Ejemplos

En el ejemplo siguiente, se pasa un elemento raíz a una función que devuelve una colección de AutomationElement objetos descendientes de la raíz y satisface un conjunto de condiciones de propiedad. En este ejemplo se recuperan los AutomationElementvalores que admiten TablePattern y donde RowOrColumnMajorProperty es Indeterminate o ColumnMajor.
