C# Hinzufügen von UserControl zu TabControl dann Rendern mit SharpDX

Question

wie im Titel gesagt, ich füge ein UserControl zu einem TabControl. Das funktioniert einfach gut. Aber wenn ich mit SharpDX.Direct3D11 auf dieses UserControl rendere, verschwindet die Registerkarte.

Ich habe versucht, es so einfach wie möglich zu halten, damit die Steuerung funktioniert. Der Code, den ich für das Steuerelement verwende, stammt aus den bereitgestellten Beispielen. Das Beispiel "MiniCube" funktioniert, wenn ich es in der bereitgestellten Lösung erstelle.

Hier ist der Code i machen verwenden:

using SDX = SharpDX;

using Buffer = SharpDX.Direct3D11.Buffer; 
using Device = SharpDX.Direct3D11.Device;

ich sonst keine Ausnahmen oder etwas nicht bekommen. Der Tab verschwindet einfach und das ist alles. Soweit ich feststellen konnte, dass der Code läuft, habe ich eine Debug-Session eingecheckt.

Die SharpDXRenderManager ist nur aus dem Usercontrol selbst, hier der Code genannt:

public partial class Planner : UserControl 
{ 
     private SharpDXRenderManager renderManager; 

     public Planner() 
     { 
      InitializeComponent(); 

      renderManager = new SharpDXRenderManager(this); 
      renderManager.Render(); 
     } 
} 

Answer 1

Das Problem ist, dass ich das machen Prozess direkt nach der Initialisierung begonnen haben. Ich löste es, indem ich die Methode Render() im OnLoad (EventArgs e) Event anrief.
