Wrappers in ASP.Net MVC vs html/javascript

Is it possible to do everything using the Grid and Datasource wrappers that can be done in javascript/html? I made the decision, perhaps unwisely, to use the MVC Wrappers for ASP.Net MVC development. But it is far from obvious what the mapping is from JS to the wrapper and if it is complete.

The examples don't help much. I am trying to put together a grid where some columns are foreign keys on another record. For example, Instead of displaying "Mr.", or "Mrs." or "Ms." etc I would prefer to use key values and then retrieve the value from another table. That is simple. But I want to edit inline and I want that field to be a dropdown list of valid titles.I see an example using javascript but I can't see how to replicate that code in a Wrapper. Also, the example uses local data instead of accessing a database but I can figure out how to get the date from a database.

I don't want to continue trying to get the Wrapper to work if the wrapper only supports a subset of the native functionality.The particular area I am having trouble with is in the definition of Fields.

Localization

Hi there

I understand localization is now available for Kendo Ui Complete for ASP.NET MVC.
I know where to find the DLLs for the resources, but how do I implement them? I'm using Razor.

*UPDATE*
The resource DLLs are located in the "bin\language" folder and my globalization settings are set to "Auto". I can make use of my own resources and everything translates automatically. However, the Kendo Grid (like update/edit/cancel) does not change.
What am I missing here?

Kind regards,

Jesse

Kendo MVC with MVC3

Hi,

Can I use the Kendo MVC framework with a MVC3/razor project on visual studio 2010 Sp1? Also what database needs to be on SQL Server to make the localhost Kendo demos work. It keeps failing out trying to connect. Is it looking for an advetureworks database? where can I get one?

I'm presently avoiding upgrading to Visual Studio 2012 cause I don't like the look of it and MS are still deciding if they;re going to skin all the icons.

thanks

Events not firing properly

I'm simply trying to fire an event, and it doesn't work. (I'm starting to feel like Kendo is a beta that we pay to test.)

Markup:

@(Html.Kendo().AutoCompleteFor(m => m.EditName)

.Events(e => e.Select("alert('test')"))

.DataSource(source =>

source.Read(read => read.Action("GetUsers", "Administration"))

.ServerFiltering(true)))

Here's what happens. It fires the alert box upon page load, and never again. Also, it doesn't matter what the event is. I can make the event "Select", "Change", "Open", "Close".... it always fires once upon page load, and never again.

I tried using the Latest Internal build... did not fix it. I just want to fire an event upon Select, not upon page load. Please advise what I'm doing wrong. Thanks.

Changing color of text in currency text box

Hey, I know there has to be a simple way to do this but haven't found it yet.

We have a currency text box that is disabled. When the value in it is less than zero we would like for the text to be red.

I have found ways to change the text color but not on a disabled one. May be best to change background color but still has to be done on disabled object.

Is there a way to do this and if so how?

Any help is appreciated.

Cascading Dropdown posts for results twice when filter returns no results

In this case, I've got a 'vendor' dropdown that cascades off of a 'companies' dropdown. Within the datasource, it is possible for the vendor query to return no results for a selected company.

If I select a company that is associated with vendors, the vendor dropdown gets populated with the applicable values. If I then click on the vendor dropdown i can select values. This behavior is perfect.

If I select a company that has no vendors, I would expect the vendors dropdown to have no choices (or a default choice). However in this case, the vendor dropdown request it's data (/Vendors/Get?companyCode=33), gets no records and then posts a second time to the endpoint. Also the vendor dropdown remains stale, containing any items from a previous cascade operation. Furthermore, if I click on the Vendors dropdown, it initializes two more requests to the data (causing the spinning indicator to appear twice quickly) and stops.

Has anyone run into this double posting on no records issue? See source code below.

<input id="CompanyCode"

data-textfield="ItemText"

data-valuefield="ItemValue"

data-endpoint="http://localhost:8888/Customers/Get"

data-selected="40"/>

<input id="VendorId"

data-textfield="ItemText"

data-valuefield="ItemValue"

data-endpoint="http://localhost:8888/Vendors/Get"

data-cascade="CompanyCode"/>

<script src="Content/js/jquery.min.js"></script>

<script src="Content/js/kendo.all.min.js"></script>

<script>

$(function(){

$('#CompanyCode').each(function(){

var target = $(this);

var options = {

dataTextField: target.data('textfield'),

dataValueField: target.data('valuefield'),

dataSource: {

transport: {

read: target.data('endpoint')

}

target.kendoDropDownList(options);

});

$('#VendorId').each(function(){

var target = $(this);

target.kendoDropDownList( {

dataTextField: target.data('textfield'),

dataValueField: target.data('valuefield'),

dataSource: {

transport: {

read: target.data('endpoint'),

parameterMap: function(options, operation) {

return {

companyCode: options.filter.filters[0].value

}

},

serverFiltering: true

},

cascadeFrom: target.data('cascade'),

autoBind: false

});

</script>

Grid Custom Command and Hash (#) in Url for Single-Page-Applications

I have a single-page-application that uses url hashes to set state for the UI. When generating a grid custom command, the button link is generated as <a href="#"></a>. This causes the hash monitor (jquery-bbq) to load an unintended statefor the UI.

Is it possible to either a) remove the hash from the link or b) set the link to the current hash?

i.e. <a href="#nav=admin&sub=1"></a> where 'nav=admin&sub=1' is already set for the current page state url hash.

TIA

Redirect to another page after update in Kendo grid with inline edit

I have a Kendo grid with inline editing. It works great. An issue I have right now is that after an inline update of a record, if certain conditions of the update exist I need to redirect to another Page i.e. RedirectToAction. So the code looks like:

public ActionResult EditingInline_Update([DataSourceRequest] DataSourceRequest request, OrderViewModel order)

{

if (order != null && ModelState.IsValid)

{

order = UpdateOrder(order);

repository.UpdateOrder(order);

}

if (order.orderStatus == "HD")

return RedirectToAction("Info");

return Json(ModelState.ToDataSourceResult());

}

This code works as designed but will not display the page. This of course is due to the AJAX call which is returning to the datasource.

Several things happen on the line order = UpdateOrder(order); This method is in the Controller and sets several fields in the record that was updated including the orderStatus. The repository.UpdateOrder(order) happens in the SessionOrderRepository class.

Since the fields in the UpdateOrder method of the Controller are not set by the user, the information is not updated in the grid either (grid updates immediately). And if for some reason the orderStatus is placed in the "HD" (hold) state we want to redirect the user to a page that displays the reason(s) that the order is on hold. Clicking Ok on that page would redirect them to the grid and all of the fields would be updated since it has to reload.

Technically this is probably not a Kendo issue but if anyone has a work around on this your help would be greatly appreciated.

Regards,

Paul

MVC Grid command runs javascript function with parameters - is it possible?

Hello!
First of all I'd like to congratulate you on your work.
One small suggestion is that it would be better if you expanded your documentation and examples, especially for mvc.

My question is stated in the title. I have a vs project and I use mvc. I also have some javascript functions that I'd like to fire whenever someone clicks on a button. I can make this happen but I don't know how to pass arguments.

The way I've implemented is by using htmlattributes on custom command and passing new {onclick = "MyFunction()"}.
This works but I need parameters as well. And I need a parameter from the same row's element.

Can you please help me?
Thank you very much in advance!
