c# - The visible property of a Label act as read only -


i have label within user control:

<asp:label runat="server" id="lblremainingplacesmessage" visible="false" />

i want setup visibility true:

protected void page_load(object sender, eventargs e) {     lblremainingplacesmessage.visible = true; }

however, label still hidden.

what's puzzling me, property can't changed, in immediate window, or debugger local watch:

(immediate window)

lblremainingplacesmessage.visible false lblremainingplacesmessage.visible = true true lblremainingplacesmessage.visible false

what can explain visible property can't changed?

i have no exception. noop operation...

my app has viewstate enabled. of all, have other label in page, works perfectly!

don't know if matter, dynamically instantiate user control within owner page using:

    protected override void createchildcontrols()     {         m_visualcontrol = (myusercontrol)page.loadcontrol(_ascxpath);         controls.add(m_visualcontrol);     }

the app uses asp.net webforms .net 3.5 sp1, , use visual studio 2012 premium.

yuriy galanter's comment put me on right track.

simply, immediate parent not visible. , suppose visible property of control combines control ancestors visibility.

sometimes simple problem have simple resolution :)

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
