Description

In the following example, we will demonstrate how you can add a vertical separator in the RadMenu control.

Solution

To add a vertical separator to a RadMenu, use the RadMenuSeparatorItem class. You can customize the separator's orientation. The following code snippet demonstrates how to insert a vertical separator item between RadMenuItems upon form load. Ensure to adjust the index in the Items.Insert method according to where you want to place the separator in your menu.

C#

private void Form1_Load(object sender, EventArgs e)
{
    var menuSeparatorItem = new Telerik.WinControls.UI.RadMenuSeparatorItem();

    menuSeparatorItem.Name = "myPanel_Menu_Sep1";
    menuSeparatorItem.SeparatorOrientation = Telerik.WinControls.SepOrientation.Vertical;
    menuSeparatorItem.BackColor = Color.Red;
    menuSeparatorItem.ShouldPaint = true;
    menuSeparatorItem.TextVisibility = Telerik.WinControls.ElementVisibility.Visible;
    radMenu1.Items.Insert(1, menuSeparatorItem);
}

This approach allows you to dynamically add a vertical separator to your RadMenu, enhancing the menu's visual structure and organization.
