Flex :: Convert XML Data To Number Before Filling An AdvancedDataGrid
Jun 16, 2011
I import XML data in order to fill an AdvancedDataGrid (using Flex 4.5). This ADG is correctly filled with the data, columns display the right information etc. etc.
But there is a problem! Indeed, the 'Cost' data are imported as 'Strings' and that is why I cannot do the SUM... I just get a nice 0 as a result! I would like to convert these data into Numbers, so that the addition can be processed. This conversion has to be done before filling the ADG I think.
I already tried to implement a custom summaryOperation but was unlucky...
public function calculateSummary(data:Object, field:SummaryField2, rowData:Object):void
{
var dataField:String = field.dataField;
[Code]...
The Alert always displays a void message, the data are not transmitted to this function I think
There is another thing: the user can insert new data in the XML dynamically and that insertion has to update the SUM result.
I want to extend AdvancedDataGrid to show a Waterfall Chart in one of its columns.
To do that I already created custom cell render that shows bars as I need.
Now I have a little challenge: I have to pre-process data to show my Waterfall Chart properly. I have to do it before my grid is show. So, I assume that I have to extends AdvancedDataGrid and overwrite some methods.
I have an AdvancedDataGrid with a HierarchicalCollectionView as its dataProvider. When I view the grid with the dataset I'm working with, and click the header of the column I wish to sort on, everything works perfectly. It sorts it hierarchically exactly how I would expect it to.What I want to do now is have the grid already be sorted when it is shown to the user. Is there a way to do this programatically? I can't for the life of me figure out how to do this, and clearly it's possible since the AdvancedDataGrid has this built in.[code]This appears to do something as far as sorting goes, but it doesn't sort it in the same way as clicking the column header. "startDate" is a property of an object in theDataSource by the way.
I am trying to display grouped data in AdvancedDatagrid but the data does not show up. When I specify the dataprovider without the grouping collection I am able to see the data. Is there something wrong with this code?
The dataProvider for my grid contains several objects. Some of which have a Number value, and some Boolean values under field 'value' (other fields are used in other columns).I would like to be able to render differently for each data-type, i.e. have a checkBox for booleans, and a label for numbers. Furthermore, I would like to be able to edit these fields differently, unchecking the checkbox for booleans, and using a numericStepper for Numbers.
Just FYI, I decided to go with AdvancedDataGrid, to take advantage of the styleFunction property, nothing more..Tried to used spark-states, which didn't seem to work as I'm using an AdvancedDataGrid. I'm not sure what the problem was.
Following is the sample code. While I start editing either in optionId column or option column, the other rows of the same column are also get affected and reflecting the same value. But when I am editing in other columns it is working fine... Don't know the reason.
Is there some way in Flex where I can tell when all of the data has finished binding to my AdvancedDataGrid? I have a bunch of label functions that run and I need to a busy cursor while the grid gets populated. I then want to remove it when it's all done. And also fire another event.
I have an advanced datagrid, but I want users to allow to copy some lines they want. when I use the property editable they are allowed to select the text they need, but they also are allowed to edit this. How can I prevent that?
I want users to be able to select any text in the datagrid, but they are not allowed to change the value of the grid. They should only be allowed to select and copy (ctrl + c).
I need to insert a Box containing some text that appears between the grid header and main content and spans all the grid columns. I've been searching and experimenting (addChildAt()) but no luck so far. Is this possible to achieve?If not, is it possible to dynamically render the text in the header itself, below and spanning the column header text?
I am trying to convert an entry using a numeric stepper in flex into words to display in a textarea.i.e a user uses the stepper to enter "89" as a value and in the text area the words "Eighty nine" are displayed.After much searching i haven't found anything that helps - a few javascript functions but that is all.
I'm trying to map XML tags inside an external file to the cells in a data grid. The only thing on the stage of my movie is a data-grid component with an instance name of dg. The movie loads an XML file named list.xml. Here are the contents of list.xml
<?xml version="1.0"?> <table> <row>
[Code]...
However, when I test the movie, only the headings are correctly displayed. The rest of the grid is blank. I know the arrays for the names, prices, and quantities are full of data. I'm just not sure how to put their data into the grid.
I have a MovieClip which has a couple of text boxes embedded inside it. I'm trying to load data from an XML file and populate the text fields with this data. That's fine, all good. What I also need to do is create an instance of that MovieClip for each instance of a certain tag in the XML, and then load that instance of the MovieClip with the relevant information.
So, for this XML file (reduced to show only 2 CD entries):
It should be rather clear what I am trying to do via the following code:
Code: d100button.addEventListener(MouseEvent.MOUSE_DOWN, d100func); function d100func():void { x = 1;
[Code]....
I tried to create a function for detecting the last button click (and getting the label of that button to use inside the function), but I decided to make the functions much simpler to at least get the desired effect.
I am new beginner, is it possible the covert flex data grid to CSV file format with out use any backend (java,php ..) file?. Because I tried with out use bankend. is it convert or not?
I'm using the Halo AdvancedDataGrid component, in which the default itemEditor for each column is mx.controls.TextInput.
For example, the data provider is: [CODE][Bindable][code]............
If a String from the dataprovider Array is preceded by an asterisk - as is the case for banana in this example - the String needs to be surrounded by square brackets and be displayed in a grey colour.
I tried to do the following: [CODE]
A colleague told me about using the AdvancedDataGridColumn's labelFunction attribute. I tried that but was unable to do the following assignment (the id of the column is 'tag'):
I get error "Access of possibly undefined property htmlText through a reference with static type mx.core:IFactory.I tried to both explicitly extract the TextInput itemEditor (like I did for the override set data) AND use the labelFunction, but I couldn't get both to be in the correct scopes.
I have an arbitrary number of files that I need to load in an AIR app.I want to iterate through an array of File object and create and launch Loaders for each one's File.url.When they are done (event COMPLETED or IOErrorEvent.IO_ERROR), I want to stuff their data somewhere. If they fail, I want to make an exception report. I cannot find any way to reference the File object from the event listener (certainly not the IO_ERROR)The best way would be to create individual event handlers for each Launcher that had the File information "hard-coded" into it. At the very least, I could use the function itself as an index to a Dictionary:
foo(fileToLoad : File) : void { var theCompletedHandler : Function = {
[code]....
Can I use event.currentTaget and use the Loader instance as an index? Will that have any weird dependencies ?
I have a bounded object, created using primitives lines in Action Script- either an oval or a triangle. Is there any way I can fill the contents in a specific color
Just to clarify on this- the shape could be in two ways
a) drawing a isoceles triangle based on a variable apex angle
b) two curved lines to form a "lens"
I am not sure if I can use the fill function, as I am not drawing a inherently bounded shape- the closed nature is based on my calculations
I'm using Flex 4 and I need to render the data that resembles HTML Table with row span in a Flex component.My inclination was to use a DataGrid but I believe that rowSpan is not supported for that component. I looked at the AdvancedDataGrid but the user does not want to have a tree-structure in any of the columns. Looking to see if there are any hints/tips for modifying the DataGrid or AdvancedDataGrid to produce an "HTML Table with rowspan" look.
I have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
Is there any way to detect if AdvancedDataGrid itemClick event is actually caused by the user dragging? I'd like to take action on click, but ignore drag.
My user is using a colourpicker to select the colour. I then want to use that picked colour to change an objects colour via colour transform. But colourTransform wants an RGB version of the colour.
I need convert 1 number from dec to hex, use array char, 0123456789ABCDEF, don't use toString(16).
[Code].....
This example use Array, I can change my char, this example code convert RGB color from dec to hex, number bigger 255 can't use, convert 1 number as 1297569443 to hex 4D5756A3.
I have an AdvancedDatagrid, whose dataProvider is an ArrayCollection that contains 1 row of displayable stuff.Flex continues to display about 6 rows, the top one filled, the rest blank.I've set the rowCount="1", with no luck.
after multiple Selection in a advanced datagrid, I want to check if the clicked row, was already selected. Anyway my idea below (in the nested if clause I want to check if the newly clicked item's processing data is already in the added Array Collection) is not working, but I assume there must be a better way to differiante if an click was made on a already selected row.
model.processingData = out; if (model.selectedIndices.length > 1){ //check if item already added
I would like to add new row on the fly (runtime) to my AdvancedDataGrid.I can add it to the data model, but couldn't find a way to make the table render and show the new row.What i am seeking for is to create an effect of expandable item, where clicking on row will show "additional information" (like a drawer) and clicking on row expand button will reveal it's children.I saw examples of this for dataGrid (http:url...), but not for AdavancedDataGrid.Only way I found to do this is to add a new child and use openItem, but this cause the other children to be visible as well.
