Actionscript 3 :: Assign DataProvider To DataGrid Dynamically In Flex?
Jul 19, 2010
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 ?
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.
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:
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?
in Flex I have something like that: [code]and dg is ALWAYS pointing at DataGrid (even if dg1 has name DataGrid_test and dg2 = DataGrid_test2) and finally action is made on my first DataGrid (DataGrid_test).[code]and search still points at ColorColumn :/ My problem is really easy- I just want to pass to search different dataGrid on each state.But still I don't understand why it doesn't work. My search function uses algorhitm Boyer-Moor for searching through dataGrid.dataProvider for some text. If it find something then it is pushed into new array and after passing whole dataProvider I colorize rows with searched word.
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 am trying to use JSON decoded as a dataProvider, but no matter what I try I get errors such as the following: Error #1034: Type Coercion failed: cannot convert mx.collections::ArrayCollection@2a88ae01 to fl.data.DataProvider.
I want to change a list's item render with code like this: booklist.itemRenderer = BookItemRender; BookItemRender is a subclass of s:ItemRenderer. It report error: 1067: Implicit coercion of a value of type Class to an unrelated type How to correctly specify a itemRender in code?
xml values are stored in 'arr' array collection. depending on the length of the array stored, the below described components are created and assign those values to relevant components dynamically. For Example:
I am building a Flex application with ActionScript 3. Unfortunately I've hit a wall with this one...I would like to be able to apply an upSkin to my dynamically generated button like this:
//this theSkin variable is dynamic in my app, but for this example it's a simple string var theSkin:String = "http://www.mypicturedomain.com/images/myimage.gif"; var navBtn:Button = new Button(); navBtn.id = "thumb1";
[code]....
When I attempt this, I get this error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@3dac941 to Class.
How do I skin this button with my image dynamically? A couple of things to consider:The upSkin image must be remote. It can't be local.The button must be generated dynamically (it's in a for loop).
I made a basic text editor that lets users insert predefined strings into the document with button clicks. What I need to do now is let the user define their own buttons and string values. For example I have a button that inserts "Hello" into the text. The user may want to create a button that adds "Goodbye".To accomplish this I figured I would create a .txt file called buttons.txt or something. i would readutfbytee, loop through it to create the buttons. problem is I know what I want to do but not sure where to start
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.
1) Using datefield as item renderer in flex.I am dynamically creating datagrid and its columns. like
dataGridColumn=new DataGridColumn(); dataGridColumn.dataField="invoiceDTO.invoiceDate";// I read this value from XML dataGridColumn.editorDataField="selectedDate"; dataGridColumn.itemRenderer=new ClassFactory(DateFieldRenderer); dataGridColumn.rendererIsEditor=true;
But when UI is generated i get the error invoiceDTO.invoiceDate not found on the TestDTO
//Test DTO
public class TestDTO { public var invoiceDTO:InvoiceDTO; }
My objective is my dataField should be binded with datafield inside the datagrid.How can i do it in actionscript
2) I need to present combobox as item renderer. (same like case 1). But how can i assign dataprovider in the combobox which is present inside the datagrid.
I am trying to make a datagrid, that will dynamically add columns to it based on some condition. Now, I am able to add the columns, but I want the newly added column to have button using itemRenderer. I am unable to achieve this though. Getting this error on line 1
Can we change the width of the datagrid column dynamically by clicking on the border of the column in order to display the complete string which is too long to be displayed and needs to be scrolled ? If so, How ?
Also, how can we ensure that the column width changes dynamically based on the number of characters / length of string; since many a times the data is too long to be displayed. Can we set the column width to take the length of data into consideration before displaying onto the datagrid ?
I have a panel inside which I have a datagrid and a button. The functionality is that when I click the button, an row gets added to the data grid. I have described the pane height and width in %. But as the number of rows in the data grid increase, due to fixed panel height, a scroll bar appears in the data grid. But I want the panel height to increase dynamically as I increase the data grid rows.This is my flex code:
