bound to an object data source. Entries to both TextBox elements can be edited before their content is explicitly updated back to the source of the binding. This is useful in form submission scenarios where you want to defer updating the binding sources until all entries in the form are completed.
