Flex - Add Row To Flex DataGrid Without Changing DataProvider
Sep 30, 2010
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.
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'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);
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 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.
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.
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.
I need to be able to animate a LineChart based on the SeriesInterpolate data effect (I will have an Array of dataproiders). I want to have a "Play" button that will:
initialize the LineChart with the first dataprovider in the array start the animation and wait for the animation to finish before loading the second data provider repeat the process until all data providers in the Array are loaded
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 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?
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)
How can i change the color, when the user mouse over an item on datagrid or tilelist. Basically once the user mouse overs and once the user selects a file. How to change the default color to something else. The default is blue and i dont like it :)
It is very simple to retrieve data from a database and display it inside a DataGrid. However, what are the current practices to push the changes in the DataGrid back to the database? One can achieve this by inserting a lot of meta information, however, it is very tedious and not reusable.
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]..
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 am using a combobox to list the contents of a folder. With a button click I use that combobox.selectedItem to delete that folder. After I delete the data is still in the combobox. How do I go about refreshing that combobox?
I am trying to get the drop down list of combobox by using a php file. That php file returns an xml string which has been used as data provider for combobox.I followed this thread too but in vain.DetailsI have set the creationComplete attribute of mx:Application to init(). In the init() function i have sent the following HTTPService
I'm trying to set a combobox's dataprovider.I have 2 comboboxes: cb_div and cb_stores.For cb_div, I get to set the data provider correctly with an XML file.Cb_stores' dataprovider is to be set depending on the selected item of cb_div.First, here are my XML files.Data provider for cb_div:
