# RadMenuItem Events

Usually you will handle the events of the objects that make up a menu, not the **RadMenu** itself.

## RadMenuItem Events

The key event for the **RadMenuItem** object is the **Click** event, which is fired when the user selects the menu item or presses the associated shortcut key. If the menu item is designed to display check marks, then the **ToggleStateChanging** and **ToggleStateChanged**  events fire when a check mark is applied to or removed from the **RadMenuItem** object.

* **ToggleStateChanging:** Passes a **StateChangingEventArgs** parameter with properties for **NewValue**, **OldValue** and **Cancel**. Both **NewValue** and **OldValue** are **ToggleState** enumeration types with values *Indeterminate*, *On* and *Off*. If the **Cancel** argument is set to *true* the check-box does not change its state and the **ToggleStatedChanged** event does not fire.

#### Handling the ToggleStateChanging event

```C#
void radMenuItem2_ToggleStateChanging(object sender, StateChangingEventArgs args)
{
    if (args.NewValue == Telerik.WinControls.Enumerations.ToggleState.Indeterminate)
    {
        args.Cancel = true;
    }
}
```

```VB.NET
Private Sub radMenuItem2_ToggleStateChanging(ByVal sender As Object, ByVal args As StateChangingEventArgs)
    If args.NewValue = Telerik.WinControls.Enumerations.ToggleState.Indeterminate Then
        args.Cancel = True
    End If
End Sub
```

* **ToggleStateChanged**: This event fires when the check-box state changes between one of the **ToggleState** enumeration values of *On*, *Off* or *Indeterminate*. The **StateChangedEventaArgs** passed to this event handler contain the **ToggleState** property.

#### Handling the ToggleStateChanged event

```C#
void radMenuItem2_ToggleStateChanged(object sender, StateChangedEventArgs args)
{
    MessageBox.Show(args.ToggleState.ToString());
}
```

```VB.NET
Private Sub radMenuItem2_ToggleStateChanged(ByVal sender As Object, ByVal args As StateChangedEventArgs)
    MessageBox.Show(args.ToggleState.ToString())
End Sub
```

## RadMenuComboItem Events

For the **RadMenuComboItem**, you will probably want to work with the events of the embedded **ComboBoxElement** property. The example below uses the ComboBoxElement.**SelectedIndexChanged** event to get the currently selected combo box value.

#### Handling the SelectedIndexChanged event of RadMenuComboItem

```C#
void Form1_Load(object sender, EventArgs e)
{
    radMenuComboItem1.ComboBoxElement.SelectedIndexChanged += new Telerik.WinControls.UI.Data.PositionChangedEventHandler(ComboBoxElement_SelectedIndexChanged);
}

void ComboBoxElement_SelectedIndexChanged(object sender, EventArgs e)
{
    RadListDataItem item = (sender as RadDropDownListElement).SelectedItem as RadListDataItem;
    MessageBox.Show(item.Text);
}
```

```VB.NET
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)
    AddHandler radMenuComboItem1.ComboBoxElement.SelectedIndexChanged, AddressOf ComboBoxElement_SelectedIndexChanged
End Sub

Private Sub ComboBoxElement_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
    Dim item As RadListDataItem = TryCast((TryCast(sender, RadDropDownListElement)).SelectedItem, RadListDataItem)
    MessageBox.Show(item.Text)
End Sub
```

## RadMenuContentItem

Handle the events for the control assigned to RadMenuContentItem.**ContentElement**, not the content item itself. In the example below an event handler is attached to the **Click** event of a button.

#### Handling events for controls embedded in RadMenuContentItem

```C#
RadMenuContentItem buttonItem = new RadMenuContentItem();
RadButtonElement button = new RadButtonElement();
button.Text = "OK";
button.Click += new EventHandler(button_Click);
buttonItem.ContentElement = button;
radMenu1.Items.Add(buttonItem);
```

```VB.NET
Dim buttonItem As New RadMenuContentItem()
Dim button As New RadButtonElement()
button.Text = "OK"
AddHandler button.Click, AddressOf button_Click
buttonItem.ContentElement = button
RadMenu1.Items.Add(buttonItem)
```
