Not working "Frozen column" in Kendo UI For ASP.Net MVC

Hi,

i'm using Kendo.Mvc version 2015.1.429.440 (Q2 2015), but when I use Locked(true) to a column,

it doesn't get frozen. I'd like to know:

- what is doing wrong in my code

@(Html.Kendo().Grid(Model)
         .Name("grid")
                 .Columns(columns =>
                     {
                         columns.Bound(typeof(string), Model.Columns[0].ColumnName.ToString()).Locked(true);

                         for(int p=1; p< Model.Columns.Count-1; p++)
                         {
                             columns.Bound(typeof(string), Model.Columns[p].ColumnName.ToString())
                                 .Width(150)
                                 .Encoded(false);
                                 //.ClientTemplate("<img src='" + Url.Content(column.ColumnName.ToString()) + "' />")
                         }
                     })
        )

thanks for help in advance.

Nested Items within a PanelBar

Hi

How do insert a control within a Panel.

As an example below with the Panel Getting Started I would have the text "Testing" and then a Kendo.button underneath ?

<h3>Telerik UI for ASP.NET MVC PanelBar</h3>

<br />

@(Html.Kendo().PanelBar()

.Name("IntroPanelBar")

.Items(items =>

{

items.Add()

.Text("Getting Started")

.Selected(true)

.Expanded(true)

.Content(@<text>

Testing

//button here

</text>);

items.Add()

.Text("Add NuGet packages and jump-start your coding")

.Content(@<text>

<p style="padding:0 1em">NuGet makes it easy to install and update free libraries and tools.

<a href="http://go.microsoft.com/fwlink/?LinkId=245153">Learn more…</a></p>

</text>);

items.Add()

.Text("Find Web Hosting")

.Content(@<text>

<p style="padding:0 1em">You can easily find a web hosting company that offers the right mix of features

and price for your applications.

copy node + children

dear community,

I'm facing the following issue right now:

within my TreeView it should be possible, that every node and all its children can be copied within the same tree. Therefore I've setup a button which calls a function that tries to copy the node + its children.

The function looks like this:

function CopyTreeViewItems() {

var treeview = $('#treeview').data('kendoTreeView');

var selectedNode = treeview.select();

var data = treeview.dataItem(selectedNode);

var newData = {

id: GenerateGuid(),

Name: data.Name + "tmp"

};

treeview.insertAfter(newData, selectedNode);

var parentItem = treeview.dataItem(treeview.findByText(newData.Name)); //<--- this part is returning 'undefined'

if (data.hasChildren) {

var children = data.children.data();

for (var i = 0; i < children.length; i++) {

var add = { id: GenerateGuid(), Name: children[i].Name };

treeview.append(add, parentItem);

}

The parent node is copied without any problems. If there are children of a parent node I'm not able to append them to the corresponding new parent.

Any advices?

Kind regards

Tom

Decimal separator ignored with de-De culture.

Dear Telerik Team!
I've got an essential problem updating a decimal value in a grid.

The model property is annotated wird a weight datatype attribute

[DataType("Weight")]
public decimal WeightGross { get; set; }

And the Editortemplate for weight is this:

"
model decimal

@(Html.Kendo().NumericTextBoxFor(m => m)
.Spinners(false)
)
"

The Problem ist the following: When the culture ist set to "de-DE" the value cannot be correctly updated. The decimal separator is ignored!
If I edit the grid row and enter e.g. '3,25' following happens:
- If I press Tab to go to the next colum the value is correctly shown as '3,25'
- But If I click Update, the value submitted to the controller is 325!

I think this has s.th. to do with the fact that the decimal separator is ',' and not '.' with "de" culture.
If I change the culture to "en" and use '.' as decimal separator it works.
Am I missing s.th or is this a bug in the framework?

brgds
Malcolm Howlett

p.s. If I omit the Datatype annotation it does not get better:
- I can use ',' as the decimal separator in edit mode
- but after moving to the next column the value is displayed with '.' decimal separator
- When submittin the decimal separator is still ignored. 3,25 (3.25) becomes 325.

Treeview with checkboxes on the second popup

Configuration :

Main page with grid, editable.Mode(GridEditMode.PopUp)

This Popup page also have grid with PopUp mode, last Popup page have Treeview with property .Checkboxes(true)

This popup windows newer appear.

To fix the situation have to delete .Checkboxes property from TreeView . As workaround delete Checkboxes and use TemplateId with scripted template and .ToClientTemplate for treeview.

But this situation definitely Kendo ui bug, and have to be fixed

I have a grid inline with two fields "OrigenId" and "DestiID". These fields uses foreignkey and two templates named "GetOrigenOnPlanning" and "GetDestiOnPlanning". Now I explaind to you that I need, the data inside in template will be different in function if user selects update or create. The problem is I don't find a event is traggered before the data are inserted in dropboxlist, I tested with event edit or event push of the datasource object.

GRID

.Name("expedition")

.HtmlAttributes(new { style = "margin-bottom:10px;" })

.Scrollable()

{

t.Create().Text("Afegir Expedicio");

}

})

.Columns(columns =>

{

columns.Bound(f => f.ExpeditionID).Width(90);

columns.Bound(f => f.Data).Width(100);

Turn grid caching off for IE using web API

I have an IE problem with caching that i've seen many different places. My grid works fine on chrome/firefox, and it loads fine on IE. but if i add a new row set of data, the IE grid refresh doesn't show it. It's caching and I don't have a way to turn it off. The options i've seen on your site are:

set output cache to nostore ( http://www.sliqtools.co.uk/blog/net/asp-net-mvc-disable-cache-to-keep-ajax-working-ok/ ) , but this option is ONLY available in the MVC controller, not Web API.
use cache:false (https://stackoverflow.com/questions/14975103/how-to-disable-read-request-cache-in-kendo-ui-data-source). This option isn't available as an MVC wrapper though.
use HttpPost instead of HttpGet ( http://www.telerik.com/forums/prevent-ajax-caching-on-read ) . This option actually does work, but it breaks paging. For some reason it shows ALL rows in the grid, but still shows the paging at the bottom as if it was only showing 10 rows. Very odd, and totally broken (clicking on any of the paging buttons does nothing).

Are there any other options out there for an MVC Wrapper, Web API datasource that can't use HttpPost?

Edit multiple models in one UI

I've searched around but haven't found a concise example for this yet.

I have an object graph with nested data such as coming from Entity Framework
Parent
Multiple Children
Multiple Children

I need to provide the user a way to modify/create the parent as well as the children in as simple a way as possible in a single UI. How can I accomplish this using Kendo MVC with MS MVC 5? If possible I'd rather not manually create a ViewModel and have to do translation between the object graph and the ViewModel. If that's the only solution then I guess that's what I have to do but I was hoping to be able to use the EF model directly. Any suggestions are greatly appreciated.
