This property is checked during a Data Bind operation only if the Data Source ID property is null or empty. Hierarchical Data Bound Control Main) Gets sets ability to maintain view state of controls on page if their properties were modified while asynchronous postback of this control. Only current page is placed in the view state if paging is enabled, meaning the grid will be requesting new page anyway of data if the page is switched. However, you will need to provide an appropriate event handler with the implementation for these operations. The automatic updating, deleting, and selection functionalities are enabled when a button in a Button Field or Template Field column field, with a command name of "Edit", "Delete", and "Select", respectively, is clicked. The Grid View control can be bound to a data source control (such as the Sql Data Source control or Object Data Source control) or to any data source collection that implements the System. Note The Grid View control can provide support for sorting, updating, and deleting with other types of data sources. Each field is then rendered as a column in the Grid View control in the order that each field appears in the data source. List Note This control can be used to display user input, which might include malicious client script.
That applies to the paged grid as well, so if a page is switched the grid will query the data source twice: once for the current page and once for the new page. If the property is False the grid is requesting data from its data source on every post back. Hierarchical Data Bound Control Main) Turns on separation of data and view of the grid. Control Value Property("Selected Value")] public class Grid View : System. When this property is set, the data rows are displayed alternating between the Row Style settings and the Alternating Row Style settings.
