I am giving option LTR and RTL text direction in Kendo Editor.

While clicking on particular icon, i have to get the selected area text and apply dir=rtl or dir="ltr" to the selected element. But i can able to get the selected text with the following code.

$(this).data("kendoEditor").getRange()

But i have to select the tag of this selected area and apply the direction attribute.

Can anyone help me to resolve this?

It looks like by default creating a dataSource with a data array automatically loops through the entire array and does some operations on all of the members.  Is there a way to suppress this or have the reading of the elements controlled by a function?  I do not want the data source to access all of the members until it has a need to do so ... maybe this need is present and I'm just unaware of it.  I have an array that I want my data source to operate.  This array lazy loads its values at the time they are accessed.  I am giving this data source to a grid with a pager. I do not want my data source items to actually load until the pager / grid needs them for display.  Unfortunately I cannot use server side paging ... I must do this all through the client.  Can anyone think of some ways this can be accomplished, either through manipulating the data source and a pager, or maybe by mocking server side paging requests in the client?  Any help would be appreciated.  

I write my codes in html is OK,but when I bind the datasource using javascript,it is not ok.What's wrong with my codes?

**My View:using Meetings_Read is OK,but using javascript is not OK**

     @(Html.Kendo().Scheduler<SchedulerCustomViewDemo.Models.SchedulerTest>()

    })
    .DataSource(d => d
        .Events(e => e.Error("error_handler"))
    // .Read("Meetings_Read", "Home")
    )
    )

**My Javascript:it is not OK**

Hi, 

At first, I understood that the "onDataBound" event of the TreeView would indicate that my tree is "ready".
However, this is clearly not the case, and I'm wondering if there's nothing else I can use or if this is a known issue.

I use a hierarchical data and a transport/url to read the data (see code snippet below).
The OnDataBound event throws alright, but at this point in time, nothing can be done on the tree. Expanding items, looking for items. Nothing.
I currently put a 1500 millisecond timeout inside the OnDataBound and then call "expand" on the tree's first node... this which works most of the time - but not always, depending on the network.
Which means, the onDataBound is not even close to the event I need.
Is this expected/known or am I missing something here? Is there an event that I can use to indicate that the tree is ready (at the moment I just want to expand all nodes, eg -> tree.expand $("#treeName .k-item:first") and this doesn't work)

_treeViewDataSource = new kendo.data.HierarchicalDataSource(
  transport:
  read:
  url: options.dataUri
  dataType: "json" 
  data: postData
  cache: false

I got a mvc grid with a popup editing feature. Inside my popup with is a mvc template I need a area do add child to a collection. I think I need a template but I don't know wow to implement it. The problem is that with this section the popup is invalid because in not part of the main model. How can i put this in the main template without making the popup invalid. I'm hiding and showing this area with javascript.
Thanks in advanced!!!

Rick.

Hi,

Our datasources data are generated with nested objects from the server and sometimes, some values can be null.

At first, I had to do custom template functions for every column to display them according to their values, so I created a function that either returns the value of the object, or an empty string if on any given level, it is null. However, if I try filtering that column, an exception is thrown.

I have created a sample code to show this error, just try adding a filter to the column to see the error : http://jsfiddle.net/UXBcW/1/

Thanks

I have been working on this the last few days, and am very new to Javascript and Kendo UI.  I have created my WCF and it is working fine. When I go to the URl/FunctionName I get a list of the Employee data returned.  Below is a paste of that data...

[{"FirstName":"Nancy","LastName":"Davolio"},{"FirstName":"Andrew","LastName":"Fuller"},{"FirstName":"Janet","LastName":"Leverling"},{"FirstName":"Margaret","LastName":"Peacock"},{"FirstName":"Steven","LastName":"Buchanan"},{"FirstName":"Michael","LastName":"Suyama"},{"FirstName":"Robert","LastName":"King"},{"FirstName":"Laura","LastName":"Callahan"},{"FirstName":"Anne","LastName":"Dodsworth"}]

However, when I try to get this data using my ASP.NET website project, it does not load correctly.  I dont know if I am doing something wrong in the filling of the grid, or the calling of the WCF itself, so I decided to try to ask here as I am out of ideas.  The errors that come up in Chrome debugger are as follows...

"OPTIONS http://localhost:27689/Service1.svc/GetDataUsingDataContract?_=1398887165670 405 (Method Not Allowed) jquery-1.9.1.js:9597
XMLHttpRequest cannot load http://localhost:27689/Service1.svc/GetDataUsingDataContract?_=1398887165670. Invalid HTTP status code 405"

However, when I click on the http://...... it shows on the browser fine.


Below is a copy of my Web Page Markup. If anyone could please tell me what I am doing wrong, it would be much appreciated.  Below the markup of my page, I am also going to put the Interface of my WCF, the Config of the WCF and the code behind the interface so that just in case that is the issue, someone will have it available to help.  Thanks.

I noticed that when I use virtual scrolling with the example of frozen columns (http://demos.telerik.com/kendo-ui/web/grid/frozen-columns.html) using the MVC syntax, the rows are out of sync when I scroll to the bottom.
It appears as there is no blank space below the table with the frozen columns when a horizontal scrollbar is show in the non-frozen columns

Quite new to MVC and kendo and was wondering if there was a way to prevent panelbar from creating duplicate items and whats the best method to achieve this.

Here is my panelbar markup:

Here is my class markup for the model:

And here is my controller action:

Is there anyway in the controller action or actual panelbar markup to select DISTINCT category?  My model returns multiple rows which could have different or the same category.  Or is there a way I can check if the item with certain text exists already and not create it?

Also am I going about this the wrong way and do I need to have a separate model just for categories?
