Kendo helpers partially broken in Asp.net MVC

This is a very weird behaviour but for some reason we can initialize Grids using Kendo's MVC HTML style helpers but DropDownList, DropDownListFor and other widgets just don't work.

Here's the code:

@(Html.Kendo().DropDownListFor(model => model.Gender) .OptionLabel("Select Gender").BindTo(Model.GenderList).Deferred(true))

@Html.ValidationMessageFor(m => m.Gender)

There are no JS errors but the resulting HTML looks like this:

<input type="text" value="-1" name="Gender" id="Gender" data-val-required="The Gender field is required." data-val-range-min="0" data-val-range-max="1" data-val-range="Gender is required" data-val="true" class="input-validation-error">

<span data-valmsg-replace="true" data-valmsg-for="Gender" class="field-validation-error"><span for="Gender" class="">Gender is required</span></span>

If I instantiate this via javascript using a normal MVC drop down list:

<h3>Test Drop Down list</h3>

@Html.DropDownListFor(m => m.Gender, Model.GenderList, new { @class = "dropdown-list form-control"})

<script>

//instantiate drop down lists

$(".dropdown-list").kendoDropDownList();

</script>

It works!

So I assume the Kendo libs are loading fine, but for some reason the MVC side of things are only partially working.

Grids work:

@(Html.Kendo().Grid<DependantModel>(Model.Dependants)

.Name("Dependants")

.Columns(columns =>

{

              ... left out for brevity

}) .DataSource(dataSource => dataSource

.Server()

.Model(model => model.Id(p => p.Id))

.Destroy(update => update.Action("EditingInline_Destroy", "Grid"))

)

.Deferred(true)

)

Charts work but the code is too long to paste here.

Any ideas why other widgets won't work?

Telerik MVC With Kendo accessing Web API

I have seen some examples of using server side Kendo extensions to access Web API calls in the same project. But what about if the Web API is a different project and URL? We are doing this as an N-Tier where the Web API is the data access for multiple client applications. Do you have a same using the server side KendoGrid to access a Web API call that is located on a different server/URL? I can't figure this out.

Here is what I have tried. Both projects have a reference to the data classes so I hope to send a known type back and forth. But this doesn't work:

@(Html.Kendo().Grid<CustomerOrderModel>()
.Name("Grid")
.Columns(columns =>
{
columns.Bound(o => o.OrderNumber);

columns.Bound(p => p.Description);

columns.Bound(p => p.Description2);

columns.Bound(p => p.Notes);

})
.DataSource(dataSource => dataSource
.WebApi()
.Read(read => read.Url("http://localhost:52559/api/CustomerOrder").Type(HttpVerbs.Get))

)
)

Additonal Parameters with Filterable.UI

I'm currently looking at Filters on the ASP MVC grid.

I have this line on my grid:

.Filterable(filterable => filterable.UI("$.fn.kendogrid().userDropdownFilter"))

which works fine, and I can access the original filter element in the userDropdownFilter(element) function in my JavaScript.

I was wondering if it was possible to send additional parameters to this function though, and still pass the original element variable?

Thanks

How to prevent the default row edit?

Hi,

I'm working on a use case where the user is requires to enter a text before he is allowed to edit the content of a row. I want to use a jQuery UI Dialog to prompt a small form that the use need to fill before the row go to edit mode. Using jQuery I was able to bind a handler to the "click" event of the edit button, so I can open the dialog. However I can't find a way to prevent the grid from switch into edit mode before I get the response from the dialog.The result is that if the user close the dialog he can edit the row without fill out the form. Any ideas on how to prevent the default row edit?

Frozen (Locked) Column Rows Not Aligned with Unlocked Rows

I'm utilizing the new frozen (locked) column functionality in the latest release (2014.1.318.340) and noticed that the rows of the locked columns do not line up with those of the unlocked columns (see attached screenshot). If I click around it eventually realigns itself, but this isn't acceptable for our client. I believe in one of the non-MVC forums you provided a fix for this issue. Thanks!

Adding Datapicker, Dropdown and other controls to Kendo Grid

Hi,

We have an requirement that allow a user to enter multiple records at a same time. As I have seen the demo, I feel the batch editing is good option for us.

But we might have a issue that, we need to allow user to select a data from different controls such as Dropdown list, Datepicker and may be some other. In one of the demo sample, I have seen that Dropdown list is added to a column by specifying Foreign Key column mapping (If I am not wrong, that has been done by using Entity Framework).

We are using Model class as source to bind the Grid and we are not using Entity Framework here. By binding Model class is it possible that, we can add these different controls to the columns and is there any examples or sample code?

Regards!

Grid inCell editing: disabling conditional

Hello, I have this grid:

@(Html.Kendo().Grid(Model.ListiniRighe)

.Name("ListiniRighe")

.Columns(columns =>

{

columns.ForeignKey(l => l.LForId, listFor, "LForId", "Formula");

columns.Bound(l => l.DocAmount).Format("{0:c}");

})

.ToolBar(toolbar => toolbar.Create())

.Editable(ed => ed.Mode(GridEditMode.InCell))

I want to disable the "DocAmount" cell if the "LForId" have a specific value, and everytime I change the value I want to check and enable\disable the cell.
How can I do that...
