I just installed the trial version and I can't seem to get the DatePicker to function as it does in the example.

I added the scripts and styles to the directories as instructed.

We are MVC3 so my _Layout file looks like:

<head>
<title>@ViewBag.Title</title>
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="../../Content/kendo/kendo.common.min.css"></script>
<script src="../../Content/kendo/kendo.default.min.css"></script>
<script src="@Url.Content("~/Scripts/kendo/jquery.min.js")"></script>
@*<script src="@Url.Content("~/Scripts/jquery-1.7.1.min.js")" type="text/javascript"></script>*@
<script src="../../Scripts/kendo/kendo.all.min.js"></script>
<script src="../../Scripts/kendo/kendo.aspnetmvc.min.js"></script>
</head>

Everything seems to function correctly but the display doesn't match and I'm seeing Unexpected Token errors in the kendo.common.min.css and kendo.default.min.css files.

Copy To Excel doesn't work in Batch Edit Mode

Hi There,

I am trying to Get 'Copy To Excel' to work in Batch Edit Mode. (GridEditMode.InCell)

I used the Telerik example below (razor/grid/editing) and added the two following lines to be able to copy to Excel:

.Selectable(selectable => selectable.Mode(GridSelectionMode.Multiple).Type(GridSelectionType.Cell))
.AllowCopy(true)

(Telerik\UI for ASP.NET MVC Q2 2015\wrappers\aspnetmvc\Examples\VS2013)

However, I am not able to copy to Excel.

Here is the code with the added lines in bold:

@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.ProductViewModel>()
.Name("Grid")
.Columns(columns => {
columns.Bound(p => p.ProductName);
columns.Bound(p => p.UnitPrice).Width(140);
columns.Bound(p => p.UnitsInStock).Width(140);
columns.Bound(p => p.Discontinued).Width(100);
columns.Command(command => command.Destroy()).Width(110);
})
.ToolBar(toolbar => {
toolbar.Create();
toolbar.Save();
})
.Editable(editable => editable.Mode(GridEditMode.InCell))
.Selectable(selectable => selectable.Mode(GridSelectionMode.Multiple).Type(GridSelectionType.Cell))
.AllowCopy(true)
.Pageable()
.Navigatable()
.Sortable()
.Scrollable()
.DataSource(dataSource => dataSource
.Ajax()
.Batch(true)
.PageSize(20)
.ServerOperation(false)
.Events(events => events.Error("error_handler"))
.Model(model => model.Id(p => p.ProductID))
.Create("Editing_Create", "Grid")
.Read("Editing_Read", "Grid")
.Update("Editing_Update", "Grid")
.Destroy("Editing_Destroy", "Grid")
)
)

Cheers,

Greg

Multiple Measures

I have a pivot grid against flat remote data source that is based on the demo but when I try to add multiple measures at runtime only the first measure is displayed. I can add additional measures from the configurator after page loads but I need the measures to show up on initial page load. Is this possible?

Model's Id value is not available in EditorTemplate

Hi,
I am working on Kendo Grid with MVC.Net. I am using CRUD operations with editor template. I am unable to get the model id value in editor template to figure out if it is a new record or existing record.

Here is my grid configuration which in cshtml file

@(Html.Kendo()
                          .Grid<TestRecord>()
                          .Name("Test")
                          .Columns(columns =>
                          {
                              columns.Bound(col => col.Id);
                              columns.Bound(col => col.Name);
                              columns.Command(command => { command.Edit(); command.Destroy(); });
                          })
                          .ToolBar(toolbar => toolbar.Create().Text("Add New Record"))
                          .Editable(editable => editable
                                                        .Mode(GridEditMode.PopUp)
                                                        .TemplateName("TestEditor"))
                          .Sortable()
                          .DataSource(dataSource =>
                          {
                              dataSource
                                        .Ajax()
                                        .ServerOperation(false)
                                        .Model(m =>
                                        {
                                            m.Id(a => a.Id);
                                            m.Field(a => a.Name)
                                        })
                                        .Read(read => read.Action("TestRead", "TestControl", new { id = this.Model.Id }))
                                        .Create(create => create.Action("TestRead", "TestControl"))

                              ;
                          })
                    )

My Editor is in separate file names TestEditor.cshtml. I am able to add/edit records without any issues. I need to update only one column if it is existing record. Hence I am hiding the remaining fields (other than the one I am updating) in the editor window. So I was wondering if I can use the model's Id column to figure out if it is a new record or not.

Here is my editor template : TestEditor.cshtml

@model TestRecord

// Render all the columns

@if (this.Model.Id > 0)
    {
    // only updated related column
    }

Regards,
Chen

Chart Tooltip position problem

I have a chart, which allows the user to click on a column, to refresh the chart with data from the next level in the hierarchy.

It works well, apart from the rightmost columns, on narrower displays. In these cases, the tooltip completely obscures the column, making clicking on them difficult.

I've attached an example image.

The chart definition is:-

@(Html.Kendo().Chart<Dashboard.Models.BarChartDataItem>(Model)

.Name((string)ViewBag.ChartName)

.Title((string)ViewBag.ChartTitle)

.Theme("bootstrap")

.Legend(legend => legend

.Position(ChartLegendPosition.Top)

.Visible(false)

)

.Series(series =>

{

series.Column(model => model.BarValue).Name("Actual").Tooltip(t=>t.Visible(true).Template("<div>Category:#=dataItem.AxisDescription#</br>Contribution: £#=dataItem.DisplayBarValue#</div>"));

})

.ChartArea(area => area

.Height(350)

.Background("transparent")

)

.ValueAxis(axis => axis.Numeric()

.Labels(labels => labels.Format("{0:N0}"))

.Title((string)ViewBag.Yaxis)

.AxisCrossingValue(0, int.MinValue)

.Line(line => line.Visible(false))

)

.CategoryAxis(axis => axis

.Labels(false))

.CategoryAxis(axis => axis

.Categories(model => model.AxisValue)

.Labels(labels => labels.Rotation(-45).Padding(5))

.MajorGridLines(lines => lines.Visible(false))

.Title((string)ViewBag.Xaxis)

)

.Events(e=>e.SeriesClick("seriesClick"))

.Tooltip(tooltip => tooltip

.Visible(true)

.Format("{0:N2}")

)

Is it possible to change the tooltip position? There don't seem to be any position options available.

In this case, displaying at the top of the column would be best, ensuring nothing is obscured.

Thanks

Read only Excel Spreadsheet into Spreadsheet control

Good afternoon.

Are there any example projects where the following is happening:

1. Initial Spreadsheet control is blank.

2. Upon selection of a an excel file .. loading it into the spreadsheet.

3. Spreadsheet is in read only format.

I have looked at the following demo...

http://demos.telerik.com/aspnet-mvc/spreadsheet/server-side-import-export

but it is preloading something that 1. I do not want, 2. i cannot even find the json file it is uploading.

I have tried to use the export function (to JSON) to export the initially loaded products json file and then reimport it using the code in the controller.... but it gives me serialization errors.

Thanks,

Corey

.Navigatable() option doesn't work with Batch Edit Mode & Foreign Keys

Hi Guys,

I have a grid that uses batch editing (GridEditMode.InCell).

This grid also uses a few Foreign Key columns.

If I use the .Navigatable() option, I can tab through the cells, but the foreign key columns don't show up as pick list anymore but as integer.

I believe the following example would have the same issue if it had a foreign key column.

http://demos.telerik.com/aspnet-mvc/grid/editing

is this a bug with MVC Grid or am I missing an option ?

Cheers,

Greg

Severe rendering problems

For some time, I've noticed some severe rendering problems when using Kendo numeric/integer text box widgets. Here's the scenario:

Currently, I'm using the latest version of everything (Windows 10 with update 1511, VS 2015 Update 1, latest Kendo), although the problems I'm seeing date back to Window 8/8.1 and VS 2013.

I've got an MVC app using Bootstrap.

In the particular case that I'm working on right now, I've got a form inside a dialog box (Kendo Window widget) that uses a number of different Kendo widgets for input (TextBox, DropDownList, IntegerTextBox).

When I use the IntegerTextBox (or other numeric) widget, rendering consistently just goes all to hell in the dialog box. Spinners disappearing are the least of it. A lot of the time, all the other HTML elements in the dialog box are being overlaid by something. When I move the mouse over various controls, they sometimes appear and sometimes disappear. Clicking on one of the numeric text boxes tends to make everything else disappear. If I remove all numeric text box widgets from the form, the problems disappear completely. Removing the form itself has no impact. Removing validators has no impact.

This occurs in both IE and Edge browsers, but only on my desktop system, never on my laptop or my Surface Pro 3. My desktop system has a second generation i7-2600 with Intel HD Graphics 2000. My laptop has a fourth generation i7-4700HQ with Intel HD Graphics 4600. My Surface Pro 3 has a fourth generation i5-4300U with Intel HD Graphics 4400. I don't see these types of problems when I surf around the web, just in the apps I'm developing with Kendo.

I'm almost at the point of having to buy another desktop computer with a newer processor/graphics just so I can do my work. The problem with that, as my wife wisely points out, is that my customers may run into this problem with the deployed app. Judging by other forum threads, other developers are seeing similar things, but no one seems to have been able to come up with an example that you can duplicate. I suggest you get a system similar to my desktop machine and try it on that. I think the problem is related to the interaction between the Intel HD Graphics 2000, Windows 8x/10, and Kendo. Intel has essentially dropped support for their HD Graphics 2000/3000 for version of Windows greater than 7 although, obviously, Windows 8x/10 installs and seems to otherwise work on those systems.
