Hi, in a grid popup edit template I got a field bound like:

@Html.HiddenFor(model => model.LogoUrl)

This field represents an image URL stored in Azure Blob.

I already got a Kendo Upload in the edit template that upload the image to Azure, but in the KendoUpload success return function, I need to set the URL received by azure in the object currently edited. For now I try this:

But the databinding are not hit and the underlying model is not changed. How I can achieve that?

Hi,

I have issue with chart after upgrade kendo libraries to R3 2018 (ver. 2018.3.911.545). Here is my code snippet:

and this is my layout with references:

I also already updated it with telerik.ui.for.aspnetmvc.hotfix.2018.3.911.commercial libraries but still getting the same error. Fyi my project use MVC 5 and bootstrap 4.

Any thoughts on how to fix this greatly appreciated.

Thanks.

We have a Web API where the controller classes implements ApiController. 

The CRUD-operations looks like:

public IHttpActionResult Get()
public IHttpActionResult Get(int id)
public int Post(Company company)
public void Put(Company company)
public void Delete(int id)

Adding a Kendo UI ASP.NET MVC Grid that view data works, but we got stuck binding to datasource when we tried to implement inline-editable rows. 

The API methods on the demo page, https://demos.telerik.com/aspnet-mvc/grid, takes a DataSourceRequest as a parameter. 
Here it gets confusing especially when the documentation is not so comprehensive.

Can't we just use our API as it is, do we need to create yet another class where all the CRUD-operations takes the DataSourceRequest parameter?

if I add:

.Group(g => {
                g.Add(c => c.DistrictName);
                g.Add(c => c.SchoolName);
                })

to my datasource:

.DataSource(ds => ds
            .Ajax()
            .ServerOperation(false)
            .Read(read => read.Action("RetrieveReqStatusReport", "ReportSupport", new { orgId = ViewBag.OrgSelection.Id, personId = ViewBag.PersonId, yearId = ViewBag.YearSelection.Id }))
            .PageSize(50)
            .Group(g => {
                g.Add(c => c.DistrictName);
                g.Add(c => c.SchoolName);
                })
        )

then

 function filterMenuInit(e) {
        if (e.field == "DueDate") return;
        var filterMultiCheck = this.thead.find("[data-field=" + e.field + "]").data("kendoFilterMultiCheck")
        filterMultiCheck.container.empty();
        filterMultiCheck.checkSource.sort({ field: e.field, dir: "asc" });

        filterMultiCheck.checkSource.data(filterMultiCheck.checkSource.view().toJSON());
        filterMultiCheck.createCheckBoxes();
    }

generates the following error when I try to filter:

Uncaught ReferenceError: DistrictName is not defined
    at eval (eval at compile (kendo.all.min.js:25), <anonymous>:3:209)
    at Object.render (kendo.all.min.js:25)
    at Object.d [as render] (jquery.min.js:2)
    at init.createCheckBoxes (kendo.all.min.js:45)
    at init.filterMenuInit (1:371)
    at init.trigger (kendo.all.min.js:25)
    at init.c (kendo.all.min.js:53)
    at init.trigger (kendo.all.min.js:25)
    at init._init (kendo.all.min.js:45)
    at init._click (kendo.all.min.js:45)

if I remove it, multi-filter works fine.

TIA for the insight into what I'm failing to understand.

Hi,

I need to filter a combobox based on the value of a check box.
I explain.

I have a checkbox that will start unchecked (value 0).
And below is a combobox that will use an api to fetch the data.
If the user selects this checkbox, the data from the combobox must be updated.

Very similar to this example: https://demos.telerik.com/aspnet-core/combobox/cascadingcombobox
But using the checkbox.

Can someone help me?
I am using ASP.NET MVC Core.

I have an old application where the user was entering an input a dropdown list (of multiple values concatenated) was displayed and he could filter the list based on the values displayed.

Now we decided to use Combobox since the Autocomplete does not open the dropdown when the autocomplete receives focus. Since the list contains too many values I though I should try also virtualization

However when I write something in the combobox no event is triggered on the server. If I open the dropdown manually the server is called.

I tried removing the Virtual and the result was the same (Probably it did not worked because I left the Ajax and the PageSize).

Hello all. i'm a newbie for use kendo mvc.

I'll want to know how to programmatically for scheduler mvc ajax on client side .

when i'm single click on date it auto create task and then redirect to another controller.

sorry for my bad english.

thank you very much.

I'm using a Kendo Date Picker (2018.1.221.545) on a page like this:

The model for ClinicBeginDate looks like this:

Note that DateRangeYearAgoToToday is a custom validation attribute.

If I enter a future date and click Save the server side validation works correctly, the form is re-displayed and an error message appears next to the date field. But when I change the invalid date to a valid one (within the past year) and click Save, the form is re-displayed, the date field is blank, and the error message 'Date Clinic Began is required' appears.

After debugging with developer tools I discovered that when Save is clicked the first time with the invalid date, the field is included with the posted form data. The second time Save is clicked it is not. As a result ClinicBeganDate is null the second time and a required validation error results. This happens even though a date is clearly displayed in the field before Save is clicked the second time.

So the problem seems to be the server side validation, but I don't understand why that would prevent a date picker field from getting posted in the form data. Any ideas how to fix this? Obviously I can do the date range validation on the client side but that just hides the problem.

Thanks...

Hi, I have a grid with two frozen columns and numerous columns representing the months of the year starting from the previous year, and extending 5 years into the future.  What I would like to do, is on DataBound, have the column for January of this year be the first column the user sees (in the horizontal scrollable section).  I'm looking for some way to scroll the grid programmatically to a specific column.  Is that possible?  If so how?

Thanks,

Mike
