System.Web.UI.WebControls Namespace DataGrid Class
Occurs when an item is created in the DataGrid control.
[ VB ]
Public Event ItemCreated As DataGridItemEventHandler
[ C# ]
public event DataGridItemEventHandler ItemCreated;
[ C++ ]
public: __event DataGridItemEventHandler* ItemCreated;
In [ JScript ], you can handle the events defined by a class, but you cannot define your own.
The DataGrid control is structurally composed of an assortment of rows called items. You can have up to seven different types of items in a DataGrid: normal and alternating data items, a header, a pager, a footer, the currently selected item, and the item that is currently being edited.
When any of these items are created, the DataGrid control fires an ItemCreated event, against which you can write an appropriate handler.
This event provides an opportunity to access each item before the page is finally sent to the client for display. After this event is raised, the item is then bound to data and the ItemDataBound event in turn is raised, after which the data item is nulled out and no longer available.
Information related to the ItemCreated event is passed via a DataGridItemEventArgs object to the method assigned to handle the event. The following DataGridItemEventArgs property provides information specific to this event.
The following example illustrates a way to handle the ItemCreated event of a DataGrid. In this case, the sample sets the style properties of the specified button type in a ButtonColumn, as each item is created.
The below snippet shows how to attach a handler for the event.
<asp:datagrid id = "myDataGrid" runat = "server" onItemCreated = "setButtonStyle" ... >
The below shows how the handler method is defined.
void setButtonStyle ( Object src, DataGridItemEventArgs e ) {
if ( e.Item.ItemType == ListItemType.Item ||
e.Item.ItemType == ListItemType.AlternatingItem ) {
TableCellCollection myCells = e.Item.Cells;
( ( Button ) myCells [ 3 ].Controls [ 0 ] ).CssClass = "add";
( ( Button ) myCells [ 4 ].Controls [ 0 ] ).CssClass = "remove";
}
}
