Sorting in Blazor DataGrid component
Sorting enables you to sort data in the Ascending or Descending order. To sort a column, click the column header.
To enable sorting in the DataGrid, set the AllowSorting to true. Sorting options can be configured through the GridSortSettings component.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" AllowSorting="true" Height="270">
<GridColumns>
<GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
<GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
Freight = 2.1 * x,
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order {
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
}
- DataGrid columns are sorted in the Ascending order. If you click the already sorted column, the sort direction toggles.
- You can apply and clear sorting by invoking SortColumn and ClearSorting methods.
- To disable sorting for a particular column, set the
AllowSortingproperty of GridColumn to false.
Initial sort
To sort at initial rendering, set the Field and
Direction in Columns property of GridSortSettings component.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" AllowSorting="true" Height="270">
<GridSortSettings>
<GridSortColumns>
<GridSortColumn Field="OrderDate" Direction="SortDirection.Ascending"></GridSortColumn>
<GridSortColumn Field="Freight" Direction="SortDirection.Descending"></GridSortColumn>
</GridSortColumns>
</GridSortSettings>
<GridColumns>
<GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
<GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
Freight = 2.1 * x,
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order {
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
}Multi-column sorting
You can sort more than one column in a DataGrid. To sort multiple columns, press and hold the CTRL key and click the column header. The sorting order will be displayed in the header while performing multi-column sorting.
To clear sorting for a particular column, press the “Shift + mouse left click”.
The
AllowSortingmust be true while enabling multi-column sort. SetAllowMultiSortingproperty as false to disable multi-column sorting.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" AllowSorting="true" AllowMultiSorting="true" Height="270">
<GridColumns>
<GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" TextAlign="TextAlign.Right" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="150"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" Type="ColumnType.Date" TextAlign="TextAlign.Right" Width="130"></GridColumn>
<GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" Width="120"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
Freight = 2.1 * x,
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order {
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
}Sort order
By default, the sorting order will be as Ascending -> Descending -> None.
When first click a column header it sorts the column in ascending. Again click the same column header, it will sort the column in descending. A repetitive third click on the same column header will clear the sorting.
Sorting events
During the sort action, the datagrid component triggers two events. The OnActionBegin event triggers before the sort action starts, and the OnActionComplete event triggers after the sort action is completed. Using these events you can perform the needed actions.
@using Syncfusion.Blazor.Grids
<SfGrid DataSource="@Orders" AllowSorting="true">
<GridEvents OnActionBegin="SortEvent" OnActionComplete="SortEvent" TValue="Order"></GridEvents>
<GridColumns>
<GridColumn Field=@nameof(Order.OrderID) HeaderText="Order ID" IsPrimaryKey="true" TextAlign="TextAlign.Right" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.CustomerID) HeaderText="Customer Name" Width="120"></GridColumn>
<GridColumn Field=@nameof(Order.OrderDate) HeaderText=" Order Date" Format="d" TextAlign="TextAlign.Right" Width="130" Type="ColumnType.Date"></GridColumn>
<GridColumn Field=@nameof(Order.Freight) HeaderText="Freight" Format="C2" TextAlign="TextAlign.Right" MinWidth="10" Width="120" MaxWidth="200"></GridColumn>
</GridColumns>
</SfGrid>
@code{
public List<Order> Orders { get; set; }
protected override void OnInitialized()
{
Orders = Enumerable.Range(1, 75).Select(x => new Order()
{
OrderID = 1000 + x,
CustomerID = (new string[] { "ALFKI", "ANANTR", "ANTON", "BLONP", "BOLID" })[new Random().Next(5)],
Freight = 2.1 * x,
OrderDate = DateTime.Now.AddDays(-x),
}).ToList();
}
public class Order {
public int? OrderID { get; set; }
public string CustomerID { get; set; }
public DateTime? OrderDate { get; set; }
public double? Freight { get; set; }
}
public void SortEvent(ActionEventArgs<Order> args) {
// You can get action information from the argument.
}
}Touch interaction
When you tap the datagrid header on touchscreen devices, the selected column header is sorted. A popup
is displayed for multi-column sorting. To sort multiple columns, tap the popup
, and then tap the desired datagrid headers.
The
AllowMultiSortingandAllowSortingshould be true then only the popup will be shown.
The following screenshot shows datagrid touch sorting.
You can refer to our Blazor DataGrid feature tour page for its groundbreaking feature representations. You can also explore our Blazor DataGrid example to understand how to present and manipulate data.
