Is there any way to toggle tooltips for different tasks in the Gantt based on a field set in the model? We have some tasks that require tooltips, and I made a template for them that displays some model fields. When a top-level (i.e., summary) task does not contain children, I've added a task that displays No Tasks as its title (per user requirements). It is for these 'No Tasks' tasks that I would like to completely toggle off tooltips. Any suggestions?

So I've got a grid that I believe is all set up correctly. I've confirmed that the data is coming through, and I've even checked that the AJAX call returns a success with the "ToDataSourceResult" JSON data.

Unfortunately, the only problem is that the data doesn't display. This seems to only be an issue on read, as update, create and delete all work. Just can't retrieve the list of all items afterwards.

My controller action looks like this: 

public IActionResult Blog_Read([DataSourceRequest] DataSourceRequest request)
        {
            var blogs = _blogService.GetPosts().Select(post => new BlogPostModel
            {
                Id = post.Id,
                Title = post.Title,
                Author = post.Author,
                ShortDescription = post.ShortDescription,
                Contents = post.Contents,
                LastSaved = post.LastSaved,
                Published = post.Published,
                PublishedOn = post.PublishedOn
            });
            var result = blogs.ToDataSourceResult(request);
            return Json(result);
        }

And my Grid View looks like this:

@(Html.Kendo().Grid<BlogPostModel>()
            .Name("grid")
            .Columns(columns =>
            {
                columns.Bound(p => p.Title);
                columns.Bound(p => p.Author).Width(120);
                columns.Bound(p => p.LastSaved).Width(120);
                columns.Bound(p => p.Published).Width(120);
                columns.Command(command => { command.Edit(); command.Destroy(); }).Width(250);
            })
            .ToolBar(toolbar => toolbar.Create())
            .Editable(editable => editable.Mode(GridEditMode.PopUp))
            .Pageable()
            .Sortable()
            .Scrollable()
            .HtmlAttributes(new { style= "height:600px;"})
            .DataSource(dataSource => dataSource
                .Ajax()
                .PageSize(20)
                .Events(events => events.Error("error_handler"))
                .Model(model => model.Id(p => p.Id))
                .Create(update => update.Action("Blog_Create", "BlogAdmin"))
                .Read(read => read.Action("Blog_Read", "BlogAdmin"))
                .Update(update => update.Action("Blog_Update", "BlogAdmin"))
                .Destroy(update => update.Action("Blog_Delete", "BlogAdmin"))
            )
            .Deferred()
        ) 

The correct JSON is returned, no javascript errors in the console, so I'm a little confused as to what this could be. Any help would be greatly appreciated.

The View is rendered empty as if there is an exception when Editor is generated.
The DropDownList is not populated in the Editor.
If the Bind is commented in the Editor, the view is rendered and the Editor display the dropdownlist of course with no content.
So The problem comes from the Bind.
Any Help will be appreciated

Hello,

Part of my cshtml file:

This is part of the html page which is generated from the cshtml file:

Image of the part of the html page from webbrowser is in file "datepickerError.png".

Hi,

I'm having a problem with the aggregates on my server-bound grid. Here's my code:

I've attached a screenshot of the rendered grid. The totals are in the wrong columns for the parent grid, and both parent and child have sums that are zero.

Thanks

Hi, what am I doing wrong here?  I can get the data out properly, but it won't sort.  It seems to work the same in both MVC (razor) and in javascript.
It should have all the names (Resource) in alpha order... but it seems to be sorting by the PriorityColorString

MVC

javascript:

Hello,

We are currently developing with the Diagram control.

I have a question, how do we customize the ribbon's toolbar above it? (see screenshot)

I am reading conflicting tutorials about this, some say it is a WIDGET, but then i read toolbar in some places.

Is there an example somewhere how to, for example add a button with an customized onclick?
