I have a RadGrid that's losing the ability to sort columns by clicking the column header. I've narrowed it down to some code in my ItemDataBound method that updates the header text. If I remove this code, clicking the column headers works properly. But when I put it back, sorting is disabled. 

Here's my grid:

Here's my ItemDataBound method:

Any idea why this is happening?

Hello,

I have an application that has many different tables that need to be presented to the user - some of these have over 200k rows of data.

We currently use a very bad and basic search feature, along with .skip(x), .take(x) to only get a certain amount of data per page.

What I do above works, but lacks more advanced filtering.

I'm currently evaluating and looking at grid, but, I am very confused - it supports paging and by increasing the sample app to return 200k items, I can see through network monitoring that it only pulls the single page at a time, however, I'm getting lost trying to evaluate this product...

... The docs don't seem to go in to that much details and the demos page seems to be better, but neither give any information about performance tuning, limiting the result set and similar - I'm worried that if I link this to the live data, I'm going to introduce a lot of problems.

Are there any other documentation bits that I am missing?

1.when i change the Brower width, the text auto wrap and the row height grow. I want to set the text not wrap(see attachment), how can I do that.

2.I want to set text wrap in edit mode, how can I do that?

I am attempting to call a function in the controller when the Destroy button is clicked on a row. The controller will then delete the record in the database. I also need to pass in the ID of the employee to identify which record in the database to delete. Thank you!

This is what I have:

Hi there,

I am using a simple Kendo grid which contains a pop up form to allow a user to either add or delete new "categories" (many) for one product.

popup

I have altered the pop up to contain an additional "delete" button. As this extra button is not supported by the grid's inbuilt update function, I have used AJAX to capture data within the pop up held in a form and return it to the controller's separate "delete" method.

The pop up form code is contained on a partial view that looks like so:

And just for reference, the "Product" model like so:

I've added the delete button by using the grid's edit event to add the button dynamically via JavaScript:

So, when the user selects a category, they have the option to either add or delete a category from the selected "product". However, where "add" is handled by Kendo, I need to handle delete using AJAX.

The delete button is linked to the following JavaScript.

And the corresponding Controller method like this:

Hello. I have a problem with grid edit in line.

I have defined normal grid, which uses ViewModel.

ViewModel has 3 fields (int A, int B, bool checkbox) 

A field isn't editable by default but whenever I click "edit" I can change B field or check/uncheck checkbox.

I'd like to make field A make editable whenever checkbox is checked by user during edition. So after the checkbox is check A fields is editable.

Greetings

I have two charts, and I'd like to make it so the second chart updates when the series in the first chart is clicked. There's a master page with my RadAjaxManager, so I'm using a RadAjaxManagerProxy with these two charts. I'm having trouble converting the code samples I see in the documentation to work with my RadAjaxManagerProxy.

Here are my two charts:

Here's my JavaScript:

What I don't know is how to handle this on the server side. From the Implementing Drill-Down Functionality example, I have:

However, this line never executes. I'm missing a step here, and I was hoping you could point out what I need.

Thank you!

We are experiencing an issue with the virtual scrolling of a combobox when used as a custom editor template in a grid with in-cell editing. I have a solution to demonstrate the issue, but it is too large to upload.

Basically, when clicking into the combobox, the control is bound and looking at the web requests, the value is passed correctly to the ValueMapper and the index is retrieved correctly from the server. However, if you then TAB or press ENTER in the combobox, it attempts to retrieve the value based on the text in the combobox, clearing the reference.
