While trying to dynamicaly load master page:
RCFontSize fontSize = GetFontSize();
switch (fontSize)
{
case RCFontSize.Large:
Page.Master.MasterPageFile = "~/MasterPages/Admin/MainLayout_T_Large.master";
break;
case RCFontSize.Medium:
Page.Master.MasterPageFile = "~/MasterPages/Admin/MainLayout_T_Medium.master";
break;
case RCFontSize.Small:
Page.Master.MasterPageFile = "~/MasterPages/Admin/MainLayout_T_Small.master";
break;
default:
Page.Master.MasterPageFile = "~/MasterPages/Admin/MainLayout_T_Medium.master";
break;
I have experienced following error:
MasterPage cannot be applied to this page because the control collection is read-only.
If the page contains code blocks, make sure they are placed inside content controls (i.e. <asp:Content runat=server />)
The page loading is an empty page which just assign src property of the frames on master pages which is inhereted from class to expose frame src propetry.
I hope I was clear enough,
Any help is greatly appreciated.
P.S. There is no code blocks on loading page. just two events on codebehind page preinit and pageload which contain the code.
