DataGridColumn/Wordwrap problem
I have been attempting to get my data grid to properly word
wrap. The problem seem to be that the height of the row with the is
set for all rows by the first occurrence and not row by row. Is
this correct? Is it possible to make each row size to the contents?
I am currently using an itemRenderer as follows:
<mx:DataGridColumn headerText="Feature" dataField="@name"
wordWrap="true">
<mx:itemRenderer>
<mx:Component>
<mx:Text text="{data.@name}" selectable="false"/>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
Thanks
Set the DataGrid property variableRowHeight ="true"

DataGridColumn labelFunction Problem
I am trying to get the DataGrid to behave normally, as most
DataGrids do. Here's the setup....
For example:
ColumnA: Qty. (default value: 0)
ColumnB: Price (default value: 9.99)
ColumnC: (ColumnA * ColumnB)
In this case I'm using a labelFunction to calculate ColumnC.
When I run the program and select ColumnA (Qty.) and I change the
value from 0 to 1 and I hit the "ENTER" key, the calculation is
executed and ColumnC is updated as expected. But, if I hit the
"TAB" key instead, it moves the focus to the next editable cell on
that row, but it does not execute the calculation (labelFunction).
This to me seems like it should be a given, since most DataGrids in
most development platforms support this type of behavior (execute
on lostfocus/leavecell, etc). But, it looks like it's not built
into Flex 2.0's DataGrid.
My other thought, was to try to capture the "Leave Cell"
event....I was unable to find a "Leave Cell" event.
Any thoughts, ideas or suggestions would be greatly
appreciated!
- MikeWell, my solution works only if you're not using any other
controls (as I just found out). Basically, this solution prevents
the user from ever moving the focus out to any other control.
So far, my experience with the implementation of the Datagrid
in Flex has been filled with frustration. There are a bunch of
"common" scenarios that are proving very difficult to implement.
For example:
1) It would be nice to be able to have a calculated column
that works. (I set up a labelfunction, but this doesn't update
until I leave the row, rather than leave a cell, also it doesn't
trigger when using the tab key...see #3).
2) It would be nice to be able to add a combobox to a
datagrid column (I know Flex can do this, but not easily, or
intuitively).
3) It would be nice to be able to control the tabbing
behavior in the datagrid, it's doesn't work as one would expect it
to. (I set focus to cell in code, then when I hit the tab key, it
moves the tab out of the datagrid. When I click back into the
datagrid and hit the tab key again...it works as I would expect.
But, when I update data in a column and tab off it doesn't trigger
the itemEditEnd event...and unfortunately there is no cell edit end
event).
I could go on, but those are my Top 3 problems right now. If
anyone has suggestions, ideas or solutions I would love to hear
them.
Thanks,

WordWrap property on an item in a datagridcolumn
Hi,
I coded it this way:
<mx:DataGridColumn wordWrap="true" width="200"
headerText="Comments" dataField="comments">
The text value doesn't wrap around though. It gets clipped.
What am i missing?
Thanks in advanced.Hi Peter,
Thanks for the quick response. I poked around a little bit
more in the online help and stumbled into the 'itemrenderer'
property of the datagridcolumn component ... tried it out and
managed to get the result that I was looking for. Here's how I
coded it:
<mx:DataGridColumn width="320" headerText="Comments"
dataField="comments">
<mx:itemRenderer>
<mx:Component>
<mx:Text text="{data.comments}" selectable="false"/>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
Again, thanks for taking the time looking into it.
I'm having a great time learning Flex! The sample apps are
such great starters!

Dynamic accordion with dynamic datagrid
I’m trying to create a dynamic accordion with embedded
datagrids in each accordion area. I have the base working but have
2 problems I can’t seem to figure out.
Bases; the accordion uses a repeater and vbox with a custom
component from a webservice result set to create the accordion. The
custom component has another webservice that gets a value from the
repeater to pass it to the custom component.
My 2 problems:
1. how do I prevent the custom component from running the
webservice until the accordion item is clicked or the area is
visible? Otherwise I end up will a bunch of queries hitting the DB
and if there is several items for the accordion and many items from
the datagrid its slower.
2. how can I get the datagrid query to refresh when the
accordion item is clicked? Because the data may change I am not
able to see the updated data unless I reload the entire
application.
1 thing I did try. With the tab control you can use the
show() event and the data will refresh just fine, but with the
accordion, the show() event does not seem to fire. Its as if they
are all visible.
Any help here would be much appreciated, I’ve been
racking my brain for days now and I sure it is something simple
that I am missing. Thanks in advance.

Based on the examples
here
and
here
I have a datagrid which uses an XML object as its dataprovider. The
xml goes like this:
<questions>
<question>
<prompt>What are your heroes?</prompt>
<answers>
<answer>
<correct>true</correct>
<text>Luther Higgs</text>
</answer>
<answer>
<correct>false</correct>
<text>Barney Fife</text>
</answer>
</answers>
</question>
</questions>
Well formed (if a bit confusing) xml. In my datagrid I have
two columns. The second column binds to
questions.question.answers.answer.text and works just fine. The
datagrid's editable property is set to true, and I'm able to click
on the second colum and type and it saves the answer back into the
xml object just fine. The problem lies in my first column. The mxml
looks like this:
<mx:DataGridColumn headerText="Correct">
<mx:itemRenderer>
<mx:Component>
<mx:VBox horizontalAlign="center">
<mx:RadioButton id="myRadioButton"
buttonMode="true" useHandCursor="true"
group="{outerDocument.myRadioButtonGroup}"
selected="{data.correct}"/>
</mx:VBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
The problem is that the radio buttons' selected properties
aren't bound to the xml, that is the one that is true doesn't
display as selected. If I set the datagridcolumn's editable
property to false, clicking on the radio button doesn't affect the
xml at all either. If I leave the editable property of the
datagridcolumn as the inherited default of true (based on the
parent datagrid's editable property) when I click on the radio
button the default itemEditor appears (a text input box) which
contains the following text:
</answer>
and when I leave the editor (click outside or hit enter) the
xml then looks like this:
<answers>
<answer>
<correct>true</correct>
<text>Luther Higgs</text>
</answer>
<answer>
<correct>false</correct>
<text>Barney Fife</text>
<null><answer>
<correct>false</correct>
<text>Barney Fife</text>
</answer></null>
</answer>
</answers>
I have seen controls that don't have the xml path written
correctly display the entire xml node rather than just the
contained data, but I can think of no reason anything should Ever
reference just the closing tag. To me this looks like a bug in the
data bindings between the radio button and the xml object.
Just to clear the air to avoid suggestions that will work but
not meet the design requirements, what I need is a datagrid that
has a radio button group (only one correct answer out of the group)
in the first column and strings in the second column which need to
be editable. I suppose I could write some hairy event listener code
and manually hack things together, but aside from avoiding that
headache, I'd love to use data bindings for what they were intended
for - I just need to know why it doesn't appear to be working
right. Much thanks in advance for any and all help.Searching the LiveDocs revealed the answer. Under the topic
"Using an E4X expression in an <mx:Binding> tag" I found that
if instead of
<mx:RadioButton id="myRadioButton"
buttonMode="true" useHandCursor="true"
group="{outerDocument.myRadioButtonGroup}"
selected="{data.correct}"/>
I have
<mx:RadioButton id="myRadioButton"
buttonMode="true" useHandCursor="true"
group="{outerDocument.myRadioButtonGroup}"/>
<mx:Binding source="myRadioButton.selected"
destination="data.correct" />
It works just perfectly.
Apparently binding between XML and the selected property of a
radio button (which is of type boolean) needs the <mx:Binding
/> rather than the in-tag curly brace notation.
P.S. The link on livedocs is here:

String overlapping problem in mx:List caused by wordWrap
I'm using mx:List to display String items. The dataProvider is XMLListCollection. Some of the String is long so it takes more than one rows. I use the wordWrap to display the long String in more than one rows. The problem is that the next String item will overlapping with the long String. The mx:List can not adjust the vertical space for the Strings that needs more than one rows dynamically. Any suggections?
Here is solution: variableRowHeight="true"

Problems with DataGrid and WordWrap
Hi all,
I have some problem with the headerText property of the
mx:DataGridColumn, when the text is longer than the column width.
Even if I set headerWordWrap property to true, sometimes the text
shown in the header is truncated.
The behaviour is strange: if you change the column width
moving the mouse, sometimes the text is truncated and other times
it isn't.
Can somebody help me or confirm that it is a Flex bug, please
thanks
cheers,
ennioHad you installed Flex 2 Hotfix 1? This fix fixes many bugs
when columns are resized. -
Dynamic datagrid rowHeight and itemRenderer problem
Hi guys,
Long time listener; first time caller....
I have had a look around the forums here and i can see there are a lot of similar issues to the one i'm currently having but not so many solutions. Not sure if i'll have any better luck with my question but here goes...
My issue is to do with the row height of a datagrid row not matching up properly with the height of the custom iterm renderer used on a column.
The item renderer consists of an HBox containing an image and a textArea. The image will not always be present and the text area can contain a couple of words or many lines of text.
I have overridden the measure function of the item render in which i am manually setting the HBox's height and measuredHeight.
Problem is that i have to find some way of triggering a redraw of the datagrid AFTER if have set the item renderers height, but i dont seem to be able to directly access the in-line renderer from the parent class.
If anyone could throw any suggestions my way it would be greatly appreciated!
thanks '

Unfortunately the whole code is much too large to fit in here, but here are the main working parts.
I hope this helps.
What i am getting when running this is strange. When i run the first time and when i resize a column, the row height is incorrect, but then when i just click the 'column stretch' arrow (ie the space between the column headers) and dont actually resize at all, the row heights re-calculate and they fit perfectly.
This makes me think that i need to trigger this event manually AFTER the itemRenderer has been calculated.
EDIT: forgot to add the measureGrid function -
I have an ApplicationControlBar above a data grid. The data grid has widths specified and is bound to a data source that is populated by a service call. The mark up below causes the description column to disappear and the header row is about 10 times taller than it should be. If I put an empty label inside the application bar it all loads as expected. I tried putting an updateComplete handler on the grid but I found two problems. Adding a trace to the method handler showed that it just kept firing over and over. It also prevented resize of the grid columns.

Problem with DataGrid/AdvancedDataGrid using variableRowHeight
I need a column with more that an information for example(title and description of a movie in the same cel)
and for that I created a custorm renderer to hold the information togeter. Following the code for the renderer..
<?xml version="1.0" encoding="utf-8"?>
<mx:VBox xmlns:mx="http://www.adobe.com/2006/mxml" width="100%"
verticalScrollPolicy="off" horizontalScrollPolicy="off"
paddingBottom="0" paddingLeft="0" paddingRight="0" paddingTop="0">
<mx:HBox horizontalGap="0">
<mx:Label text="Title:"/>
<mx:Label text="{data.title}"/>
</mx:HBox>
<mx:HBox horizontalGap="0" paddingLeft="3" paddingRight="3">
<mx:Label id="descLbl" text="Description:"/>
<mx:Text text="{data.description}" width="{width-6-descLbl.width}"/>
</mx:HBox>
</mx:VBox>
Because I don't need something special when the data is get or set I didn't override that functions.
Since the Text control need explicit width to wordWrap the text I binded that value to the available space instead of use "100%".
Of course not all the descriptions has the same length and the description could take 1, 2, 3 or more rows so I set the valiableRowHeight of the grid to "true".
When load everything works, mistakes comes when you try to enlarge the column to make a description to take less row (example row #1 before sesizig the description need 3 rows of text and after the resizing the descriotion need only 2 rows) as soon as you resized the column you notice that the text of the description effectly refreshed and takes only 2 rows but the height of the row could countain the 3rd row of the description that no more exists.
If you do another resize operation the row height refresh correctly (example click on the column separator)
I also tried to do table.validateNow(); on the mouse up event of the table.
Following the code of a simple application.

Hope can you help me guys otherwise I will be creazy very soon trying to solve this problem.Does your parent clip have any styles associated with it?

@Embed embeds at compiletime, so it can't take a variable. If
you want to
embed the graphics, embed them to the main file and use
DataGrid's
iconFunction to pass an icon to the itemRenderer.

Problem with checkbox item renderer in datagrid
I have a data grid having check box as an item renderer. I have viewed many posts in this forum but nothing useful in my case. I am failed to bind my datagrid itemrenderer checkbox with the field of dataprovider i.e. listUnitMovement.CHECK_PATH. Then I have to traverse data provider to check which checkboxes are checked.
[Bindable]
var listUnitMovement:XMLList=null;
In a function call
public function init(event:ResultEvent):void
listUnitMovement=event.result.unitmovement;
<mx:DataGrid id="dg_country"
dataProvider="{listUnitMovement}"
enabled="true">
<mx:columns>
<mx:DataGridColumn>
<mx:itemRenderer>
<mx:Component>
<mx:CheckBox selectedField="CHECK_PATH" />
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
<mx:DataGridColumn headerText="Latitude" dataField="NEW_LAT" visible="false"/>
<mx:DataGridColumn headerText="Longitude" dataField="NEW_LONG" visible="false"/>
<mx:DataGridColumn>
<mx:itemRenderer>
<mx:Component>
<mx:Button label="Details"/>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>Hi,
Do you want to just check/uncheck the checkboxes based on the CHECK_PATH field.
Do you want something like this...
<?xml version="1.0" encoding="utf-8"?><mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.collections.ArrayCollection;[
Bindable]
private var listUnitMovement:ArrayCollection = new ArrayCollection([{CHECK_PATH:true,NEW_LAT:109.233,NEW_LONG:232.22},{CHECK_PATH:true,NEW_LAT:109.233,NEW_LONG:232.22},{CHECK_PATH:false,NEW_LAT:133.233,NEW_LONG:702.22}]);]]>
</mx:Script>
<mx:DataGrid dataProvider="{listUnitMovement}">
<mx:columns>
<mx:DataGridColumn>
<mx:itemRenderer>
<mx:Component>
<mx:CheckBox selectedField="CHECK_PATH" change="data.CHECK_PATH=selected" />
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
<mx:DataGridColumn dataField="NEW_LAT"/>
<mx:DataGridColumn dataField="NEW_LONG"/>
</mx:columns>
</mx:DataGrid>
</mx:Application>
Please let me know clearly what's your problem...Do you want to just bind the check box based on XmlList or something else..?
Thanks,

Problem overloading "set data" function on Button DataGrid Renderer
Hi all, I'm hoping this is something simple.
I have a class that extends mx.controls.Button and implements mx.core.IDataRenderer. I need to set the button icon whenever the Data property is set from the DataGrid. My problem is that my overloaded set/get Data function are never called (I've stepped through the code in debug). Instead the set/get functions in Container.as (Flex 3.4 SDK) get called.
Here's the basics code:
exportButtonRenderer.as
package controls
import flash.events.Event;
import flash.events.MouseEvent;
import mx.controls.Button;
import mx.core.IDataRenderer;
import mx.controls.dataGridClasses.DataGridListData;
import mx.controls.listClasses.BaseListData;
import mx.events.FlexEvent;
import mx.controls.Alert;
import model.descriptors.compDescriptor;
import events.exportClickedEvent;
public class exportButtonRenderer extends Button implements IDataRenderer
// embed your icons
[Embed(source='/assets/icons/export.png')]
[Bindable]
public static var imageExport:Class;
[Embed(source='/assets/icons/blank.png')]
[Bindable]
public static var imageBlank:Class;
public function exportButtonRenderer()
super();
private var _listData:DataGridListData;
override public function get listData():BaseListData
return _listData;
override public function set listData(value:BaseListData):void
_listData = DataGridListData(value);
private var _data:Object;
override public function get data():Object
return _data;
override public function set data(value:Object):void
_data = value;
override protected function clickHandler(event:MouseEvent):void
super.clickHandler(event);
Now I know I'm using the Flexlib TreeGrid and not a standard DataGrid but when I trace through all the code all code firing the set/get functions is coming from the DataGrid anyway.
Here's the my Grid def in my main app mxml:
Header 1
<flexlib:TreeGrid
id="MKTXGrid"
dragEnabled="false" sortableColumns="false" showRoot="false"
disclosureClosedIcon="@Embed(source='/assets/icons/arrow_right.png')"
disclosureOpenIcon="@Embed(source='/assets/icons/arrow_down.png')"
folderOpenIcon="@Embed(source='/assets/icons/psd.png')"
folderClosedIcon="@Embed(source='/assets/icons/psd.png')"
click="MKTXGrid_clickHandler(event)"
doubleClickEnabled="true" doubleClick="MKTXGrid_doubleClickHandler(event)" left="0" right="0" top="0" bottom="16">
<flexlib:columns>
<flexlib:TreeGridColumn dataField="Name" headerText = "Name" minWidth="200" width="200" editable="true"/>
<mx:DataGridColumn dataField="ExportName" headerText = "Export Name"/>
<mx:DataGridColumn dataField="Export" headerText = "Export" width="50" minWidth="20" resizable="false">
<mx:itemRenderer>
<mx:Component>
<mx:Box horizontalAlign="center" width="100%" verticalScrollPolicy="off" horizontalScrollPolicy="off">
<controls:exportButtonRenderer label="Export" icon="@Embed(source='assets/icons/export.png')" width="12" height="12" useHandCursor="true">
<controls:click>
<![CDATA[
import events.exportClickedEvent;
var e:exportClickedEvent = new exportClickedEvent();
e.itemData = data;
dispatchEvent(e);
]]>
</controls:click>
</controls:exportButtonRenderer>
</mx:Box>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</flexlib:columns>
</flexlib:TreeGrid>
Nothing too special going on.
I know this can be done, I've seen examples in the SDK:
http://opensource.adobe.com/svn/opensource/durango/trunk/ExternalFlexTools/com/dougmccune/ containers/accordionClasses/AccordionHeader.as
By the way I've stepped through the code of the TreeGridItemRenderer class in Flexlib which works correctly and the class def starts like this:
TreeGridItemRenderer.as
import flash.display.DisplayObject;
import flash.display.InteractiveObject;
import flash.display.Shape;
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.geom.Point;
import flash.geom.Rectangle;
import flexlib.controls.TreeGrid;
import mx.controls.Image;
import mx.controls.dataGridClasses.DataGridListData;
import mx.controls.listClasses.BaseListData;
import mx.controls.listClasses.IDropInListItemRenderer;
import mx.controls.listClasses.IListItemRenderer;
import mx.core.IDataRenderer;
import mx.core.IFlexDisplayObject;
import mx.core.IToolTip;
import mx.core.SpriteAsset;
import mx.core.UIComponent;
import mx.core.UITextField;
import mx.events.FlexEvent;
import mx.events.ToolTipEvent;
import mx.events.TreeEvent;
import mx.managers.ILayoutManagerClient;
import mx.styles.IStyleClient;
public class TreeGridItemRenderer extends UIComponent
implements IDataRenderer,
IDropInListItemRenderer,
ILayoutManagerClient,
IListItemRenderer
Any help would be great!That's because you put your component in a Box. The DataGrid is setting the Box's .data property and no code is setting the one on your component. You shouldn't really need Box. You can override updateDisplayList to center your Button instead.
