.NET MAUI DataGrid Columns Cell Templates

This article describes how to extend the functionality of a DataGrid column and define custom content and edit templates using the CellContentTemplate and CellEditTemplate properties.

  • CellContentTemplate (DataTemplate): Defines the appearance of each cell associated with the concrete column. CellContentTemplate gives you the opportunity to wrap the text inside each DataGrid column. You can add a Label as a content of the Text, Template Column and wrap its text using the Label's LineBreakMode property.
  • CellEditTemplate (DataTemplate): Defines the editor associated with the concrete column. The CellEditTemplate is displayed when the cell is in edit mode.

Cell Content Template Example

The following example demonstrates how to use the CellContentTemplate property to customize your columns. We set a RadDateTimePicker as a CellContentTemplate for the DataGrid Date Column (Date Established) and a Switch - for the DataGrid Boolean Column (Champion).

1. Use the following snippet to declare a RadDataGrid in XAML:

<telerik:RadDataGrid x:Name="dataGrid" 
                     ItemsSource="{Binding Clubs}" 
                     AutoGenerateColumns="False" 
                     UserEditMode="Cell">
    <telerik:RadDataGrid.Columns>
        <telerik:DataGridTextColumn PropertyName="Name" 
                                    Width="130"
                                    SizeMode="Fixed"
                                    HeaderText="Name">
            <telerik:DataGridColumn.CellContentTemplate>
                <DataTemplate>
                    <Label Text="{Binding Name}" 
                           LineBreakMode="TailTruncation"
                           VerticalOptions="Center"
                           Margin="5, 0" />
                </DataTemplate>
            </telerik:DataGridColumn.CellContentTemplate>
        </telerik:DataGridTextColumn>
        <telerik:DataGridBooleanColumn PropertyName="IsChampion" 
                                       HeaderText="Champion?">
            <telerik:DataGridColumn.CellContentTemplate>
                <DataTemplate>
                    <Switch IsToggled="{Binding IsChampion}"
                            VerticalOptions="Center"/>
                </DataTemplate>
            </telerik:DataGridColumn.CellContentTemplate>
        </telerik:DataGridBooleanColumn>
        <telerik:DataGridDateColumn PropertyName="Established" 
                                    HeaderText="Date Established">
            <telerik:DataGridColumn.CellContentTemplate>
                <DataTemplate>
                    <telerik:RadDateTimePicker Date="{Binding Established}" 
                                               DisplayStringFormat="yyyy/MMM/dd"
                                               VerticalOptions="Center"/>
                </DataTemplate>
            </telerik:DataGridColumn.CellContentTemplate>
        </telerik:DataGridDateColumn>
        <telerik:DataGridTemplateColumn HeaderText="Template Column">
            <telerik:DataGridColumn.CellContentTemplate>
                <DataTemplate>
                    <Label Text="{Binding Country}" 
                           Margin="0, 5"
                           HorizontalOptions="Center"
                           VerticalTextAlignment="Center"/>
                </DataTemplate>
            </telerik:DataGridColumn.CellContentTemplate>
        </telerik:DataGridTemplateColumn>
    </telerik:RadDataGrid.Columns>
</telerik:RadDataGrid>

2. Add the following namespaces:

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

3. Declare the ViewModel class:

public class ViewModel
{
    private ObservableCollection<Club> clubs;

    public ObservableCollection<Club> Clubs => clubs ?? (clubs = CreateClubs());

    private ObservableCollection<Club> CreateClubs()
    {
        return new ObservableCollection<Club>
        {
            new Club("UK Liverpool ", new DateTime(1892, 1, 1), 54074, "England", "Liverpool", "Premier League", null),
            new Club("Manchester Utd.", new DateTime(1878, 1, 1), 74310, "England", "Manchester", "Premier League", 594.3) { IsChampion = true },
            new Club("Chelsea", new DateTime(1905, 1, 1), 42055, "England", "London","UEFA Champions League", 481.3),
            new Club("Barcelona", new DateTime(1899, 1, 1), 99354, "Spain", "Barcelona", "La Liga", 540.5)
        };
    }
}

4. And the Club custom object:

public class Club : NotifyPropertyChangedBase
{
    private string name;
    private DateTime established;
    private int stadiumCapacity;
    private bool isChampion;
    private string country;
    private string city;
    private string championship;
    private double? revenue;

    public Club(string name, DateTime established, int stadiumCapacity, string country, string city, string championship, double? revenue)
    {
        Name = name;
        Established = established;  
        StadiumCapacity = stadiumCapacity;
        Country = country;
        City = city;
        Championship = championship;
        Revenue = revenue;
    }

    public string Name
    {
        get { return this.name; }
        set { this.UpdateValue(ref this.name, value); }
    }
    public DateTime Established
    {
        get { return this.established; }
        set { this.UpdateValue(ref this.established, value); }
    }

    public int StadiumCapacity
    {
        get { return this.stadiumCapacity; }
        set { this.UpdateValue(ref this.stadiumCapacity, value); }
    }

    public bool IsChampion
    {
        get { return this.isChampion; }
        set { this.UpdateValue(ref this.isChampion, value); }
    }

    public string Country
    {
        get { return this.country; }
        set { this.UpdateValue(ref this.country, value); }
    }

    public string City
    {
        get { return this.city; }
        set { this.UpdateValue(ref this.city, value); }
    }

    public string Championship       
    {
        get { return this.championship; }
        set { this.UpdateValue(ref this.championship, value); }
    }

    public double? Revenue
    {
        get { return this.revenue; }
        set { this.UpdateValue(ref this.revenue, value); }
    }

    public List<string> Championships => new List<string> { "UEFA Champions League", "Premier League", "La Liga" };
}

DataGrid Cell Content Template

Cell Edit Template Example

The following example demonstrates how to use the CellEditTemplate property to customize your columns. Here, for the DataGrid Boolean Column (Champion) we set a CellEditTemplate containing a Switch and two Buttons for confirming or canceling the edit operation. The edit template is visualized when the cell is in edit mode.

1. Use the following snippet to declare a RadDataGrid in XAML:

<telerik:RadDataGrid x:Name="dataGrid"
                     ItemsSource="{Binding Clubs}"
                     AutoGenerateColumns="False"
                     SelectionMode="None"
                     UserEditMode="Cell">
    <telerik:RadDataGrid.Columns>
        <telerik:DataGridTextColumn PropertyName="Name"
                                    HeaderText="Name">
            <telerik:DataGridColumn.CellEditTemplate>
                <DataTemplate>
                    <VerticalStackLayout Spacing="2"
                                         Margin="2">
                        <telerik:RadEntry Text="{Binding Item.Name, Mode=TwoWay}">
                            <VisualElement.Behaviors>
                                <telerik:RadEventToCommandBehavior EventName="Completed"
                                                                   Command="{Binding CommitEditCommand}" />
                            </VisualElement.Behaviors>
                        </telerik:RadEntry>
                        <Button Text="Cancel"
                                Command="{Binding CancelEditCommand}" />

2. Add the following namespaces:

xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"

3. Declare the ViewModel class:

public class ViewModel
{
    private ObservableCollection<Club> clubs;

    public ObservableCollection<Club> Clubs => clubs ?? (clubs = CreateClubs());

    private ObservableCollection<Club> CreateClubs()
    {
        return new ObservableCollection<Club>
        {
            new Club("UK Liverpool ", new DateTime(1892, 1, 1), 54074, "England", "Liverpool", "Premier League", null),
            new Club("Manchester Utd.", new DateTime(1878, 1, 1), 74310, "England", "Manchester", "Premier League", 594.3) { IsChampion = true },
            new Club("Chelsea", new DateTime(1905, 1, 1), 42055, "England", "London","UEFA Champions League", 481.3),
            new Club("Barcelona", new DateTime(1899, 1, 1), 99354, "Spain", "Barcelona", "La Liga", 540.5)
        };
    }
}

4. And the Club custom object:

public class Club : NotifyPropertyChangedBase
{
    private string name;
    private DateTime established;
    private int stadiumCapacity;
    private bool isChampion;
    private string country;
    private string city;

    set { this.UpdateValue(ref this.championship, value); }
}

public double? Revenue
{
    get { return this.revenue; }
    set { this.UpdateValue(ref this.revenue, value); }
}

public List&lt;string&gt; Championships =&gt; new List&lt;string&gt; { "UEFA Champions League", "Premier League", "La Liga" };

}
