Hi:
I am new to using Kendo UI. I am using MVC4  (VS 2012) with Kendo Mvc wrappers. I am trying to display a DropdownlistboxFor associated with a model item. Then during listbox change event i want to save that model (in the controller). I have hardcoded listbox items added to the listbox like in the code below. Should i post an ajax call which will call a controller method that saves model? How do i do this ajax post with model data sent to the controller action with the combo box updated data?

Is there any other way?
Thank you so much for your help.

=========================================
My model code is:
public class PackageModelView
    {
        public int DefaultReason { get; set; }
}
=========================================
View code (say named file Package.cshtml) has:
@using .<model namespace directory>
@model PackageModelView

@(Html.Kendo().DropDownListFor(model => model.DefaultAction)
                        .DataTextField("Text")
                        .DataValueField("Value")
                        .BindTo(new List<SelectListItem>()
                        {
                            new SelectListItem()
                            {
                                Text = "Active",
                                Value = "1"
                            },
                            new SelectListItem()
                            {
                                Text = "In-active",
                                Value = "2"
                            }
                        })
                       .Value("1")
                    )

My old code:
      

Was working just fine
however, since updating to: Kendo 2014.2.1008
This code works sporadically and although the Checkboxes get checked visually this code throws an error and the grid line is not recognized as checked/selected??

how Do I modify the code to fix?
or do I just revert back to old Kendo scripts? 

Hi experts,

First of all, sorry for asking some basic stuff about the grid as I'm quite new on the kendo grid.

As mentioned in the title, I would like to know how do I generate the link that expands the child grid from ClientRowTemplate.

What I'm doing now is altering the hierarchy.cshtml from the demo.  But not getting any luck to achieve this.

Many Thanks,

Victor

Hi,

with this view

 

 

The first clientTemplate works and

#: Title # get bound to Review.Title.

The second clientTemplate does not work, a js error comes , it says can not bind to TableNo. Writing Title instead of Table No will however display the title from Review class. so eventhourgh my grid is bound to ReviewCategory class the clienttemplate is displaying value from Review class.

Is this a bug ?.

Best

Ole

I am using MVC Tabstrip . It seems to put a red-color outline for that tab page, every time we select a tab item. I want to change this color as shown in this page (probably sort of greyish blue). How do i do that?

There appears to be a problem using the Kendo ComboBox and DropDownList along with the client-side MVC unobtrusive validation. The validation errors do not appear on the client. Take the following Razor view for example:


The non-Kendo UI drop down appropriately shows the validation error when the form is submitted, but the Kendo controls do not. The model is very simple and uses attributes for validation:


Please let me know if there is a way to enable the client-side validation for these controls without having to manually wire it up. A solution which reproduces the issue is attached.

     I am trying to change a text of a tab item when a tab item is selected. How do i do that?

For example, disabling another tab-item when a tab is selected is NOT working with the current code.

==============================================================
event handler code (NOT working as far as disabling the tab item):

<script>
   function tabMain_select(e) {
        // gives valid item here - i checked in the debugger.
        var tabstripD = $("#tabMain").kendoTabStrip().data();      
        $(tabstripD).disable(0);
</script>

===========================================================
Code that renders the tab with three tab items (this works):
@(Html.Kendo()
    .TabStrip()
    .Name("tabMain")
    .Animation(false)
    .Events(e=>e.Select("tabMain_select"))
    .Items(tabs => 
                {
                    tabs.Add().Text("Recent History")
                              .Selected(true)                               // Will render as this tab selected
                              .LoadContentFrom("About","home");             // to render a view into this tab. 
                      
                    tabs.Add()
                        .Text("Package")
                        .LoadContentFrom("About","home")
                        .HtmlAttributes(new { style = "margin-right:60px" }); // To give space after this tab but before the next tab item.

                    tabs.Add()
                        .Text("Dirty Returns")
                        .LoadContentFrom("About", "home");
                }
            )
  )
=========================================================

after upgrading to latest version of kendo asp.net mvc 2014.2.903, it is making javascript error "Invalid Template".
It is observed that error occurs if hierarchical grid is filterable, for testing here is the sample code take from the example, i have changed this code to make sub grid as Filterable


@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.EmployeeViewModel>()
        .Name("grid")
        .Columns(columns =>
        {
            columns.Bound(e => e.FirstName).Width(110);
            columns.Bound(e => e.LastName).Width(110);
            columns.Bound(e => e.Country).Width(110);
            columns.Bound(e => e.City).Width(110);
            columns.Bound(e => e.Title);
           
        })               
        .Sortable()
        .Pageable()
        .Scrollable()
        .ClientDetailTemplateId("template")
        .HtmlAttributes(new { style = "height:430px;" })
        .DataSource(dataSource => dataSource
            .Ajax()
            .PageSize(6)
            .Read(read => read.Action("HierarchyBinding_Employees", "Grid"))            
        )        
        .Events(events => events.DataBound("dataBound"))
)

<script id="template" type="text/kendo-tmpl">
    @(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.OrderViewModel>()
            .Name("grid_#=EmployeeID#")
            .Columns(columns =>
            {
                columns.Bound(o => o.OrderID).Width(70);
                columns.Bound(o => o.ShipCountry).Width(110);
                columns.Bound(o => o.ShipAddress);
                columns.Bound(o => o.ShipName).Width(200);
            })
            .DataSource(dataSource => dataSource
                .Ajax()
                .PageSize(10)
                .Read(read => read.Action("HierarchyBinding_Orders", "Grid", new { employeeID = "#=EmployeeID#" }))
            )
            .Pageable()
            .Sortable()
            .Filterable()
            .ToClientTemplate()
    )
</script>
<script>
    function dataBound() {
        this.expandRow(this.tbody.find("tr.k-master-row").first());
    }
</script>

I have a grid with 2 child grids defined as client templates. I want to handle server side validation as described here: http://blogs.telerik.com/kendoui/posts/13-08-29/handling-server-side-validation-errors-in-your-kendo-ui-grid but I am unsure of how to have the javascript for each client grid as each grid has a different ID and will need a different errors list.
