ButtonKlick???

[Mannzel]

Moin, Moin.
Ich brauche ein bischen Hilfe.
Wenn Form1 startet, ist btnPanel2 oben und btnPanel3 unten.
So soll es auch sein. Und wenn ich auf den Button "Panel3" klicke
geht dieser nach oben. Auch noch in Ordnung.
Wenn ich jetzt aber die Formgröße (Form1_Resize) verändere
geht der Button "Panel3" wieder nach unten. Das soll er nicht!!!
Erst wenn ich wieder auf Button "Panel2" klicke soll Button "Panel3" nach unten springen.

Kann mir jemand helfen.

MfG
Andreas

Na vielleicht, weil bei dir Resize-Ereigniss des Form auf btnPanel2_Click zeigt und nicht auf Form1_Resize...
