Thanks Matt, I might give this a try. I ended up using something like this
which also works:


For (var i:Number=0; I < dg.rowcount; i++)
{

      For (var j:Number=0; I < dg.columns.length; j++)
      {
            myHTML += dg.rows[i].cells[j].value;
      }
}


As I said, this works and makes sense. It reads what it is in the cell and
not what it is in the dataprovider for the same position. However, it is
not documented I believe. I found something similar in the Macromedia
forums. Any comments?

Thanks,
-Oscar.

How about something like this?

For (var i:Number=0; I < dg.dataProvider.length; i++)
{
  var cells:Array = [];
  var item:Object = dg.dataProvider.getItemAt(i);
  for (var c:Number=0; c < dg.columns.length; c++)
  {
    var col:mx.controls.gridclasses.DataGridColumn = dg.getColumnAt( c );
    if (c.labelFunction != undefined)
    {
      cells.push(c.labelFunction(item));
    }
    else
    {
       Cells.push(item[c.columnName]);
    }
  }
  //do something with cells to build your HTML
}

Matt

Let me reformulate my question. Usually you can use selectedItem.
columnName   to read the value of a row/column of a datagrid. This seems to
work fine as shown in the Flex Sample Explorer ( example below).  But how
can you read the value of a computed column that was added in addition to
the columns returned by the dataprovider?   When I trace the selectedItem
or getItemAt, I only get the dataprovider data and nothing else.

<mx:DataGrid id="dg" width="100%" height="100%"
        dataProvider="{employeeModel.employee}">
        <mx:columns>
            <mx:Array>
                <mx:DataGridColumn columnName="name" headerText="Name"/>
                <mx:DataGridColumn columnName="phone" headerText="Phone"/>
                <mx:DataGridColumn columnName="email" headerText="Email"/>
<!--         How can I read this?   -->
                <mx:DataGridColumn columnName="myComputedColumn"
headerText="All" labelFunction="cocanateAll"/>
<!--   No part of the dataprovider, but shows OK   -->
            </mx:Array>
        </mx:columns>
    </mx:DataGrid>

    <mx:Form>
        <mx:FormItem label="Name">
            <mx:Label text="{dg.selectedItem.name}"/>
        </mx:FormItem>
        <mx:FormItem label="Email">
            <mx:Label text="{dg.selectedItem.email}"/>
        </mx:FormItem>
        <mx:FormItem label="Phone">
            <mx:Label text="{dg.selectedItem.phone}"/>
        </mx:FormItem>
<!--         How can I read this?   -->
        <mx:FormItem label="">
            <mx:Label text="{dg.selectedItem.myComputedColumn}"/> <!--
This doesn't work  -->
        </mx:FormItem>
<!--           -->


Thanks,
    </mx:Form>

Reading the displayed value in a DataGrid - How to

I am using labelFunction for a column in a datagrid. How can I read the
displayed value and not the real value directly from the dataGrid?

I am also wondering how to get values from the DataGrid in general. I need
to render the DataGrid to a HTML table, I mean, read columns and rows from
the dataGrid and have a string with the HTML syntax. I could not find
anything such as getRow, and then read each column. So I am selecting each
Row and then using the selectedItem property.

I know that I could use the function executed in labelFunction to
reproduce the displayed value, but I am actually trying to extend the
DataGrid class and add a method called getHTMLString for example. This
would require to be agnostic of whether the column has a labelFunction or
not.

Any ideas?

Thanks.
