hi..
I get data from datagride database via xml. I've got datagrid checkboxes. When I choose any checkbox and when a new data comes, the checkboxes of some lines are shown as chosen as well.
how can I solve this problem?
Hi,
It looks like, you have to bind the data with item renderer. I have modified your code which may help you to understand.

Datagrid itemRenderer - Help needed
I am having trouble getting this little bit of code working. I am trying to build an adhoc SQL generator, where the user selects the list of fields and then is able to set the WHERE criteria in a dataGrid, each row has field, criteria (ComboBox -equals, less than, etc), Low (editable), High (editable-Text or ComboBox lookup), AND/OR static ComboBox. Some of the field selections could be regular text based fields like Name and other fields selected could be lookup fields like State. I would like to be able to on rows that are TextInput render out a TextInput for LowValue and HighValue columns and for lookup fields render out a ComboBox with the dataProvider being set by a call to addComboData.
addComboData simply uses the myDataGrid.selectedItem.fieldname to determine which of the lookup table to use and assigns that collection to CBoxdataProvider. Seems simple enough but I have not been able to figure it out, some modifications seem to work, but only for a single dg cell others give me a list but does not populate lowValue but kill all other renderers. All help is appreciated.
<mx:DataGridColumn headerText="Low" rendererIsEditor="true" editorDataField="selectedItem" dataField="lowValue" textAlign="center">
<mx:itemRenderer>

<mx:HBox horizontalScrollPolicy="off" verticalScrollPolicy="off" horizontalAlign="center">

<mx:TextInput id="lowLabel" visible="{!data.showCombo}" />
</mx:HBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>Setting the selected item is not the same as a click. If you created the renderer correctly the style should change when you actually click on the item. (Does it?)
Or are you just trying to get the first row's background to be a different style when the datagrid first shows? (Initialization problem or not working at all?) -
Datagrid itemRenderer/itemEditor trouble
I have a datagrid in a Flex project, the data grid has an XML file as the source (contents below), now due to the way it is formatted (I cannot change this) some of the data I want to display is inside a tag that isnt at the initial array level. Here is the file:
<?xml version="1.0" encoding="utf-8" ?>
<Categories>
<Category>
<CategoryName>Cat 1</CategoryName>
<CategoryLink>http://www.google.com</CategoryLink>
<CategoryData>
<CategoryDescription>This is the description of category 1</CategoryDescription>
<CategoryHeader>My Category Title 1</CategoryHeader>
<CategoryNumber>1</CategoryNumber>
</CategoryData>
</Category>
</Categories>
I need to display CategoryName, CategoryLink, CategoryData.CategoryDescription, CategoryData.CategoryNumber.
Now I blindly dropped the datagrid into the project and bound it to the data source, I get the following returned for CategoryData:
[object CategoryData_type]
Not much use, but with what appears to be a hack I changed the code for the column to read dataField="CategoryData.CategoryDescription", and hooray it works. I didnt realise at the time that this was wrong, and when I dropped in an itemEditor things went wrong. When the datagrids load they display the correct data, but then when you try to edit any of the child property fields you get the following error:
ReferenceError: Error #1069: Property CategoryData.CategoryDescription not found on valueObjects.Category_type and there is no default value.
I have looked up the error and I realise that it means that there is no value for CategoryData.CategoryDescription, but if I can display it why can i not edit it! What do I have to do to make this work?
Anyway, here is the code, it shows the default bound datagrid, a second datagrid with the hack applied, and a third hacked datagrid with an itemRenderer and itemEditor on the number columns
Can you please take a look and tell me what I did wrong, well more to the point, if there is a doc that explains how to deal with XML like this then please point me at it.
I did try changing the return type for ANY of the columns, but this fails, I also tried a labelFunction, but again I can get the [object CategoryData_type] to display, but I get the null reference exception as the datagrid loads if I try to get to the child props.

All and any advice welcome.
ShaineOne last try, I now know for sure that the data in the file is loading, I created a labelFunction on the CategoryDescription column that looks like this:
protected function dispData(item:Object, column:GridColumn):String
var t:Object = item.CategoryData;
var s:String = item.CategoryData.CategoryDescription;
return s;
Because it returns s, which I now know is undefined (which is the problem!) I managed to get a debug output. As you can see the value of t is the categorydata, and it appears to have the 3 values I need to get access to, but I have no idea how to do this. I also changed the function to read:
protected function dispData(item:Object, column:GridColumn):String
var t:Object = item.CategoryData;
var s:String = t.CategoryDescription;
return s;
But this undefines t and s! Very confused

Datagrid itemRenderer custom component formatting
OK, so this is my first attempt at an itenRenderer. This works below, but I have to imagine there is an easier way. There is also a problem with below, where the changed field (datafield=side) after the itemRenderer is applied, the text is all out of format, and there is a kind of selection on row one of that column. Obvisouly, though the translation is happening, I'm either overidding the wrong thing, or I'm doing something totally wrong.
Goal..... Show in the datagrid, the three colums below from date provided from elsewhere. (This all works), but in the 'side' data it comes in, in raw form as either an 'a' or 'b' or 'both', and I'm trying to display that as something more user friendly. So when both is read it changes it to 'No'.
Any help. This seems really easy, though I can't understanading hy my custom function screws with the cell selection, and formating?

Move focus from one to another itemRenderer inside DataGrid itemRenderer
I have a mx: DataGrid with 4 columns that have a itemRenderer with the following settings:
- Mx:DataGrid:
<code>
<mx:DataGrid id="itensPedidoCompraList"
width="100%"
height="120"
dataProvider="{ model.pedidoCompra.itens }"
editable="true"
itemEditEnd="itensPedidoCompraList_itemEditEndHandler(event)">
</code>
- Mx:DataGridColumn:
<code>
<mx:DataGridColumn headerText="{resourceManager.getString('cadastroPedidoCompra', 'ident.PercentualDesconto') }"
width="60"
textAlign="right"
rendererIsEditor="true"
editorDataField="data">
<mx:itemRenderer>
<fx:Component>
<mx:Canvas>
<input:NumberInput width="55" number="@{ data.percentualDesconto }"/>
</mx:Canvas>
</fx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</code>
The user clicks on the line of the grid and click on the column to edit.
After him change or add value, ENTER key and have to move the focus to another column in the same line.
The way I'm doing, is moving to the column below.
What is the best way to do to move to the right column?
thank youTry adding a capture phase event listener to DataGrid for keyDown and changing the key from ENTER to TAB

Ellipsis (...) in dataGrid itemRenderer
If you want a line of text in a datagrid cell to end with an ellipsis (...) when it's too long for its cell, you can set the column's item renderer to be "mx.control.Label" and that works. The entry looks like this:
Here is my line of dat...
But here's my problem.
I have created my own item renderer which is an HBox containing an image and a label. But the label doesn't truncate with the ellipsis ... when the data is too long, it simply chops the end off the displayed text.
So my question is this. How can I get the ellipsis ... to appear for the label in my item renderer? I'm using a datagrid with scaleable column widths so I can't set a fixed width on the label which would work, I know.
Cheers,
NeilThanks for your suggestion.
It didn't work but inspired me to play around with minWidth and maxWidth.
What I eventually got to work was:
maxWidth="
{this.width-28}"
...on the Label in the HBox. I'm assuming that "this" here refers to the ItemRenderer.
I had to put in the "-28" bit or it wouldn't do it. If you want more padding on the right of the ellipsis (so it doesn't hit the edge of the cell) increase the 28 to something higher. Use a lower value for less padding.
Hope this helps someone else like it did me.
Cheers,
Neil -
Problem with Datagrid itemrenderer with a Datagrid
Hi all,
I have this kind of a structure. I try to use a datagrid item renderer in a data grid column. However when I try to move rows inside the same datagrid I experience a problem. When my datagrid loads first it seems correct, but when I drag and drop a row in the same datagrid inner datagrids start to be drew in wrong rows. I checked the DB but there are no mistakes in DB records. Problem is with rendering. I suppose inner datagrids trying to draw to early or datagrid component is trying to reuse the itemrenderer. I could not find any solutions for that. Any help will be greatly appreciated..

I have created a datagrid which has suppose 4 columns out of which 1 has an option of setting as favorite just like we have in our every mail servers (gmail, yahoo, outlook, etc). I have used a linkbutton as an item renderer and its toggle property as true. so wenever i click on it its getting selected and i have used skin for selected and normal state which is a star.
The problem is that when data length exceeds and scrollbar comes in datagrid and whenever i scroll down and up the stars which are not selected are getting selected or in some scenarios the whole column stars get selected.
How to get rid of this problem ?Can I see the itemrenderer code. I'm assuming that you aren't clearing the values from previous objects in you

DataGrid itemrenderer with switch statement
Hi,
I have datagrid control with this columns
<mx:DataGrid id="dgvParagraphs" >
<mx:columns>
<mx:DataGridColumn dataField="type" headerText="Type"/>
<mx:DataGridColumn dataField="title" headerText="Title"/>
<mx:DataGridColumn dataField="content" visible="false"/>
</mx:columns>
</mx:DataGrid>
Under type column I have values from 1 to 6. Each number presents type of content. I have icons for each type. I would like to show icon instead of just number. I know this can be done using itemrenderes but I don't know how to accomplish this.If this post answers your question or helps, please mark it as such.

You might see issues with this code during scrolling, as DataGrid recycles itemRenderers, but in that case the icon information must be in the data.

Datagrid itemRenderer dynamic values
While working on an application I came across the following
problem. I've got a view with a datagrid, where I have several
columns. Each column needs 2 values displayed beneath each other in
one cell. You make an itemRenderer with 2 labels inside a VBox.
Easy so far. However since this scenario repeats several times it
seems counterproductive to make an itemRenderer for each cell. How
can I make the text property for the labels change for each cell
instead of being static in their values.
Thx in advance.Your description of your requirements and your sample code do
not paint a clear enough picture.
Your dataProvider has 4 pieces of data: batchId,
bookingNumber, valueDate, immsBranch. Your current itemRenderer
references two of those pieces of data, and you say you want to
reference the other two. You can do that easily like this:
<mx:Label text="data.valueDate"/>
<mx:Label text="data.immsBranch"/>
A basic question: will your DataGrid have two rows for each
set of 4 pieces of data? If so then I understand your problem. If
not, then you must clarify exactly how and when you would like the
4 pieces of data shown in your DataGrid.
In any case, you probably need a Repeater, and then need to
figure out how to get at the right data at the right time in the
Repeater.
See this FB 3 help topic and its sub-topics:
Dynamically Repeating Controls and Containers
Also search for this in the FB3 help to see the API:
mx.core.Repeater
You can define a listener for the Repeater for the Repeat
event to specify processing for each iteration of the
repeater. -
DataGrid - ItemRenderer - WordWrap
I have added an itemrenderer to a datagrid to change the
color of individual rows based on the value of of a cell. However,
the problem I am having is this. The word-wrap no longer works for
the datagrid. I imagine this is because I use a lable in my
itemrenderer. I have not been able to find just a good solution
that makes the cells look just like the normal datagrid, but with
different colors.
Any suggestions would be greatly appreciated.
Enclosed is the itemrenderer

Datagrid itemRenderer checkbox
Hi,
I have datagrid control in my application and I use itemRenderer to render some data received from webservice. Works just fine but I would like to disable changing state of checkbox. I am using checkbox renderer just to show data more user friendly and not that users can check and uncheck it. So how can I disable checking and unchecking (by user click interaction) my checkbox in datagrid?
I my example column with dataField "IsAlive" is the one rendered by CheckBox component.
<mx:DataGrid id="lstAllPushes" left="10" right="10" top="10" bottom="60">
<mx:columns>
<mx:DataGridColumn headerText="ID" dataField="ID"/>
<mx:DataGridColumn headerText="Start date" dataField="DateInserted"/>
<mx:DataGridColumn headerText="Expiration date" dataField="DateExpiration"/>
<mx:DataGridColumn headerText="Alive" dataField="IsAlive" itemRenderer="mx.controls.CheckBox"/>
</mx:columns>
</mx:DataGrid>
Thx in advance.Try this:
<mx:DataGridColumn headerText="Alive" dataField="IsAlive" >
<mx:itemRenderer>
<mx:Component>
<mx:CheckBox enabled="false"/>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn> -
Datagrid itemrenderer list rowcount not changing with data
I have a datagrid with an itemrenderer. the itemrenderer is a list component. I populate the list with different values for each datagrid row. this works fine. However, I want the list to reset the rowcount for each datagrid row. This is not happening. if the first datagrid row list box is 3 rows every list box in that column is 3 rows no matter what i do. here's my code:
<mx:List xmlns:mx="http://www.adobe.com/2006/mxml" rowCount="1">

if(value != null && value.MEET is ArrayCollection)
var len:Number = value.MEET.length;
arr = new Array();
for each (var obj:ObjectProxy in value.MEET){
arr.push(obj.DAYS);
this.dataProvider = arr;
//labelField = "DAYS";
this.rowCount = len;
else if (value != null && value.MEET is ObjectProxy )
this.rowCount = 1;
this.dataProvider = value.MEET;
this.labelField = "DAYS";

this.rowCount = 1;

</mx:List>Hello !
This trick makes my application freeze...
I've just an advancedDatagrid populated with arrays, and a list as renderer on some of its columns... I've got exactly the same problem (rowCount that is always the same, for all of my renderers instances), but your solution doesn't work it out...
Any idea ?
thanks a lot
