How to keep cell style unchanged when selecting row in .NET MAUI DataGrid (SfDataGrid) ?

In this article, we will demonstrate how to maintain the cell style unchanged when a row is selected in the .NET MAUI DataGrid.

xaml

<ContentPage.BindingContext>
    <local:EmployeeViewModel x:Name="viewModel"/>
</ContentPage.BindingContext>

<syncfusion:SfDataGrid x:Name="dataGrid"
                       GridLinesVisibility="Both"
                       SelectionMode="Single"
                       NavigationMode="Row"
                       HeaderGridLinesVisibility="Both"
                       AutoGenerateColumnsMode="None"
                       ColumnWidthMode="Auto"
                       ItemsSource="{Binding Employees}">

    <syncfusion:SfDataGrid.DefaultStyle>
        <syncfusion:DataGridStyle RowBackground="LightBlue" HeaderRowBackground="LightBlue" HeaderRowTextColor="Black"
                                  RowTextColor="Black"
                                  SelectionBackground="Gray"
                                  SelectedRowTextColor="White" />
    </syncfusion:SfDataGrid.DefaultStyle>

    <syncfusion:SfDataGrid.Columns>
        <syncfusion:DataGridNumericColumn MappingName="EmployeeID" HeaderText="Employee ID" Format="#" />
        <syncfusion:DataGridTextColumn MappingName="Name" HeaderText="Employee Name" />
        <syncfusion:DataGridTextColumn MappingName="Title" HeaderText="Designation" />
        <syncfusion:DataGridDateColumn MappingName="HireDate" HeaderText="Hire Date" />
    </syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>

C#
The code below illustrates how to maintain the cell style unchanged when a row is selected in the DataGrid.

public MainPage()
{
    InitializeComponent();
    dataGrid.CellRenderers.Remove("Text");
    dataGrid.CellRenderers.Add("Text", new CustomRenderer());
}

public class CustomRenderer : DataGridCellRenderer<View, View>
{
    protected override void OnSetCellStyle(DataColumnBase dataColumn)
    {
        base.OnSetCellStyle(dataColumn);

        if (dataColumn != null)
        {
            var gridStyle = this.DataGrid?.DefaultStyle;
            DataGridCell gridCell = dataColumn.ColumnElement;
            var mappingName = dataColumn.DataGridColumn.MappingName;

            if ((mappingName == "Name"))
            {
                var label = gridCell.Children[0] as Label;
                if (label != null && gridCell != null)
                {
                    label.TextColor = Colors.White;
                    gridCell.BackgroundColor = Colors.Orange;
                }
            }

            gridStyle = null;
            mappingName = null;
            gridCell = null;
        }
    }
}
