[Solved] 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!

Help! New to Kendo UI

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 someone help me, thanks in advance.

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.

Bulk Updating a Checkbox Column (Select All)

I am trying to figure out how to bulk update a checkbox column in a kendo grid. I have a "Select All" toolbar button with the intent of updating a boolean value (from a remote datasource) across all rows of the datasource. This button simply calls a javascript function that looks like this:

var dataSource = $("#grid").data("kendoGrid").dataSource.data();

$.each(dataSource, function(i, dataRow) {

dataRow.set("SomeBooleanColumn", true);

});

This causes an automatic sync back to the server, which is not desired, I would like to control this sync manually when the user hits save. When simply setting the "dataRow.SomeBooleanColumn = true" then attempt to save, nothing gets posted back at all.

Any help would be appreciated.

Bar charts in IE8

Hello,

we have a page which has two bar charts in it, and recently we noticed that the bar charts are not displayed in IE8 with the following error in the console :

SCRIPT87: Invalid argument.
kendo.dataviz.min.js, line 8 character 74552

Aside from the bar charts, in the same page we have also pie chart and several grids which are working fine.
Is there any such known bug with the bar charts in IE8, and if yes is there some kind of workaround for this problem?

Thank you, Alex Kolchev

dropdown in a grid

I'm looking at the the "foreignkey column" demo for the kendoui web grid. It looks like you can set the "values" property of the column to some data. My question is can you specify the "text field" and "values field" of the dropdown or does the format of the JSON data have to be "value" and "text"?

demo JSON:

var categories = [{

"value": 1,

"text": "Beverages"

},{

"value": 2,

"text": "Condiments"

},{

Difference between Content and LoadContentFrom

Hello

What is the different between Content and LoadContentFrom properties of Kendo UI's Window contorl. I have two button in Home page. Each button have separate window control to call corresponding partial view. If i use content method, the customer index loaded initially, ie at the time of page load. If i use LoadContentFrom, the DOM controls gets loaded when the window gets visible.

For example,
@(Html.Kendo().Window()
.Name("CustomerWindow")
.Title("Customer")
.Content(@<text>
@Html.Partial("../Customer/Index")
</text>)
.Draggable()
.Resizable()
.Width(736)
.Visible(false)
)

and

@(Html.Kendo().Window()
.Name("CustomerWindow")
.Title("Customer")
.LoadContentFrom("../Customer/Index")
.Draggable()
.Resizable()
.Width(736)
.Visible(false)
.Modal(true)
)

I think its lazy loading concept, but I don't know the exact difference.

thanks
Santhosh
