Set DataGrid headerRenderer dynamically

[Brian McCairn]

Hi

Flex newbie so be gentle.

I've got a function to create a new colummn in a grid ...

             private function addBlankDataGridColumn(dataField:String):void
            {
                var dgc:DataGridColumn = new DataGridColumn(dataField);
                dgc.headerText="hi2";
                dgc.headerRenderer="VDGHeader";
                var cols:Array = musicDatagrid.columns;
                cols.push(dgc);
                musicDatagrid.columns = cols;
            }

This works fine apart from the line

dgc.headerRenderer="VDGHeader";

I can set the headerRenderer="VDGHeader" as a parameter in predefined columns and it works fine, but in the function above it causes the following error

1067: Implicit coercion of a value of type String to an unrelated type mx.core:IFactory.

I've tried

dgc.setHeaderRenderer("VDGHeader");

but no luck.

Can you set the headerRenderer dynamically?

Thanks

Brian

I found the following seems to do the trick

dgc.headerRenderer= new ClassFactory(VDGHeader);
