[Gelöst] Probleme mit ControlPaint.DrawBorder zwischen Form und eigenem Control

beantworten | zitieren | melden

Ich habe ein Control erstellt in welchem mit Rectangles rumgemalt wird. Das Steuerelement funktioniert soweit auch und wird bei jedem FormBorderStyle richtig angezeigt.

ABER, wenn ich um mein Form ein Rahmen haben möchte, dann mach ich das mit DrawBorder in der Form1_Paint. Und genau dann wird um mein Control der selbe Rahmen gezeichnet - was echt unschön ist.

Hat jemand eine Idee wie ich das verhindern kann ?

Ok, sorry hab des Rätsels Lösung,

In Form1_Paint hab ich DrawBorder mit e.ClipRectangle aufgerufen. Besser ist wohl für den 2 Parameter 'ClientRectangle')
