Syntax

C#
public SortDirection SortDirection { get; set; }
Visual Basic
Public Property SortDirection As SortDirection
	Get
	Set
Visual C++
public:
property SortDirection SortDirection {
	SortDirection get ();
	void set (SortDirection value);
}
F#
member SortDirection : SortDirection with get, set

Property Value

Type: SortDirection
The sort direction.

Remarks

.Net Grid sorting depends on headers. Sorted columns are stored in Header.SortedColumns. To enable sorting you have to use Column.SortDirection property. Calling this property for multiple columns sets multiple sorting by these columns. To cancel sorting, call Clear()()()()Header.SortedColumns.Clear().

    //Add a new header on the top hierarchical level (level 0)
    Header header = new Header();
    header.Add(new Column("Column1"));
    header.Add(new Column("Column2"));
    header.Add(new Column("Column3"));
    grid.Headers.Add(header);

    Console.WriteLine("Sorted columns count: {0}", header.GroupedColumns.Count);

    header.SortedColumns.Clear();

    //Set multiple sort by two columns
    header["Column1"].SortDirection = SortDirection.Ascending;
    header["Column3"].SortDirection = SortDirection.Ascending;

    Console.WriteLine("Columns count: {0}", header.Count);
    Console.WriteLine("Sorted columns count: {0}", header.SortedColumns.Count);

    //Change the sort direction
    header["Column3"].SortDirection = SortDirection.Descending;

    //Iterate in all sorted columns
    foreach (Column column in header.SortedColumns)
    {
        Console.WriteLine("Sorted column: id = '{0}', index = {1}, visible index = {2}, sort level = {3}, sort direction = {4}", column.Id, column.Index, column.VisibleIndex, column.SortLevel, column.SortDirection);
    }

    //Remove sort
    header.SortedColumns.Clear();
    Console.WriteLine("Columns count: {0}", header.Count);
    Console.WriteLine("Sorted columns count: {0}", header.SortedColumns.Count);
}

//Console output:
Sorted columns count: 0
Columns count: 3
Sorted columns count: 2
Sorted column: id = 'Column1', index = 0, visible index = 0, sort level = 0, sort direction = Ascending
Sorted column: id = 'Column3', index = 2, visible index = 2, sort level = 1, sort direction = Descending
Columns count: 3
Sorted columns count: 0
