make the tab seleted by default

[Sudhakar]

Hi Team,

I have a grid with some rows in it. When I expand each row I am displaying the 3 tabs.
I wanted to implement the following scenario.

1)Based on some predefined values(we defining them in enumerations.cs file)need to select the one of the tab by default.
If the enum value is zero need to make the  second tab selected by default and if the enum value is 1 need to make the third tab selected by default.

I am using the telerik dll version of 2014.3.1216.45 and implementing batch editing functionality.

Hello Sudhakar,

Can you please refer to answer from 29-Dec-2014 in ticket with ID: 876775, where I have explained in details how you could achieve such behavior:

"Since your HierarchyLoadMode is set to ServerOnDemand, once you expand an item you can get reference to the NestedViewTemplate withing the server-side OnItemCommand event handler and depending on your enumeration, to select a specific RadTab in the RadTabStrip control..."
