Açıklamalar
Numaralandırma, RepeatDirection liste denetiminin öğelerinin görüntülenebildiği farklı yönleri temsil eder.
Not
Görüntülenen sütun sayısı her zaman liste denetiminin RepeatColumns özelliği tarafından belirlenir.
Yatay, liste denetiminin öğelerinin, tüm öğeler işlenene kadar soldan sağa, sonra yukarıdan aşağıya yüklenen satırlarda görüntüleneceğini belirtir. Örneğin, liste denetiminin RepeatColumns özelliği üç olarak ayarlanırsa, liste denetiminin öğeleri üç sütunda görüntülenir.
| 1 | 2 | 3 |
| 4 | 5 | 6 |
| 7 | 8 |
Dikey, liste denetiminin öğelerinin yukarıdan aşağıya, ardından tüm öğeler işlenene kadar soldan sağa yüklenen sütunlarda görüntüleneceğini belirtir. Örneğin, liste denetiminin RepeatColumns özelliği üç olarak ayarlanırsa, liste denetiminin öğeleri üç öğenin satırlarında görüntülenir.
| 1 | 4 | 7 |
| 2 | 5 | 8 |
| 3 | 6 |
