[flexcoders] dynamic number of datagrid columns

[t_msreddy]

HiI need to implement a datagrid based on user input. User input determines the number of datagrid columns.Can you please tell me how to do this? In all the examples I have seen the grid columns are static though data is rendered through data provider like this:<mxataGrid id="datagrid1" width="100%" height="80%" dataProvider="{dp}"  rowHeight="100">      <mx:columns>        <mx:Array>          <mxataGridColumn headerText="Name" columnName="name" editable="false"/>          <mxataGridColumn headerText="City" columnName="city" editable="false" />		  <mxataGridColumn headerText="Birthday"  cellRenderer="GridCellRenderer"  />		  <mxataGridColumn headerText="Favorites" columnName="combodata" editable="true"  />		  <mxataGridColumn headerText="Delete"  columnName="candelete" editable="true"  />        </mx:Array>      </mx:columns>	  	      </mxataGrid>
 
here you have mxataGridColumn  tags which render the columns. I need to implement a datagrid which has dynamic number of 
columns.
 
Please help me.
