Hi

i have a treeview.
.
how can i select a special item for example "M3" or "B2" or "A1" , in runtime?!?

Try this one for size.

Code: Pascal  [Select][+][-]

1. procedure SelectNodeByText(const aTreeView:TTreeView; aNodeText:String);
2. var
3.   vNode : TTreeNode;
4.   vLastNode : TTreeNode;
5. begin
6.   for vNode in aTreeView.Items do begin
7.     if vNode.Text = aNodeText then begin
8.       vLastNode := vNode;
9.       vNode.Selected := True;
10.       if not aTreeView.MultiSelect then Break;
11.     end;
12.   end;
13.   vLastNode.Focused := True;
14. end;
15.  

No cpu suffered through the compilation of the above code and no compiler was harmed in the process of making it.

"this" is an example, based on your first post of treeview nodes with Text such as "A1" and "B2", of how to select a particular node at runtime, based on the node's text (entered via an edit control).
The example uses a procedure called SelectNode(), which takes a node text string as a parameter to  identify the node which should be selected.

To select items in a listview, as in your latest post, a similar sort of procedure could be devised, if at runtime you want to select a named item via code rather than through a user mouse click.

Not enough information. I have demonstrated everything you need to know to accomplish your task. If you do not understand something ask specific questions.
