Can you plese provide a fiddle to demonstrate the issue?

My guess is you don't set a unique recid for the added records.

thank you, found it it was because of the format of the response, it breaks if i send :
["status"=>"success", "total"=>$model->count(), "records"=>$model->all()]
but it works ok if i send only :
["status"=>"success", "records"=>$model->all()]

If you provide total it must represent the number of records available for the grid, not the number of records your current request returns.

E.g. your database contains 12,000 records and you are pulling them with limit 1,000, then total should always be 12,000 so the grid know that there are still records to pull from the server (during scrolling), until all 12,000 are present in the grid.

If you do not set total, or if you explicitely set total to -1, then you are basically telling the grid that you don't know how many records are there to pull from the server and the grid will not perform any load requests during scrolling (unless you manually set grid.last.xhr_hasMore, which is quite low-level).

If your grid has an url and you're "manually" adding records to the grid, you must update grid.total accordingly.

Only if your grid has no url set, then grid.add() will automaticall set this.total = this.records.length.

This is another very strange misbehavior that i don't know what could cause it ... any idea ?

Unfortunately, this bug has been around for some time already, but so far noone provided a fix.

See: Fast scrolling using infinite Scroll returns blank div without records

Even in w2ui 2.0 you can reproduce it in the infinite scroll demo: http://localhost:8080/demos#/combo/5

I am closing this issue, because the initial issue turned out to be not a bug and the second issue is a duplicate.

            if (event.target == 'add') {
                // w2ui.grid1.exportdata(this.records,'xls')
                w2ui.grid1.add({ recid:  w2ui.grid1.records.length + 1 + 'new'},true);
                w2ui.grid1.scrollIntoView(1);
            }
