Declaration

VB.NET

csharp

public class GridSortInfo :
    DependencyObject,
    IColumnInfo,

    Implements IColumnInfo,
               IMergeWithPreviousGroup

Remarks

The GridControl.SortInfo collection maintains the sorted and grouped columns. Individual elements contained within this collection are represented by the GridSortInfo class. A GridSortInfo object specifies a column (GridSortInfo.FieldName), its sort order (GridSortInfo.SortOrder) and a grouping flag, which is set to true if grouping is applied to this column.

Adding elements to the GridControl.SortInfo collection applies sorting or grouping by specific columns. Removing elements from this collection clears sorting/grouping by the corresponding column.

The GridSortInfo objects that refer to the columns used to group data always come first in the collection. The number of such elements is specified by the GridSortInfoCollection.GroupCount property. The subsequent elements in the collection refer to the columns used for data sorting only.

To learn more, see Sorting in Code.

Example

This example shows how to apply data sorting and grouping in XAML.

Since group rows are always sorted, data grouping requires data sorting. Sorting applied to group columns takes priority over other columns. To group data by one column in XAML, do the following:

Create a GridSortInfo object and specify its GridSortInfo.FieldName and GridSortInfo.SortOrder properties. The GridSortInfo.FieldName property specifies the grouping column by its field name.
Add the GridSortInfo object to the grid’s GridControl.SortInfo collection. This object must be the first element in this collection.
Finally, set the grid’s GridControl.GroupCount property to 1. This specifies that the first element in the GridControl.SortInfo collection corresponds to the grouping column.

The image below shows the result:

XAML

csharp

using System.ComponentModel;
using DevExpress.Xpf.Grid;

public Window1() {
    InitializeComponent();
    grid.DataSource =
        new dsNwindProductsTableAdapters.ProductsTableAdapter().GetData();
    CreateSortInfo(grid);
}
private void CreateSortInfo(GridControl grid) {
    grid.SortInfo.Add(new GridSortInfo("UnitPrice", ListSortDirection.Descending));
    grid.SortInfo.Add(new GridSortInfo("ProductName", ListSortDirection.Ascending));
    grid.GroupCount = 1;
}

xaml

    <dxg:GridControl.Columns>
        <dxg:GridColumn FieldName="ProductName"/>
        <dxg:GridColumn FieldName="UnitPrice"/>
        <dxg:GridColumn FieldName="UnitsOnOrder" Header="Units On Order"/>
    </dxg:GridControl.Columns>
