Flex :: DataGrid And Static DataProvider Attribute
Sep 9, 2010
I'm trying to get this code working:
<mx:DataGrid x="359" y="221" width="623" height="176">
<mx:dataProvider>
<fx:Object name="Garbage Collection" code="7777" hours="2"/>
<fx:Object name="Road Repair" code="8888" hours="6"/>
<fx:Object name="Lawn Maintenance" code="9999" hours="12"/>
[Code] .....
I even don't have the header text in my columns.
I'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);
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 am working on an aplication using flex,adobe air...i have a datagrid with a XML as my dataprovider...during the execution of program my XML is updated....after XMl is updated and saved my datagrid should also get update..I have used Dataprovidername.refresh() method but it is not working.
There are several ArrayCollections and DataGrid in my application. Number of ArrayCollections determined by the input data. How to create own dataprovider for each DataGrid column?
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 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)"
Im working at a DataGrid which has a custom itemRenderer with a checkbox and a Label inside. Im struggling adding the the values from a xml to the wright label dynamically... how can I make the connection from the datagrid's dataProvider (a xml doc) to the label and the checkbox? My itemRenderer loks a following:
i have a method with brings data of particular table, as given my parameter to that method,
now i want to fetch data from corresponding table and it too list, and send back flex and form dynamically Grid & add dataprovider dynamically as for its corresponded table colomns in flex side ?
Now i want this create a Datagrid in flex dynamically by using its design & master data table in action script i done everyting , my dataGrid had formed as for his master design,but data is not showing ?
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.
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 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.
The 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?
I 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.
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?
I'm using a custom component CheckBoxList DataGrid (http://blogs.adobe.com/aharui/2008/02/checkbox_selection_in_datagrid.html) and as dataProvider I have an ArrayCollection with items such this one:
name="item name" selected="true"
I would like the CheckBox list updated when the selected attribute is set to false or true in the data model.
It seems like a best practice in Flex/Actionscript to define static variables that define event names like so:
public class MyEvent extends Event { public static const EVENT_NAME:String = "eventName"; // Other stuff.. }
It's a great practice since the event name can change easily and not have to be modified throughout the code. So my question is: Is there any way to use this static const in my metadata event tag? I can't seem to do something like this:
Am I just ignorant of the proper syntax to do this, or is it impossible? Seems like it's just asking for hard to find bugs if someone decides to change the const since it is not strongly typed here.
recently, I research for the collection framework, and find LinkedSet(AS3Commons collection framework,it is a good opensource framework) written in ActionScript, but it can't use as dataProvider in ComboBox or DataGrid, because only implements ICollectionView can use as dataProvider. So I want to try if a class implements ICollectionView can work or not. I know Flex has build-in class implements ICollectionView, but I only want to define a class not use build-in class. The class as simple as possible.(can work is enough)
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.
What should I be using to pull information from either DataGrid or DataProvider Cells. I guess itemToLabel(), or getEditingData() doesnt work any more.
In a DataGrid, how can I force data() of all itemRenderers on visible rows to be called when I've made an update to the dataProvider.I'n the following the Grid isn't updated after pressing doSomething. If I have a large list the update is done when scrolling down and then back up again, or in the case of the TreeGrid i open/close a node.
I'm currently attempting at a little flash project where i have a movieclip travelling vertically downwards along the Y axis. When it hits a certain axis (in this instance, 500), I have a class written so that the movieclip then travels back upwards along the Y axis. I want the movieclip to change frame when it hits 500 along the Y axis (it's a movieclip of a bird flying towards the sea, and as it flies back up i want a fish in it's claws). I've tried looking into a method to do this, but nothing seems to work! I tried adding to following line of code into my class -
{ if(_y > 500){ enemy1.gotoAndStop (2); }
but it gives me an error stating my movieclip is not a static attribute, and i have no idea what that means. I've tried putting a variation of this code into frame 1 of the movieclip itself, but it just skips straight to frame 2 without taking notice of any code relating to the Y axis.
I am using an component, and currently have a dataProvider working that is anArrayCollection (have a separate question about how to make this an XML file... but I digress).Variable declaration looks like this:
[Bindable] private var _dpImageList : ArrayCollection = new ArrayCollection([ {"location" : "path/to/image1.jpg"},
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; }
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]..
