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!

Hi,

 

I wanted to try and install the 2018 release trial of Telerik for Asp.net Core from nuget, however the only version that is listed is

Telerik.UI.for.AspNet.Core.Trial 2017.3.1026

Is it missing from the private nuget feed ?

 

I used https://nuget.telerik.com/nuget as my nuget feed.

 

Thank you

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)?

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

Using ASP.NET Core 2.0 Razor Pages

Currently I have a cshtml page that renders a combo/dropdown

 

<select asp-for="DoctorPractice.DoctorId" class="form-control" asp-items="ViewBag.Doctors"></select>

the PageModel for the view contains some code to populate the ViewBag

 var doctors = _context.Doctors;
ViewData["DoctorId"] = new SelectList(doctors, "Id", "FullName");

 

This all works fine - however, now I wish to use the Telerik AutoComplete control because of it's nice features.

I tried this code below without success - i just get js errors.

 @(Html.Kendo().AutoComplete()
                  .Name("doctors")
                  .Filter("startswith")
                  .Placeholder("Select doctor...")
                  .BindTo(ViewBag.Doctors)
             )

Please can I have an example for Razor Pages using the AutoComplete control?

Thanks,
