Custom pegging component for data grid in flex

A pegging component useful when you want to display a limited amount of data in datagrid.
<code>
<pagging:Pagging id="pagging" size="15" ui="{dataGridRef}" dp="{data}" />
</code>

Flex Builder 2 uses Actionscript 3.
You will need to write a renderer for for this column.
There are a lot of examples of datagrids with images in them.

Dump in Value-Help Component for date

I created a Value-Help-Component for date fields. (I cannot use the standard value help, because I need the help to start in the month, the user is working on).
I am using the Date Navigator to select a date.
If I first change the month with an arrow of the date navigator and then select a date I get a dump in the method IF_WD_CONTEXT_ELEMENT~GET_ATTRIBUTE_REF in line
attr_info = me->node_info->if_wd_context_node_info~get_attribute( name_only ).
, because the element does not have a node_info.
If I just choose a date in the preselected month (without using the arrows of the date navigator) everything is fine.
Does anybody have an idea??
Many thanks in advance.

I found the "solution" to the problem myself.
I used the method bind_structure in the component containing the date navigator.
After I replaced it by set_static_attributes it worked without producing dumps.
Very strange!

"advanced data grid" with flex builder 3.0

I'm getting watermark as "Flex Data Visualization
Trial" when tried to use advances data grid with flex builder 3.0. There are some links floating on the internet where it's suggested that the license key should be provided in the flex-config.xml to avoid this issue. I would like to know if this componenet is stable with flex builder 3.0 and is it ok to use this in production environment?

Someone from Adobe might be able to answer more definitely
but it's probably just not considered compatible with a modified
Eclipse (at least, the installer). It may just be the installer
blowing up when it shouldn't. I think Adobe doesn't want to support
install configurations that they don't have setup and tested. I had
a similar issue once and solved it by doing the following... not
sure if it'll work, and it's more of a last resort:
Setup a regular eclipse install - install the plugin there.
Somehow, you'll have to keep track of all the files it adds, either
using timestamps or some compare software. It should be a bunch of
files and/or folders in the '/plugins' directory, and possibly a
few others in '/configuration', maybe '/features'. Take all the new
folders and any jar files etc, and drop them into the same folders
in your special Eclipse version. Hopefully when you start it up
you'll get the Flex functions...
Of course, you could end up hosing your entire "NWDS"
(whatever this is) install. So you probably want to test it out
first!

How to put an image in a data grid in Flex Builder 2

Hi All,
I need to populate a data grid with some text data received
from a web service and, in a particular column of the datagrid, I
have to put an image depending of a specific data returned me by
the web service.
It seems that there is the possibility to add an image in
data grid column with the cellRenderer properties, but this
property is available only for ActionScript 3.
I'm developing an application in Flex Builder 2 that run
ActionScript 2 and cellRenderer properties is not available. Is it
right?
If no, I will can use this cellRenderer properties in my
application. Please, can you show me an example?
If yes, there is a way to insert an image in datagridcolumn
with ActionScript 2?
Thank you very much
Regards

Populating a Forum froma data grid in Flex

I have a forum that I would like to pouplate to be able to edit the information in Flex (flash builder four). So how would I click on a row of data (from a datagrid) and have it populate the forum?

Hi,
Do you mean a Form? Try listening for the "gridClick" event on the DataGrid and looking at the "item" property of the event. This event dispatches when the user clicks on the DataGrid and item will be the data object from the row that the user clicks on. I've written up a simple example below:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
 xmlns:s="library://ns.adobe.com/flex/spark"
 xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
 <s:layout>
 <s:VerticalLayout gap="10" paddingTop="10" paddingRight="10" />
 </s:layout>
 <fx:Script>
 <![CDATA[
 import spark.events.GridEvent;
 protected function dataGrid_gridClickHandler(event:GridEvent):void
 var item:Object = event.item;
 if (item)
 keyTI.text = item.key;
 nameTI.text = item.name;
 ]]>
 </fx:Script>
 <s:DataGrid id="dataGrid" gridClick="dataGrid_gridClickHandler(event)">
 <s:ArrayCollection>
 <fx:Object key="1000" name="Abrasive" />
 <fx:Object key="1001" name="Brush"/>
 <fx:Object key="1002" name="Clamp"/>
 <fx:Object key="1003" name="Drill"/>
 <fx:Object key="1004" name="Epoxy"/>
 <fx:Object key="1005" name="File" />
 <fx:Object key="1006" name="Gouge"/>
 <fx:Object key="1007" name="Hook"/>
 <fx:Object key="1008" name="Ink" />
 <fx:Object key="1009" name="Jack" />
 </s:ArrayCollection>
 </s:DataGrid>
 <s:Form>
 <s:FormItem label="key">
 <s:TextInput id="keyTI" />
 </s:FormItem>
 <s:FormItem label="name">
 <s:TextInput id="nameTI" />
 </s:FormItem>
 </s:Form>
</s:Application>
Of course, you'll have to write some code so that the you can edit the data and save it from the Form. Hope this helps.

after Deploying and in Gac, when configuring Receive Pipeline, it shows no properties in Decode stage ?
MBH

There is nothing wrong with your code it removes the lastline, if there is no carriage return on it.
If your input file is like:
line1 <cr><lf>
line2 <cr><lf>
line3
The result is:
line1 <cr><lf>
line2 <cr><lf>
But if your input file is like:
line1 <cr><lf>
 line2 <cr><lf>
line3 <cr><if>
The result is:
line1<cr><lf>
line2<cr><lf>
<empty line>
So when you have a carriage return on the last line, it results in an empty line, can this be the cause of your problem?

Display image into Data Grid

Hello,
I have to display into a data grid, in Flex 2, 2 columns:
first column ( "Images") must contain a picture with an object and
second column (" quantity") must contain the amount of that object
that I want to buy. The problem is that I must take the name of the
image from an .xml file, specified like this:
<mx:DataGrid id="obj" dataProvider="{ObjList}" > where
ObjList is the .xml file with <name/>
<picture_address/> etc.
The second column must contain a textbox so I can input a
number of items for each picture ( can be also a combobox where
from I can select some value, from 1 to 20 for example).
I've searched the Internet and I haven't found a solution
yet. Please give me a link or a solution for this problem.
Tudor

use itemrenderes.... the example below shows how to add an
image.... you can do the same thing with a text box or combo box
<mx:DataGridColumn width="10" headerText="Image">
<mx:itemRenderer>
<mx:Component>
<mx:Canvas width="100%" height="100%">
<mx:Image verticalCenter="0" horizontalCenter="0"
source="{data.picture_adress}""/>
</mx:Canvas>
</mx:Component>

please help me out
Thanks

Hi,
columns is an array. After the dataprovider is set, save the columns to a temporary array
private var tempColumns:Array;
tempColumns = datagrid.columns;
When the reset button is clicked, reset the columns from the tempArray.
datagrid.columns = tempColumns;

Ok I was getting ready to post the renderer code and then found the problem. I had copied this code from another renderer which had contentBackgroundAlpha=0 in the MXAdvancedDataGridItemRenderer tag. When I removed it, the style of the TextArea worked as intended. Your comment helped me to take a closer look at the renderer code, so thank you.

Flex datagrid custom itemEditor - not returning data

Hi,
I am new to flex and this is a basic "How to" question.
I want to write custom item editors and renderers for a datagrid column.
I am facing two problems here
1) override public function get data() : Object is not working. however, if the type of the column is just text then override public function get text():String is working. Specifying editorDataField in the datagrid column definition is working for some types ex:Strings, Numbers
2) Nothing is working for slightly more complex types like an Image. even editorDataField is not working. Somewhere between the user editing the data (in the case of an image, edit = browse, select & load an image) and grid asking for data at itemEditEnd, the entire data loaded by the user is disappearing and it is returning null or some default value I'd set it to in override public function set data().
I am aware that datagrid reuses both editors and renderers but I dono how the data user has set is getting lost while the focus is on the same cell
I have tried to use getter setter for this custom data field mentioned in editorDataField but when I do so, nothing works.. it fails even for string type
It should be a simple thing to do and I am sure I am making some silly mistake .. please help me out. It has driven me nuts since today morning..
any pointers would be really appreciated.

Hi,
thanks for the info. This is the understanding that I had after reading livedocs about item renderers.
I have given the correct editorDataField and dataField. But it isnt working..I am not sure what you mean by For complex renderers, make sure the property is properly implemented on the outer component.
The weird part is specifying editorDataField works for String and not for an image. I am pasting some of code (highlighting relevant parts) below.. please have a look and tell me what I am missing.
Datagrid :
<mx:DataGrid id="dg" editable="true" rowHeight="100" width="861" x="10" y="10" height="498"
 dataProvider="{this.slideArray}">
 <mx:columns>
 <mx:DataGridColumn headerText="Text" width="100"
 resizable="true" sortable="false"
 itemRenderer = "mx.controls.Label"
 itemEditor="editors.TextEditor"
 dataField="text" editorDataField="myData"/>
 <mx:DataGridColumn headerText="Image" width="600" resizable="true" sortable="false"
 itemRenderer="mx.controls.Image"
