MenuStrip
Drag a MenuStrip from the Toolbox onto your form. Click the strip to type menu items. Each item generates a Click event when double-clicked. Set ShortcutKeys to add keyboard shortcuts.
File menu handler
MenuDemo.cs
private void openToolStripMenuItem_Click(object sender, EventArgs e)
{
using var dlg = new OpenFileDialog
{
Filter = "Text files|*.txt|All files|*.*",
Title = "Open a text file"
};
if (dlg.ShowDialog() == DialogResult.OK)
{
string content = File.ReadAllText(dlg.FileName);
txtEditor.Text = content;
this.Text = Path.GetFileName(dlg.FileName);
}
}ToolStrip & StatusStrip
A ToolStrip hosts buttons, combo boxes, and separators. A StatusStrip shows status information at the bottom of the form using ToolStripStatusLabel items.
ColorDialog & FontDialog
Use ColorDialog to let users pick a colour and FontDialog to pick a font.
