### Complete MainPage.xaml Structure

Source: https://docs.telerik.com/devtools/winui/getting-started/first-steps-nuget

Full example of a page containing the RadDataGrid control definition.

```XAML
	<Page x:Class="GettingStarted.MainPage"
			xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
			xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
			xmlns:local="using:GettingStarted"
			xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
			xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
			xmlns:telerikGrid="using:Telerik.UI.Xaml.Controls.Grid"
			mc:Ignorable="d"
			Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
		<Grid>
			<telerikGrid:RadDataGrid x:Name="dataGrid" />
		</Grid>
	</Page>
```

--------------------------------

### Merge Generic.xaml in App.xaml

Source: https://docs.telerik.com/devtools/winui/getting-started/first-steps-nuget

Include the Telerik theme resources in the application's resource dictionary to ensure proper styling.

```XAML
	<Application.Resources>
		<ResourceDictionary>
			<ResourceDictionary.MergedDictionaries>
				<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
				<ResourceDictionary Source="ms-appx:///Telerik.WinUI.Controls/Themes/Generic.xaml"/>
				<!-- Other merged dictionaries here -->
			</ResourceDictionary.MergedDictionaries>
			<!-- Other app resources here -->
		</ResourceDictionary>
	</Application.Resources>
```

--------------------------------

### Add Required Namespaces

Source: https://docs.telerik.com/devtools/winui/getting-started/first-steps-nuget

Include these namespaces in your MainPage.xaml.cs file to support data binding and collection management.

```C#
		using Telerik.Core;
		using System.Collections.ObjectModel;
```

--------------------------------

### Implement Model and ViewModel

Source: https://docs.telerik.com/devtools/winui/getting-started/first-steps-nuget

Define a data model class inheriting from ViewModelBase and a ViewModel class to manage the collection of data items.

```C#
		public class Club : ViewModelBase
		{
			private string name;
			private DateTime established;
			private int stadiumCapacity;

			public Club(string name, DateTime established, int stadiumCapacity)
			{
				this.name = name;
				this.established = established;
				this.stadiumCapacity = stadiumCapacity;
			}

			public string Name
			{
				get { return this.name; }
				set
				{
					if (value != this.name)
					{
						this.name = value;
						this.OnPropertyChanged("Name");
					}
				}
			}

			public DateTime Established
			{
				get { return this.established; }
				set
				{
					if (value != this.established)
					{
						this.established = value;
						this.OnPropertyChanged("Established");
					}
				}
			}

			public int StadiumCapacity
			{
				get { return this.stadiumCapacity; }
				set
				{
					if (value != this.stadiumCapacity)
					{
						this.stadiumCapacity = value;
						this.OnPropertyChanged("StadiumCapacity");
					}
				}
			}
		}

		public class MyViewModel : ViewModelBase
		{
			private ObservableCollection<Club> clubs;

			public ObservableCollection<Club> Clubs
			{
				get
				{
					if (this.clubs == null)
					{
						this.clubs = this.CreateClubs();
					}

					return this.clubs;
				}
			}

			private ObservableCollection<Club> CreateClubs()
			{
				ObservableCollection<Club> clubs = new ObservableCollection<Club>();
				Club club;

				club = new Club("Liverpool", new DateTime(1892, 1, 1), 45362);
				clubs.Add(club);

				club = new Club("Manchester Utd.", new DateTime(1878, 1, 1), 76212);
				clubs.Add(club);

				club = new Club("Chelsea", new DateTime(1905, 1, 1), 42055);
				clubs.Add(club);

				return clubs;
			}
		}
```

--------------------------------

### Declare DataGrid Namespace

Source: https://docs.telerik.com/devtools/winui/getting-started/first-steps-nuget

Add the required XML namespace declaration to use Telerik Grid controls in XAML.

```XAML
		xmlns:telerikGrid="using:Telerik.UI.Xaml.Controls.Grid"
```

--------------------------------

### Define RadDataGrid Control

Source: https://docs.telerik.com/devtools/winui/getting-started/first-steps-nuget

Instantiate the RadDataGrid control within the XAML layout.

```XAML
		<telerikGrid:RadDataGrid x:Name="dataGrid" />
```

--------------------------------

### Bind Data to RadDataGrid in XAML

Source: https://docs.telerik.com/devtools/winui/getting-started/first-steps-nuget

Sets the DataContext to a ViewModel and binds the ItemsSource property of the RadDataGrid to a collection.

```xml
	<Window x:Class="GettingStarted.MainWindow"
			xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
			xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
			xmlns:local="using:GettingStarted"
			xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
			xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
			xmlns:telerikGrid="using:Telerik.UI.Xaml.Controls.Grid"
			mc:Ignorable="d"
			Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">		
		<Grid>
			<Grid.DataContext>
				<local:MyViewModel />
			</Grid.DataContext>
			<telerikGrid:RadDataGrid x:Name="dataGrid" ItemsSource="{Binding Clubs}"/>
		</Grid>
	</Window>
```
