Hi,

Thank you, this code worked fine, however, partial solution, I was after the complete solution. i.e. RadTAbStrip, Multipage, loading data from the database etc etc,  I want everything u see in that demo written programmatically.

Sorry for asking so much!

Thanks

Hello,

Sorry for late.

Programmatic creation of RadGrid / Hierarchy with Templates

let me know if any concern.


Thanks,

[Dean]

Thank you so much! very helpful!

I have a request, in the real world child rows in the hierarchy should only be executed after the user has expanded the row, how could you get your example working so the child rows only get executed after the row has been expanded?

At the moment you have the overhead of running code in the next hierarchical level even though the user hasn't expanded the row...

Thank you

I want 2nd layer (tabs) to only load on demand. I want child view to only load when user expand's the grid row.

[Jayesh Goyani]

Hello,

innergrid.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;

let me know if any concern.

Thanks,
Jayesh Goyani

[Dean]

Thank you. How do I use your code to make contact information ie date of birth load when the user expands the parent row?

[Jayesh Goyani]

Hello,

RadGrid1.MasterTableView.HierarchyLoadMode = GridChildLoadMode.ServerBind;

if this is not your case then elaborate your scenario.

Thanks,
