I am using MultiColumnComboBox in my application which binds to the datasource correctly but when I click the dropdown button, the list does not render properly. All the data shows in one column. The column headings render properly though.

I have 2018.3.1017.545 version of Kendo.mvc.dll. Below image shows how the data is render in the drop down.

Hi

I have issue with Kendo treeview expanding in my MVC project. I try to expand treeview node (which have children nodes) at same time when I select it. The code went through in .js file without error.  but node didn't expand. Could any one tell me what properly be wrong? below are piece of code.  Thanks.

        var selectedNode = $("#treeView").data('kendoTreeView').dataItem(e.node); // selectedNode have correct data after this.
        var treeView = $("#treeView").data('kendoTreeView');
        treeView .expand(selectedNode); //Code went through without error

Currently evaluating the Upload control, I ideally want only a simple upload button to select local files and do everyting else on my own through the client API.

Especially the gray div (k-widget k-upload k-header) around the button bothers me.

My question:

Is it possible to tell the Upload control to simply display the core upload button and omit everything else, even after the user has selected files?

Is there a way to get the responsive behavior for the menu to change to a hamburger menu when the screen size is small? I saw this older post and was wonder if anything has changed.

The behavior would be similar to http://getbootstrap.com/examples/navbar/

Thanks

I've a grid with ajax binding and exports to excel/PDF fine when dealing with less than a thousand records. But when I want to export bigger quantities the grid doesn't do anything at all. I even put breakpoints in both export actions with no luck.

What can I do to solve this issue?

This is my grid:

<script src="~/Scripts/lib/pako.js" type="text/javascript"></script>

Thank you very much

When working with the .Group property, there is an option for changing the sort.

.Group(group => group.Add(p => p.fieldname))

it would appear that you should be able to set the System.ComponentModel.ListSortDirection

This is not working, and the documentation is abysmal.

Instead of the group sorting asc, I need it to sort desc.

In my view page, I'm using Kendo.MVC.UI and Html Helpers. But it does not show me the MultiColumnCombBox. This command below gives me an error saying MultiComboBox method is not found.These are the JS files that I've included in my view.

@(Html.Kendo().MultiColumnComboBox() .Name("customers") .DataTextField("ContactName") .DataValueField("CustomerID")........

Can you let me know what is missing?

Hello. I am trying to implement a dropdownlist and I need some help. I have 2 simple tables (Employee and Department). Each employee belongs to a department and a department can have multiple employees. I am using EF database first approach. EF generated the 2 classes (Employee.cs and Department.cs) and each class has a reference to the other.

This is my controller actionmethod

public ActionResult Kendo()
        {
            db.Configuration.LazyLoadingEnabled = false;
            var departments = db.Departments.ToList();
            ViewData["departments"] = departments;

            var employees = db.Employees.Include(e => e.Department).ToList();
            return View(employees);
        }

The view is

@(Html.Kendo().Grid(Model)
        .Name("Grid")
        .Columns(c =>
        {
            c.Bound(e => e.EmployeeId);
            c.Bound(e => e.FirstName);
            c.Bound(e => e.LastName);
            c.Bound(e => e.Gender);
            c.Bound(e => e.City);
            c.Bound(e => e.Department.DepartmentName);
            //columns.ForeignKey(e => e.DepartmentId, Model.Select(e => e.Department), "DepartmentId", "DepartmentName");
            //columns.Bound(e => e.Department.DepartmentName).EditorTemplateName("DepartmentEditor").Title("Department").Width(250);
            //columns.Command(command => { command.Edit(); command.Destroy(); }).Width(200);
        })
        //.DataSource(d => d
        //    .Ajax()
        //    .ServerOperation(false)
        //)
        .Pageable() //Enable the paging.
        .Sortable() //Enable the sorting.
        .Filterable()
        .Scrollable()
)

The EditorTemplate

@(Html.Kendo().DropDownList()
          .Name("Department")
          .DataValueField("DepartmentId")
          .DataTextField("DepartmentName")
          .BindTo((IEnumerable)ViewData["departments"])
)

Issues I am having:

• I am getting a circular reference if I uncomment the datasource line in the view.
• I need to have CRUD operations and I need to show the department as a dropdownlist on Edit/Add. On Edit, the dropdownlist needs to select the current department of the employee. 

Thanks.

Hi,

I have a grid that has one dynamically sized column to maximize space (it contains the most data).  As the browser window is resized to be smaller and that column shrinks, it eventually disappears.  All of the other columns are auto-sized to contents.

Is there a way to set a minimum width for the column so that when I resize the browser window, it will freeze the width of that column when it reaches a certain threshold and scroll instead?

(I am using the MVC suite of controls.)

Thanks!
Brian

Hello,

I am trying the Kendo Slider for ASP MVC and want to set the inital values programatically. To do this I have this line of code:

But when the site is rendered the selectionStart-value is set to 6 and the selectionEnd-value is set to 55. It seems that the decimal-point ist forgotten.

An additional problem is a linebreak at the end of the renderd slider. For both problems I have added an attachment.

Can you help me to fix the problems? Thank you.

Best regards, Martin
