HI!!
I have taken a look at many of the itemRenderer examples, but I have not seen
what I am trying to do.
I am building a grading screen. the screen is a DataGrid with an unknown number
of rows and columns so I am building it dynamically.
for this test its just 1 row of 2 columns
=======================================================================
for(var i:Number = 0; i < numOfStudents; i++)
{
//add data to the ArrayCollection
columnCollection.addItem({Name:xmlCurrGrades..student[i].name,Assesment:"" }
}
// make the ArrayCollection the Dataprovider
gradeGrid.dataProvider = columnCollection;
gradeGrid.x = 350;
gradeGrid.y = 100;
for (var i:Number = 1; i<gradeGrid.columns.length; i++)
{
// grab the column instances
var gradeGridCol:DataGridColumn = gradeGrid.columns[i];
// assign the new item renderer
var renderer:ClassFactory = new ClassFactory(twoBtnPlusTextArea);
// assign our custom renderer
gradeGridCol.itemRenderer = renderer;
}
// add the dataGrid to the screen
addChild(gradeGrid);
========================================================================
Each DataGrid Cell contain 2 buttons and a Text field. the data from the XML
looks like this for each cell
[EMAIL PROTECTED]);
[EMAIL PROTECTED]);
[EMAIL PROTECTED]);
What I don't understand is how to get this data into the data property. The
"dataField" is only a single String.
My override of set data() in the itemRenderer looks like this
=========================================================================
override public function set data(value:Object):void
{
if(value != null)
{
super.data = value;
if(value.docStatus == 0)
{
docBtn.setStyle("color","yellow");
}
else
{
docBtn.setStyle("color","orange");
}
if(value.feedBKStatus == 0)
{
feedBkBtn.setStyle("color","green");
}
else
{
feedBkBtn.setStyle("color","blue");
}
txarea.text = value.gradeData;
}
}
======================================================
Thanks

Every example out there should be doing this. Look at
the source for mx.controls. listClasses. TileListItemRend erer. You can also
find examples on my blog (blogs.adobe. com/aharui)

renderers are data driven. The .data property should
hold the items from the XML file and you should set the buttons and textArea
based on what you find in the .data property.

question
HI!!
I have a question about using a DataGrid with a custom
itemRender.
Each of my DataGrid Cells contains an HBox within which are
2 buttons
and a text field. I realize that there are performance issues
with
this design but these are my current specs.
The problem I am
having is how to initialize the two buttons and the
text area at startup.
Each button can be in one of four states and the
text area can contain any
number between 1 and 100, the info comes out
of a XML file which I read in at
startup.
I have been unsuccessful in trying to walk through the DataGrid
using
getChildAt to gain access to the Cell and Buttons.
I'm looking
for any ideas.
