Flex :: ItemRenderer As A Field Of `data`?

May 27, 2009

I would like to let the data provided to a DataGrid decide how best it should be rendered (that is, let the data carry with it an object which will do the rendering).For example, by creating a "Renderable" interface, which has a 'renderer:IFactory' property, then used as below:

<mx:DataGrid x="0" y="0" width="100%" dataProvider="{myDataProvider}">
<mx:columns>
<mx:DataGridColumn headerText="Task" width="100"[code]....

But to do this, Renderable has to extend IEventDispatcher, which seems like a little much...I've also tried using:

itemRenderer="{(data as Renderable).getRenderer()}"

Which does nothing (in fact, the getRenderer method never gets called).Is there a better way to do this? Am I doing something fundamentally wrong?

Flex :: Data Passed From DataGridColumn.itemToLabel To DataGrid.itemRenderer.set(data)?

Dec 4, 2009

I have a DataGrid whose dataProvider is an Array of int Arrays (each with different lengths). Since each row has variable size (and I want to display all the data), I decided to extend DataGridColumn and overwrite the itemToLabel function to be able to display the data. The problem is that I also need to display the data differently depending on the int value.

I believe the only solution is to write an itemRenderer, but the only input the itemRenderer.set(data) function receives is the entire int Array. I believe I need either the exact string returned by itemToLabel or the column index of the cell the itemRenderer is for (to basically do the same parsing I implemented in itemToLabel).

Actionscript 3 :: Data Vs ListData In Flex ItemRenderer

Aug 2, 2011

I was wondering what the difference between data and listData in itemRenderers in flex. I have worked with data in all of my itemRenderers.

Basically I want to know when to use which, where each gets set and if I can use them together?

Note that I am asking from a Flex3 point of view.

Actionscript 3 :: Limit Flex Spark DataGrid ItemRenderer Data To Column

Feb 27, 2012

I've got a DataGrid in my mobile application (I know, I know but there's currently not other solution for this), that numeric values. Depending on the value of a cell, the text gets colored. My big issue is that this doesn't work very for more than about 5 rows of data. I reckon the issue is that the set text function (in which I format the color) can't keep up with the amount of cell changes and formats the text based on the last updated cell of the row.I thought about a column item renderer so that the renderer only gets the value for that column, and not the whole data of the row.

Just for reference, this is my current item renderer (again, this works fine for few rows, for 5+ of fast changing data, this doesn't work any more, cells get formatted even though their data hasn't changed).[code]I just double-checked and have to revert my previous statement. A single row works fine, the second row already messes up the color formatting though. It seems as if the datagrid somehow throws together the values.
Doing the color formatting in the set data method shows the exact same effect;[code]My assumption about the grid messing up the ItemRenderer's data seems to be correct.A simple trace in the set data method (trace("old: " + _oldVal + "new : " + value[column.dataField]);) revealed that somehow, values of the next grid row (in case there are 2) get used as well as _oldVal gets the old value of the next row.

Flex :: Differentiate Between A Data Provider Update And A Itemrender Being Recycled When Using A Custom Itemrenderer In A DataGroup?

Oct 18, 2010

How do I differentiate between a data provider update and a itemrender being recycled when using a custom itemrenderer in a DataGroup?I have overridden the set data function of the custom item renderer, but I have found that on making a change to the ArrayCollection used as the DataProvider some of the item renderers are not assigned the same object they had before the update. This has made it almost impossible for me to distinguish between a data update and an itemrender being recycled. Also, the data never seems to get set to a value = null, so that seems to be out as well.

I have managed to import and read a PDF using the CF Proxy for Actionscript: [URL]After all my trouble there, the precious form filed information that I was looking for was not there in the PDF info object.

Database :: Displaying Query Data In A TextInput Field In Flex?

Feb 12, 2010

I'm trying to display query data into multiple TextInput Fields in Flex.

<mx:TextInput id="stagInput" text="{acContacts}" width="170" x="120" y="74"/>

This is what I'm trying but all that displays is [object Object]

I think I need to define the database field I'm wanting to display, but I'm unsure how to do this as TextInput fields don't support dataField or labelField properties. Is there another property I don't know about? How do i go about fixing this?

Data Integration :: MySQL Data Into Dynamic Text Field Without Escape Sequence

I got a music portfolio web site running PHP, MySQL and Flash. There's a page showing all the artists my client worked for and when you click on a song title, this title is passed as a variable to a PHP page then to a Flash page. The Flash page contains an actionscript music player which then looks for the right audio file in the database and plays the song. Everything works great except for the dynamic text field which displays the song title. If the song title contains an apostrophe or a single quote, the Flash dynamic text field then shows the apostrophe.[code]

Flex :: Displaying List Of Flex Progressbar Using Itemrenderer?

Sep 25, 2010

I want to create a list of progress bars and update the list accordingly.I have group data in an Array as

<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....

The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as

<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>

Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").

Flex :: Navigate Within An ItemRenderer?

How can we navigate within an itemRenderer? For example, in Views we use the View.navigator (ViewNavigator) to push and pop views, there is no such feature in ItemRenderer.

Navigation within a View (Easy)

<s:Button label="Questionnaire" click="navigator.pushView(view.QuestionnaireCategory1View)"/>

Flex :: Add ItemRenderer On The Fly On Component?

Jun 21, 2011

I have a List which has TextInput as itemRenderers for all its items. Upon application launch the items are rendered in the TextInputs correctly. The data is being populated from an Array of Objects.

What I want is, after the data has been populated in the ItemRenderers, I want to have an additional item renderer (TextInput of course)...so that if the user wants to enter another item, he can put it in the additional textInput.

And I also want to add the additional itemRenderer each time the user has added a new item and taps ENTER on the newly added item.

Below is my itemRenderer, there is the clearTxt_enterHandler handler..but I wonder how to add another itemRenderer upon "Enter".

Flex :: Datagrid With RadioButtonGroup Itemrenderer

Aug 12, 2009

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?

Flex :: ColumnOrder With Formatter And ItemRenderer
