And call this function like this “setTimeout(renderChildren,250);” at the end of “initComponent()” & “dateChange()” events.

public function renderChildren():void
{
var obj:Object;

for(var i:int=0;i<dateGrid.numChildren;i++)
{
obj=dateGrid.getChildAt(i);
if(obj.hasOwnProperty("text"))
{
if(obj.text != "" && obj.text != "S" && obj.text != "M" && obj.text != "T" && obj.text != "W" && obj.text != "T" && obj.text != "F" && obj.text != "S")
{
obj.enabled=false;
}
}
}
}
