Hi Group,
I have a dataset that is populated with XML, then filtered depending on a
value in a combobox which is populated from another dataset.
My client walked in , looked at the result, and decided that he would like
it to be further filtered according to a second combobox...
Can the filterFunc function handle more than one argument?
The second combobox has fixed values.
Thanks
Don
