I have a KendoUI Grid that has a detail template defined. Is it possible to change the template on the fly?

I tried setting options.detailTemplate with a new template and also called refresh() but that didn't work.

Thanks,

victor

Validating and resetting a property in the View

I have a view with an input field that displays firstName. I want to apply some business logic to firstName. If the user violates the business logic, I want the view to display the "current" value for firstName.
.
Here is the view:

<div id="personFields">

<div class="field">

<div>First Name:</div><input data-bind="value: firstName" required />

</div>

<div class="field">

<div>Last Name:</div><input data-bind="value: lastName"/>

</div>

<div class="field">

<div>Full Name:</div><span data-bind="text: fullName"/>

</div>

<button data-bind="click: reset">Reset</button>

</div>

Here is the ViewModel:

var person = kendo.observable({

firstName: "John",

lastName: "DeVight",

fullName: function() {

return this.get("firstName") + " " + this.get("lastName");

},

reset: function() {

this.set("firstName", "John");

this.set("lastName", "DeVight");

}

}).bind("set", function(e) {

if (e.field == "firstName" && !e.value) {

e.preventDefault();

}

});

kendo.bind($('#personFields'), person);

When I change firstName to an empty value, the input field remains empty.

I tried changing the handler for the set event to this:

function(e) {

if (e.field == "firstName" && !e.value) {

var field = e.field;

var currVal = this.get(e.field);

this.set(field, currVal);

e.preventDefault();

}

But the input field still does not get reset to the "current" value. How do I do this?

How to use the .less output from the themeBuilder

Hi,

I've generated a less file via the theme builder and as written there (http://docs.kendoui.com/getting-started/themebuilder), I,ve also added the template.less to my project. So right now I have the following files :

- mixins.less
- kendo.default.less
- common.less
- template.less
- and finally my custom.less generated via the theme builder.

When I launch my website, I've got this error message :

variable @widget-background-color is undefined

in template.less on line 106, column 23:

105
```
{
```

106

    background-color: @widget-background-color;

107
```
}
```

What am I missing ?

Thanks

Backbutton appears on every page

Hi,

when I use the following layout for all my views I realized that the Back button appears on every view.

<section data-role="layout" data-id="default">

<header data-role="header">

<div data-role="navbar">

<a class="nav-button" data-align="left" data-role="backbutton">Back</a>

<span data-role="view-title"></span>

</div>

</header>

</section>

As far as I remember "jQuery mobile" automatically hides the back button on the first view by default - which is great because I surely don't want a back button on my first view.

Having the back button even on the first view, is that by design in Kendo mobile?

Thx
Ingmar

DateTimePicker DataSource

I am trying to bind a DataSource to my DateTimePicker widget but I'm somewhat at a loss as to whether this actually works and how the data could be defined. Currently I'm using the following code.

var timeSource = new kendo.data.DataSource({

transport: {

read: {

url : "/cgi-bin/system.cgi?time",

dataType : "json"

}

});

$("#datetimepicker").kendoDateTimePicker({

dataSource: timeSource

});

And the server is returning json with the following format, I can change this part easily but I'm not sure what DateTimePicker is expecting.

[ { "time" : "Wed Oct 24 10:26:46 MDT 2012" } ]

Calling a custom method after grouping by column

I am performing validation on missing data when loading the grid and applying a red border to a cell where the data is missing so the user can identify missing data quickly. I have my grid groupable = true so the user can group by column headers. My problem is I lose the cell border after the user drag/drops the column header into the "Drag a column header and drop it here to group by that column" area. Any ideas on what fires after the grouping is done or where I can insert a custom method to reapply my cell border.

Endless Scrolling: Invalid template: <a href ...</a>

Hi everyone!

I have this endless scrolling component but in my case I want to make every <li> clickable, so i designed this template:

...
<script id="endless-scrolling-template" type="text/x-kendo-template">
<a href="#overview-account">
<div id="parent">
<div class="img-div">
<img src="../../content/mobile/overview/nairobi.jpg" />
</div>
<div class="name-div">random_string</div>
<div class="url-div">random_string</div>
<div class="dist-div">random_string</div>
</div>
</a>
</script>

But when the page is rendered nothing is displayed...

If I remove the <a tag like this:
...
<script id="endless-scrolling-template" type="text/x-kendo-template">
<div id="parent">
<div class="img-div">
<img src="../../content/mobile/overview/nairobi.jpg" />
</div>
<div class="name-div">random_string</div>
<div class="url-div">random_string</div>
<div class="dist-div">random_string</div>
</div>

...everything is ok but the elements are not clickable :/

This is the exception:
Thank you all!

Uncaught Error: Invalid template:'<li data-uid="#=uid#"> <a href="#overview-account"> <div class="parent"> <div class="img-div"> <img src="../../content/mobile/overview/nairobi.jpg" /> </div> <div class="name-div">random_string
</div> <div class="url-div">random_string
</div> <div class="dist-div">random_string
</div> </div> </a> </li>' Generated code:'var o,e=kendo.htmlEncode;with(data){o='<li data-uid="'+(uid)+'">\n <a href="';overview-account"> <div class="parent"> <div class="img-div"> <img src="../../content/mobile/overview/nairobi.jpg" /> </div><div class="name-div">random_string

Layouting Popup Edit Forms

Hello,

for testing purposes i just try recreate a simple input mask from a former application in Kendo UI. Unfortunatly i couldn't find any ressources on how to layout and expand the editor pop window.

How can i realise this (ar at least similar) input mask in kendo ui popup editor?

And is there a image selector widget?

And last question. In my popup window template i alway get this js code in the headline. How can i avoid this?

function anonymous(data) { var o,e=kendo.htmlEncode;with(data){o='

Thanks in advance

Btw. The example is a real 'Kendo' page.
Kendo UI seems like real kendo, you need keiko, keiko, keiko ... :D

How do i bound null object value

Hi I am trying to

columns.Bound(f => f.Admin_Menu_Group.Name ).Title("Admin Menu Group");
or
columns.Bound(f => f.Admin_Menu_Group != null ? f.Admin_Menu_Group.Name : "").Title("Admin Menu Group");

But error "Bound columns require a field or property access expression"

Because Admin.Menu.Group field is null.
