I'm sure this is simple but it's got me foxed.
I want to add a child node to a child node.

I store the location I want to place the new node, in this case parent node 0 and child node 0

If r("DocNode1") = 0 And r("DocNode2") = 0 Then

End If

Thanks.

Isn't it just typical, after you search for hours for an answer, then go to the trouble to ask for help, five minutes later your crack it.

Good afternoon,

I am currently facing the exact same problem as Gary Robson, however, I am under these conditions/restraints;
>>I do not know how many 'grandparent' does the node has. Meaning... it could be something like;

-Node1
|--Node2
|----Node3
|--Node4
|----Node5
|----Node6
|------Node7

In this case, for example, if I am at Node7, my parent is Node6, grandparent is Node4 and great-grandparent is Node1.
Assuming I do not know about grandparent Node4 and great-grandparent Node1...
Am I still able to add? My 'expected' result is;

-Node1
|--Node2
|----Node3
|--Node4
|----Node5
|----Node6
|------Node7
|--------[Node8]

I have tried using 'Insert', but it would put Node8 at the same level as its parent, Node7, giving me this;
-Node1
|--Node2
|----Node3
|--Node4
|----Node5
|----Node6
|------Node7
|------[Node8]
Ranking Node8 and Node7 to be sibling-level, and not parent-child.

I appreciate all help given.
Thanks and yours sincerely,
H. Vi

Hello H Vi,

Thank you for contacting us. You simply need to add Node8 to the Nodes collection of Node7.

Best wishes,

Good evening Victor,

I would like to add that umm, Node8 -and- Node7 are all created during runtime.

I am unable to find a 'collection' to add. I am sorry if this sounds confusing. Currently, I 'insert' nodes like this;
*parIDInTree is the Parent Node's ID in the Tree Form. This of course, doesn't work, since the added node becomes a 'sibling' node.

I also tried;
*Where... in a self explanatory manner, I try to add the node under its parent's name. However, as there are 'grandparents', this is not feasible either.

I have no idea where to 'plug in' the Collections keyword.

Sorry for all the trouble, and a sincere thanks for the prompt reply~
Yours sincerely,
H. Vi

Hello H Vi,

If you know the name of the parent node to which you to add the child node, you can find it by using RadTreeView command mechanism and FindByTextCommand in particular. You can first use the command to get a reference to the parent and then add the child node to the parent Nodes collection. Here is an example:

`FindByTextCommand cmd = ``new` `FindByTextCommand();`
`object` `parent = RadTreeView.ExecuteScalarCommand(yourTreeView.Nodes, -1, cmd, ``"Node8"``);`
`if``(parent != ``null``)`
`{`
`    ``(parent ``as` `RadTreeNode).Nodes.Add(childNode);`
`}`

Write again if you need further assistance.

All the best,
Victor
