Davis, thanks for the post ...
In your example Are you using the pagination also?
How do you maintain sorted data between the pages??
I have implemented sorting almost like what you have done....
but i am facing problem in maintaining the sorted data with the
pagination.
say i have 10 rows and i make it 5 rows per page.Hence i get 2 pages
now the first page is sorted and fine .when i click the button to go
to next page the control goes to the below function in the
DataSourceTableModel
public void requestRows(final Request request,
final Callback<Student> callback) {
// here we have method to create the new data.. how do we stop this?
since i have 5 more rows of old sorted data yet to be rendered
or
if we have hard coded array list data it will again fetch the data as
per page size ie first 5 data but i need data from 6 to 10 .
}
pls share u r thoughts on this.....
Thanks
Chythanya
