Is there a way to allow templates to use an "image/jpg" (byte) type in a model to populate an <img>
I have fooled around with a couple of ways with no real way forward.

Many Thanks

DatePicker in BatchEdit Grid on iPad

Hello,

we are using DatePickers / TimePickers in a batch editable grid. Our problem is: if i edit such a cell on the iPad it immediately opens the keyboard. If i use a DatePicker standalone it just opens the keyboard if I click on the TextBox of the control. If I just click on the calendar-symbol it opens only the calendar - no keyboard.

What I'd like to have is the same behaviour as a standalone DatePicker. When I click in the cell of my grid it just should open the calendar and only if I click on the TextBox of my DatePicker-control it should show the ipad-keyboard.

Hope you understand what I mean. I know this is a very special case but if you have any solution for this I would be very happy. Hopefully you can help me :)

Best regards,
Mathias

[Solved] I have an issue with ListView mvc

The following code does not create list at all:

@(Html.Kendo()

.ListView<ReportTypeViewModel>()

.Name("listView")

.TagName("ul")

.DataSource(ds => ds.Read(read => read.Url("/api/ReportApi/List").Type(HttpVerbs.Get)))

.ClientTemplateId("templateReportList"))

When I pass list to the constructor by:

.ListView<ReportTypeViewModel>(types)

this is working.

Url "/api/ReportApi/List" is MVC 4 web api.

However when I checked not MVC version of list the following code works:

function initList() {

$("#listview").kendoMobileListView({

template: "<a><span>${data.Name}</span></a>",

dataSource: new kendo.data.DataSource({

transport: {

read: "/api/ReportApi/List",

type: "json"

},

}),

style: "inset"

});

}

Above is mobile list view. But web also is working without problem. The only issue I have is MVC wrapper.

UPDATE:
I've posted this in wrong thread - could you please move it to proper one?

Index Out Of Range Exception in GridBuilder

Hi ,
I've developed a few lines of code with ASP.NET MVC wrappers of Telerik
A Customer Entity with ID , Name , Rate
Entity Framework Code First Context
A Controller with this code :

public ActionResult Index()

{

return View();

}

public ActionResult Customers([DataSourceRequest] DataSourceRequest request)

{

var customers = Context.Customers.ToDataSourceResult(request);

return Json(customers);

}

and a view with this code

@(Html.Kendo().Grid<Customer>()

.Name("CustomersGrid")

.Columns(columns =>

{

columns.Bound(c => c.ID).Groupable(false);

columns.Bound(c => c.FName);

columns.Bound(c => c.LName);

columns.Bound(c => c.Rate);

})

.Groupable()

.Pageable()

.Sortable()

.Scrollable()

.Filterable()

.DataSource(dataSource => dataSource.Ajax().Read(read => read.Action("Customers", "Customer"))

)

when render of view finishes at the end of @HTML.Kendo
I give this exception

Entity with associations; grid not displaying.

Hello,

I have an entity with regular properties as well as navigation properties.

The grid fails to load anything If any item in the whole DataSourceResult has any of navigation properties populated (if any entity has has any other entity associated with it).

I do not want to use any of the data from the navigation properties in the grid, I want to only use the regular properties.

Controller:

public ActionResult GetPeopleData([DataSourceRequest] DataSourceRequest request)

{

return Json(db.People.ToDataSourceResult(request));

}

View:

@(Html.Kendo().Grid<Models.Person>()

.Name("PeopleGrid")

.Columns(columns =>

{

columns.Bound(p => p.Id).Groupable(false).Visible(true);

columns.Bound(p => p.LastName);

columns.Bound(p => p.FirstName);

})

.Selectable(selectable => selectable.Mode(GridSelectionMode.Single))

.DataSource(dataSource => dataSource

.Ajax()

.Read(read => read.Action("GetPeopleData", "People"))

)

.Events(events => events.Change("PeopleGrid_RowSelected"))

)

If I clear all the associated tables and just have the people table populated the grid works fine.

Anyone have any ideas?

how do I display status response next to file list?

I have an Upload control that works fine, except I want to show the user if their file was accepted or not. I've followed the Documentation example to show the alert message, but I don't want an alert popup - I want to display the message next to the file in the same way that the Cancel/Uploading buttons appear in the example, and the check mark appears. However, I'm extremely new to jQuery and don't understand how to go about that. It also doesn't make sense to me that no matter what I send, it is regarded as a success...
View:

@model Datamart.Models.FileSpec

@{

ViewBag.Title = "Upload Datamart File";

}

<h2>Upload Excel File</h2>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

File must be less than 16MB and must be an Excel spreadsheet<br />

@(Html.Kendo().Upload()

.Name("files")

.ShowFileList(true)

.Multiple(true)

.Messages(msg => msg

.StatusUploaded("Response Status Goes Here?")

.StatusFailed("statusFAiled")

.StatusUploading("Uploading")

.Async(a => a

.AutoUpload(true)

.Save("Save","FileUpload")

)

.Events(e => e

.Success("onSuccess")

)

<div>

@Html.ActionLink("Back to List", "Index")

</div>

<script type="text/javascript">

function onSuccess(e) {

alert("Status: " + e.response.status);

}

</script>

Controller:

public ActionResult Save(IEnumerable<HttpPostedFileBase> files)

{

foreach (var file in files)

{

string UPLOADSDIRECTORY = Server.MapPath("~/App_Data/uploads");

// Verify that the user selected a file

if (file != null && file.ContentLength > 0)

{

// extract only the filename

var fileName = Path.GetFileName(file.FileName);

/* check the first three letters of the extension for xls - there are far too many endings for Excel to check all of them */

if (Path.GetExtension(file.FileName).Substring(1, 3) == "xls")

{

// store the file inside ~/App_Data/uploads folder

var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);

FileInfo fInfo = new FileInfo(path);

if (!(fInfo.Exists))

{

file.SaveAs(path);

var dataFile = new FileSpec { FileName = fileName };

db.FileSpec.Add(dataFile);

db.SaveChanges();

// if successful, then redirect to the Edit page so the user can fill in the tab name while it's still fresh in their mind

return Json(new { status = "OK" }, "text/plain");

}

// TODO: redirect to error message because the file already exists

return Json(new { status = "Overwritten" }, "text/plain");

}

// TODO: redirect to error message because the file was not an Excel file (as determined by extension)

return Json(new { status = "Rejected" }, "text/plain");

}

// default to Default status

return Json(new { status = "Default" }, "text/plain");

}

Direction not implemented?

I don't see the dirction property on the MVC wrapped menu, do we lose functionality by using the MVC wrappers? If not, how do I specify the direction the menu will open?

Thanks!

Delete confirmation is shown although it is deactivated

Hello,

I think I found a new bug. We deactivated the delete confirmation with the DisplayDeleteConfirmation-property. Works perfectly for the delete-button in the grid. Only problem: When I delete a row manually the confirmation is still shown.

Here my code:

function myFunction()

{

var gridChoosenValues = $('#MyGrid').data("kendoGrid");

var choosenItems = gridChoosenValues.items();

for (var i = 0; i < choosenItems.length; i++) //delete every row

{

grid.removeRow(choosenItems[i]); //this triggers delete confirmation :(

}

hope this will be fixed soon. And a method for deleting all rows of a grid would also be very nice :)

Best regards,
Mathias
