Flex :: Commit New Value From ItemEditor Before ItemEditEnd Event
Sep 7, 2009
I have a DataGrid, with itemEditor as NumericStepper in a few columns. When a value in the DataGrid is edited, I would like to update several values displayed on the screen, and so want to call a updateValues() function.First, I added this function to itemEditEnd event of the DataGrid, but the function is getting called before the new value is updated into the dataProvider and hence, the values I have in the function are the old values. Is there any other event that is fired after the values are updated into the dataProvider? or am I missing something?Second, I tried putting this function in the change event of each itemEditor (duh!), but then again, the change event is fired, but the values in the dataProvider are the old ones.Is there any way I can make the function updateValues() be called, every time a value is edited AND updated into the dataProvider, because there's where I am taking the values from?

This might be an easy one for you DataGrid experts out there. I following an example for adding rows to a DataGrid dynamically from within a row

My tweak that I am trying to acoomlish, is to have a custom itemEditor that is a form with two TextInputs and an OK button. For the life of me I can't get that button to trigger the DataGrid's itemEditEnd event where I have some processing before I call destroyItemEditor. I tried dispatching the event myself directly but got a strange error in DataGrid's updateDisplayList saying editedItemPosition was null (editedItemPosition.rowIndex).

I have editable grids which are 2-way binded to my model. What I want is to validate my data when user edits any cell before it get updated in model. I have applied my validation at ItemEditEnd handler, but, I want to apply validation in between itemEditBegin and itemEditEnd events.

I am working with flex's datagrid. I have a DataGridColumn defined as the following, where labelFunction would allow me to display a custom text. I am also using a itemEditEnd handler on the grid to manipulate the entered data for this column. The purpose is to take the user input and split it then store the result in different properties other than "fixedValue". My problem with this approach is that I can't find a way to prevent assignment to the fixedValue property (which doesn't exist).
And using event.preventDefault() in the itemEditEnd handler would stop other events from happening like changing the row from edit mode to the view mode. My question is that if there is other way to achieve the same thing, or a way to just prevent the assignment of the "dataField" data. I am using the dataField to identify the column I am editing. Leaving it null might not be an option.
<mx:DataGridColumn id="columnFixedCurrency" labelFunction="fixedCurrecy_labelFunc" dataField="fixedValue" headerText="Price"/>

I have a List component that has drop-in CheckBox itemEditor that also serves as the itemRenderer. It displays each item as a simple CheckBox with a label.
However, the itemEditEnd Event does not get triggered until I click on something outside of the List. I want it triggered once the CheckBox is checked or unchecked.
I was thinking of manually dispatching the ListEvent.ITEM_EDIT_END in a CLICK Event handler, but then the itemEditEnd Event would get dispatched twice. There's gotta be a better way to do this.

I have a list component and I have an item editor for the items in the list. I would like to have a button that the user clicks once they are done with their changes because I am having them edit multiple pieces of data in the editor and I would also like to validate the data before closing the editor as well. I just don't know what to do on the button's click event to make the item editor close and commit it's changes to the data provider.

My application has a tree with a custom item renderer, which depending on the type of data at a leaf uses different components as editors. In one case I am trying to use a datagrid so that the user can choose a row that meets his needs (several columns need to be displayed), ie. similar in concept to a ComboBox.To do this I have a function assigned to be the handler for 'itemEditBegin' (for the tree) in which I'm dynamically creating the datagrid, and then using the popup manager to display it as a (modal) popup. So far so good.
However, if you click anywhere (eg. scroll down button in the datagrid) the popup disappears because the itemEditEnd event is fired - why ?In another scenario, I have a DateField setup as the editor, and the user can click on the icon to bring up a DateChooser, scroll through the months, etc. I looked at the code behind this, and it is using a popup, seemingly in exactly the same way as my code !Here is the 'itemEditBegin' code:
dataGrid = new DataGrid();
dataGrid.dataProvider = mddTable.dataCollection;
dataGrid.editable = false;

My custom item editor opens a titlewindow (too much stuff to show in an inline editor) which obviously steal the focus, so I get a itemeditend event and the datagrid destroy the editor at the wrong (for me) time. I think to have to keep the itemeditor alive until the titlewindow job is done, but how? DataGridEvent reason is "other" and livedocs said preventDefault() can't help.

I'm trying to use the Spark DropDownList as itemEditor in an AdvancedDataGrid. Howerver, I've stumbled onto two issues:Clicking on a item in the DropDownList changes the selected row in the ADG. You can see this behavior by compiling the code from below and executing the following steps.The value changes from "A" to "C" and Row 3 is the selected row in the ADG. It looks like the mouse click in the DropDownList is also handled by the ADG itself which changes the selected row accordingly. I couldn't figure out a way to prevent this. The expected behavior would be that row 1 is still selected after the DropDownList has been closed.Clicking on the scrollbar of the DropDownList closes the DropDownList. (I just found the solution to this problem in the relatated questions while writing this: Scrollbars in dropdownlist inside DataGrid itemEditor not working)

When not editing the cell, it shows a centered date as plain text. When editing, it shows a DateField editor. The second example is exactly the same as far as I can tell, other than the fact that it is an AdvancedDataGridColumn. Using that code with an AdvancedDataGrid, when I go into edit mode I can see the text from the normal item renderer behind the DateField editor (between the text input and calendar icon).
Example 1:
<mx:DataGridColumn id="endColumn"
dataField="endDate"
headerText="End"

Is there anyway to create a custom item editor based on the dataField value? For example:

<mx:column>
<mx:DataGridColumn headerText="Component" editable="false" dataField="label"/>

I have a datagrid column as follows:
<mx:DataGridColumn
headerText="Description"
dataField="description"
editable="true"
editorXOffset="2" editorYOffset="2"
editorHeightOffset="20" editorWidthOffset="60"
itemEditor="com.jono.controls.DgItemEditor"
wordWrap="true"
/>
And a very simple DgItemEditor:
<?xml version="1.0" encoding="utf-8"?>
<mx:TextArea xmlns:mx="[URL]" wordWrap="true" backgroundColor="#FFFFFF" backgroundAlpha="1">
</mx:TextArea>
Basically, this allows for a small 'popup' when the user edits a cell in the datagrid, allowing for more space to type. The problem that I am having is that the datagrid gridlines show through the itemeditor - i.e. the itemeditor is transparent. Is there any way that I can force it to be opaque?

I have a DropDownList inside the itemEditor of my DataGrid. There are enough items in the DropDownList to justify scrollbars. You can see the scrollbars, and the mousewheel works fine. If you move the mouse over the scrollbars, they'll change appearance fine (mouseover is working). If you click on them, the DropDownList closes as if you'd clicked elsewhere in the data grid.
I've been experimenting with custom skins hoping to find a way to trap the mouse event, but have been unsuccessful.
FWIW, this is Flex4, as an AIR app.

this is not strict AS3 question, but I believe that is still the best place to ask since it's related to AS3 projects So I have FDT 4.4 and subclipse installed. SVN Is working fine, but I cannot assign 'commit' command to keyboard shourtcut. I am assigning it it as always Preferences->General->Keys->Commit (SVN) to different keboard combination and none of them is working, but when I right click on the project, open team menu, I can see assigned shourtcult right to commit command.

I hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler);
private function iconClickHandler(event:MouseEvent):void

I am trying to understand event propagation in Flex framework and have a following doubt on it:
Scenario: I have a built-in component DropDownList on change of which I want to create a custom event refreshPreview and want to propagate it to a custom component PictureComponent.
In the custom component's mxml, I have added the Metadata directive as follows to register a refreshPreview event with the compiler
<fx:Metadata>
[Event(name="refreshPreview", type="flash.events.Event")]
</fx:Metadata>
Layout Details: In my main mxml application I have laid out DropDownList and the custom component such that both are siblings (i.e. have a common indirect parent)
e.g.
<s:Group id="contentGroup">
<s:Group id="formGroup">
<s:Form x="11"
[Code]....
I am seeing that the refreshPreview event is not getting propagated to the custom component.
I doubt this is because the built-in component is a sibling of the target (where the event got generated) and not a parent. how to make refreshPreview event propagate to custom component?

This is NOT duplicate of my earlier post (its is slightly different)But this is similar issue with similar error but its not the same error The error I am getting now is below while dispatching the custom event from my custom component
TypeError: Error #1034: Type Coercion failed: cannot convert events::MapEvent@a74ab51 to flash.events.MouseEvent.
dispatchEvent(new MapEvent(MapEvent.CLICKED_ON_MAP));
Note: The error in my earlier post is giving below error message
Type Coercion failed: cannot convert flash.events::Event@81ecb79 to com.events.ShopEvent
The difference here are two things, the earlier error is while converting flash event to custom event and now this one is while converting custom event to flash event and secondly, I have no clue why it is trying to convert to the mouseevent where I am just dispatching my custom event with proper listeners.
This is my custome event
package events

import flash.events.Event;

I have a textfield in flex with a focusOut event on it. I can type in the box and in Firefox and Chrome when I click elsewhere on the page (outside the flash element) the focusOut event will be triggered. However in IE8, the texfield never loses focus when you click elsewhere on the page, outside the flash object. I've tried with focusManager.browserMode set to true and false with no difference (I believe that effects incoming focus anyway).
