Hello,
I'm new in KendoUI and I have one small question.
Is there any way to get Url paramters from Grid paramters? What I need to do is to catch each user action on a KendoUI Grid (actions like sorting, grouping and filtering) and replace the current page Url without refreshing. In this case, users can then easily share their views.
Can you please let me know if you have any recommandation, or native feature to help me doing that.
Thanks & regards.

I have a HTML page that contains a kendo grid showing many pages. I need remember the grid page number inside the kendo grid in code so that I can go back to the grid page from other HTML pages. How can I access the grid page property when the grid page number is clicked?
Thanks in advance.
Thanks in advance.

Hi,
I am looking for a way to assign color to a legend field. Please take a look at http://jsfiddle.net/ashriva/Cke4n/3/
In the above example I am trying to assign green color to the "Short" legend element to match its value field; similarly "Long" should be blue and "Flat" red.
Any help is greatly appreciated.
Thanks!

I'm trying to do use the hierarchical aspect of the Kendo Grid. What I'm unable to find out is if when I make the Detail template do the children need to be already loaded from my repository? I thought since there was a Data-source it would make the call to the server get the children when it was loading. The Template grid has is null and there are no query strings (as followed by the example) Can I get some clarification on this please?

Is there a client-side method to force a tree node to clear and then re-load (or refresh) all child nodes? I am dynamically loading a tree view and it's child nodes via AJAX. When I add a node, I call another AJAX method to add the node to my database. I would like the treeview/node to then refresh itself and automatically call the dataSource.read method for the node.
Thank you.
*** EDIT ***
I have found a solution that mostly works:
var treeView = $('#catalogTreeView').data('kendoTreeView');
var selectedNode = treeView.select();
var selectedDataItem = treeView.dataItem(selectedNode);
treeView.collapse(selectedNode);
selectedDataItem.loaded(false);
treeView.expand(selectedNode);
However, the expand does not always work and the node stays collapsed. Is this the correct way to do this, or is there a preferred method?
Thank you.

EDIT: solved with 2013Q1 by adding grid.wrapper.empty()
Sorry, I cannot get this working on jsBin but it works locally on my PC. It should be easy enough to assemble on your end.
In addition to grouping issue, the column-sort seems to have three modes: A-Z, Z-A, and random order.
Am I doing something wrong, or incompletely, when I destroy the grid in my SimulateSearchResults function?
NOTE: This problem is with 2012 version. When I use 2013 Q1, different issue -- a phantom column is created.

Hi
I'm trying to convert my site to utilise Kendo Grid, I'm trying to add a <div> that calls a javascript onClick using Column template but the javascript isn't being called. I suspect that it might have to do with how the data is loaded. Any idea on how I can add a clickable div through column template.
Also, how do i utilise Template instead of ClientTemplate ? what are the differences ?

Hi,
I want to diable in-cell editing. I.E., I do not want user to double click on the cell and edit it.
However, if i disable editable, I am not able to perform row remove.
I have added remove functionality and edit functionality in a column like in this example.
http://demos.kendoui.com/web/grid/editing-inline.html
I am not using editable: "inline", in stead I am using editable: "true"
Because I want to prevent default
(e.preventDefault) and write my own functionality.
Can you help me with this
All I want is
1. Non-Editable cells
2. Edit and Delete works as per above example
3. Edit default functionality to be overwritten with mine
Please help me with this
Thank you

I have mis-wired up my update call...so in firebug I see the ajax call just tank, however the client object updates perfectly fine...idea is there's no "save" button changes are reflected instantly.
Am I missing this option in the docs? autoSync doesn't seem to do it (or maybe is *causing* it)

Hi,
I've created a Scatter chart in ASP.NET MVC with the code below:
The above is calling a method in the Products controller below:
The chart will refresh when a new country is selected by the script below:
However, the page will freeze at times due to a "long running script". The DataSource of the chart calls the action GetProductsCountByCountry and groups the data. I want to do the grouping on the server side but I'm not sure how to change the code for my chart for dynamic series without doing what I'm currently doing.
This is the first time I'm using Kendo DataViz and I really could use some help.
Thanks!
