Questions on Kendo UI for jQuery Forum

Very surprised I couldn't find more information on this. Most grid libraries allow direct js functions for their column renders. In the case of Kendo UI it must be a string template, which is quite limiting. The problem I am currently facing is this:

// Inside my view

config: {

a: "A",

b: "B"

},

foo: function(data) {

return this.config[data.config];

},

initGrid: function() {

this.ui.grid.kendoGrid({

columns: [{

title: "Column A",

field: "columnA",

template: "#= this.foo(data) #"

}]

});

}

I have no way to access a member method in my template. This is crazy limiting. ANY of the following scenarios would be workable:

// Direct function access

template: this.foo

// Set scope of template execution

template: { template: "#= this.foo(data) #", scope: this }

// Templates always executed in scope they are defined in

template: "#= this.foo(data) #" // Just works

The current requirement that only global methods can be called is severe (not to mention a terrible practice). Please advise on how to circumvent this limitation.

grid.dataSource.data() doesn't return all remote data

Hi,

The documentation for the data() method of the dataSource states that it will return the service response. However, if I make this call from the dataSource on a grid, it only returns the data the grid is bound to - not all of the data that was returned from the remote service to the dataSource. How can I get the complete data returned from a remote service to a dataSource that is bound to a grid?

Thanks,
Josh

How to refresh an item in a datasource with server data?

Hello,

I have a datasource filled with data. And now I want to refresh a data-item because I know it has changed at the server. How can I do that without reloading the complete datasource?

Thanks, Jaap

Resources - I don't understand the mapping

In the scheduler demo, how are the resources mapped from "Text, Value, Color" to "ownerId"?

resources: [

{

field: "ownerId",

title: "Owner",

dataSource: [

{ text: "Alex", value: 1, color: "#f8a398" },

{ text: "Bob", value: 2, color: "#51a0ed" },

{ text: "Charlie", value: 3, color: "#56ca85" }

]

}

]

Here is what I am trying to do, I have to transform my data and I don't understand how to maps this example data source to"ownerId"?

resources: [

{

field: "ownerId",

title: "Owner",

dataSource:

{

type: "json",

transport:

{

read: {

url: "/api/_Users?filter=(IsUser%20eq%201)",

type: "GET"

}

},

schema:

{

parse: function(response)

{

var users = [];

var inner = response.results;

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

{

var user = {

text: inner[i].Attributes.FirstName,

value: inner[i].Attributes.Id,

color: "#ff0000"

}

users.push(user);

return users;

}

]

License terms & Open Source

Since I bought (and used) a license to develop ASP.NET/Razor solutions, people keeps asking me what is 'free' and what is to paid to Telerik, since it seems that runtime components are 'open source' and 'freely available' to customers...
I don't know what to answer, and I admint that the price I paid for the library is largely paid back for the wonderful support I got from Telerik.
Nonetheless, I would like to know the 'right' answer to give, to people that think that they can use JS components for free.
Is there anyone that can clarify the situation?
Thanks in advance, for myself, and the others! :-)
Andrea Bioli
P.S.: I see that I can even download a nuget package, called 'Telerik Kendo UI Web'... is it free, or what?

Not all button clicks are registered

I am declaring buttons like this:

<span data-role="button" data-click="on_button_clicked">Button</span>

the problem is that not all button clicks result in a call to on_button_clicked.

The problem is illustrated on this fiddle.

If you alternate clicking those two buttons fast, you see that not all clicks are registered, even if the physical appearance of the buttons reflect the clicks.

Possible to disable certiain items?

Is it possible to disable certain items within a multiselect? This way they appear, but are not selectable.

I have a scenario where certain selections in a mutli-select preclude others. As a fall back position I can just filter down the raw data so certain elements just don't appear.

Recursive kendo template

Hey,

I have a grid that has a clientdetailtemplate. In that template, i use another grid, that would call the same template again untill maybe 3 levels down.
Is that possible? I get invalid client template, but thats maybe it is just not possible by design. When i add .toclienttemplate on the grid, it does not give an error, but nothing seems to happen.

<div id="dvResults" class="searchResults col-md-6 col-md-offset-3">

<div id="resultGrid">

@(Html.Kendo().Grid(Model.SearchDetails)

.Name("grdSearch$Results")

.HtmlAttributes(new { @class = "grdSearchResults" })

.Columns(column =>

{

column.Bound(x => x.Icon).Template(@<text><img src="@item.Icon" class="searchicon" /></text>).Width(16);

column.Bound(x => x.Name).Template(

@<text><a onclick="SelectEntity('@item.CustomerId','@item.PremisesId','@item.InvoiceStructureId')">@item.Name</a>

@if (@item.IsCustomerLevel)

{
