Using Treeview & Panel control in Windows Form

This is a sample article, as I have seen many asking regarding how to work with panels I will just show you a sample.


This is a sample article, as I have seen many asking regarding how to work with panels I will just show you a sample

In this article I would like to share with you how you can load a panel corresponding to the selected node from a tree view.

I have done this by using tree view so that it is easy to understand and later you will know how to load user controls to be displayed in a panel. Only one Panel was used and was used in a clear fashion; you can add as many controls as you can and can display for a basic tree view; I have used just a label. I have seen many of them asking that they are using 3 Panels it is a bit tricky to hide the 2 remaining panels and showing a panel. So better go through the example so that you can know how to use a single panel instead of having multiple panels.

Controls Used

Tree view, Panel, User controls.

First, place a tree view and a Panel on the form.

Create the required user controls that you need to be loaded inside the panel.

Sample Forms:

If User control1 selected

If the latter is selected

If root was selected after User controls

Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace Samplapp
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {
            if (treeView1.SelectedNode.Text == "Usercontrol1")
            {
                panel1.Controls.Clear();
                panel1.Visible = true;
                UserControl1 usr1 = new UserControl1();
                usr1.Show();
                panel1.Controls.Add(usr1); 
            }
            if (treeView1.SelectedNode.Text == "Usercontrol2")
            {
                panel1.Controls.Clear();
                panel1.Visible = true;
                UserControl2 usr2 = new UserControl2();
                usr2.Show();
                panel1.Controls.Add(usr2);
            }
            if (treeView1.SelectedNode.Text == "Root")
            {
                panel1.Controls.Clear();
                panel1.Visible = false;
            }
        }
    }
}

Happy Coding!
