ServerSorting and ServerFiltering on child attributes or custom properties

I have a blocking issue on my serverside filtering and sorting of data.
My Kendo Grid sends requests to my C# backend.
This is what happens:

I fetch all Employee objects (I use Data Access)
An employee has a Person object, which contains person info like FirstName, LastName etc.
And it also has a GroupName
So my scheme is:

schema: {

model: {

id: "ID",

fields: {

FirstName: { type: "string", from: "Person.FirstName" },

LastName: { type: "string", from: "Person.LastName" },

GroupName: { type: "string" },

}

},

When I use a filter or sorting on the firstname or lastname, it wil try to filter the employee on attribute "Person.FirstName".
But the person is an addition to my DataAccess object, so it is not in the database.

When I use a filter or sorting on GroupName, it will also try to just filter on the groupname. But the groupname is filled in the backend and comes from EmployeeGroup.Name

So I am not able to filter serverside on any of these rows.
I would really love to know if there is any possibility to filter on custom attributes or childattributes.

Thanks in advance!

How to force Reload of Combobox in Grid

Dear Telerik Team!
I would really like to know how to make an ajax-bound combobox reload its items with a given filter value. In the attached example I've got a editortemplate for Country1

@(Html.Kendo().ComboBoxFor(m => m)

.DataTextField("DisplayName")

.DataValueField("Code")

.AutoBind(true)

.DataSource(ds => ds

.Read(read => read.Action("CountryLoading", "Home"))

.ServerFiltering(true)

)

When the Combobox gets focus, i want to reload it. I tried all this:

function CommidityFocus(e, upperE, elementName) {

var combobox = $(elementName).find('span').children('input').data('kendoComboBox');

Combobox.value("hurz"); // No Reload ?!

combobox.search("hurz"); // No Reload ?!

combobox.dataSource.read(); // No Reload ?!

}

but ... nothing happens. The CountryLoading function is not called...
How can I make it reload ?

Show Column Menu Only in Certain Columns

In a Grid. How best would I hide the column menu for certain columns? I have a few column headers that align to the right. The arrow appears behind the text and makes it difficult to read the Column Title. I would simply like to hide the Column Menu for these columns.

I am not referring to hiding them from appearing in the Column Menu itself.

In the below screenshot, I want to see the column menu on Company but not on Sum of Qty or Sum of Order.

The use of "Kendo Controls in the content editor

Hello.

I want to insert one of Kendo Controls in the content editor.
For Example, DatePicker
I use the following code:

var editor = $("#editor").data("kendoEditor");
var elementHtml = "<input id='dtp' />";
editor.exec("inserthtml", { value: elementHtml });

Then executes the code for the DatePicker:

var dtp = $(editor.body).find("[id='dtp']");
dtp.kendoDatePicker({ animation: false });

But only displays the input field itself DatePicker is not loaded.

Tell me, what is wrong.

Thanks in advance.
Regards,
Alexey.

P.S. If I use the insert simple elements (like a button or a text box), everything is displayed correctly.

Editor does not allow you to use the JQuery function "find".

Hello.

Now use the insert controls in the content editor.
I need to search for items on the "class" attribute using jquery function "find()".
As a container for search uses the <div> editor.
However, the function "find()" returns an empty set of elements, although the elements are within the editor.
Tell me how you can solve the problem?

Thank you.
Regards,
Alexey.

Syncronize Url Hash with Grid Sorting & Filtering Selections

Hi,

Is there a method of the Grid (MVC or html) that would generate a url hash representing the current sorting & filtering selections?

Something like '#gridoptions=(sort:column1.desc,column3.desc+filter=state:CA)"

Likewise is there a method that can consume this string back again so that the next async load represents the selections in the hash string?

A demo with Angular or Sammy would be great too, if one exists.

It would be useful to have this in order to
* preserve sorting & filtering on page refreshes
* allow users to book mark a page with a specific sort & filter
* persist this information in a store for retrieval later for metrics or user history features

Thanks!
