Hi, I'm using vs2005 .net 2.0.  I need some sample code for ListView_MouseDoubleClick event. I have a left pane of a treeview control and a right pane of a Listview control that list 1 level of the children nodes of the TreeView's selected node.  I need some sample code to perform behvior like one sees in the Active Directory Users and Computers snap-in.  

I need sample code on how to get the TreeView control to select and foucs on the node that is the parent node of the child node that I juts double clicked on the listivew control.  And the TreeView control would also expand 1 level.  

Thanks.

You can try this way:
//You can put in the tag property of the list view item the node reference...
private void treeView_AfterSelect(object sender, TreeViewEventArgs e)
    {
      listView.Items.Clear();
      foreach (TreeNode node in e.Node.Nodes)
         {
                 ListViewItem li =  new ListViewItem(node.Text);
                 li.Tag = (object)node;
         }
    }

    private void listView_DoubleClick(object sender, EventArgs e)
    {
       if (listView.SelectedItems[0]!=null)
       {
              TreeNode aNode = listView.SelectedItems[0].Tag as TreeNode;
              if (aNode != null)
                      tree.SelectedNode = aNode;
       }
    }

Hope this helps.

Hi Mishu,

             TreeNode aNode = listView.SelectedItems[0].Tag as TreeNode;

Thanks.

Sorry I forgot something...
Add this  line at the after select event:
listView.Items.Add(li);

Hi Mishu,

I've added the code as follow but when I double clicked on the Listview's node, nothing happens.  Thanks.


        private void ppTree_AfterSelect(object sender, TreeViewEventArgs e)
        {

            NodeDetail.Items.Clear();
            foreach (TreeNode node in e.Node.Nodes)
            {
                ListViewItem li = new ListViewItem(node.Text);
                li.Tag = (object)node;
                NodeDetail.Items.Add(li);
            }

............


        private void NodeDetail_MouseDoubleClick(object sender, MouseEventArgs e)
        {

            if (NodeDetail.SelectedItems[0]!=null)
            {
               TreeNode aNode = NodeDetail.SelectedItems[0].Tag as TreeNode;
                  if (aNode != null)
                          ppTree.SelectedNode = aNode;
            }


        }

Replace your current method with this:

private void NodeDetail_MouseDoubleClick(object sender, MouseEventArgs e)
        {

            if (NodeDetail.SelectedItems[0]!=null)
            {
               TreeNode aNode = NodeDetail.SelectedItems[0].Tag as TreeNode;
                  if (aNode != null)
                  {
                          ppTree.SelectedNode = aNode;
                          aNode.EnsureVisible();
                          ppTree.Focus();
                  }
            }

        }

Hope it solves the problem.
Regards,
Mishu
