I have an array collection as the dataprovider to a datagrid. When I change a value in the arraycollection, a particular row gets updated in the datagrid. I want to get the index of that particular row. How do I get it?
View 1 RepliesI have two datagrids:
- Division
- Members
Both have single columns. Selecting one item from Divsions datagrid should display members of that Division in the Members datagrid. But following code has some problem and Members of a particular division do not show up when respective Divsion is clicked.
Following are some snippets of the related code. Hope someone can spot an error in it.

I have a datagrid with an xmlListCollection bound to it:
<mx:DataGrid id="dgCompetente" includeIn="Competente" x="10" y="66" width="547" height="468"
change="dgCompetente_changeHandler(event)" dataProvider="{colCompetente}"
editable="false">

I want the selectedIndex to remain the same. So, if I delete item 2, the next in the list should be selected. The problem is that if I delete item 2, item 3 will be selected and I have no idea why.
I want to give an array index to array collection let say 205 when it is started is it possible to do so in flex or any alternate of this.actually I need to index the objects with a specific no, in 2D array collection
say
205 a c d g f d
268 s g h g f f
805 d g h h f f d
where integers are indexes and alphabets are object referenced by these integers
My Flex datagrid automatically scrolls to the top when I update the dataProvider (ArrayCollection). I do not want this to happen, but I still want all of the objects to update. I am developing a semi-real time dashboard for a customer's management system, that will update often. If it scrolls to the top every time it updates, it will be very difficult and frustrating to use.I've attempted to use the following techniques to prevent this, none have worked.
dataProvider = updatedDataProvider;
dataProvider.updateItem(dataProvider);
dataProvider.source = updatedDataProvider.source;
dataProvider.updateItem(dataProvider);
I've attempted to dispatch a mouse event to hold the vertical scrollbar in place, I've attempted to lock the vertical scrollbar position value in place (saving and reassigning)..
I am using the flex datagrid to allow the user to edit some data. My update process relies on a CollectionEvent of type update. Basically I catch this event package the values and update the database. However, if the user edits a cell then moves to edit a cell in the same row the value is updated but a collection event is not fired. Only when clicking out of the row the event is fired. Has anyone had experience with this. I have heard the datagrid is a little quirky is this one of those quirks or am I doing this all wrong?
View 1 RepliesI've added an eventListener to the COLLECTION_CHANGE event that is fired when the grid is finished resorting the items in its dataProvider, after the user clicks on a column header:MyType (myDataGrid.dataProvider).addEventListener(CollectionEvent.COLLECTION_CHANGE,onDataGridResort);

I have a main datagrid, and want to launch a window with another datagrid in it, bringing in a different dataprovider. However, when I do this it acts funnny, brings in some default datagrid information and then gives me an error when I try to set the dataprovider:"multiple initializers for property dataprovider. (note: 'dataprovider' is the default property of mx.controls.datagrid)"

I need to display DropDownLists in a column of a DataGrid in my Flex application. Here is what I am doing:
First, I have a item renderer function that creates a custom item renderer, and passes it a property that is an IList that will be used as the dataProvider of the dropDownList:
private function rendererFunction(item:Object):ClassFactory {
var itemRenderer:ClassFactory = new ClassFactory(AudActionDropDownIR);
itemRenderer.properties = {AudActionData: AudActionData};
[Code]....
First, how can I call the init function when the renderer is created? Second, when I set the column's itemRendererFunction="rendererFunction", the app will not launch, a white screen comes up. But when I set itemRenderer="components.AudActionDropDownIR", the app will launch, but of course there is no data in the dropdown list.
I have an array, crewPositionsAC that contains a list of position abreviatations - EP, PR, DR, WR, and so on. These positions are read in through an XML file each time my flex application loads. Also being populated from an XML is a project. Within a project, there are positions (a student assigned to a type of position listed within crewPositionsAC). These positions are not necessarily in the correct hierarchy order dictated by crewPositionsAC. I have all the positions within an ArrayCollection (positionsAC) with the following structure:
positionsAC (arrayCollection)
[0] = Array
[0] = startOffset
[1] = numDays
[code].....
Then, the user can click a button to add another position. When the "Add Crew Member" button is pressed, the user is presented with a list of possible positions to add. Currently, I simply add another array to positionsAC. This results in the recently added crew member to placed on the bottom of the list. I need to take positionsAC and reorder it based on it's [2] item (role) based on the hierarchy defined in the crewPositionsAC. crewPositionsAC has the following structure:
crewPositionsAC:
[0] = EP
[1] = PR
[2] = DR
[3] = WR
* continue until all possible position types are listed
I know AS3Commons-collection framework is a good one, but it can't use in ComboBox, recently.I try to use LinkedSet data structure to retrieve and store data in ComboBox, any one can help me?
View 1 RepliesThe flex DataGrid colums are arranged alphabetically by default. I need to order the DataGrid colums as per the order in its dataProvider. The dataprovider is the result of the HTTPService . And the number of columns is not known to us . The number of columns depends on the HTTPService result.

I have a flex datagrid. it is bound to an array collection. if the user sorts on column X it works fine. then, if the user causes the array collection to change, the datagrid forgets that it was sorted on column X.what do I need to do to preserve this sort preference so that the new array data will appear sorted by column X?
View 4 RepliesSomewhere a get data to a 2 dimensional array. Is there any clever way to transform the array to a datagrid dataprovider without make a "for" loop?
View 1 RepliesI am creating the standard "Click to add row" control but I really don't want to dirty the dataProvider with a "placeholder" since it is bound to the model and could end up in the database. Is there a way to add a row that isn't represented in the dataProvider? I started down the road of adding an item directly to listItems but then that needed an item in rowInfo and then that need a reference in rowMap.
View 3 RepliesI have an array collection of strings and integers (which I have displayed in a data grid) and I am wondering if it is possible to export the array collection into an html table? or even a text file for the user to download
I found some pages that had an export to .xls files but I want to stray away from that for now.
While making my choice b/n Array and Arraycollection I get confused why whould I use one and why not another. I have read the theory in langref but apart from that is there some general advantages/disadvantages of one over the another that you have learned from your experience.
View 4 RepliesI have a Array of Objects
var pp:Array=new Array()
pp.push([object,object2,object3,object4])
all the objects have Events, propertys, functions.....I will like change the position in the array, but not destroy de object.
I'm writing a multi-layered drawing app, and I want to be able to move the layers up and down. It's easy enough to change the objects in the display list and move the buttons, but in order for it to work continuously I need to be able to change the index of the button objects in the array so they are targeted properly by the function. Is there a way to do this in AS3?

Is it possible to dynamically show row index for DataGrid rows ?
I have a static ArrayCollection which is set to be DataGrid's data provider and I would like to always have row numbering for each populated row (e.g. in a column called "#").
It would be an easy question, but property 'selectable' is set to 'false' and therefore selectedItem is always null.
In each row I have 3 buttons. When I click a button, I need to extract data corresponding to clicked row.
I am performing a find operation in a datagrid on one of the columns. After I find the row containing the item, I make that as the selected index row, which highlights it. But now I also want to scroll the datagrid down or up (if the item is out of screen scope) to show that selected item automatically on this find operation.
