Quick Start

Basic Navigation Drawer

using Syncfusion.Windows.Forms.Tools;

// Create NavigationDrawer instance
NavigationDrawer navigationDrawer1 = new NavigationDrawer();
this.Controls.Add(navigationDrawer1);

// Set drawer dimensions
navigationDrawer1.DrawerWidth = this.Width / 4;
navigationDrawer1.DrawerHeight = this.Height;

// Set position and transition
navigationDrawer1.Position = SlidePosition.Left;
navigationDrawer1.Transition = Transition.SlideOnTop;

// Add header
DrawerHeader drawerHeader1 = new DrawerHeader();
drawerHeader1.Text = "Menu";
navigationDrawer1.Items.Add(drawerHeader1);

// Add menu items
DrawerMenuItem menuItem1 = new DrawerMenuItem();
menuItem1.Text = "Home";
menuItem1.Image = Image.FromFile(@"home.png");

DrawerMenuItem menuItem2 = new DrawerMenuItem();
menuItem2.Text = "Settings";
menuItem2.Image = Image.FromFile(@"settings.png");

navigationDrawer1.Items.Add(menuItem1);
navigationDrawer1.Items.Add(menuItem2);

// Add content to ContentView
RichTextBox richTextBox = new RichTextBox();
richTextBox.Text = "Main content area";
navigationDrawer1.ContentViewContainer.Controls.Add(richTextBox);

Common Patterns

Pattern 1: Left Slide Panel with Push Transition

// Create drawer that pushes content when opened
NavigationDrawer drawer = new NavigationDrawer();
drawer.Position = SlidePosition.Left;
drawer.Transition = Transition.Push;
drawer.DrawerWidth = 250;
drawer.DrawerHeight = this.Height;
drawer.AnimationDuration = 150; // milliseconds

this.Controls.Add(drawer);

Pattern 2: Toggle Drawer with Button Click

// Toggle drawer visibility on button click
private void hamburgerButton_Click(object sender, EventArgs e)
{
    navigationDrawer1.ToggleDrawer();
}

Pattern 3: Themed Drawer with Custom Colors

// Apply Office 2016 theme with custom item colors
navigationDrawer1.Style = NavigationDrawerStyle.Office2016Colorful;

// Customize menu item colors
drawerMenuItem1.DefaultColor = System.Drawing.Color.LightBlue;
drawerMenuItem1.HoverColor = System.Drawing.Color.SkyBlue;
drawerMenuItem1.BackColor = System.Drawing.Color.LightBlue;

Pattern 4: Handle Drawer Events

// Subscribe to drawer events
navigationDrawer1.Opening += NavigationDrawer1_Opening;
navigationDrawer1.Opened += NavigationDrawer1_Opened;
navigationDrawer1.Closing += NavigationDrawer1_Closing;
navigationDrawer1.Closed += NavigationDrawer1_Closed;

private void NavigationDrawer1_Opening(object sender, OpeningEventArgs e)
{
    // Logic when drawer starts opening
    Console.WriteLine("Drawer is opening...");
}

private void NavigationDrawer1_Opened(object sender, EventArgs e)
{
    // Logic when drawer is fully open
    Console.WriteLine("Drawer opened");
}

private void NavigationDrawer1_Closing(object sender, CancelEventArgs e)
{
    // Can cancel closing if needed
    // e.Cancel = true;
    Console.WriteLine("Drawer is closing...");
}

private void NavigationDrawer1_Closed(object sender, EventArgs e)
{
    // Logic when drawer is fully closed
    Console.WriteLine("Drawer closed");
}

Pattern 5: Right-Side Drawer with Reveal Transition

// Create drawer that reveals from behind content
NavigationDrawer drawer = new NavigationDrawer();
drawer.Position = SlidePosition.Right;
drawer.Transition = Transition.Reveal;
drawer.DrawerWidth = 300;
drawer.AnimationDuration = 200;

// Add items
DrawerHeader header = new DrawerHeader { Text = "Options" };
drawer.Items.Add(header);

string[] menuItems = { "Profile", "Settings", "Notifications", "Help" };
foreach (string item in menuItems)
{
    DrawerMenuItem menuItem = new DrawerMenuItem { Text = item };
    drawer.Items.Add(menuItem);
}

this.Controls.Add(drawer);
