How to select or find a TTreeView node by caption

Answer:

Solve 1:
1   
2   function GetNodeByCaption(NodeCaption: string): TTreeNode;
3   var
4     X: Integer;
5   begin
6     Result := nil;
7     for X := 0 to TreeView1.Items.Count - 1 do
8     begin
9       if (TreeView1.Items[X].Caption = NodeCaption) then
10        Result := TreeView1.Items[X];
11      Break;
12    end;
13  end;



Solve 2:

Returns a node based on the text property. Set AVisible to show the new node:
14  
15  function GetNodeByText(ATree: TTreeView; AValue: string;
16    AVisible: Boolean): TTreeNode;
17  var
18    Node: TTreeNode;
19  begin
20    Result := nil;
21    if ATree.Count = 0 then
22      Exit;
23    Node := ATree.Items[0];
24    while Node <> nil do
25    begin
26      if UpperCase(Node.Text) = AValue then
27      begin
28        Result := Node;
29        if AVisible then
30          Result.MakeVisible;
31        Break;
32      end;
33      Node := Node.GetNext;
34    end;
35  end;
