Json security when connecting to grid using .net webapi service

Hi,

We are looking to use the json method to retrieve data from a web/cloud database. But also to allow access from mobile devices.

Is there a proven method to send a secure token in the json header etc. or an alternative method. I have browsed for a solution but i found nothing. We are using the default .net membership/roles and authorize at the moment.

Any help or an example would be great.

Using Mobile with MVC pages that have _Layout.cshtml

I am using MVC4 and displaying mobile views to mobile clients. Each page makes use of the master page (_Layout.Mobile.cshtml) which has the layout definition, references to the mobile CSS, JS and initializes the kendo application.

From the examples I have seen, it appears you are suppose to have the layout definition only once, then, every other page should just have a <div> with a data-role="view". This way, when clicking links the ajax call simply gets the contents of the view and replaces the current view.

Currently, when I try to link between pages, the "loading" flickers non-stop. I believe that problem is that the ajax call to get the page is expecting only the <div data-role="view">, but I'm providing a page with everything on it.

Is there a way to just get the contents of the <div data-role="view">, similar to how jquery's load() takes the URL and an optional selector?

MVVM bound dropdownlist selection bugging out

Check out my jsfiddle example. I don't know what I'm doing wrong but after you click an item in the grid an edit box will apear below. If you change the dropdown value from female to male it works, but after that try switching back to female and it just bugges out and stays on male. I use dropdown lists in this way in a lot of places and i get that issue all the time, it always wont change anymore if you set it to the first value from the datasource.

use k-block for layout ?

hi,
is it good practice to use k-block as layout base? I can not find any documentation of it - just an example here:

http://demos.kendoui.com/web/styling/panels.html

Or is it better to use my own containers?

Thanks,
Matthias

kendo combobox & kendo-knockout dynamic add/remove next available value set

The issue happens when I try to set the next available value in combobox, here is what my scenario is.

I have a list of available items which I display in a combobox, user can select one item & assign at which point I add it to a list/table, user can remove an item from selected at which point it goes back into available list.

Now the issue occurs when the following is done
1) Select & assign couple of items (notice next available item is selected in combobox)
2) Remove an item from the selected list/table (item should now be available to select in combobox)
3) Now try to select the same item & Assign again & notice the next available value in combobox.

Here is a jsFiddle where issue can be reproduced (works only on chrome) http://jsfiddle.net/navnitmehta/fHXBx/7/

I am not sure if this is an issue with kendo or kendo-knockout binding.

Thanks!

value() not correctly updated when deleting text from Combo Text

The issue is that the value() property still contains the previously selected value when the user deletes the text from the Combo input, this is causing issues when we are using it with knockout-kendo binding, basically once a value is selected; there is no way for user to un-select the value.

Here is the jsFIddle to reproduce the issue: http://jsfiddle.net/navnitmehta/vaLyw/

Further analysis specific to knockout-kendo binding can be found here: https://github.com/rniemeyer/knockout-kendo/issues/26

How to upload a single file synchronously along with model

Hi,

I'm using MVC 4, Knockout, and the KendoUI Upload widget.

I have a simple form with several fields plus a single file upload to allow the user to upload one file.

I want it all to go back to the controller in a submit method something like "public ActionResult Submit( Model model, IEnumerable<HttpPostedFileBase> file ). I don't want to use async uploading.

As it turns out, the model is properly populated, but both the "file" parameter and Request.Files are empty.

Could someone provide a full *working* example? I've spent hours scouring this site, StackOverflow, and more without finding such an example.

Thanks!

I am new to the Kendo UI and trying use it in the new VS2012 with JQuery 1.8.0. I used it on new MVC 4 project. I have use the sample from the Grid Basic Usage HTML page and copy it on to one of the project page, added all scripts & CSS files including the people.js data file.
First I use the NuGet to gets the Kendo UI in to the solutions, that seems does not work at all error seems to be Object does not support property or method 'kendoGrid'. Then I delete this project and create a new MVC4 solution, added Kendo UI from downloaded from Telerik Website, note that it is Open Source version. After attached to the solution, linked scripts & CSS files on to the page.
This seems to work but sometimes it pop up the same error as before.

Can't send through parameters, or pick up JSONP format?

I know I'm missing something here, I have to be, although I've had the issue before and never got around it. What I'm doing is:

var ds = new kendo.data.DataSource({
     transport: {
            read: "http://localhost/HOLService/HOLService.svc/GetFiles",
            dataType: "jsonp",
            data: {
                    roleId: function() { return 1; }
               }
            },
           parameterMap: function (data, operation) {
           if (operation != "read") {
                  return { jsonData: kendo.stringify(data.models) };
            }
        }
});

ds.read();

What this does is send a call to "http://localhost/HOLService/HOLService.svc/GetFiles", but there's no roleId parameter, or callback required from JSONP.

Can anyone see what I'm missing here?

Update:
Sorry, ignore this, I didn't have my parameters in the read: {} array.
