Solution:

You can Display a confirmation dialog, using simple yes/no dialog, check following code for same

        //Code that confirms weather you want to delete node
            DialogResult dialogResult = MessageBox.Show("Do you want to delete this node?", "Confirmation", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
            if (dialogResult == DialogResult.No)
            {
                return false;
            }
            else
            {
                //proceed deleting node
            }
