I found how I can do it. thank you
do you know whether the performance issues of ExtendedDataTable will fix for Release 4.0?????
We will work on it for sure Look for 4.0 ALPHA 2 when it will be released. It will already contains rewritten tables(with some functionality not implemented for ALPHA but you will be able to check it in general). We just not spent much time on this component as it was community contributed one. And now moving to 4.x is best time for us to revise and redesighn the component considering performance usability and so on.
