ASPxMenuBase.SelectedItem Property

Gets or sets the selected menu item within a menu control.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v24.2.dll

Declaration

C#

public MenuItem SelectedItem { get; set; }

VB.NET

Public Property SelectedItem As MenuItem

Property Value

Type	Description
MenuItem	A MenuItem object representing the selected item.

Remarks

If the ASPxMenuBase.AllowSelectItem property is set to true, end users are allowed to select menu items via mouse clicks. A menu control (which can be either the ASPxMenu or ASPxPopupMenu) also provides the ability to select its items via code. You can use the SelectedItem property on the server side for this purpose.

Note that only one menu item can be selected within a menu control at the same time, and this item is displayed selected only if the menu’s ASPxMenuBase.ItemLinkMode property is set to the ItemLinkMode.ContentBounds value.

If none of the items is selected within a menu control or selecting is prohibited, the SelectedItem property returns null (Nothing in Visual Basic).

The selected state of an individual menu item can be specified by its MenuItem.Selected property.

Example

The code sample below demonstrates how to populate an ASPxMenu control with items manually, in unbound mode. The image below shows the result.

C#

protected void Page_Load(object sender, EventArgs e)
{
     if (!IsPostBack) {
          CreateMenu();
     }
}

//Create Menu initial structure. 
void CreateMenu() {
     string[] Items = { "Home", "News", "Products", "Client Center" };
     foreach (string ItemText in Items) {
          MyMenu.Items.Add(ItemText);
     }
     MyMenu.Items.FindByText("News").Items.Add("Subscriptions");
     MenuItem[] ProductsItems = { 
          new MenuItem("Downloads"), 
          new MenuItem("Support"), 
          new MenuItem("Order") 
     };
     MyMenu.Items.FindByText("Products").Items.Add(ProductsItems);
}

//Add a new item
protected void btnAddItem_Click(object sender, EventArgs e) {
     if ((MyMenu.SelectedItem != null) && (tbItemName.Text != "")) {
          MyMenu.SelectedItem.Items.Add(tbItemName.Text);
     }
} 

VB.NET

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
     If (Not IsPostBack) Then
          CreateMenu()
     End If
End Sub

'Create Menu initial structure. 
Private Sub CreateMenu()
     Dim Items() As String = { "Home", "News", "Products", "Client Center" }
     For Each ItemText As String In Items
          MyMenu.Items.Add(ItemText)
     Next ItemText
     MyMenu.Items.FindByText("News").Items.Add("Subscriptions")
     Dim ProductsItems() As MenuItem = { New MenuItem("Downloads"), New MenuItem("Support"), New MenuItem("Order") }
     MyMenu.Items.FindByText("Products").Items.Add(ProductsItems)
End Sub

'Add a new item
Protected Sub btnAddItem_Click(ByVal sender As Object, ByVal e As EventArgs)
     If (MyMenu.SelectedItem IsNot Nothing) AndAlso (tbItemName.Text <> "") Then
          MyMenu.SelectedItem.Items.Add(tbItemName.Text)
     End If
End Sub
