Can't get kendo grid to work in MVC without MVC wrapper

I'm building a 'sample' project in asp.net MVC for my clients to show them how to interface with our services, and i'm using kendo core which means no MVC wrappers. Basically i have the javascript:

function loadAttGrid() {

var attgeturl = "@Url.Action("_GetAttachmentListJSON", "Attachment", new { area = "MVCPlug", id = ViewContext.RouteData.Values["id"] }, null)";

var attupdateurl = "@Url.Action("_UpdateAttachment", "Attachment", new { area = "MVCPlug", id = ViewContext.RouteData.Values["id"] }, null)";

var attdeleteurl = "@Url.Action("_DeleteLogEntry", "Attachment", new { area = "MVCPlug", id = ViewContext.RouteData.Values["id"] }, null)";

$("#attgrid").kendoGrid({

dataSource: {

transport: {

read: {

url: attgeturl,

type: "GET",

dataType:"json"

},

update: {

url: attupdateurl,

type: "POST",

dataType: "json"

},

destroy: {

url: attdeleteurl,

type: "POST",

dataType: "json"

}

},

parameterMap: function (options, operation) {

if (operation !== "read" && options.models) {

return { models: kendo.stringify(options.models) };

}

},

pageSize: 10,

schema: {

model: {

id: "LogEntryGUID",

fields: {

LogEntryGUID: { editable: false },

FileName: { editable: false },

FriendlyUserName: { editable: false },

LocationString: { editable: false },

EventDescription: { editable: true },

FormattedDateCreated: { type: "date", editable: false }

}

},

selectable: false,

sortable: true,

filterable: true,

editable: "inline",

pageable: {

refresh: false,

pageSizes: false,

buttonCount: 5

},

columns: [

{ field: 'FileName', title: 'File Name' },

{ field: 'FriendlyUserName', title: 'User' },

{ field: 'EventDescription', title: 'Description' },

{ field: 'FormattedDateCreated', title: 'Date Created', format: "{0:G}" },

{

command: [

//define the commands here

{ name: "edit", text: " " },

{ name: "destroy", text: " " }

],

title: " ", width: "85px"

}

]

});

}

which works fine when using MVC wrappers, and the 'read' url for the controller looks like

public ActionResult _GetAttachmentListJSON([DataSourceRequest] DataSourceRequest, Guid id)

{

Models.ArrayOfFullLogEntry theAtts = null;

if (id != Guid.Empty)

{

theAtts = GetAttList(id);

}

return Json(theAtts.ToDataSourceResult(request), JsonRequestBehavior.AllowGet);

}

but it does NOT work if i change the controller to not use the wrapper, like:

public ActionResult _GetAttachmentListJSON(Guid id)

{

Models.ArrayOfFullLogEntry theAtts = null;

if (id != Guid.Empty)

{

theAtts = GetAttList(id);

}

return Json(theAtts, JsonRequestBehavior.AllowGet);

}

what do i need to change in the javascript to make this wrapper-less controller work?

Zooming X Axis Stock Chart

I have an odd problem on the zooming on Stock Chart, the X Axis becomes corrupt.

When I zoom it sorts itself out.

If just plot the points with a default Layout it is OK unzoomed.

I am doing this for both types:

var xAxis = chart.PlotArea.XAxis;

xAxis.Step = Convert.ToDecimal(xAxis.Items.Count * 0.10);
xAxis.BaseUnitStep = Convert.ToInt32(xAxis.Step);
xAxis.BaseUnit = DateTimeBaseUnit.Minutes;
xAxis.EnableBaseUnitStepAuto = false;

Please see attached images.

RadFileExplorer very slow

Hello,

This new FileExplorer control is very, very, very slow to open folders with a lot of files in Internet Explorer 7. Testing with a folder with 1000 jpg files, 4Kb each file, take more than 5 minutes to open in a machine with Dual Xeon processor and SAS 15K speed disk and causes iexplorer process to consume much cpu.

With Firefox works very fast.

Regards,
