How to add a child node to a specific node in treeview?
Say i have "Item1" in treeview already, How do i add "SubItem1" to "Item1" as it's child node?

View 2 RepliesIs there any way to use selectnode with the attribute having both single and double quotes? If we are having single quote in the attribute we can use like below,
nodeList = root.SelectNodes("//book[contains(title,""'attribute'"")]")
If we are having double quotes we can use,
nodeList = root.SelectNodes("//book[contains(title,'"""attribute"""')]")
how can I use an attribute ['attribute"] having both single and quotes in SelectNodes.
how I can shorten this and still get the same result (Wildcards maybe?)?
Dim NodeList As XmlNodeList
NodeList = NodeItem.SelectNodes("/Resultset/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group/Group[@name=""GroupPos""]/Field[@name=""S_TotalValue""]")
