Syntax

C#
public bool Sortable { get; set; }
Visual Basic
Public Property Sortable As Boolean

property bool Sortable {
	bool get ();
	void set (bool value);
}
F#
member Sortable : bool with get, set

Property Value

Type: Boolean
true if sortable; otherwise, false.

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().

    header.Add(new Column("Column1"));

    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:
