Namespace: Wisej.Web
Assembly: Wisej.Framework (3.5.0.0)
Represents a data grid control.
Initializes a new instance of the DataGridView class.
Initializes a new instance of the DataGridView class with a specified data source and an event handler for the CellClick event.
onCellClick
An Action delegate to handle the CellClick event. Can be null.
Initializes a new instance of the DataGridView class with a specified location and size.
Boolean: Returns or sets whether the DataGridView can automatically sort rows in the DataSource when the data is in an IList object. (Default: True)
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.
