Please provide an example of Async file upload in Razor using .net Core. The only examples I can find use the HttpPostedFileBase which is replaced in .net core.

http://demos.telerik.com/aspnet-mvc/upload/async

Please post a how to, or direct me to an appropriate existing document guide on how to implement this in .net core. Is this supported yet? If so where can I find the correct documentation with demos and example code?

Thanks

Firefox ESR, date field not initialized as DatePicker

When mapping a date file as grid column, it's not being transformed into a DatePicker.
This doesn't happen with Edge, Chrome or the latest Firefox, I'm only experiencing this with the ESR version of Firefox.

Example:

@(Html.Kendo().Grid<HuntingReportModel>()
.Name("test")
.Columns(x => x.Bound(y => y.Date))
.ToolBar(x => x.Create()))

See attachment for the resulting control...

using jquery ui without the wrappers it works.

manually calling .kendoDatePicker helps but it's really just a bad workaround...

Browser: Firefox ESR (52.5.3 & 52.6.0)

Kendo: 2018.1.117

DateTimes UTC on the server Local time in the browser

Hello!

I'm using the grid to display some LastUpdateDate which is saved as UTC in the database. I want to display this dates to the user in the local browser time zone in "g" general format based in the user settings. ex: "1/26/2018 14:15 PM".

Date in the database: "2018-01-26 17:15:13.130" UTC

Local time in which the data was saved "2018-01-26 14:15:13" my local time

What the grid displays: "1/26/2018 5:15 PM" Wrong!

Thanks in advance!

EditTemplate with DropDownList

Hello,

Isn't it possible to use a Kendo DropDownList in the Grid EditTemplate and pass the Parameter for the Dropdown with the Kendo Template Syntax like this: new {mitgliedid = "#: Mitglied_ID #"}

Here a example:

@(Html.Kendo().DropDownList()

.Name("products")

.DataTextField("ProductName")

.DataValueField("ProductID")

.DataSource(dataSource => { dataSource.Read(read => read.Action("Lookup", "Berechtigung", new {mitgliedid = "#: Mitglied_ID #"}))

.ServerFiltering(true); })

.ToClientTemplate()

)

or is the only way to pass that parameter in the Grid Edit Event (e.model)?

How to raise datasource's error event in Kendo

I have Kendo grid that is configured for batch edit as per the demo. Instead of making 3 separate calls to server for Create, Update and Delete I am handling the SaveChange event of the grid to save all changes ( to maintain transaction)

var grid = $("#grid").getKendoGrid();

grid.bind("saveChanges", function (e) {

var data = grid.dataSource.data();

// collect updated rows and new rows

var items = $.grep(data, function (item) {

return item.dirty || item.id === 0;

})

// collect deleted rows

$.each(grid.dataSource._destroyed, function (index, item) {

item.IsDeleted = true;

items.push(item);

})

$.ajax({

type: "POST",

data: items,

url: "save",

contentType: "application/json; charset=utf-8",

processData: true,

cache: false,

})

.done(function (response, textStatus, jqXHR) {

// do something

})

.fail(function (jqXHR, textStatus, errorThrown) {

// How do i inform datasource or grid about error

})

If there is an error on server while saving changes, the datasource does not know about it. How do i inform datasource ( or trigger error in datasource) that the save operation is failed?

Right now if there is an Error during save, datasource does not know about it and datasource sets updated record's dirty property to false and also clears dataSource._destroyed collection. Beacuase of that if after error user clicks SaveChanges again, the above code will only find records with id zero
