[CLOSED] MVC Grid panel takes long time to load and browser wants to end script

[AmitM]

Hello, I was following this thread:
http://forums.ext.net/showthread.php...-browser-hangs

But it does not help. I have a grid panel that is loading approximately 200 rows with 21 columns and it takes around 2 minutes to load/render. The actual data comes back within 2.4s. This is an edit grid with BeforeBind events which is probably why it takes so long. Any help optimizing would be appreciated.

Here is one of the column sets. There are 7 corresponding to each day of the week.

Html.X().Column()
                .Text("Monday")
                .Width(180)
                .Columns(
                    Html.X().ComponentColumn()
                        .Editor(true)
                        .DataIndex("MondayAttend")
                        .Width(60)
                        .Text("Attended")
                        .Listeners(ls =>
                        {
                            ls.BeforeBind.Handler = "if (e.record.get('Monday') == '') e.config[0].disabled = true";
                        })
                        .Component(Html.X().Checkbox()),
                    Html.X().ComponentColumn()
                        .Editor(true)
                        .DataIndex("MondayIn")
                        .Width(60)
                        .Text("In")
                        .Listeners(ls =>
                        {
                            ls.BeforeBind.Handler = "if (e.record.get('Monday') == '') e.config[0].disabled = true";
                            ls.Edit.Handler = "return editAttendenceFn(e.record, 'MondayIn', 'MondayOut');";
                        })
                        .Component(
                            Html.X().TextField()
                                .Plugins(Html.X().InputMask()
                                    .Mask("hi:mn aM")
                                    .AllowInvalid(true)
                                    .MaskSymbols(symbols =>
                                        {
                                            symbols.Add(new MaskSymbol() { Name = "h", Regex = "[01]" });

                                            symbols.Add(new MaskSymbol() { Name = "a", Regex = "[aApP]" });

                                        }
