RE: [flexcoders] Re: Data grid with check box... How to get value

Title: Message
Joe.
 
Part of the Custom Cell Render Spec are four attributes that are available to the Cell Renderer. They are:
 
owner - the row the cell renderer instance is in.
listOwner - the container (data grid, list box, etc) the row is in
getDataLabel - function that will give you the column name the cell renderer is mapped to
getCellIndex - function that returns an object/structure/hash map of itemIndex (row), column index (pos in column array) and one other piece which I forget.
 
So, using this (they must be declared and are case sensitive to the spelling above) you can either dynamically get to the value of the current cell or static get to the value of a cell in that row. Here are some examples assuming you are mapping to the clickEvent of the checkbox that is in your cell renderer.
 
 
  function onValueChanged() : Void
  {
   var item = this.listOwner.dataProvider[getCellIndex().itemIndex];
   item[this.getDataLabel()] = checkbox.selected;
  }
or
 
  function onValueChanged() : Void
  {
   var item = this.listOwner.dataProvider[getCellIndex().itemIndex];
   item['myGoofyColumn'] = checkbox.selected;
  }
 
 
Best.

The data grid is populated from a data provider. It displays about 20 rows.
When I click on one of the check box I would like to be able to get a value from one of the cells in that row.
The data grid is a MXML component and the check box  is from a cell rendering action scripting file.
