c# - refresh panel content when modal child is shown -

i have main form panel drawn 3d scene. ok.

after create modal form go modify things in 3d scene, , wish see result straight without closing modal form, until close form, no changes in '3d' panel.

i tried this:

my3dpanel.invalidate();

with nil changes;

my3dpanel.refresh();

with panel take 'background' init color until close modal form.

how can this?

to refresh created static class this:

public static class editorhelper { public delegate void refreshbridgeeventhandler(); public static event refreshbridgeeventhandler refreshbridgeevent; public static void needtonotifyparent() { if (refreshbridgeevent != null) { refreshbridgeevent(); } } }

and main window:

public frmmain() { initializecomponent(); editorhelper.refreshbridgeevent += editorhelper_refreshbridgeevent; } void editorhelper_refreshbridgeevent() { my3dpanel.invalidate(); my3dpanel.refresh(); this.refresh(); }
