I'd do it somethign like this:
// Datagrid Filter
public function processFilter(item:Object):Boolean
{
var result:Boolean=true;
var pattern:RegExp = new RegExp("^"+userIDFilter.text,"i");
if(item.UserID != null && !item.UserID.match(pattern))return false;
if(item.FirstName != null && !item.FirstName.match(pattern))return false;
ect
return true;
}
That what you are looking for?
