//Hooks event for a particular RadialMenuItem and triggers event for the RadialMenuItem1.

foreach (Control item in this.radialMenu1.Controls)
{
    if (item is RadialMenuItem)
        item.Click += new EventHandler(item_Click);
}
//Event is triggered when the next level of RadialMenu is opened.
this.radialMenu1.NextLevelOpening += new Syncfusion.Windows.Forms.Tools.NextMenuLevelOpening(this.radialMenu1_NextLevelOpening);
void radialMenuItem1_Click(object sender, EventArgs e)
{
    //This event is triggered when RadialMenuItem1 is clicked.
    MessageBox.Show("RadialMenuItem1 is Clicked");

    MessageBox.Show((sender as RadialMenuItem).Text + " Clicked");
}
