The server-side ButtonToggle event occurs when a toggle button is toggled, causing a postback.

The event handler function receives two arguments:

  1. The RadRibbonBar which has fired the event. This argument is of type object, but can be cast to the RadRibbonBar type.

  2. An EventArgs object with the following properties:

    • Button - the toggle button that has been toggled.

    • Group - the group of the clicked toggle button parent's group.

    • Index - the index of the clicked button in its containing group.

The following example shows how to use the properties of the event arguments:

protected void RadRibbonBar1_ButtonToggle(object sender, RibbonBarButtonToggleEventArgs e)
    string message = string.Format("ToggleButton {0} was toggled.", e.Button.Text);
    string details = string.Format("Group: {0}, Index: {1}", e.Group.Text, e.Index);

    textBox1.Text = string.Format("{0} {1}", message, details);

Protected Sub RadRibbonBar1_ButtonToggle(ByVal sender As Object, ByVal e As RibbonBarButtonToggleEventArgs)
    Dim message As String = String.Format("ToggleButton {0} was toggled.", e.Button.Text)
    Dim details As String = String.Format("Group: {0}, Index: {1}", e.Group.Text, e.Index)

    textBox1.Text = String.Format("{0} {1}", message, details)
End Sub
