Rebond data source of hierarchy grid is not working properly

[Håkan]

Hi ,  I`m using Kendo hierarchy grid to my web page. When page loading my hierarchy grid id working properly.
 But in here I use a button to rebind grid data.
After re bond data, Its shows all parent rows. But my child grids are not showing when click the parent row. There is an error called "data is undefined".
I attached my aspx web page to here..

Please help me....

Hi,

 
From the provided information it's not clear for us what is the exact reason for current behavior. I would suggest to try setting the Ajax cache option to false as demonstrated below:

$.ajaxSetup({
    cache: false
 });

Also if the above change didn't help please provide small isolated example where the issue can be reproduced  - this would help us pinpoint the exact reason for this behavior.

Kind Regards,
Vladimir Iliev
