Actionscript 3 :: ArrayCollection Of One Element As DataProvider
Jan 23, 2012
I use httpservice with object result to load data on dropdownlist. Some time the result is only one element. In this case, an error appear. I know that another solution is to e4x result format but I think that in this case it's longer.
I have a Datagrid with an ArrayCollection as DataProvider, the arrayCollection is partially generated by a remoteObject call, the dataprovider seems to works at least until I try to edit the field...By the RemoteObject I only receive an ArrayCollection with the field ip, but the datagrid looks for the fields ip, check and save...If I add/edit this new field it works, but only under particular condition
This code always work in the 3 points, so at the end of the call the ArrayCollection is always filled with the new values, but the datagrid refresh the items only in point #1 and #2.
I create a DataGrid to display a XML file and I have used XMLListCollection before. But when I modified the XML file, the DataGrid does NOT refresh itself automatically. I googled for this problem and found these links: refresh flex dataGrid
Here am getting array of groups(groupName,GroupID each row ) from a RemoteObject and displaying in a ComboBox. I am selecting the groups with selectedIndex as 0,1,2,3, but I want my groupIDs of correspoding groupnames,which am bringing to client side.
How can I get actual the groupId of the selected group?
I have a list (LIST#1) of artists: 2Pac Adele Amerie Beyonce Jason Aldean Shakira The Trews
I also have a list (LIST#2) that has the values #,A-Z - how would I create an alphabet jump? So If a user clicked on "A" in LIST#2 that would automatically scroll to "Adele" at the top of LIST#1 - not filter so he/she could scroll up to view 2Pac or down to view The Tews if they were not in the view yet. Its a standard Flex Spark List with an ArrayCollection as the dataProvider - the artist field is called: "title" along with a unique id field that is not visible to the user.
private function alphabet_listChange(evt:IndexChangeEvent) : void { var letter:String; letter = evt.currentTarget.selectedItems[0].toString(); trace(currentDictionary[letter]); ui_lstLibraryList.ensureIndexIsVisible(currentDictionary[letter]); [Code] ......
I know how to display data in a List control using dataProvider but what about control that don't have dataProvider e.g. TextInput, Label contorl?[code]Try to use {dp.ID} and {dp.getItemAt(0).ID} on TextInput but nothing being display?How to make TextInput id=" first Name" able to display the SQL data?
Objective:I would like to pass Skins to an itemRenderer (which is a Button) of a List, and be able to skin every button in that List.This is what I have:
I am working on a Flex AdvancedDataGrid with a flat ArrayCollection dataProvider. The requirement is that when the root nodes is closed, the root row should show a subtotal data and when the root nodes is opened, not show the subtotal data.
I am using a Repeater in an Accordian which does not appear to see a single element in userArray. If I add another entry to userArray then the Repeater works fine.
private function currUsersServiceHandler(event:ResultEvent):void{ if (event.result.currentUsers != null) { if (event.result.currentUsers.user is ArrayCollection) // if more than one elements are present {
[code]....
Edit:There is another thing I have just noticed i.e. that the accordian does show a single tab (when Array has a single element) but it's not labeled with the first name which I am setting. If I enter another user, two tabs appear and both are labeled with names I am setting. The first tab appears labeled too then.
how do i find out the number of properties in any element of the ArrayCollection? The structure of the ArrayCollection wud be something like:
var arrColl:ArrayCollection = new ArrayCollection([{column1Data:"someData",column2Data:"someData"},{column1Data:"someData",column2Data:"someData",column3Data:"someData"},
I'm new to Flex and am using TileList bound to an ArrayCollection. The array collection is empty at load time, and then updates with the results from am HTTPService call. The problem is that the item renderers aren't being rendered as expected, I'm guessing because there was no data when they were first rendered at load time. Here's simplified example:
I have a advanced datagrid and populating some data by using arraycollection. And i am filtering the arraycollection, the arraycollection index got changed.
I know that there is no such function as getElementByName in Flex but I also now that you can do this["object_id"] to get the element of the application u're in.What about getting an element inside another element?I've tried making element["id"] ? But in my try-catch it always runs the "catch" part..how do I get an element inside another element just having it's id in dynamically created string form?
I have flash where there is a link for song download. And, at the bottom of the flash I've a count, loaded thorugh flash vars which should increment everytime donload button is hit. Please let me know what approach should i take to do that. can i call a Java method on donload button which will insert a row in the table and and then get the count and render it to the count variable in my flash?
May be this extremely confusing. Here is a very similar example on how it is done. This is actually very similar to what i want to do. [URL] on this link there is count below which increments you hit the download button.
I've built a rather robust tooltip class recently that attaches and draws a single tooltip sprite to the root, then uses MOUSE_OVER to detect when it is over a tooltippable object, and shows the appropriate tooltip text. At the moment, I'm ensuring that any elements in my application which wants to take advantage of showing tooltips implement the ITooltippable interface, and expose a public getter, get tooltip().
Basically I have 14 text boxes, each box draws its content from an external txt file. Next to each text box is a button. I want the button to be either visible=true or visible=false depending on weather or not the text box has content or is "undefined" Here is what I have so far, and it's not working:[code] I would like a FOR loop to just run through the variables and check to see if any of them are undefined. if it is, then make the correct send button invisible.
this["nodeValue"+i] = new TextField(); (surely in dynamic class )
then I want to change instance name of that element.when I trace this["nodeValue"+i].name.I got a different name for that element ! f ex : instance8 .how can I get "nodeValue"+i from my element and change that .is it read only ? I want to swap tow element's instance name !
for example : this["nodeValue"+i] to this["nodeValue"+i+1]
I am having a problem with my drop traget. I have the ability to drop and duplicate multiple objects on a stage. I have a clip set up (canvas) which is used for if someone drops objects onto this it duplicates the dragged clip.
However the problem I am having is that if someone tries to drop an element on top of an already drop/duplicated element, it wont duplicate the new clip. Its like it thinks that the dragged clip is not over the canvas.
I have a datagrid with dataProvider property set in MXML as: dataProvider="{pagedResult.lastResult}" How do I set the dataprovider in actionscript? I have: protected function getResult (event:FlexEvent):void { pagedResult.token = mydata.paged(); adg1.dataProvider = pagedResult.lastResult; }
Normally in Flex you use a collection like ArrayCollection as the dataprovider for components. I often have data stored as a dictionary whose values I would like to use as a dataprovider.
When setting an arrayCollection as a dataProvider to a comboBox programmatically,if the arrayCollection has just one element,i need to do a small validation[code]..
I'm having some trouble when using objects in an array for my dataprovider.
Here's the code I'm using...
Code: for(var i:int=0;i<getLength(obj.responseData.results);i++) { dpData[i] = new Array(); dpData[i].push({Title: obj.responseData.results[i].titleNoFormatting});
[Code]...
The reason I'm doing it this way is so that I get to set the name of the columns. If I let the object define these, I get things like streetAddress instead of Address, which isn't huge, but still not what I'm after.
When I do it this way though, I just get 0, 1, 2, 3, 4, 5 for the column headers.
So, needless to say, I'm quite confused about what I'm supposed to do to get these objects to show up as strings in the datagrid.
I've tried String(), but that still just gives me the object like before.
If I open a new Flash (AS3) file in Flash CS3 Professional and try to import DataProvider (import fl.data.DataProvider;), I consistantly receive a compiler error (1172: Definition fl.data:DataProvider could not be found).
