C#

public class DataGridView : Control, ISupportInitialize, IWisejDataStore, IWisejHandler

VB.NET

Public Class DataGridView
    Inherits Control
    Implements ISupportInitialize, IWisejDataStore, IWisejHandler

Constructors

DataGridView()

Initializes a new instance of the DataGridView class.

Properties

AllowSortingDataSource

Boolean: Returns or sets whether the DataGridView can automatically sort rows in the DataSource when the data is in an IList object.

When the DataGridView is data-bound, sorting is delegated to the DataSource when it supports sorting (see SupportsSorting). Otherwise, if the data is in an IList object and AllowSortingDataSource is true, Wisej swaps the rows in the data source. This behavior is different than WinForms, where sorting of the data source is always delegated to the data source and is otherwise ignored. Setting AllowSortingDataSource to false reverts to the same behavior as in WinForms.
