One checked child node per parent

[Darren]

I have a treeview that has Times as the parent nodes and Classes as the child nodes. I would like the customer to only be able to check 1 child node under each parent node. And I guess if they check a child node and another is already checked then I would like the other to be unchecked (maybe after a confirmation).

So, in the example below they could select Class1 and Class 11, but not Class 1 and Class 2.

Is this possible?

8AM
     Class 1
     Class 2
     Class 3
10AM
     Class 11
     Class 12
     Class 13
     Class 14
1PM
    Class 22
    Class 23

Thanks

Hi Darren,

I suggest you subscribe to the OnClientNodeChecking event and uncheck all nodes which have the same parent as the checked node. Please find attached a sample project demonstrating this approach. Download it and give it a try.
