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

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.

How to use Kendo Grid Ajax Read event on demand

Hi All,

I have page with DropDownList and Telerik's Kendo UI Grid Control. When first time page is opened DropDownList has no item selected in it. When user selects value in DropDownList only then Grid should make Ajax call to the server and load corresponding data.

My code works fine when user selects item in DropDownList, but the problem is that first time when page is opened I there is no value in DropDownList and Grid should not make a call to the server.

My question is how can I prevent grid not to make a call to the server if there is no item selected in DropDowList?

Thanks a lot.

Application using Kendo UI for Android Tablet

Hi,

We are developing an application for Android Tablet using Kendo UI. Grid and Drop down lists are the commonly used components in our application. We are populating data in the grid and drop down lists from the Android inbuilt SQLITE database. For that we are currently switching from the .html file to the .java file where I have written the query for fetching the data and return back to html page for rendering the data on the screen. The screen transition seems to be very slow. Also we have link templates for the fields in the grid using which navigation to pages is done. Can you please help me to reduce the time it takes to navigate between pages.. ?

Thanks for the help in advance.

Foreign key with the "values" property of the column

I see the grid demo has a "foreign key" option where the "values" property of the grid column can point to a data-source, and will automatically build a drop-down widget for that column. I also saw in a forum post where Telerik says the values object must have 2 properties (value and text).

The grid documentation page mentions nothing about the values property. Is it documented anywhere???

Inline editing of UK date in grid

I have a grid which takes a date from a MySQL database in the format year-month-day hour:minute:second and displays it as a UK date in a datepicker in the grid. This seems to work fine.

As soon as I go to edit the date in the inline editor though, I can make the change but it the editor immediately exits, taking me back to the original grid.

It is worth noting though that I am using jQuery 1.8.2

Just wondering if anyone else has seen this before?

My grid along with all of the code is here:
