In TreeViewAdv, you can filter TreeNodeAdv based on its Tag value. The following code example demonstrates the same.
C# Code Snippet:
List<TreeNodeAdv> nodes;
//To search all nodes
nodes = treeViewAdv1.SearchTree().Where(n => n.Tag == "Search node").ToList();
public static class SOExtension
{
public static IEnumerable<TreeNodeAdv> SearchTree(this TreeViewAdv treeView)
{
return SearchTree(treeView.Nodes);
}
public static IEnumerable<TreeNodeAdv> SearchTree(this TreeNodeAdvCollection coll)
{
return coll.Cast<TreeNodeAdv>().Concat(coll.Cast<TreeNodeAdv>().SelectMany(x => SearchTree(x.Nodes)));
}
}VB Code Snippet:
Private nodes As List(Of TreeNodeAdv)
'To search all nodes
nodes = treeViewAdv1.FlattenTree().Where(Function(n) n.Tag = "Search node").ToList()
Public Module SOExtension
<System.Runtime.CompilerServices.Extension()> _
Public Function SearchTree(ByVal treeView As TreeViewAdv) As IEnumerable(Of TreeNodeAdv)
Return SearchTree(treeView.Nodes)
End Function
<System.Runtime.CompilerServices.Extension()> _
Public Function SearchTree(ByVal coll As TreeNodeAdvCollection) As IEnumerable(Of TreeNodeAdv)
Return coll.Cast(Of TreeNodeAdv)().Concat(coll.Cast(Of TreeNodeAdv)().SelectMany(Function(x) SearchTree(x.Nodes)))
End Function
End Module
The following screenshot illustrates the search TreeNodeAdv by using its Tag value.
