[flexcoders] Show\Hide Column in DataGrid

[sanjaypmg]

Hi All,

I am facing an Error while making Grid columns visible\Invisible at 
runtime.

I have made a function showHideColumns in my application which accepts 
2 arrays as parameters. One is "colNameArr" Which has all the column 
names of GRID and another one is "colStatusArr", which has TRUE or 
FALSE corresponding to that partifular column.

When I call the method "showHideColumns" It is making the column 
visible\invisible but showing an ERROR also Which is "Cannot Create a 
Property on String".

How Can I remove that error? pls suggest me something. the function is 
given below:


******************  FUNCTION   *************************************
public function showHideColumns(colNameArr:Array, 
colStatusArr:Array):void{

   for(var i:int=0; i<colStatusArr.length; i++){                

      this[colNameArr[i]].visible = colStatusArr[i];

                                
   }
                        
} 
*******************************************************

Thanks in Advance,
