Hi 

I want to load the Normal view as a modal window when  kendo Toolbar button is clicked. Inside View I am calling Partial view as a whole form. (inside form there are another 2 partial views along with another inputs and 2 submit buttons).

But form is not loading as modal form instead it loads as normal form displaying url action route (GET request). Could you please help me what changes needed to get the ActionResult View loads as a Modal window.  when submit I need to execute POST method. but my GET method is not displaying correctly as a modal window.  

AddStructureNode View 

Partial View (_AddStructureNode)

SBScripts file Scripts

I call ShowDialog event when kendo toolbar button is clicked. so I have to load the form via ajax. 

Could you please show me where in my scripts has to be changed. I tried Content and Refresh methods but not successful. Thanks.

Using the SchedulerCustomEditor as a sample project I've created a project where the user can manage Events, both individual and recurring. I'm using EF6 to manage read/write to the database. My database has an Events table which has a many-to-many relationship with Categories and a many to many relationship with Locations (see attached). 

Add and Edit events (and their related categories) seems to work fine, recurring events and recurrence exceptions are getting created, updated properly, delete works fine until  a recurring event has a recurrence exception. An exception is thrown by Entity Framework: "Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded." Stepping through my delete function the calls to delete the recurrence exception event and it's parent occur almost simultaneously, I've notice similar in the Delete function in the SchedulerCustomEditor sample project:

        public virtual void Delete(MeetingViewModel meeting, ModelStateDictionary modelState)
        {
            if (meeting.Attendees == null)
            {
                meeting.Attendees = new int[0];
            }

            var entity = meeting.ToEntity();

            db.Meetings.Attach(entity);

            var attendees = meeting.Attendees.Select(attendee => new MeetingAttendee
            {
                AttendeeID = attendee,
                MeetingID = entity.MeetingID
            });

            foreach (var attendee in attendees)
            {
                db.MeetingAttendees.Attach(attendee);
            }

            entity.MeetingAttendees.Clear();

            var recurrenceExceptions = db.Meetings.Where(m => m.RecurrenceID == entity.MeetingID);

            foreach (var recurrenceException in recurrenceExceptions)
            {
                db.Meetings.Remove(recurrenceException);
            }

            db.Meetings.Remove(entity);
            db.SaveChanges();
        }

Can't say I really understand what is going on in the above function with the Attach calls. In the above function you are manually removing the records MeetingAttendees join table somehow, but in my scenario I have no access to these join tables.

My Delete function is:

        public virtual void Delete(EventScheduleViewModel evt, ModelStateDictionary modelState)
        {
            if (evt.Categories == null)
            {
                evt.Categories = new int[0];
            }
            if (evt.Locations == null)
            {
                evt.Locations = new int[0];
            }

            var entity = db.Events.Include("Categories").Include("Locations").FirstOrDefault(m => m.EventID == evt.EventID);

            foreach (var category in entity.Categories.ToList())
            {
                entity.Categories.Remove(category);
            }

            foreach (var location in entity.Locations.ToList())
            {
                entity.Locations.Remove(location);
            }

            var recurrenceExceptions = db.Events.Where(m => m.RecurrenceID == entity.EventID);

            foreach (var recurrenceException in recurrenceExceptions)
            {
                db.Events.Remove(recurrenceException);
            }

            db.Events.Remove(entity);
            try
            {
                db.SaveChanges();
            }

            catch (Exception e)
            {
                throw;
            }
        }

here's my Insert and Update functions which seem to be working ok:

        public virtual void Insert(EventScheduleViewModel evt, ModelStateDictionary modelState)
        {
            if (ValidateModel(evt, modelState))
            {
                if (evt.Categories == null)
                {
                    evt.Categories = new int[0];
                }
                if (evt.Locations == null)
                {
                    evt.Locations = new int[0];
                }

                var entity = evt.ToEntity();

                foreach (var categoryId in evt.Categories)
                {
                    var category = db.Categories.FirstOrDefault(s => s.CategoryID == categoryId);
                    if (category != null)
                    {
                        entity.Categories.Add(category);
                    }
                }

                foreach (var locationId in evt.Locations)
                {
                    var location = db.Locations.FirstOrDefault(s => s.LocationID == locationId);
                    if (location != null)
                    {
                        entity.Locations.Add(location);
                    }
                }

                try
                {
                    db.Events.Add(entity);
                    db.SaveChanges();
                }

                catch (Exception)
                {
                    throw;
                }

                evt.EventID = entity.EventID;

                foreach (var category in entity.Categories.ToList())
                {

                }

                foreach (var location in entity.Locations.ToList())
                {

How can I write my Delete function to remove recurring events that have recurrence exceptions? 

Thanks.

Hi Team,

I am facing problem in cancelling the grid with Inline Edit. Currently I have a grid that displays ApplicationName and AccessLevelvalues when we click edit and update this grid is working fine. But When I click edit and cancel it, my name field for any other rows will be getting replaced with ApplicationName of first row.. My code snippet is

<div style="position:relative;">
    <div style="float:left;position:relative; width:200px;">
        <label>UserName:</label>

Hi,

I am using a treeview to load data and on edit of a row, i would want to display a dropwon to choose data, i tried below to get the dropdown, but this does not give me a dropdown, please advise if this is possible or how to achieve this.

columns.Add().Field(e => e.InActive).Editor("StatusType").Width(100) ;

below is a partial view i added under the EditorTemplate folder

@model CodedValues
@(Html.Kendo().DropDownListFor(m => m)
        .AutoBind(true)
        .DataTextField("DisplayText")
        .DataValueField("KeyText")
        .DataSource(dataSource =>
        {
            dataSource.Read(read => read.Action("GetTypes", "my"))
                    .ServerFiltering(true);

Thanks in advance.

Assembly Reference "...\lib\KENDOUIMVC\2017.2.504.545\Kendo.Mvc.dll" was not updated properly. This usually happens when an assembly exists both in the GAC and in a local folder. Please, use the GAC reference instead.

How do I only use the GAC? And what is the GAC ;)

I am trying to use the events(e => e.Error("onError") in my grid that is ajax bound.  I keep getting a javascript error "onError" is undefined.  the grid is on a partial page that is loaded via ajax call. 

when I put the script in the main view the onError function runs event if there is no error thrown.  if I put it in a document ready function  I get undefined.

not sure what to do.
