Hi,

I have this:

But i get the errors at line 7:
->The best overloaded method match for 'System.Windows.Forms.TreeNodeCollection.Add(string, string)' has some invalid arguments
->Argument 1: cannot convert from 'System.Windows.Forms.TreeNode' to 'string'

Who can help me?

P

string NewText = "";
            if (InputBox.Show("New Folder", "Folder Name", ref NewText, validation) == DialogResult.OK)
            {
                TreeNode n = new TreeNode();
               // MessageBox.Show(NewText);
                TreeNode n2 = tvNotes.SelectedNode;
                n.Nodes.Add(n2, NewText);
            }

Open in new window

mkobrin

Try
n.Nodes.Add(n2.ToString(), NewText);
or
n.Nodes.Add(Convert.ToString(n2), NewText);
or
n.Nodes.Add(n2.Text, NewText);

I have this now, its error free but it does not work:

string NewText = "";
if (InputBox.Show("New Folder", "Folder Name", ref NewText, validation) == DialogResult.OK)
{
TreeNode n = new TreeNode();
TreeNode n2 = tvNotes.SelectedNode;
n.Nodes.Add(n2.Text, NewText);
}

Do you know perhaps why?
