I am doing grid.store.reload() to do the actual refresh. Is that what I should be using?

yes, that's the common way of reloading the store and automatically refresh the (live)-grid. i guess you need to create an event listeners prior to store-reload to remember the scrolling position.

Is it possible to make LiveGrid work with Locking GridView extension, an example of locking grid can be seen at
http://www.extjs.com/deploy/dev/exam...king-grid.html

I'm having a problem with maintaining selections. I'm using revision 62 against Ext 3.0.0 final.

When rows are selected, and the grid is scrolled far enough to make a request, then scrolled back up again (causing another request), the rows are no longer selected.

Examining the records as they pass through replaceSelections(), I noticed that the ids of the records were incremented, not decremented. That is, the first request after scrolling down yielded records ext-record-101 through ext-record-200. The request made upon scrolling back up returned records ext-record-201 through ext-record-300, when it should have returned records somewhere between ext-record-0 and ext-record-100. Since that id is used to compute selection status, I figured that was probably the problem, but can't figure out anything I might have done to cause it.

I added a simple log statement inside the for block in replaceSelections(), line 2404 of livegrid-all-debug.js:

        for (i = 0, len = records.length; i < len; i++) {
            rec = records[i];
            id  = rec.id;
            
            // Debug statement
            console.log(rec.id);

            if (assigned.indexOf(id) == -1 && selections.containsKey(id)) {
                console.log(rec);
                selections.add(rec);
            }
        }

bufferSize is 100, nearLimit is 50.

Can others reproduce this? Have I neglected to pass some config option in somewhere?

Hi iancmcc,

Im facing the exact same issue, were you able to figure this out?

Thanks!

I am working on merging LiveGrid with Column lock extension but struck at the point where in adjustBufferSize() code relies on first row that should have already been added to the grid but in my case for some reason its not getting added. Can somebody please tell me where the first row is added?

[ItsMee]

Correction, actually the method which checks for first row is adjustVisibleRows()

Has anyone tried livegrid .041 & Ext 3.1 with large number of columns. I just changed the demo which is available on ext-livegrid website to work with more than 20 columns. The grid displays fine but then if I scroll to the right and then click on one of the cells then suddenly headers and rows get out of sync. Is there any demo of live grid with more than 20 columns. Please let me know if you have any suggestions for fixing this issue.
Thanks.

Last question for now:
I tried to use the grid with checkbox selection (by changing the superclass of Ext.ux.grid.livegrid.RowSelectionModel to Ext.grid.CheckboxSelectionModel).
That also only _almost_ works: The "(De)Select All" checkbox in the column header only acts on the currently buffered rows.
Any idea how to make it work on _all_ rows?

Did you ever got this working?

hey there, CheckboxSelectionModel-Support will be available in the upcomin release!
