Flex :: Using An ArrayCollection To Populate Both A Datagrid And A ComboBox
Aug 11, 2010
I use this arrayCollection to populate a Flex 3 Datagrid. I'd also like to use this arrayCollection to populate a comboBox with the Name node.
In the arrayCollection, I've got the Name listed twice. I've got two rows in the Datagrid.
If I set the ComboBox's labelfield to Name, then the Name will be listed twice in the ComboBox menu. Is there a way to use this arrayCollection and have each Name listed only once in the comboBox?
I can always make another loop and array collection for the Name, but I was wondering if there were a better way.
var i:uint;
for (i=0; i<myArray.length; i++){
myDGArray = [
I am developing a panel in Photoshop with Flex and Extendscript. I am pretty close to getting this to work, but with my Flex skills I am having a little issue with the Array I am pulling in from the jsx file. The array is displayed fine in the alert box, but somewhere between my split and creating new collection something is wrong.
Here is my Flex
protected function loadData():void { var grabFolderNames:SyncRequestResult = CSXSInterface.instance.evalScript("labNames"); var list:String = grabFolderNames.data;
I have a data grid with an Combobox itemRenderer in it. What I have is a grid with a person id and person name (more stuff in grid but I am struggling with this). In the person name column I have an combobox with all the people on then system's names and id's. What I want to do is when I select a person in the combobox I want the combobox to populate the person name fields (which it does) but I also want to pull out the person id from the combobox and populate the person id column in the data grid as well.
URL...In this demo I have a Datagrid populated from a php script.I also have a ComboBox embeded in the datagrid. In this example I am reading the ComboBox data from an array within a ComboBox CellRenderer.The question I am posing is how to dynamically populate the embedded ComboBox's from a php script with data retrieved from a mySQL table.
I want to load data from a external XML file, using a HTTPService, and on the ResultEvent of the same HTTPService i want him to populate a ArrayCollection with the data from the XML.
I think a ArrayCollection is the ideal for this XML.
I'm trying to setup a DataGrid that contains a column of combo boxes. The values of the combo boxes are defined by data specific to that row. I cannot get this to work though, I'm asking for a solution to this, either fixing what I have below or a recommendation on a different way.One of the columns of my DataGrid has an object derived from a ComboBox for an ItemEditor. The itemEditor is set like this:
My goal is to create a generic function that selects a value in a combobox according to a value. (My comoBox holds arrayCollection as dataProvider.) The difficulty is infact to get a propertyname in runtime mode.
public function selectComboByLabel(combo:ComboBox , propetryName:String, value:String):void { var dp:ArrayCollection = combo.dataProvider as ArrayCollection; for (var i:int=0;i<dp.length;i++) { if (dp.getItemAt(i).propertyName==value) { combo.selectedIndex = i; return; }}}
The line if (dp.getItemAt(i).propertyName==value) is of course incorrect. It should be arther something like: dp.getItemAt(i).getPropertyByName(propertyName)
I am getting return type as array from PHP. When I populate in my datagrid, the values are not coming... var appSes:Array = event.result as Array dg.dataProvider = appSes;
I am getting the values, from PHP is there anything other than this i have to do. <local:CheckBoxDataGrid id="dg" allowMultipleSelection="true" x="118" y="142" width="507"> <local:columns> <mx:DataGridColumn dataField="firstName" headerText=" " width="20" sortable="false" itemRenderer="CheckBoxRenderer" > [Code] .....
I'm just starting to learn flex and AS3I'm trying to get information into a datagrid that originates from a mathmatical formula. For example if I have 100 and I subtract 5 from it and continue to do so until it reaches 0 so my grid would be something like:
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?
My first issue is that when my ArrayCollection only has one item, for some reason I cannot select that first item. The change function set on the mxml never gets called when I try to select that one item. If I set a prompt, it works. I know that the item is not already selected because when debugging, the selected item shows null. I do not want to use a prompt. I want the first item in the ArrayCollection to be selected automatically. So if there is only one item, I want the selected item to be that. FYI - I am using a labelFunction to format the data in the Array Collection. why I cannot select the first item or set the first item in the ArrayCollection to be the selected item?
My bigger issue is that when my Array Collection gets updated, my label function must not be refreshing because when I first open the dropdown, it has specfic data. When the Array Collection gets updated and I open the dropdown again, I see the old data in the dropdown, yet it doesn't exist anymore.
So let's say I have a ComboBox that has a datasource of an array collection of one state code and it's state name. Their is a labelFunction that puts a dash in between the state code and the state name. Their is no prompt, so the ComboBox would look like GA - Georgia and when you open the dropdown, that would be all that is there. I want that item to be selected automatically. why the old data shows up when opening the dropdown after the array collection was updated with new data?
<mx:ComboBox labelFunction="getFormattedNpaNxxCollectionList()" dataProvider="arrayColl" change="doSomething()"/> public function getFormattedNpaNxxCollectionList(item:Object):String { return StringUtil.substitute("{0} - {1}", item.stateCode, item.stateName); }
Is there a way to reverse the order of the items in a comboBox? I'd like to use index numbers to refer to items in the arrayCollection below. I want the newest content to appear first in the comboBox. But, if I add something above the first item then all of the index numbers will be off by one. If I could add a new item to the end of the arrayCollection, but have it appear first in the comboBox drop down that would solve a lot of problems.
linedataColl is an AC that contains 200+ of rows extract from CSV and in my design, I wish to additem into SuperDataCollection object by object but the only problem was I'm unable to see any data display in "S" which is a datagrid. What wrong with my code?
var superDataCollection:ArrayCollection = new ArrayCollection(); var dc:ArrayCollection = new ArrayCollection(); var di:Object = new Object();
I am trying to bind an ArrayCollection result coming in from the server to my DataGrid created dynamically in AS. The result data is not getting Displayed in the Grid. var dg:DataGrid = new DataGrid(); dg.width=650; dg.dataProvider=someArrayCollfromServer;
I am adding the dgColumn as runtime based on some data from a XML and it is the same as defined in below static format. But if I use the same code and create the DataGrid as a Flex Component as below, it works fine. <mx:DataGrid id="dg" width="100%" height="100%" dataProvider="{someArrayCollfromServer}"> <mx:columns> <mx:DataGridColumn dataField="Value" headerText="Value"/> <mx:DataGridColumn dataField="Code" headerText="Code" /> </mx:columns> </mx:DataGrid>
This works fine. Is there some functionality or implementation different as far as DataGrid is concerned in Flex and AS.
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
I've got a Flex 3 application with an HTTPService returning an Atom feed. I catch the result from it and store it in an arrayCollection which is then the provider of my Datagrid. I have no problem accessing the data from the "first-level" of my Array, but cannot go under it. Not very clear, so here is some code:
The "title" column shows the data correctly, but the status column is empty ! When I launch my app in debug mode, I can see that my notesArray has the correct format and I can access todo -> status with the value..
i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

here is the code for the set data function (itemRenderer is extending HBox):
override public function set data(value:Object):void { _data = value; if(data!=null)
Is there a way to make a Flex 3 Datagrid show only the first node of an arrayCollection, instead of showing all of the arrayCollection's data?[code]...
I'm using FlashBuilder 4 and trying to create a dropdownlist that populates a datagrid. The functionality is fine but my data is being chopped up too much. Currently every since "nepName" tag in my XML file is showing up in my dropdownlist (which makes for many duplicates of the same names) and only shows the data associated with that nepName tag. I want each nepName (by name ex. Barnegat Bay National Estuary Program) to display only once in my dropdownlist and populate my datadgrid with ALL the data in the XML file that is associated with that name
I have a data grid that has ComboBoxes in two of its columns.
What I need to do is get the values of those bombo boxes when a user highlights the row of the grid NOT when the user uses the comboBox. I understand how to pull the values out once the change handler is invoked on the comboBox, but I'm not seeing a way to get at the comboBoxes that belong to the currently highlighted gridRow.
I'm sure it's really straight forward, but I'm just not able to find any reference on how it's done.
I have a DataGrid with a ComboBox as an ItemRenderer for one of my columns. When the user selects a row, I want to get the ComboBox's selected value for the selected row.
EDIT: I should have mentioned that the dataField2_Array property in myData is actually an Array is the dataProvider for the ComboBox. Each object in myData could have completely different values in that Array so the ComboBox in each row of the DataGrid could have completely different options to pick from.Some sample code:
How can I filter a datagrid based on the value in the combo box? Can anyone show me some good examples on it?
In my application, I already filter a datagrid based on the text entered by the user. I check if the entered string matches the column entry of the datagrid and if a match is found,the filterFunction on the dataprovider is called.
searchCriteria is the comboBox,where I have the items, "ALL","HIGH"...I have two rows with value "high" and I get the Alert "yes" for two times only.. But in the data grid all the four rows are displayed.
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?
I'm trying to update a combobox/datagrid sorter that came from flex3 to a flex4 version but I keep getting an error that my newbie brain is not processing. The error is "1067: Implicit coercion of a value of type Array to an unrelated type mx.collections:IList."
