Flex :: Trigger An ItemEditEnd Event Within The ItemEditor
Sep 29, 2010
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
[URL]
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 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?

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 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"/>

Consider the following mx:Button:<mx:Button click="doSomething()" id="myButton"/>Is there some way to programmatically emulate the user clicking the button?One obvious way to do it would simply be to call doSomething() which would give the same end result as clicking the button. But I'm specifically looking for ways to emulate the click -- that is something along the lines of myButton.click() (if that should have existed).

Within a specific canvas, I would like a user to be able to press a combination of keys which will trigger an event.(a bit like a cheat in an old megadrive game). Not sure where to start though. Anyone know if it is possible and if so could you give me a clue with how to start?

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"

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?

Following is the sample code. While I start editing either in optionId column or option column, the other rows of the same column are also get affected and reflecting the same value. But when I am editing in other columns it is working fine... Don't know the reason.

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.

I'm trying to trigger this page turn event without having to click the page. I want it to go based on a timer event, where lets say after 30 seconds it turns the page. Unfortunately this is all in AS2, so I'm having trouble figuring out the correct way to go about doing this. function is called startFlip, and I need it to be enabled at 30 seconds instead of an on press function from the page button I originally had.
