Gets or sets a value that specifies the group's initial visibility state on the client.
true to make a group initially displayed on the client; false to render the group into the control, but make it initially hidden on the client side.
Use the ClientVisible property to define a group's initial visibility state. The group's visibility can then be dynamically changed on the client side using the ASPxClientNavBarGroup.SetVisible method.
If a group's server NavBarGroup.Visible property is set to false, the group is not rendered into the web page at all, so it can't be manipulated on the client side.
