The RadMenuContentItem is a container control that allows you to build up custom menu items from other controls. You can assign any RadElement based control to the ContentElement property of a RadMenuContentItem. The example below demonstrates dynamically creating two main menu items that contain RadTextBox and RadButton elements. When the button is clicked a message box displays the text.

void Form1_Load(object sender, EventArgs e)
{
RadTextBoxElement textBox = new RadTextBoxElement();
textBox.Text = "Enter text here";
textBox.MinSize = new Size(100, 0);
radMenu1.Items.Add(textBox);
RadButtonElement button = new RadButtonElement();
button.Text = "OK";
button.MaxSize = new Size(0, 20);
button.Click += new EventHandler(button_Click);
radMenu1.Items.Add(button);
}
void button_Click(object sender, EventArgs e)
{
RadTextBoxElement textBox = radMenu1.Items[1] as RadTextBoxElement;
MessageBox.Show("Text is: " + textBox.Text);
