Hi Satish J,
Find the answers below:
1) Get the child node given the index of a parent (first level).
- Yes, use the Items collection with indexer - e.g. Items[0].
2) Find the Node by name.
- Yes, use the GetItemByPath(string path) method.
3) Find the Node by Key (an alternate identifier for a node).
- Yes - use the TextSearch.Path property to specify the property which will be used as a key. See attached project.
4) Find the node by Index.
- same as N1?
5) Update a node fiven the node key and its parent Key.
6) Delete a node given its key.
- find the node and use the Remove method.
7) Select a node, given its key.
- find the node and use the IsSelected property
8) unselect a node given its key.
- find the node and use the IsSelected property
9)Check all the Parent nodes.
- find the node and use the CheckState property it will propagate to its parents.
10) check a particular node.
- find the node and use the CheckState property.
11) Check all the child nodes of a parent node.
- find the node and use the CheckState property it will propagate to its children.
I also attached a sample project which explains how to search for a node.
All the best,

Hi Valentin,
Thanks for your response. The sample project complains of a null reference while executing the method

GetItemByPath.
The following question was missed in the previous response. Would appreciate a response for this too.
1) Update a node given the node key and its parent Key.

Hello Satish J,
1) Update a node given the node key and its parent Key.
What do you mean by "update the node". Basically when you have the search API - you get a reference to the node and you can change its properties on the fly.
As for the project - please find attached the project with latest dlls.
Best wishes,
