                                  • I'm trying to set the top start time row in an ASPx scheduler, however as soon as I try to set it a JavaScript error fires:

                                    Error: this.cachedCells is null
                                    Source File: http://localhost:53497/[website name]/DXR.axd?r=8_27-Kt9m4
                                    Line: 201

                                    The javascript called is

                                    GetCell: function (containerIndex, index) {
                                      var hashCode = (containerIndex << 16) + index;
                                      var result = this.cachedCells[hashCode];
                                      if (!_aspxIsExists(result)) {
                                       var container = this.cellContainers[containerIndex];
                                       if (!_aspxIsExists(container))
                                        return null;
                                       var loc = container.GetCellLocation(index);
                                       if (_aspxIsExists(loc)) {
                                        result = this.table.rows[loc.row].cells[loc.column];
                                        this.cachedCells[hashCode] = result;
                                       }
                                      }
                                      return result;
                                     },

                                    the line with the error is highlighted to be

                                      var result = this.cachedCells[hashCode];

                                    This happens if there are no appointments or many appointments.

                                    Is there a setting I have missed out?

                                Hello Keith,

                                I am afraid that your approach is not quite correct. Please note that there is no guarantee that the ASPxScheduler client-side mode is completely initialized when the "$(document).ready()" JQuery event is raised. If you wish to ensure that a particular client control is initialized, you need to handle its ASPxClientControl.Init Event . I have updated your sample accordingly. Take a moment to look at the ASPxTextBox - How to attach the jQuery AutoComplete plugin example, where a similar topic is discussed in detail. I hope you will find this information helpful.

                                Thanks,
                                Alessandro.
