How do I search for a TreeNodeAdv in the TreeViewAdv ?

Platform: WinForms |
Control: TreeViewAdv |

The best way to search a TreeViewAdv is by using a simple recursive function that will iterate through the TreeViewAdv's Nodes collection.

C#

private TreeNodeAdv Search(TreeNodeAdv tna){

if (tna.Text == text) {

return node;

}

//Checks whether the node contains child node or not. If yes, foreach statement will iterate through all sibiling nodes of this node.

if(tna.HasChildren){

foreach(TreeNodeAdv tnac in tna.Nodes)

Search(tnac);

}

if(tna.NextNode !=null)

{

Search(tna.NextNode);

}

return null;

}

VB

Public Function Search(tna As TreeNodeAdv ) As TreeNodeADv

If tna.Text == text Then Return node;

'Checks whether the node contains child node or not. If yes, foreach statement will iterate through all sibiling nodes of this node.

If tna.HasChildren

Dim tnac as TreeNodeAdv

For Each(TreeNodeAdv tnac in tna.Nodes)

Search(tnac)

Next

If Not tna.NextNode =Nothing Then Search(tna.NextNode);

Return Nothing

End Function
