The DataGridEvent.ITEM_EDIT_BEGIN constant defines the value of the
type
property of the event object for a
itemEditBegin
event, which indicates that an
item is ready to be edited.
The default listener for this event performs the following actions:
- Creates an item editor object by using a call to the
createItemEditor()
method. - Copies the
data
property from the item to the editor. By default, the item editor object is an instance of the TextInput control. You use theitemEditor
property of the list control to specify a custom item editor class. - Set the
itemEditorInstance
property of the list control to reference the item editor instance.
You can write an event listener for this event to modify the data passed to the item editor. For example, you might modify the data, its format, or other information used by the item editor.
You can also create an event listener to specify the item editor used to edit the item. For example, you might have two different item editors. Within the event listener you can examine the data to be edited or other information, and open the appropriate item editor by doing the following:
- Call
preventDefault()
to stop Flex from calling thecreateItemEditor()
method as part of the default event listener. - Set the
itemEditor
property to the appropriate editor. - Call the
createItemEditor()
method.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the
item's column in the DataGrid object's columns array. |

localX | NaN |
reason | null |
rowIndex | The zero-based index of the item in the data provider. |
target | The Object that dispatched the event;

언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
The DataGridEvent.ITEM__EDIT_BEGINNING constant defines the value of the
type
property of the event object for a
itemEditBeginning
event, which indicates that the user has
prepared to edit an item, for example, by releasing the mouse button
over the item.
The default listener for this event sets the DataGrid.editedItemPosition
property to the item that has focus, which starts the item editing session.
You typically write your own event listener for this event to
disallow editing of a specific item or items.
Calling the preventDefault()
method from within your own
event listener for this event prevents the default listener from executing.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the
item's column in the DataGrid object's columns array. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
dataField | The name of the field or property in the data associated with the item's column. |
itemRenderer | The item renderer for the item that will be edited. This property is null if this event is generated by keyboard, as the item to be edited may be off-screen. |
localX | NaN |
reason | null |
rowIndex | The zero-based index of the item in the data provider. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |

ITEM_EDIT_END | 상수 |
public static const ITEM_EDIT_END:String = "itemEditEnd"
언어 버전: | ActionScript 3.0 |
제품 버전: | Flex 3 |
런타임 버전: | Flash Player 9, AIR 1.1 |
The DataGridEvent.ITEM_EDIT_END constant defines the value of the
type
property of the event object for a
itemEditEnd
event, which indicates that an edit
session is ending.
The list components have a default handler for this event that copies the data from the item editor to the data provider of the list control. The default event listener performs the following actions:
- Uses the
editorDataField
property of the DataGridColumn associated with this event to determine the property of the item editor containing the new data and updates the data provider item with that new data. Since the default item editor is the TextInput control, the default value of theeditorDataField
property is"text"
, to specify that thetext
property of the TextInput contains the new item data. - Calls the
destroyItemEditor()
method to close the item editor.
You typically write an event listener for this event to perform the following actions:
- In your event listener, you can modify the data returned by the editor
to the list component. For example, you can reformat the data before returning
it to the list control. By default, an item editor can only return a single value.
You must write an event listener for the
itemEditEnd
event if you want to return multiple values. - In your event listener, you can examine the data entered into the item editor.
If the data is incorrect, you can call the
preventDefault()
method to stop Flex from passing the new data back to the list control and from closing the editor.
The properties of the event object have the following values:
Property | Value |
---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the
item's column in the DataGrid object's columns array. |
currentTarget | The Object that defines the
event listener that handles the event. For example, if you use
myButton.addEventListener() to register an event listener,
myButton is the value of the currentTarget . |
dataField | The name of the field or property in the data associated with the item's column. |
itemRenderer | The item renderer for the item that is being edited. |
localX | NaN |
reason | A constant defining the reason for the event.
The value must be a member of the DataGridEventReason class. |
rowIndex | The zero-based index of the item in the data provider. |
target | The Object that dispatched the event;
it is not always the Object listening for the event.
Use the currentTarget property to always access the
Object listening for the event. |
type | DataGridEvent.ITEM_EDIT_END |
ITEM_EDITOR_CREATE | 상수 |
public static const ITEM_EDITOR_CREATE:String = "itemEditorCreate"
The DataGridEvent.ITEM_EDITOR_CREATE constant defines the value of the
type
property of the event object for a
itemEditorCreate
event, which indicates that the datagrid has
completed the creation of the item editor.
There is no default listener for this event.
You typically write your own event listener for this event to allow
custom modifications to the itemEditor
before the user can
begin editing.

Property | Value |
---|---|
bubbles | false |
cancelable | true |
columnIndex | The zero-based index of the
