# How-to-Serialize-template-column-content-in-.NET-MAUI-DataGrid--SfDataGrid-
-This demo shows how to Serialize template column content in .NET MAUI DataGrid (SfDataGrid)?
+
+This sample shows how to serialize and deserialize template column content in the .NET MAUI DataGrid (SfDataGrid).
+
+The example demonstrates placing a `DataGridTemplateColumn` with a `CellTemplate` (defined in XAML resources), wiring a custom `DataGridSerializationController` to preserve template column configuration, and using simple Serialize/Deserialize buttons to write/read the grid state to an XML file in app data.
+
+**Refer to the official UG for more details:**

+- [Serialization and Deserialization in .NET MAUI DataGrid (SfDataGrid)](https://help.syncfusion.com/maui/datagrid/serialization)
+
+## XAML
+
+The grid includes a `DataGridTemplateColumn` whose `CellTemplate` is stored in page resources with x:Key="cellTemplate".
+
+```xml
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+## C#
+
+To support serialization and restore the `CellTemplate` after deserialization, the sample adds a small extension of `DataGridSerializationController` that looks up the template in the page `ResourceDictionary` and reassigns it when restoring column properties.
+
+
+```csharp
+public MainPage()
+{
+ InitializeComponent();
+ this.dataGrid.SerializationController = new SerializationControllerExt(this.dataGrid, Resources);
+ this.dataGrid1.SerializationController = new SerializationControllerExt(this.dataGrid1, Resources);
+}
+
+private void Button_Clicked(object sender, EventArgs e)
+{
+ string localPath = Path.Combine(FileSystem.AppDataDirectory, "DataGrid.xml");
+ using (var file = File.Create(localPath))
+ {
+ dataGrid.Serialize(file);
+ }
+}
+
+private void Button_Clicked_1(object sender, EventArgs e)
+{
+ string localPath = Path.Combine(FileSystem.AppDataDirectory, "DataGrid.xml");
+
+ using (var file = File.Open(localPath, FileMode.Open))
+ {
+ dataGrid1.Deserialize(file);
+ }
+}
+
+public class SerializationControllerExt : DataGridSerializationController
+{
+ private readonly ResourceDictionary _pageResources;
+
+ public SerializationControllerExt(SfDataGrid grid, ResourceDictionary pageResources)
+ : base(grid)
+ {
+ _pageResources = pageResources;
+ }
+
+ protected override void RestoreColumnProperties(SerializableDataGridColumn serializableColumn, DataGridColumn column)
+ {
+ base.RestoreColumnProperties(serializableColumn, column);
+
+ if (column is DataGridTemplateColumn templateColumn &&
+ string.Equals(templateColumn.MappingName, "Name", StringComparison.Ordinal))
+ {
+ if (_pageResources.TryGetValue("cellTemplate", out var template) &&
+ template is DataTemplate dataTemplate)
+ {
+ templateColumn.CellTemplate = dataTemplate;
+ }
+ }
+ }
+}
+```
+
+## How it works
+- The grid's `SerializationController` is set to `SerializationControllerExt` which inherits from `DataGridSerializationController`.
+- When the grid is serialized, column definitions including type and properties are written to the stream (here, an XML file in `FileSystem.AppDataDirectory`).
+- On deserialization the base controller restores basic column properties; `SerializationControllerExt.RestoreColumnProperties` runs afterward to reconnect runtime-only artifacts such as `DataTemplate` instances that live in the page `ResourceDictionary`.
