Re: [flexcoders] Reading the displayed value in a DataGrid - How to

[Ramu p]

Hi,
 
U guess there is a mistake in the following line that you used.
 
  <mx:DataGridColumn columnName="myComputedColumn"headerText="All" labelFunction="cocanateAll"/>
The above must be:
  <mx:DataGridColumn columnName="{myComputedColumn}"headerText="All" labelFunction="cocanateAll"/>
 
Pls correct me if any worngs!
 
Thanks.

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 howcan you read the value of a computed column that was added in addition tothe 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>

I am using labelFunction for a column in a datagrid. How can I read thedisplayed 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 fromthe dataGrid and have a string with the HTML syntax. I could not findanything 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 toreproduce the displayed value, but I am actually trying to extend theDataGrid class and add a method called getHTMLString for example. This
would require to be agnostic of whether the column has a labelFunction ornot.Any ideas?Thanks.---------------------------------------------------------------------------This e-mail message (including attachments, if any) is intended for the use
