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

[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
