How to perform header truncation in .NET MAUI DataGrid?

In this article, we will demonstrate how to truncate the header text in DataGridHeaderCell by customizing the DataGridHeaderCellRenderer in the .NET MAUI DataGrid.

XAML

    <syncfusion:SfDataGrid x:Name="dataGrid"
                           GridLinesVisibility="Both"
                           HeaderGridLinesVisibility="Both"
                           AutoGenerateColumnsMode="None"
                           ItemsSource="{Binding Employees}">
 
        <syncfusion:SfDataGrid.Columns>
            <syncfusion:DataGridTextColumn MappingName="Name"
                                           HeaderText="Customer Name" />
            <syncfusion:DataGridTextColumn MappingName="Title"
                                           HeaderText="Designation" />
            <syncfusion:DataGridDateColumn MappingName="BirthDate"
                                           HeaderText="Joining Date" />
            <syncfusion:DataGridTextColumn MappingName="Gender"
                                           HeaderText="Gender" />
 
        </syncfusion:SfDataGrid.Columns>
    </syncfusion:SfDataGrid>

C#
The code below illustrates how to perform header truncation with custom Header Cell renderer.

public partial class MainPage : ContentPage
{
    public MainPage()
    {
        InitializeComponent();
        dataGrid.CellRenderers.Remove("ColumnHeader");
        dataGrid.CellRenderers.Add("ColumnHeader", new DataGridHeaderCellRendererExt());
    }
}
 
public class DataGridHeaderCellRendererExt : DataGridHeaderCellRenderer
{
    protected override void OnInitializeDisplayView(DataColumnBase dataColumn, SfDataGridContentView? view)
    {
        base.OnInitializeDisplayView(dataColumn, view);
 
        if (view!.Content is Grid headerView)
        {
            var label = headerView.Children.FirstOrDefault(child => child is SfDataGridHeaderLabel);
 
            if (label != null && label is SfDataGridHeaderLabel newLabel)
            {
                newLabel.LineBreakMode = LineBreakMode.CharacterWrap;
            }
        }
    }
}
