Re: [flexcomponents] Struggling with itemRenderer in DataGrid

2007-03-02 Thread Steve Gustafson 

Ok.  This is alot closer to where I am trying to get!

When I try: _col3.itemRenderer.properties = {dataProvider:myCBData};

FlexBuilder throws the following error:
Access of possibly undefined property properties through a reference with
static type mx.core:IFactory

So now it looks like I'll either have to figure out how to access the
iFactory, or learn to write my own IFactory as suggested.

It seems like this should be simpler!

This should set you up to use the myLevels in every ComboBox.



The comboBox has built-in logic to set the selectedItem based on what it
sees in the data property.  In your case you might want to override the data
setter and choose selectedIndex then.



FWIW, using VBox to wrap will be slower than ComboBox straight up.

RE: [flexcomponents] Struggling with itemRenderer in DataGrid

2007-03-02 Thread Alex Harui 
You'll have to override the data setter.
 
override public function set data(value:Object):void
{
}
 
The value object contains the data for an entire row in the DataGrid.
If you can then calculate the selectedIndex based on the data in the
row, you are set to go.

RE: [flexcomponents] Struggling with itemRenderer in DataGrid

2007-03-01 Thread Alex Harui 
Your itemRenderer is not a ComboBox, it is a VBox containing a ComboBox.
The DataGrid sets the .data property on the VBox and you haven't written
the code to pass it on down to the ComboBox.

 

You can either write that code, or use ComboBox as the top-level tag so
you are really using a subclass of ComboBox as the renderer, which is
the recommended practice.

Re: [flexcomponents] Struggling with itemRenderer in DataGrid

2007-03-01 Thread jwopitz 

First off, reinstate the VBox.  The override the setter data
(value:Object).  There you can either set the cb's dataProvider like cb.dp =
data.someObject

or if you are doing it in MXML, you can bind the dataprovider of the CB to
some expected property of the data property of the VBox.

Doing it via script is a bit tricky, because if your data value doesn't
contain the targeted property it will throw a runtime error.

You can write you own IFactory, or you can do this:

 

_col3.itemRenderer = new ClassFactory(comboR);
_col3.itemRenderer.properties = { dataProvider :
arrayToUseAsDataProvider};



Then your ComboBox dataproviders will be given assigned that array.

This should set you up to use the myLevels in every ComboBox.

 

The comboBox has built-in logic to set the selectedItem based on what it
sees in the data property.  In your case you might want to override the
data setter and choose selectedIndex then.

 

FWIW, using VBox to wrap will be slower than ComboBox straight up.

First off, reinstate the VBox.  The override the setter data
(value:Object).  There you can either set the cb's dataProvider like
cb.dp = data.someObject

or if you are doing it in MXML, you can bind the dataprovider of the CB
to some expected property of the data property of the VBox.  

Doing it via script is a bit tricky, because if your data value doesn't
contain the targeted property it will throw a runtime error.

Re: [flexcomponents] Struggling with itemRenderer in DataGrid

2007-03-01 Thread Steve Gustafson 

Perhaps I am not being clear.  I know I can set the dataProvider within the
component.  What I need to know is how I can either change the dataProvider
when the itemRenderer is called.

I want to use this itemRenderer in multiple grids.  Each grid is to use the
itemRenderer with either a different dataProvider, or update the
dataProvider with different data.

So I'm trying to something like:

public function createPositionTable():void
{
   _col1 = new DataGridColumn;
   _col2 = new DataGridColumn;
   _col3 = new DataGridColumn;

   _col1.headerText= Position;
   _col1.dataField = Description;
   _col1.editable = true;
   _col1.width = 100;

   _col2.dataField = Type;
   _col2.headerText= Type;
   _col2.editable = true;
   _col2.width = 50;

   _col3.dataField = levelCode;
   _col3.headerText = Level Code;
   _col3.width = 150;
   _col3.editable = false;
// HERE I SET THE itemRenderer - but want to use a different dataProvider
// OR AT LEAST UPDATE THE ORIGINAL DATAPROVIDER WITH NEW DATA
   _col3.itemRenderer = new ClassFactory(comboR);
   _col3.editorDataField = levelCode;

   _columns = new Array(_col1,_col2,_col3);
   _datagrid = positionsGrid;
   _datagrid.columns = _columns
   _datagrid.sortableColumns = false;
   _datagrid.dataProvider = objAdminTableGridDP;
   _datagrid.dragEnabled = false;
   _datagrid.dragMoveEnabled = false;
   _datagrid.dropEnabled = false;
   _datagrid.editable = true;
   _datagrid.rowHeight = 30;
   updateTablesButton.label = 'Update Positions Table';
}

public function createDepartmentTable():void
{
   _col1 = new DataGridColumn;
   _col2 = new DataGridColumn;
   _col3 = new DataGridColumn;

   _col1.headerText= Position;
   _col1.dataField = Description;
   _col1.editable = true;
   _col1.width = 100;

   _col2.dataField = Type;
   _col2.headerText= Type;
   _col2.editable = true;
   _col2.width = 50;

   _col3.dataField = levelCode;
   _col3.headerText = Level Code;
   _col3.width = 150;
   _col3.editable = false;
// HERE I SET THE itemRenderer - but want to use different dataProvider
// OR AT LEAST UPDATE THE ORIGINAL DATAPROVIDER WITH NEW DATA
   _col3.itemRenderer = new ClassFactory(comboR);
   _col3.editorDataField = levelCode;

   _columns = new Array(_col1,_col2,_col3);
   _columns = new Array(_col1,_col2,_col3);

   _datagrid = positionsGrid;
   _datagrid.columns = _columns
   _datagrid.sortableColumns = false;
   _datagrid.dataProvider = objAdminTableGridDP;
   _datagrid.dragEnabled = false;
   _datagrid.dragMoveEnabled = false;
   _datagrid.dropEnabled = false;
   _datagrid.editable = true;
   _datagrid.rowHeight = 30;
   updateTablesButton.label = 'Update Positions Table';
}

Your itemRenderer is not a ComboBox, it is a VBox containing a ComboBox.
 The DataGrid sets the .data property on the VBox and you haven't written
the code to pass it on down to the ComboBox.



You can either write that code, or use ComboBox as the top-level tag so
you are really using a subclass of ComboBox as the renderer, which is the
recommended practice.

Help.

I posted this on FlexCoders with no response, so I thought I would try
here too.



I'm trying to use an itemRenderer to create a comboBox in a DataGrid that
is being created with AS.

I can create the comboBox, but I am struggling with being able
