Grid not binding to Kendo Datasource

I'm trying to experiment with this grid to see if these kendo tools could be useful in our enterprise MVC 3 environment. I started up a new MVC 3 app in visual studio and added stylesheet links and jquery 1.6.2 to the head section in _Layout. Then dropped a kendo script reference in the index page and added some code to use the grid.

Grid works if I create the simple Star Wars html table in the examples and call .kendoGrid() on it. But it is not working at all with a div and datasource. Datasource is showing as populated in FireBug. I tried multiple ways to get this working, including initializing data in the kendogrid method, to no avail.

Please see attached screenshot. Should be able to tell from screenshot if there is a coding error. Any help appreciated. Should be easy to replicate as I had the same problem at home and in work environment. Will be happy to provide additional details.

Updating DropDownList Items Text

Hello,

I'm evaluating KendoUI for a project. One of the needs is to be able to dynamically update the text of the items in a DropDownList. With traditional HTML / JQuery, I can do the following:

<select id="myOptions">

<option value="0">Some Text</option>

<option value="1">Some Other Text</option>

<option value="2">Third Option Text</option>

</select>

...

$("#myOptions option[value='0']").text(getUpdatedText(0));

$("#myOptions option[value='1']").text(getUpdatedText(1));

$("#myOptions option[value='2']").text(getUpdatedText(2));

This works exactly as desired. I've tried something similar in Kendo, however, I haven't had any success. My most recent attempt looks like this:

<select id="myOptions">

<option value="0">Some Text</option>

<option value="1">Some Other Text</option>

<option value="2">Third Option Text</option>

</select>

...

$("#myOptions").kendoDropDownList();

$("#myOptions option[value='0']").text(getUpdatedText(0));

$("#myOptions option[value='1']").text(getUpdatedText(1));

$("#myOptions option[value='2']").text(getUpdatedText(2));

$("#myOptions").data("kendoDropDownList").refresh();

Unfortunately, the text of the options never updates. The reason I need to do this is because I need to update the text of the options on a regular interval. Can someone please tell me what I'm doing wrong?

Thank you!

Grid grouping not working on grid second initialisation

Hi,

I've run into a bit of an issue with the Grid on a second refresh of data.

I'm trying to do something a bit different as per the examples, and displaying the Grid through a different dataSource after every search on my site as it matches my coding structure better.

so I have:

Search -> Display grid + assign data source -> search again -> empty grid div (using $('#grid').empty()) -> display grid + assign data source.

This all works completely fine, other than it losing the actual grouping feature, the groupable panel shows but the grouping function no longer works.

Are there any workarounds for this?
