  treeview - how to get the selected node

  Jan 05, 2013 01:16 PM|LINK

  Hi folks,

  I have a treeview. The user should select one o its node (a folder) and I need to read its path, because the user will send a file to be stored in this folder.

  How do I read the selected node of a treeview?

   

   

  TIA

  It's very simple. You can use the SelectedNodeChanged event of TreeView:

  protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e) {
              string valNode = TreeView1.SelectedValue;
              TreeNode tn = TreeView1.SelectedNode;
          }

  With SelectedValue property, you can read the current selected value. With the SelectedNode property can give you an easy access to Text, Value and ValuePath of the selected node. This last property (ValuePath) is an "union" of all path. For example, with this treeview structure

  • A
    • 1A
    • 2A
  • B
    • 1B

  if you select "2A", ValuePath will be "A/2A". Note you can set PathSeparator (default is '/') as you prefer.
