The documentation doesn't seem to mention anywhere which properties of the grid are available.  I'm trying to find out the current page number the grid is on so I can add it to a cookie or something.  I need to be able to put users back on the grid page they left.

In an ideal world, I'd like to be able to use the current page number in a column template, something like

When I hover any of the lines (not the data points), I notice the javascript error:  b.value is undefined, being thrown repeatedly in Firebug. I'm using Firefox 13.

In IE9 the error is:

SCRIPT5007: Unable to get value of the property 'toString': object is null or undefined

I have a big problem populating a kendo combobox with json data sent from controller in an ASP.NET MVC3 project.
My controller:


I am modifying the returned string to be an array of objects (dataSource works only for arrays from what I have read)

In the html file:

In the attachment below is the json the controller returns. The combobox control doesn't show anything, just the loading image in the right.

It's a problem with the Json? If I declare it locally, it works (in firebug appears like an object array of objects). The dataSource can't parse it? It's because of the json is like a string, in the " ? I don't know what the problem might be, I spent too many time trying to understand this..

Please help! Thanks!

Hi folks,

This is my first doubt on Kendo UI Forum, and I will appreciate all you guys help!

I tried to populate a DataSource based on a XML File. If this DataSource is used with a Grid, it works well, therefore I can´t use It again with a form.

I also got an error executing my code...

Here is my complete source code:

HTML


XML File


Kendo UI JavaScript


Thanks!

If I specify my grid headers like this:

I would expect that since I'm telling it which field to match up, that I could control the order that the data item displays in.  However it seems to render the columns based on the JSON property order instead.

So lets say the above is the correct order the json is coming down in, if I swapped the first two header items, theyd render swapped, but the data would bind as it did before, so the pdrs would be in the rotations column and visa versa.

I'm trying to get the Kendo Grid operating in the 'client operation mode', as in the Telerik Extensions for ASP.Net.  This is where the grid makes only one request to the server, retrieves all the data, then performs all operations (paging, sorting, filtering and grouping) client-side.  Does anyone know if this mode of operation supported in the Kendo Grid?  Many thanks in advance. 

I have been struggling to bind an AutoComplete datasource to an AspNet web service throughout the day. But the web service is not called at all. The error routine shows "Internal Server Error" alert.

Both the web page and the web service are in a folder named "AutoComplete" under the root directory.
Could anybody please help me?

MVVM binding, json has 10 columns, I only need to show 5 of those...

I've tried "visible" or "width" on the header bindings with no success...can it be done?

Hi. 

We are looking at Kendo UI for our new web offering. 
We have grids in our system which can easily contain 100K rows or more.
We do not want paging.  We want to be able to scroll across all rows without interruption.

I modified the basic grid example to generate 100K rows and set the page size to 100K.
The grid took around 4 minutes to load and then was unresponsive to user interaction.

Is there a way to specify a true virtual mode so that the data source size becomes unimportant?

Take care,

Ken Rubin

What am I doing wrong here...?  syntax problem perhaps?  It's properly 3 times, but the name only shows up twice, and it's not binding the children to the proper area.

Seems straight forward?
