+This repository contains sample which shows localization of Syncfusion [WPF DataGrid](https://www.syncfusion.com/wpf-controls/datagrid) (SfDataGrid).
 
-![Localized WPF DataGrid](wpf-datagrid-localization.PNG)
+[Localization](https://help.syncfusion.com/wpf/localization) is the process of translating the application resources into different language for the specific cultures. You can localize the WPF DataGrid by adding a resource file for each language.
+
+### Changing application culture
+
+When you change the application culture, you can localize the application based on application culture by creating .resx file.
+
+#### C#
+
+``` csharp
+public partial class MainWindow
+{
+    public MainWindow() 
+    {
+        System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("de");   
+        InitializeComponent();  
+    }
+}
+```
+
+#### VB
+
+``` vb
+Partial Public Class MainWindow
+    Public Sub New()
+        System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("de")
+        InitializeComponent()
+    End Sub
+End Class
+```
+
+### Creating .resx files
+
+You can create .resx files for any language by following these steps:
+
+1. Right-click your project and add a new folder named as `Resources`.
+
+2. Add the [default resource files](https://github.com/syncfusion/wpf-controls-localization-resx-files) to the libraries you are using to the `Resources` folder and ensure `AccessModifier` is specified as Public.
+
+**Note:**
+Consider, you are using `SfDataGrid` and `Ribbon` in your application. Then, you need to copy and include `Syncfusion.SfGrid.WPF.resx` (since `SfDataGrid` present in `Syncfusion.SfGrid.WPF` library) and `Syncfusion.Tools.Wpf.resx` (since `Ribbon` present in `Syncfusion.Tools.WPF` library) files in your application under `Resources` folder. So, now you can know the key names and values of default stings used in `Syncfusion.Tools.WPF.dll` and `Syncfusion.SfGrid.WPF.dll` libraries.

+
+3. Now, right-click `Resources` folder and select Add and then `NewItem`. In the `Add New Item` wizard, select the Resource File option and name the filename as `Syncfusion.SfGrid.WPF.<culture name>.resx`. For example, you have to give name as `Syncfusion.SfGrid.WPF.de.resx` for `German` culture. In the same way, add new resource files for other libraries used in your application.

+
+4. Now, select Add and add resource file for German culture in `Resources` folder and set `AccessModifier` property to No code generation.

+
+5. Now, you can copy the key names from the default resource files and assign values based on the culture and the resource files’ targets.
