Image item renderer issue

Hi all,
Yesterday I found a soultion to display my image in my datagrid column. Now the issue is that if i leave the screen and come back to my screen the images move one space like the row index is adding one count, it's not validating my if statement.
Any ideas?
Thanks

Renderers get recycled. CreationComplete is rarely the event to use. See

Image in item renderer issue for List Components

Hello,
I have an issue when I use an item renderer with an image in
it. This happens when I do this with a List or TileList component
that has enough items to create a scroll bar. What happens is the
images load fine, then I scroll down and the other items and their
images start appearing, but then the first and last images start
loading the wrong image. I'll scroll back up and the first item now
has a different image, and when I scroll back down, the last images
changes too.
Has anyone had this problem with image itemrenderers in List
components?
Thanks for any help.

The creationComplete event is called ONCE and that's it. But
each time an itemRenderer is recycled it will have its data
property reset with new a new record from the dataProvider. Thus
overriding the set data function lets you inspect the data and do
what you want with it.
Data binding in MXML <mx:Image source="{data.image}" />
is set up by the Flex compiler. When the data property is reset it
will trigger the data binding notifications. The Flex
compiler-generated code will intercept that and update the Image
source property.
If you use MXML, then use data binding. If you write your
itemRenderer in ActionScript, override the set data
function.

Item renderer issue

Hi,
I have a comboBox as item renderer in my datagrid (comboBox item renderer code bellow).
1. How can I remove the first blank item? My comboBox arrayCollection doesn't have 0 item.
2. If I come back to the cell that it was already selected with a value from my comboBox, how can I set the selected item of my comboBox to be the same as the previus value? If I leave the comboBox without selection it will be blank as the 0 element.
Please help.
Thanks
Johnny

Custom Item Renderer Issue for List

Hi,
I have a List that uses a custom renderer that contains a
combo box and a checkbox.
If i define the data provider inline in MXML both the
combobox and the checkbox render values correctly.
However, if I switch the dataprovider to an AS 3.0
ArrayCollection using same name/value pairs, the checkbox renders
properly but the combo box doesn't show text values. What is weird
is that if I trace the data, the value is accessible but it won't
show in combo.text of control.
Any ideas?

The creationComplete event is called ONCE and that's it. But
each time an itemRenderer is recycled it will have its data
property reset with new a new record from the dataProvider. Thus
overriding the set data function lets you inspect the data and do

Datagrid Checkbox item renderer Issue.

Hi There
Recently I faced a requirement to have a checkbox inside a datagrid where I need to develop a music module with playlist management for ADOBE AIR based application.
For this I have searched and found a source to use Datagrid and Checkbox components which overrides some inbuild methods to give the required result..
But Finally I ended with one strange issue
When the check box is placed in the datagrid at 0 column index it works firne but if we place at any index ( I need it to be last colum ) the checkbox is not updating the display.
Source Flex Air project attached.
From the sample... While clicking on a row the left column checkbox is getting updated but Right remains same... when you scroll the Datagrid then the checkboxes are getting update when they are redrawn. I didn't found where to call the redraw for the right checkbox column.
Cany any one faced this strange issue. and found any solution ?????
If the Logic what I am following for a Playlist module is not good one then suggest if you guys know any other mechanism to develop a playlist management with datagrid and Checkboxes.

Dynamic Item Renderer

Hello everyone,
I used Catalyst to design my interaction and navigation and then use Flash Builder to add all my logic. Everything works as expected but i have one issue regarding my item renderer data list.
Here is my issue : i set up an itemRenderer for a dynamic calendar filled by a database.
Every schedule contain one to four workshops (data.ws, data.ws2. data.ws3 data.ws4) and are separated by a static bar (footerGroup)
So, i am trying (since days now) to make this separate bar dynamic so there are no blank gap between repeated two schedules if there are less than 4 workshops.
I reckon i need to code an actionscript "if statement" for the bar to move its Y according to workshops.
Thanks for your help and guidance guys,
i have a designer background and have some hard time to develop some special features
End-user view without the dynamic bar:
here's my Flash Builder code :

Wouldn't I then just get one image? Whereas what I want is if
the value = 1, display 1 image. If the value = 2, display 2 images.
Thus creating a bar of images.
Im actually having trouble adding multiple images to the HBox
in the itemRenderer.

Datagrid item renderer delete button

I have a datagrid with an item renderer. In the item renderer
is a delete button img. Onclick it will remove the item from the
datagrid with the exception of the first item. I am using outer
document to call my function but when I do I get an error that says
Attempt access of inaccessible method deleteContact through a
reference with static type myTitleWindowContact?
private function deleteContact(event:Event,data:*):void{
if (contactData.selectedIndex >= 1) {
caseVO.acCont.removeItemAt(contactData.selectedIndex);

That fixed that issue Thanks so much! One other question
though. Is it possible to have my delete button appear on all items
in the datagrid except for the first item??

Problem currently is since lbl_initialize() function is called on creationComplete of Vbox, output displayed is not expected and when ever i navigate to grid page output gets changed and it is not proper.
I wanted to use text ,lbl, in my main.mxml so that i can assign the value when i am setting data provider.
Please help!!!

Thanks for your reply.. overriding set data in fact is a better approach and my half problem is solved but i am still facing some issues. Please find my code below:
<mx:DataGridColumn headerText="Messages" dataField="mymsg" wordWrap="true" resizable="true"
 >
 <mx:itemRenderer>
 <mx:Component>
 <mx:VBox verticalScrollPolicy="off" >

 <mx:Spacer height="50%"/>

 <![CDATA[
 import mx.core.Application;
 import mx.controls.Alert;
 public var tempsecuname:String;
 public var tempmsg:String="";
 override public function set data( value:Object ) : void {
 super.data = value;
 lbl.htmlText="<a href='event:data.uname'>"+data.uname+"</a>"+tempmsg;
 if(data.datetime>Application.application.lastlogout)
 Alert.show(Application.application.lastlogout);
 lbl.setStyle("fontWeight","bold");
 private function lbl_link(evt:TextEvent):void {
 ]]>
 </mx:Script>
 </mx:VBox>
 </mx:Component>
 </mx:itemRenderer>
 </mx:DataGridColumn>
Now my text is coming properly with link like how i wanted. I have added here another functionality where I am checking the last logouttime of user and the msg time and if msgtime is greater than last logout time then i am showing it in bold.
override public function set data( value:Object ) : void {
 super.data = value;
 lbl.htmlText="<a href='event:data.uname'>"+data.uname+"</a>"+tempmsg;
 if(data.datetime>Application.application.lastlogout)
 Alert.show(Application.application.lastlogout);
 lbl.setStyle("fontWeight","bold");
First time is shows properly but if i scroll then some random row is also appearing in bold, also when ever this set data function is getting called some random rows are coming in bold.
Please let me know your input

ColumnChart - 3D Item Renderer problem

I'm building a 3D column chart and am finding that I need to
draw the columns in a specific order other than the default, which
appears to be by series.
Things go just fine until the z-order depth is greater than
the distance between the series. Once that occurs, the potential
exists for things to go south.
To demonstrate the issue, I've put a few screenshots here:
3D Column Chart
Images
My question: Is there a way to define, or otherwise take over
the drawing order of the ColumnSeriesItems? I want to draw the
columns in the order they appear from left to right, but Flex seems
to want to draw by order of series - first Series1, then Series2,
then Series3, etc.
I'm looking through the Framework source code, but I haven't
found a way around this - yet. Of course, if there's another
approach, like using some clipping method I'm not aware of, etc,
please feel free to clue me in.
Thanks in advance to anyone with useful info.

Thanx for reply.But this is not what i am looking for.I need
to apply different colors for each bars.I am generating charts
dynamically.The item renderer is working fine.But at specific
condition the item renderer shold ne removed from the chart series

Is that a webkit rendering issue in Safari 5.1?

I add my voice to rendering issues encountered in Safari 5.1, here they are:
1) Fonts look pixelated on some websites. Here's an example drawn from weebly.
The font used here is OFL Sorts Mill Goudy, so I guess there must be a font rendering engine in weebly that allows non web safe fonts to be displayed properly. That works fine in Firefox 5 & 6, and until recently on Safari 5. Chrome 12 has exactly the same issue as Safari 5.1, so it could be a general rendering issue in webkit.
2) Videos on Vimeo show now a black rectangle instead of the video.
3) The "Insert image" feature in this forum takes forever to load, displaying a white rectangle during several seconds. Same issue with the Evernote clip bookmarklet.
Hope these issues will be fixed soon, any help is appreciated if something can be changed in Safari settings.
Note: resetting Safari (including cleaning cache) doesn't solve the described problems. I'm running Snow Leopard 10.6.8 on Mac Pro Quad 2.8 Ghz.

Thanks for helping diagnose this.
However, my testing indicates that this is not a bug with border-collapse: collapse. Here is why:
If I change the value of border-collapse to "separate" and add "border-spacing: 0", the bug remains. To try this, request http://www.panlex.org/cgi-bin/plxu28-bug2.cgi .
If I leave the value of border-collapse unchanged but change the button elements in the cells to plain text, the bug disappears. To try this, request http://www.panlex.org/cgi-bin/plxu28-bug1.cgi .
On the basis of this testing, it would seem to me that the bug is dependent on the button elements and independent of the border-collapse CSS attribute.
This doesn't explain, however, why you have found border-collapse: collapse producing slow results with other large tables and it doesn't do so with my table in http://www.panlex.org/cgi-bin/plxu28-bug1.cgi . It also doesn't explain why you saw the bug disappear when you changed border-collapse on my page but I didn't see it disappear.
Any further diagnostic help would be welcome.

Using a bitmap object as a item renderer in a datagrid

I have a UIComponent grabbed has a bitmap, and stored in an
array collection.
I want to display a thumbnail in a datagrid, I can make a
itemRenderer for an image with a local or remote file as a source.
But how do I use the bitmap in the array collection in an item
renderer.
Thanks

Adobe Acrobat X Pro Ver. 10.1.7 rendering issues

Hello
I have rendering issues with Acrobat X Pro Ver 10.1.7.
When I zoom in to 100% and use the hand tool to move the image around, it moves about 1 inch then it freezes for 3-4 seconds, then I can move it again. This happens at all zoom %, but it gets worse as I zoom in further.
This gets even worse if I add text callouts and text boxes.
Windows reports the size of the .pdf document at about 700 Kilobytes.
I played with the Preferences - 3D & Multimedia - Rendeiring settings, etc. to no avail.
I have 64 bit Windows 7 Enterprise on a DELL Precision M4500-I 1.6GHZ CORE I7 QUAD CORE laptop with 8 GB of RAM and a NVIDIA QUADRO FX 1800M with 1 GB of RAM. I also played with the NVIDIA Control Panel settings to no avail.
This gets very anoying, I need to get work done on these .pdf files and this issue slows me down, and irritates the hell out of me.
I thought my laptop is underpowered, but at this point I tend to believe it is an Acrobat issue.
Please, any input appreciated.
Thanks

When to use Drop In Item renderer and InLine Item Renderers ??

Hi ,
I am getting confused in where to use Inline ItemRenderer and DropIn Item Renderer .
What i feel is that DROP in Item Renderer are easy to use , and those can satisfy any requirements .
What i read from tutorilas that we cant use Drop In because they say , The only drawback to using drop in is that them is that you cannot configure them
Please help me .

Hi Kiran,
Here is the detailed explanation you needed:
You can also refer the link below:
http://blog.flexdevelopers.com/2009/02/flex-basics-item-renderers.html
Drop-In Item Renderers
Drop-In Item Renderers are generic in nature and don't rely on specific data fields to render data. This allows them to be used with a wide range of data sets, hence, the term “drop-in”. Drop-In Item Renderers can be “dropped-in” to any list-based control regardless of the dataprovider’s data properties.
In our previous example, the employee photo property requires use of a custom Item Renderer to render properly in the UI. In this scenario the Image component satisfies our rendering needs out of the box. Implemented as a Drop-In Item Renderer, the Image component takes any data property regardless of name and uses it as the Image component's source property value. Assuming our employee photo property contains a valid image path, the Image Drop-In Item Renderer will work perfectly and resolve the image path as an image in the UI.

<mx:DataGridColumn dataField="photo"
 headerText="Employee Photo"
 itemRenderer="mx.controls.Image"/>
Drop-In Item Renderers are simple and easy to use and satisfy specific use cases nicely. However, they provide no flexibility whatsoever. If your needs are not satisfied by a Drop-In Item Renderer, you must create your own Item Renderer as an inline component or an external component.
Inline Item Renderers
Generally used for simple item rendering requiring minimal customization, inline Item Renderers are defined as a component nested within the MXML of your list-based control.
It is important to note that Item Renderers nested within the itemrender property of a list-based control occupy a different scope than the list-based control. Any attempt to reference members (properties or methods) of the parent component from the nested Item Renderer component will result in a compile-time error. However, references to the members of the parent component can be achieved by utilizing the outerDocument object.
<mx:DataGrid id="myGrid" dataProvider="{gridData}">
 <mx:columns>
 <mx:DataGridColumn headerText="Show Relevance">
 <mx:itemRenderer>
 <mx:Component>
 <mx:Image source="{'assets/images/indicator_' + data.showRelevance + '.png'}"
 toolTip="{(data.showRelevance == 1) ? 'On' : 'Off'}"
 click="outerDocument.toggle()" />
 </mx:Component>
 </mx:itemRenderer>
 </mx:DataGridColumn>
 </mx:columns>
</mx:DataGrid>
Remember, rules of encapsulation still apply. Mark all properties or methods public if you want them accessible by your inline Item Renderer. In the previous example, the toggle() method must have a public access modifier to expose itself to the inline Item Renderer.
public function toggle():void
Inline Item Renderers can also be reusable by creating a named component instance outside of the list-based control. This component must have an id property and contain the rendering logic of the Item Renderer. Using data bindings, the component is assigned to the itemrenderer property of one or more data properties of a list-based control.

<mx:Component id="ImageRenderer">
 <mx:VBox width="100%" height="140"
 horizontalAlign="center" verticalAlign="middle">
 <mx:Image source="{'assets/'+data.image}"/>
 <mx:Label text="{data.image}" />
 </mx:VBox>
</mx:Component>

<mx:DataGridColumn headerText="Image"
 dataField="image" width="150"
 itemRenderer="{ImageRenderer}"/>
In the previous example, note that the Item Renderer component contains 2 UI controls – Image and Label. When using multiple controls within an Item Renderer, a layout container is required. In this example, a VBox was used.
If this post answers your question or helps, please kindly mark it as such.
Thanks,

Apex 4.0 display image item :BLOB column returned by SQL statement

Hello
I'm creating an display image item in apex 4.0. The source is a BLOB column returned by SQL statement.
When I'm issuing an sql statement like this:
   select lado.blob_content
   from   large_documents      lado
   ,        large_doc_headers    ladh
   where lado.ladh_nr = ladh.nr
   more criteriait works fine.
When I create a function inside a package with the same query (in a cursor)
function get_image(some parameters in) return blob
Following in apex by:
select get_image(some parameters) from dualI get a
ORA-06502: PL/SQL: numeric or value error: character string buffer too smallAnybody any idea why this does not work?
Regards Erik

Hi Eric,
the environment assumes varchar2-output by default, which will be limited to 32767 characters and may have problems with binary formats. You could define a blob-variable to select the value into.
DECLARE
l_blob BLOB;
BEGIN
SELECT get_image(some parameters)
    INTO l_blob
    FROM dual;
END;
/If you expect the BLOB-Content to be text (you should consider CLOB then), you may use UTL_RAW.CAST_TO_VARCHAR2 to convert the content. If your object is larger than the maximum varchar2 size, or you want to convert BLOB to CLOB, you might be interested in some converter like described here: {message:id=559749}
Hope this is what you were searching for.
