RowDefinitions Class

If table layout mode is enabled for a group, you can use the OptionsTableLayoutGroup.RowDefinitions collection to access table rows (this property is accessible from the LayoutGroup.OptionsTableLayoutGroup property). Members of this collection allow you to add, remove, access individual rows and perform other common collection management tasks.
