I can this now :)
There's a headerItems array property on the Adv DG that I can loop and
invoke a method to tell the headerRenderers to do something...
Here's some sample code to loop through all the headerItems but only invoke
the method if the header is of a certain Renderer...
for(var intLoop:int = 0; intLoop < advancedDataGrid.headerItems[0].length;
intLoop++){
if(advancedDataGrid.headerItems[0][intLoop] is HeaderFilterRenderer)
HeaderFilterRenderer(advancedDataGrid.headerItems[0][intLoop]).clearFilter();
}
Hope that helps someone...
