Hi
I am trying to return serverside data to datatable
first if I put
"scroller": true
then there will bee multiple fetch but if i put
"scroller": {
"displayBuffer": 75,
"loadingIndicator": true,
"serverWait": 50
}
I will have only 1 fetch done
In the xhr header, datatable will send for the first record
start:0
length:9
so I return from record 1 to 9
second
start:6
length:108
so I return from record 7 to 114
third
start:34
length:108
so I return from record 35 to 149
My question here is why length of 108 when datatable is using only a portion of it
I'm I following the wright logic or is it something else that I do not know
Thank in advance

Scroller will request more than just the rows shown to allow for smoother scrolling. You've set the
displayBufferoption to 75 which means that it should request 75 * the number of rows that can be shown!This old blog post that introduces Scroller shows a diagram that demonstrates how Scroller works. Looks like there is an error loading the data on the page, but the description text is still correct.

Hi Allan
I understand that
My biggest problem is when I code
"scroller": { "displayBuffer": 75, "loadingIndicator": true, "serverWait": 50 }instead of
"scroller": trueit does not seam to work
I fetch only 1 draw even if I have a lot more
Thanks
If you could post a link to a test case showing the issue I can take a look into it.
