How to create WinUI DataGrid with multiple header rows (Stacked Header Rows)?
WinUI DataGrid (SfDataGrid) supports to add additional unbound header rows using StackedHeaderRows. This can be used to add multiple header rows for the SfDataGrid and to group one or more columns under each stacked header. Each StackedHeaderRow contains StackedColumns where each StackedColumn contains a number of child columns. You can set the text displayed in the stacked column by using StackedColumn.HeaderText property.
<syncfusion:SfDataGrid x:Name="dataGrid"
ColumnWidthMode="Star"
Margin="10"
ItemsSource="{Binding OrdersListDetails}">
<syncfusion:SfDataGrid.DataContext>
<local:ViewModel />
</syncfusion:SfDataGrid.DataContext>
<syncfusion:SfDataGrid.StackedHeaderRows>
<grid:StackedHeaderRow>
<grid:StackedHeaderRow.StackedColumns>
<grid:StackedColumn ChildColumns="OrderID,CustomerID,ProductName,Quantity,UnitPrice,ContactNumber,ShipCountry"
HeaderText="Order Shipment Details" />
</grid:StackedHeaderRow.StackedColumns>
</grid:StackedHeaderRow>
<grid:StackedHeaderRow>
<grid:StackedHeaderRow.StackedColumns>
<grid:StackedColumn ChildColumns="OrderID,ProductName,Quantity,UnitPrice" HeaderText="Order Details" />
<grid:StackedColumn ChildColumns="CustomerID,ContactNumber" HeaderText="Customer Details" />
<grid:StackedColumn ChildColumns="ShipCountry" HeaderText="Shipment Details " />
</grid:StackedHeaderRow.StackedColumns>
</grid:StackedHeaderRow>
</syncfusion:SfDataGrid.StackedHeaderRows>
</syncfusion:SfDataGrid>
Stacked Headers using Data Annotation
It is possible to add the stacked headers using GroupName property of Data Annotations Display attributes.
/// <summary>
/// Gets or sets the order ID.
/// </summary>
/// <value>The order ID.</value>
[Display(GroupName = "Order Details", Name = "Order ID")]
public int OrderID
{
get
{
return this._OrderID;
}
set
{
this._OrderID = value;
this.OnPropertyChanged("OrderID");
}
}
/// <summary>
/// Gets or sets the Product.
/// </summary>
/// <value>The Product.</value>
[Display(GroupName = "Order Details", Name = "Product Name")]
public string ProductName
{
get
{
return this._product;
}
set
{
this._product = value;
this.OnPropertyChanged("ProductName");
}
}
/// <summary>
/// Gets or sets quantity
/// </summary>
/// <value>the quantity</value>
[Display(GroupName = "Order Details", Name = "Quantity")]
public int Quantity
{
get
{
return this._Quantity;
}
set
{
_Quantity = value;
OnPropertyChanged("Quantity");
}
}
/// <summary>
/// Gets or sets the unit price.
/// </summary>
/// <value>The unit price.</value>
[Display(GroupName = "Order Details", Name = "Unit Price")]
[DataType(DataType.Currency)]
public double UnitPrice
{
get
{
return _unitPrice;
}
set
{
_unitPrice = value;
OnPropertyChanged("UnitPrice");
}
}
/// <summary>
/// Gets or sets the customer ID.
/// </summary>
/// <value>The customer ID.</value>
[Display(GroupName = "Customer Details", Name = "Customer ID")]
public string CustomerID
{
get
{
return this._CustomerID;
}
set
{
this._CustomerID = value;
this.OnPropertyChanged("CustomerID");
}
}
/// <summary>
/// Gets or sets quantity
/// </summary>
/// <value>the quantity</value>
[Display(GroupName = "Customer Details", Name = "Contact Number")]
public int ContactNumber
{
get
{
return this._contactNumber;
}
set
{
_contactNumber = value;
OnPropertyChanged("ContactNumber");
}
}
/// <summary>
/// Gets or sets the ShipAddress.
/// </summary>
/// <value>The ShipAddress.</value>
[Display(GroupName = "Shipment Details", Name = "ShipCountry")]
public string ShipCountry
{
get
{
return this._shipaddress;
}
set
{
this._shipaddress = value;
this.OnPropertyChanged("ShipCountry");
}
} 
Changing stacked header row height
You can change the height of stacked header rows by using SfDataGrid.QueryRowHeight event.
using Syncfusion.UI.Xaml.DataGrid;
this.dataGrid.QueryRowHeight += DataGrid_QueryRowHeight;
private void DataGrid_QueryRowHeight(object sender, Syncfusion.UI.Xaml.DataGrid.QueryRowHeightEventArgs e)
{
if (e.RowIndex < this.dataGrid.GetHeaderIndex())
{
e.Height = 50;
e.Handled = true;
}
}Styling Stacked Headers
The appearance of stacked header can be customized by using the keys SyncfusionGridStackedHeaderCellControlBackground and SyncfusionGridStackedHeaderCellControlForeground.
<Grid>
<Grid.Resources>
<SolidColorBrush x:Key="SyncfusionGridStackedHeaderCellControlBackground" Color="LightSalmon"/>
<SolidColorBrush x:Key="SyncfusionGridStackedHeaderCellControlForeground" Color="DarkBlue"/>
</Grid.Resources>
<syncfusion:SfDataGrid x:Name="dataGrid"
ColumnWidthMode="Star"
Margin="10"
ItemsSource="{Binding OrdersListDetails}">
<syncfusion:SfDataGrid.DataContext>
<local:ViewModel />
</syncfusion:SfDataGrid.DataContext>
<syncfusion:SfDataGrid.StackedHeaderRows>
<grid:StackedHeaderRow>
<grid:StackedHeaderRow.StackedColumns>
<grid:StackedColumn ChildColumns="OrderID,CustomerID,ProductName,Quantity,UnitPrice,ContactNumber,ShipCountry"
HeaderText="Order Shipment Details" />
</grid:StackedHeaderRow.StackedColumns>
</grid:StackedHeaderRow>
<grid:StackedHeaderRow>
<grid:StackedHeaderRow.StackedColumns>
<grid:StackedColumn ChildColumns="OrderID,ProductName,Quantity,UnitPrice" HeaderText="Order Details" />
<grid:StackedColumn ChildColumns="CustomerID,ContactNumber" HeaderText="Customer Details" />
<grid:StackedColumn ChildColumns="ShipCountry" HeaderText="Shipment Details " />
</grid:StackedHeaderRow.StackedColumns>
</grid:StackedHeaderRow>
</syncfusion:SfDataGrid.StackedHeaderRows>
</syncfusion:SfDataGrid>
Take a moment to peruse the WinUI DataGrid - Stacked Headers documentation, where
you can find about stacked headers with code examples.
