Question

So in my project i would like have a nice treeview that has images.
but when i run the program the image was not shown. Any idea?
here is my code:

 while (thisreader.Read())    // i read from the database.
        {
            TreeNode tn = new TreeNode();
        tn.Text = thisreader["channel_name"].ToString();

        tn.ImageIndex = 1;
        tn.SelectedImageIndex = 1;   // i have my imagelist1 in the corresponding winform
        treeView1.Nodes.Add(tn);
        }

Answer 1

The ImageList must be assigned to the ImageList property of the TreeView as well. Simply dropping it on the form is not enough.
