Hi,

After I updated from 2015.3.1111 trial to 2016.2.714 (licensed) my grid incell edit is not longer working.I can select the row with the checkbox, uncheck it, but as soon as I leave the cell, it is again checked. I assume that the change is not being applied to the underlying model (and I see "Ja" in the cell) ...

Here is my grid:

@(Html.Kendo().Grid<ModelLayer.Bild>()
    .Name("bildergrid")
    .HtmlAttributes(new { style = "height:600px;" })
    .Columns(columns =>
    {
        columns.Bound(p => p.BildBase64).Title("").ClientTemplate("<img class='gallery' rel='bilder' style='width:100px' href='data:image/png;base64, #: BildBase64#' src='data:image/png;base64, #: BildBase64#'>").HtmlAttributes(new { style = "max-width:100px;width:100px;" }).Width(100);       
        columns.Bound(p => p.Internet).Width(30).ClientTemplate("#= Internet ? 'Ja' : 'Nein' #");
        columns.Bound(p => p.Expose).Width(30).Title("Mail").ClientTemplate("#= Expose ? 'Ja' : 'Nein' #");
        columns.Bound(p => p.Drucken).Width(30).ClientTemplate("#= Drucken ? 'Ja' : 'Nein' #");
        columns.Bound(p => p.Dateiname).Width(200);
        columns.Bound(p => p.Groesse).Width(80).Visible(false); ;
        columns.Bound(p => p.Pixel).Width(80).Visible(false);
        columns.Bound(p => p.Position).Width(100);
        columns.Bound(p => p.Pfad).Visible(false);
    })
        .DataSource(dataSource => dataSource

            .Ajax()
            .PageSize(0)
            .Read(r => r.Action("Bilder_Read", "Immo", new { immobilieId = "728" }))
            .ServerOperation(false).Model(model => model.Id(p => p.Id))
         )
         .Editable(e => e.Mode(GridEditMode.InLine))
        .Resizable(i => i.Columns(true))
        .Selectable(e => e.Enabled(true).Mode(GridSelectionMode.Single))
        .Scrollable()
        .AutoBind(false)
        //.ToolBar(t=> t.Create())


)

I'm having a problem with a hierarchical grid: when I run my solution, the date doesn't show in the correct format, and because of that I can't see the child grid. But when I deploy the application, it does show correctly but it has an error, and I can't debug to solve it.

Here is the grid:

@(Html.Kendo().Grid(Model)
        .Name("OperacionesOCTVigentes")
        .DataSource(dataSource => dataSource
        .Ajax()
            .Read(read => read.Action("OperacionesOCTVigentes_Read", "Operaciones")
            .Data("ParametrosOCTVigentes"))
        .PageSize(30)
        .Aggregates(a =>
            {
                a.Add(p => p.Compras).Sum();
                a.Add(p => p.Ventas).Sum();
                a.Add(p => p.Neto).Sum();
                a.Add(p => p.MTM).Sum();
            })
        )
        .Columns(columns =>
        {
            columns.Bound(foo => foo.fecha_venc).Title(Global.Fecha).Format("{0:dd/MM/yyyy}").HtmlAttributes(new { @class = "grillaFecha" });
            columns.Bound(foo => foo.espe_codigo).Title(Global.Especie).HtmlAttributes(new { @class = "grillaTexto" });
            columns.Bound(foo => foo.clas_codigo).Title(Global.Clase).HtmlAttributes(new { @class = "grillaTexto" });
            columns.Bound(foo => foo.Compras).Title(Global.Compras).Format("{0:N}").HtmlAttributes(new { @class = "grillaNumero" }).ClientFooterTemplate("#= kendo.format('{0:N}', sum)#");
            columns.Bound(foo => foo.Ventas).Title(Global.Ventas).Format("{0:N}").HtmlAttributes(new { @class = "grillaNumero" }).ClientFooterTemplate("#= kendo.format('{0:N}', sum)#");
            columns.Bound(foo => foo.Neto).Title(Global.Neto).Format("{0:N}").HtmlAttributes(new { @class = "grillaNumero" }).ClientFooterTemplate("#= kendo.format('{0:N}', sum)#");
            columns.Bound(foo => foo.MTM).Title(Global.Capital).Format("{0:N}").HtmlAttributes(new { @class = "grillaNumero" }).ClientFooterTemplate("#= kendo.format('{0:N}', sum)#");
        })
        .ClientDetailTemplateId("template")
    )

And this is the child grid:

<script id="template" type="text/kendo-tmpl">
    @(Html.Kendo().Grid<SGMTrade.DAL.ViewModels.OperacionesOCTPorFecha>()
                .Name("grid2_#=row#")// "grid2_#=fecha_venc#
        .DataSource(dataSource => dataSource
            .Ajax()
            .PageSize(10)
            .Read(read => read.Action("OperacionesOCTPorFecha_Read", "Operaciones", new { fecha = "#=fecha_venc#", especie = "#=espe_codigo#", cliente = @ViewBag.cliente, clase = "#=clas_codigo#" }))
        )
        .Columns(columns =>
        {
            columns.Bound(o => o.oper_numero).Title(Global.NumeroOperacion)
                .ClientTemplate("<a href='\\\\\\#' onclick=\"showDetails('\\#=oper_numero\\#')\">\\#=oper_numero\\#</a>").HtmlAttributes(new { @class = "grillaNumero" });
            columns.Bound(o => o.oper_forigen).Title(Global.FechaOrigen).Format("{0:dd/MM/yyyy}").HtmlAttributes(new { @class = "grillaFecha" });
            columns.Bound(o => o.espe_codigo).Title(Global.Especie).HtmlAttributes(new { @class = "grillaTexto" });
            columns.Bound(o => o.clas_codigo).Title(Global.Clase).HtmlAttributes(new { @class = "grillaTexto" });
            columns.Bound(o => o.clie_nombre).Title(Global.Cliente).HtmlAttributes(new { @class = "grillaTexto" });
            columns.Bound(o => o.tope_suma).Title(Global.CompraOVenta).HtmlAttributes(new { @class = "grillaTexto" });
            columns.Bound(o => o.oper_monto).Title(Global.Capital).Format("{0:N}").HtmlAttributes(new { @class = "grillaNumero" });
            columns.Bound(o => o.oper_plazo).Title(Global.Plazo).HtmlAttributes(new { @class = "grillaNumero" });
            columns.Bound(o => o.Fecha_Vence).Title(Global.FechaVence).Format("{0:dd/MM/yyyy}").Hidden(true).HtmlAttributes(new { @class = "grillaFecha" });
            columns.Bound(o => o.precio_transf).Title(Global.PrecioTransferencia).HtmlAttributes(new { @class = "grillaNumero" });
            columns.Bound(o => o.spread).Title(Global.Spread).HtmlAttributes(new { @class = "grillaNumero" });
        })
        .Pageable()
        .Sortable()
        .Selectable()
        .Scrollable(s => s.Height(100))
        .Resizable(resize => resize.Columns(true))
        .Reorderable(reorder => reorder.Columns(true))
        .Filterable(ftb => ftb.Mode(GridFilterMode.Menu))
        .ToClientTemplate()
    )

</script>

In the first attached file it can be seen how the parent grid displays, and in the second one it can be seen that since the date format is incorrect, it can't perform the desired action (show details from database).

What can I do? Thanks in advance

Hi everyone,

In a page I have several charts/grids that takes a while to load (because the data are manipulated before the rendering), so there is no issue with the Telerik component here.
My issue is: I'm on the page and the charts/grids are loading, if I click on a link that redirect to an other page of my application and if the charts/grids are still loading I'm not directly redirect to the other page. I think that the page is waiting for the charts/grids to be 100% rendered before redirecting me to the other page. So, sometimes, I need to wait for about 10-15 seconds (because of the manipulation of data server side) to be redirected to the other page.

Is there any solution to stop the rendering of the charts/grids when I click on a link ?

Thank you in advance for your response.

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, 

I have a problem  with validation message for DatePicker in UI for ASP.NET MVC. 

Property in model:

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".

The problem is in the content of the validation message. Message in my model is "Please enter a valid date. - TEST" but message in html is "The field FromDateTime must be a date." 

I want to create localization of this message and change its content. How can I do it?

Thank you for your advice.

Thank you.

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
