In Editor for imageBrowser and fileBrowser need progressBar.

If upload big file or slow connection user upload file and nothing see

I'm following the example here: https://demos.telerik.com/aspnet-mvc/grid/server-export

But I'm getting a null pointer if any of the grid values are null. Shouldn't it act like the client export and just put in an empty value?

Is there some workaround for this?

Hello,

 

I have a problem with export to excel when treelist contains columns in group

See Dojo 1

1. Last name is second column in browser, however in excel it is last one.

The problem is not so big if data corresponded to header, but header and data do not match!!

2. Group is not a merged column 

 

In certain scenarios we get completely broken file. Dojo 2.

Excel offers to restore file, but after restore, header is even more broken than in first scenario (see attachments)

 

I tested it in chrome with jszip 2.4.0, 3.1.5, 3.2.0

 

Any possibilities to fix it?

 

Hi,

I have a Jquery grid that has a column with dropdown values as below.   All the CRUD functions work 100% and data displays correctly.

The problem is that the filter for the dropdown list shows the object  "[object] [Object]" and not the drop down values from the grid.

I thought I could just use the Filter Menu customization example below... but this doesn't work and doesn't seem to trigger the javascript at all.

Hi,

I know there is plenty of question about formatting Date in DatePicker but I just can`t get it to work.

I have this:

View(razor)
<script src="~/Scripts/kendo/2014.1.415/cultures/kendo.culture.hr-HR.min.js"></script>

<script type="text/javascript">
   kendo.culture("hr-HR");
<script type="text/javascript">

<div id="form-container">
@Html.Kendo().DatePickerFor(m => ugrozenostSvojte.DatumProcjene).Events(ev => ev.Change("onPickerChange")).Culture("hr-HR").HtmlAttributes(new { data_bind = "value: selectedUzrok.DatumProcjene" })

<button id="save">Save</button>
</div>
<script type="text/javascript">
 $(document).ready(function () {
...

kendo.bind($("#form-container"), viewModel);

viewModel.productsSource.read();

$("button").click(function (e) {
            var validator = $("#form-container").kendoValidator();
         if (validator.validate() == true) {
                viewModel.productsSource.sync();
            }
});

});
<script type="text/javascript">

webconfig
 <globalization uiCulture="hr-HR" culture="hr-HR" enableClientBasedCulture="true" />
 
 This part about binding, selecting value from datepicker works fine. But in the value o datepicker is always something like:
 "Wed May 07 2014 00:00:00 GMT+0200 (Central European Daylight Time)".
 
 This same value have been sent to server. Of course, my model in the backend is datetime and is null.

 And if I put some format on datepicker (like .Format("{0:dd.MM.yyyy}")) the I am getting validation message: "The field DatumProcjene must be a date."
 
controller - model.DatumProcjene is null

  public ActionResult UpdateUgrozenostiSvojte(customDataSourceRequest request, UgrozenostSvojteViewModel model)
        {
            var ugrozenostSvojte = this.UgrozenostSvojteService.Update(model);

            return Json(ugrozenostSvojte, JsonRequestBehavior.AllowGet);
        }


model
 public class UgrozenostSvojteViewModel
    {
public DateTime DatumProcjene { get; set; }
}

Please help.

I have a Kendo UI Grid in Angular that includes several foreign keys.  For the most part, the columns' displays can be handled using the 'values' property for the column.  However, I have a column in which I want to display both text and a font awesome image based on the foreign key ID.  I assume this will need a template, but do not know what to enter in the template.  For this column, I want something similar to the following:

Obviously, dataItem.typeId is not what I need to use to get to the image and text, but I do not know what to put here.  For a different column, I created a component and passed in the entire dataItem, but that seems overkill for this.  

Is there a simpler way to reach two fields of the parent table when using a foreign key?

Thanks!

Does the Kendo Spreadsheet have the functionality to have a drop down list in a row like Excel?

I have used hasChanges() to detect dirty flag in dataSource. But it behaves in strange way when we have 1 row inside Grid and if i we delete that still hasChanges() return false. 
              I have created DOJO demo https://dojo.telerik.com/alOHiyOV  
      What is official solution

Hello,

I would like to be able to filter my chart according to dates. The problem is that the filter does not apply correctly. If I put the beach from May 1st to the end of May, I have dates of April and even February 2018 coming up. 

Here is an example Dojo (Normally I receive the datasource dynamically)

Thank you for your help.
