Is it possible to create a nested grid thorugh client code

[Chris Messineo]

Hi, I'm trying to reduce the initial load of my Hierarchical grid.  Right now it is about 180kb, I thought if I could create the nested grid on the client when it is needed the initial page load would be small.

I'm using this approach

Basically I'm using two web services on the client to load my master grid and the nested grid.

Thanks
Chris

Hello Chris,

I have prepared for you small example to illustrate you how to optimize this scenario - you can find the project attached.

Let me know how it goes.

Nikolay, thanks for the sample code.  That reduced my initial page load by 120kb

hey Vlaidmir,

   great post -- I've modified it for my purpose and all is good -- now I'd like to extend it (4 level hierarchy) and I'm hoping you (or someone) can give me a bit of help re: why 2 .js script files are required.  I'm new to .js and although I can see that the app does need them both, I'm curious as to why and also if i'm going to require more as I extend my hierarchy

 thanks in advance

Hello Brian,

Generally RadGrid does not support hierarchy out-of-box with client-side binding.
Provided solution to this thread as sample application and blog post demonstrates how you can attain such functionality. You can extend it in order to achieve your requirements.

   DO you have a this functionality with latest version of telerik controls i.e. nested grid through client code and expand at all levels and CRUD operation at each hierarchial level (all client side)?

Hello Aaron,

I am afraid that RadGrid does not support any kind of hierarchy by using client-side data-binding.
RadGrid transfer only JSON from client-server(Service/PageMethod)-client to populate RadGrid.
The only possible approach is to use server binding with client load mode as shown below:
