|---X2
     |.....X11
     |.....X12
Y
|---Y1

Solution 1

Try this

C#

var node2 = TreeView1.Nodes[1]; // second node
           node2.SelectAction = TreeNodeSelectAction.None;
           foreach (TreeNode node in node2.ChildNodes)
           {
               node.SelectAction = TreeNodeSelectAction.None;
               foreach (TreeNode subnode in node.ChildNodes)
               {
                   subnode.SelectAction = TreeNodeSelectAction.None;

               }
           }

Thank you , I tried and this is working.

Can we have client side code for the same?
or instead of loop any option to disable child automatically on parent node disabling- For eg, In case if I don't know the level of child nodes...

without looping you cannot disable all nodes in c#
we can try using jquery.

Member 10112611 27-Apr-15 5:47am

Ok.. Can you help me on Jquery. I am not good at Jquery
