كيفية القيام بما يلي: ربط وارساء عناصر التحكم التابعة في عنصر تحكم FlowLayoutPanel
يدعم عنصر تحكم FlowLayoutPanel خصائص Anchor و Dock في عنصر تحكم التابع (الفرع) الخاص به.
لربط وارساء عناصر التحكم التابعة في عنصر تحكم FlowLayoutPanel
قم بإنشاء عنصر تحكم FlowLayoutPanel في النموذج الخاص بك.
قم بتعيين خاصية Width التابعة لعنصر تحكم FlowLayoutPanel إلى 300, و عيين FlowDirection الخاصة به إلى TopDown.
قم بإنشاء عنصري تحكم Button, وضعهما في عنصر تحكم FlowLayoutPanel.
عيين Width الخاص بالزر الأول إلى 200.
عيين خاصية Dock الخاصة بالزر الثاني إلى Fill.
ملاحظة
ويفترض الزر الثاني نفس عرض الزر الأول. لا يتمدد عبر عرض عنصر تحكم FlowLayoutPanel.
عيين خاصية Dock الخاصة بالزر الثاني إلى None. وهذا يؤدي إلى افتراض الزر الثاني لعرضه الأصلي.
تعيين خاصية Anchor الخاصة بالزر الثاني إلى اليسار, اليمين.
هام
ويفترض الزر الثاني نفس عرض الزر الأول. لا يتمدد عبر عرض عنصر تحكم FlowLayoutPanel. هذه هي القاعدة العامة في الترسيخ و الإرساء لدى عنصر تحكم FlowLayoutPanel : للحصول على إرشادات بانسياب عمودي, يحسب عنصر تحكم FlowLayoutPanel عرض العمود الضمني من أعرض فرع عنصر التحكم في العمود. يتم محاذاة أو تمديد كل عناصر التحكم الأخرى في هذا العمود مع خصائص Anchor أو Dock لاحتواء هذا العمود الضمني. يعمل السلوك بطريقة مشابهة لإتجاه التدفق الأفقي. يحسب عنصر تحكم FlowLayoutPanel ارتفاع الصف الضمني من أطول فرع عنصر تحكم في الصف, ثم يتم محاذاة أو تحجيم كل أفرع عناصر التحكم المرتبطة والراسية في هذا الصف ليتم احتواء الصف المقدر.
مثال
يبين الرسم التوضيحي التالي الأزرار الأربعة المرتبطة بالنسبة للزر الأزرق في FlowLayoutPanel. FlowDirection هو LeftToRight.
يبين الرسم التوضيحي التالي الأزرار الأربعة المرتبطة بالنسبة للزر الأزرق في FlowLayoutPanel. FlowDirection هو TopDown.
يوضح مثال التعليمات البرمجية التالي قيم خاصية Anchor المختلفة لعنصر تحكم Button الموجود في عنصر تحكم FlowLayoutPanel.
