Remarks

The ForEachVisibleElement method iterates through visible elements and invokes the specified action for them. The following elements are regarded as invisible:

• Elements whose AccordionControlElementBase.Visible property is set to false.
• Elements that reside within collapsed groups (see AccordionControlElementBase.Expanded).

The following code shows how you can perform an action on visible elements:

C#

accordionControl1.ForEachVisibleElement((el) => {
    //Do some action
    //Toggle visibility for Items
    if (el.Style == DevExpress.XtraBars.Navigation.ElementStyle.Item) {
        el.Visible = !el.Visible;
    }
});

VB.NET

AccordionControl1.ForEachVisibleElement(Sub(el)
                                     'Do some action
                                     'Toggle visibility for Items
                                     If el.Style = DevExpress.XtraBars.Navigation.ElementStyle.Item Then
                                         el.Visible = Not el.Visible
                                     End If
                                 End Sub)
