Reverse direction of linear gauge (vertical), moving from top to bottom

As the title reads, is it possible to reverse the direction of a vertical linear gauge, so it starts to move from top to bottom? My scenario is the following:
I'm feeding the gauge with real time depth data, and I have defined top / surface to be at 0. When moving deeper, I'd like the pointer to move downwards towards the bottom of the gauge.

It moves fine with the real time data now, but in the wrong direction :)

Any suggestions?

<script>

function createGauges() {

$("#depthBar").kendoLinearGauge({

pointer: {

value: 0,

shape: "arrow"

},

scale: {

majorUnit: 1000,

minorUnit: 500,

min: 0,

max: 12000,

vertical: true,

}

});

}

$(document).ready(function() {

createGauges();

});

</script>

No borders in grid, but on Input

Using this custom CSS I am able to remove all the borders on a gird. Works great.

/* Grids can't have borders */
.k-grid, .k-grid * { border: 0 !important; }

the problem is that it removed borders from all the elements in the grid. How can I edit the CSS so that only the Gird has all the borders and lines removed, but all the child controls still have their borders?

Drag and drop with remote datasource bug.

Im pretty sure i have found a bug with the treeview.

Here is a fiddle that illistrates the problem: http://jsbin.com/ocaraj/3/edit

To see the bug open up a console window and drag a node into a node that you have not loaded, ie. the nodes children have not been loaded. In the 'dragend' event (and possibly others) the e.sourceNode is null if you drop it on an unloaded node. But if the node has been loaded it works as normal, ie e.sourceNode is the dropped node.

Metro theme menu border color has changed in 2013.2.716

The following style was added to the kendo.metro.css on line 1025.

.k-menu.k-header,
.k-menu .k-item {
border-color: #4c5356;
}

This is the only instance of this color in the file. Is this an intentional change?
The previous color was #dadada since .k-menu.k-header was undefined.

Using Html.BeginForm in a Grid Template in MVC

I have the following Razor code in a Template from a Column. The div inside the form renders fine, but strangely the <form> tags from the Html.BeginForm do not get rendered.

(I need a separate form in each of the cells)

columns.Bound(e => e.DisplayText).Title("ACTION").Template(

@<text>

@if (item.UserClient.IsActionAvailable())

{

using (Html.BeginForm("Subscribe", "eServices", FormMethod.Post, new {id = @formId}))

{

<div id="@divId" class="subForm">

<input type="hidden" name="User" value="@clientId" />

</div>

}

Cannot create, update or destroy records in grid with web services

Hello!

I'm starting to work with kendo but I'm having some trouble setting up a grid with inline edit mode and crud operations.

The read method is working and the grid is populated on page load with the two records fetched by the web service getallevents.
However, the other operations fail with the following messages:

Create

{"Message":"Invalid web service call, missing value for parameter: \u0027events\u0027.","StackTrace":" at System.Web.Script.Services.WebServiceMethodData.CallMethod(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters)\r\n at System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

the data I get in browser is:

{"eventid":null,"contextid":null,"eventname":"sd","eventdescription":"sd","eventprice":3}

Update and Destroy

{"Message":"Cannot convert object of type \u0027EventReady.kdEvent\u0027 to type \u0027System.Collections.Generic.IDictionary`2[System.String,System.Object]\u0027","StackTrace":" at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n at System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize(JavaScriptSerializer serializer, String input, Type type, Int32 depthLimit)\r\n at System.Web.Script.Serialization.JavaScriptSerializer.Deserialize[T](String input)\r\n at System.Web.Script.Services.RestHandler.GetRawParamsFromPostRequest(HttpContext context, JavaScriptSerializer serializer)\r\n at System.Web.Script.Services.RestHandler.GetRawParams(WebServiceMethodData methodData, HttpContext context)\r\n at System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)","ExceptionType":"System.InvalidOperationException"}

the data I get in browser is:

{"__type":"EventReady.kdEvent","contextid":56,"eventid":2,"eventname":"Evento Teste","eventdescription":"Testedsds","eventprice":3}

Here is my ascx:

Touch Gesture Support for Kendo UI Web

Hi,

The website I am creating is responsive and displays on mobile, tablets and PCs. I'd like to know if KendoUI web has support for touch gestures such as:

Tap
Hold - e.g. to load a context menu or something similar
swipe left
swipe right
swipe up
swipe down
pinch
rotate-left
rotate-right

At the moment I am looking at Hammer.js - http://eightmedia.github.io/hammer.js/

I would much prefer if Kendo supported these features.

Can you please let me know if :
1. Kendo UI Web does support these gestures?
2. Can I somehow use Kendo UI Mobile and Web at the same time to support these features?
3. Will these features be supported in the future for UI Web?

Thanks
