Scrollbar position and state saving

marianopeck

Hi guys.

My webapp in which I am using DataTables is very server side. I only render the table + DataTables in the client. In all my tables, I have a first column which is a checkbox to select/unselect rows. Say I have a table with vertical scroll. If I have scrolled up to the middle of the table, and I click on the checkbox to select the row, that is a request...so when it is rendered again, I come back to the top of the table.... of course.
So I was thinking.... does DataTables has something to offer me to solve this issue? Maybe there is something I can do with the state saving?

Thanks!

Currently the state saving and DataTables core does not remember the scroll position. However, the Scroller extra does, which might be an option for you?

Hi Allan. Scroller is not an option for me. Kind of complicate to explain, but I do have table controls before my HTML table so when scrolling down, I need to have not only the table always visible but also that div with the controls...and some other reasons. because of that, what I do need is to keep the header always visible, which DataTables does!! :) So I am using DataTables + FixedColumns which I also need.

But...if you tell me where I can look in Scroller, if it is not too complex, I can try to adapt it to normal/regular DataTables or directly for my tables???

I just need to fix all the alignment issues and I am ready to go to using DataTables in production :)

Thanks very much for this project!

This is how Scroller does it: https://github.com/DataTables/Scroller/blob/master/media/js/dataTables.scroller.js#L422 . And https://github.com/DataTables/Scroller/blob/master/media/js/dataTables.scroller.js#L610 .
