I tested the issue in a simple sample of Client-Binding WebGrid and was unable to reproduce the issue on my local end.

I’m afraid that there is something that I missed during my attempt in order to replicate the issue. I’m willing to advice you further but in order to do so I would need you to elaborate on your specific scenario and possibly give me a running simple sample that I can use to observe the problematic behavior.

Just to confirm it with you. You need to start with very empty grid that has no rows, and just add a new row and don't refresh, and then try to have a button that call a client side function that just display the grid TotalRows.

Please send me your sample to compare it with my code.

I can not send you my code as its large project that has many dependencies. But here is snapshot:

                    alert("CheckNewRowsAddedToGrid: " + err.description);
                }

                return true;
            }

Please try to replicate this code at your sample.

I’m currently still investigating this issue and need more time to provide you with solution, suggestion, or sample.

I’ll get back to you as soon as possible.

Please try to obtain the total rows by using following snippet code.

WebGrid1.RootTable.Rows.length

I have tested that the "Rows.length" returns correct amount of total loaded rows of WebGrid. I also have tested the scenario where the Grid starts with empty grid (no rows).

Hope this helps.
