I am using rad grid in my application. I wanted to create a hierarchical rad grid where the no of levels of hierarchy will be known only at the runtime. The datasource for each detailsTable is generated in runtime. (Example can be that of a grid based on FileSystem (grid will display all subfolders in the current folder and so on) where the level of hierarchy will depend upon the subfolders present in a particular folder). Please help me with an example of how this could be achieved.
Thanks

When defining the structure of a hierarchical grid you should follow these rules:
- Create the GridTableView objects for every detail table. You do not need to create an object for the MasterTableView of the grid, as this is created automatically when the RadGrid itself is created.
- Add each detail table to the DetailTables collection of its parent table.
- Ensure that each table in the grid has its own data source.
Additionally, note that the hierarchical structure is not supported with simple data-binding (calling DataBind()).
The Basic steps that you need to follow in order to create hierarchical RadGrid programmatically in the code-behind are shown in the following help article:

I hope this information helps.

Thanks for the prompt response.I have gone through the url which you have provided. But my requirement is to display the folders from a file system with the created date. There might be "n" number of sub folders inside a folder. I need to bind them at runtime dynamically. I have done the steps which you have suggested. Please share me a working example to proceed further.
Thanks

I was not able to reproduce the problem and kindly ask you to open a formal support ticket and send me a small runnable application with the issue further isolated. As soon as I test it I will get back to you with additional information.
Looking forward for your reply.

Can u please share me any code sample for the dynamic hierarchial grid, where the number of rows will be known at runtime. Since i am running my code in Moss 2007. Everything works fine if i define the rows statically. but i wanted to create it dynamically. I have followed the steps from your reference url.I have to create the rows in the grid dynamically and also the sub level under it if exists. Please help me out.
Thanks
