Good morning,
i am using MVC.ASP net in my project and i'm trying to send the DataSourceRequest to a service , via rabbitmq.

the message should contains all the request filters set in the ui in order to create an excel report. i have tried to use the System.Text.Json serialization but it's not working properly. it serializes only the first level props.
i have found a ".ToJson" extension  but it's returning a Dictionary<string, object>, not usefule here.

can you suggest how to serialize the DataSourceRequest in Json format? with all nested and recursive properties?

the filters can be about dates, strings, combobox, and so on

thanks in advance

Is there a way to determine what kind of kind of control you have using JavaScript.  For example , if you have a form with several different kendo controls

.data("kendoNumericTextBox")

.data("kendoComboBox")

.data("kendoButton")

I only have the name and id of the control. Is there a way to determine what kind of kendo control that is represented.

I have tried looking through the  jquery selection but I do not see any thing that indicates whether the selection is a kendoNumericTextBox, kendoComboBox etc...

My page has a combo box. As the user selects an ID from the dropdown list, the page populates with information corresponding to the entry. It is an AJAX bound combo box. I am trying to make the combo box get auto populated with an ID from my query string on initialization. 

I've tried setting the .Value field of the combo box. This works to automatically select the correct ID and populate the rest of the page, but only when the ID exists in the data source. My AJAX call returns data based on the partial/full ID passed in, and a list of a few most recent ID's if no input ID is specified. 

I believe this will work if the ID exists in the data source prior to setting the value field of the combo box. But for that to happen, the combo box must use the ID from the url to fetch the data source, similar to what happens when a user manually types that ID into the combo box. However, I am struggling to figure out how to pass in a specific ID when the combo box is responsible for making the AJAX call. 

I would appreciate any advice or other suggestions to getting the intended behavior.

Hello,

Is it possible to prevent the automatic selection event when navigating in a combobox using the arrows keys, just like in the multiselect example  here: https://demos.telerik.com/aspnet-mvc/multiselect/events ???

We are currently trying to upgrade from 2019.3.917 to 2023.1.117

Some code that worked fine in the old version is failing in the new with error in kendo.combobox.js line 1221

Error message
Uncaught TypeError: Cannot read properties of undefined (reading 'renderButton')

Line 1221

values: kendo.cssProperties.roundedValues.concat([['full', 'full']])

the debugger is highlighting the second 'full'.

Our code is quite complex but commenting most of it out I get the same thing so a simplified version:

Our html page has this input

<input id="departments" style="width: 500px;" />

Then our javascript to create the combobox is

var $combo = $("#departments);

objKendoCB = $combo.kendoComboBox();

The second line results in the error. (the actual code sets lots of properties but I removed them one by one to end up with an empty method call).

Any ideas welcome!

In Main View

==========

columns.Bound(p => p.HuomName).Width(50).ClientTemplate("#=HuomName#").Title("H.UOM").Filterable(false).EditorTemplateName("HuomTemplate");

In Editor Template View

=====================

Here's the definition of the two items that are linked by the CascadeFrom:
                      items.Add().Field(f => f.Country)
                                 .ColSpan(1)
                                 .Name("cmbCountry")
                                 .Editor(e => e.ComboBox()
                                               .AutoWidth(false)
                                               .DataTextField("name")
                                               .DataValueField("id")
                                               .BindTo(@CountryModel.Countries)
                                               .Placeholder("--- Select or Type Country"));
                      items.Add().Field(f => f.StateProvince)
                                 .ColSpan(1)
                                 .Name("cmbStatesProvinces")
                                 .Editor(e => e.ComboBox()
                                               .AutoWidth(false)
                                               .AutoBind(false)
                                               .Placeholder("--- Select State/Province ---")
                                               .DataTextField("name")
                                               .DataValueField("id")
                                               .DataSource(dS => dS.Read(read => read.Action("GetStateList", "Address").Data("filterState")).ServerFiltering(true))
                                               .CascadeFrom("cmbCountry")
                                               @*.BindTo(@StatesProvinces.StateProvince)*@
                                               );

Here's the AddressController.GetStateList:

This works for the first Country that is selected...  afterwards - if the Country is changed, the GetStateList is not called again to refresh the related/CascadeFrom Combobox.
