Create a Custom DataGridColumn in MAUI DataGrid

In.NET MAUI DataGrid (SfDataGrid) allows you to create custom DataGridColumn by following the below steps.

Step 1 - To create a custom column, you must inherit from the DataGridColumn class and specify the DataGridColumn.CellType property.

Step 2 - A Custom CellRenderer cclass must be created for the custom column by customizing the DataGridCellRenderer<D, E>.

Step 3 - In the created cell renderer class, you should override the following methods. OnCreateDisplayUIView() – Generate the data to be placed in the grid cell. OnInitializeDisplayView() – To set up the cell content loaded in the grid cell with the necessary settings.

Step 4 - You must add the custom column to the SfDataGrid.Columns collection and its renderer to SfDataGrid.CellRenderers collection.

For example, refer the below example in which a custom column is created for loading a Stepper control in the grid columns. A custom renderer class is written to load Stepper control as display.

XAML

<syncfusion:SfDataGrid x:Name="dataGrid"  
                           ItemsSource="{Binding Employees}"       
                           ColumnWidthMode="Auto"
                           AutoGenerateColumnsMode="None">
        <syncfusion:SfDataGrid.Columns>
            <local:StepperColumn MappingName="OrderID"/>
        </syncfusion:SfDataGrid.Columns>
</syncfusion:SfDataGrid>

C#

Creating Stepper Column

public class StepperColumn : DataGridColumn
{
    public StepperColumn()
    {
        var cellType = typeof(DataGridColumn).GetRuntimeProperties().FirstOrDefault((property) => property.Name == "CellType");
        cellType.SetValue(this, "Stepper");
    }
}

Custom cell renderer for StepperColumn

public class StepperColumnRenderer : DataGridCellRenderer<Stepper, Stepper>
{
    public StepperColumnRenderer()
    {
    }

    protected override Stepper OnCreateDisplayUIView()
    {
        return new Stepper();
    }
}

MainPage

public partial class MainPage : ContentPage
{
    
    public MainPage()
    {
        InitializeComponent();
        dataGrid.CellRenderers.Add("Stepper", new StepperColumnRenderer());
    }	
}
