Hi,
today i have tried to read the data out of a datasource....
i have just seen this post: http://www.kendoui.com/forums/framework/mvvm/mvvm-source-binding-to-datasource.aspx
which is bascially what i have been trying to do all day.
tho trying the answer doesn't work, when using kendo.bind($("#container"), a); it Never hits the controller action method (using MVC3) leading me to believe that the datasource never calls the server.
I have had limited success creating a datasource and calling read() on it, but could never get the data out afterwards.
what im trying to do:
1) define #view with binding templates
2) read remote datasource
3) bind that data array (from item 2) to a viewModel property (viewModel.Groups = data???)
4) bind the viewModel to the view (using
I have foudn this very hard to do...
I should say im a Noob to javascript so maybe im making a basic silly mistake... but for the life of me i can figure out what.
Thank you in advance

i am using Firefox and firebug. firebug is not showing ANY call to my controller. (other than the first call to load the page)
i have forced the read (using a.theList.Read()) and it returns with the following data:

[{"ID":0,"Name":"Larocque"},{"ID":1,"Name":"St-Louis"},{"ID":2,"Name":"Dorval"},{"ID":3,"Name":"St-Pierre"}]
(and the breakpoints on the controller hits)
but even doing this, nothing is showing in the list on screen using the data template other than the words
undefined.
The scripts i am using for this are:
jQuery 1.7.2- kendo.web.min.js
- kendo.data.min.js

I just had the same issue... I was using kendo.web.min and kendo.dataviz.min together. Switching to kendo.all.min solved the issue.
