The document describes how to use the 'contextmenustrip' control in Windows Forms applications, detailing the addition of menu items and changing properties. It highlights the advantages of using a 'richtextbox' for text formatting, including options for colors and fonts, compared to a standard textbox. Two example code snippets are provided to illustrate how to change the background color and text color dynamically.

4. Select the “ContextMenuStrip” control and start adding the name of menus, for example I added menus like Background,
foreground and then add form, button submenu to Background menu .

5. After adding the name of the menu on you application, right-click on the Windows Forms application and go to the
properties.
Select "ContextMenuStrip" and change it to ContextMenuStrip1 from (none).

6. run the project and right-click on the form, the Context Menu will appear on the form as shown in the

7. • RichTextBox has many formatting options.
It applies colors, background colors,
multiple fonts, and margins to the text.
• It adds more complexity than the regular TextBox.
• But the RichTextBox provides needed features to
programs.

private void button1_Click(object sender, EventArgs e)
{
richTextBox1.SelectionBackColor = Color.Coral;
richTextBox1.AppendText(this.textBox1.Text);
}
private void button1_Click(object sender, EventArgs e)
{
colorDialog1.ShowDialog();
richTextBox1.SelectionColor = colorDialog1.Color;
richTextBox1.AppendText(" hi");
