Window controls
This property is valid for .NET Web Forms applications only when the PBThemeManager global property is set to true. The global property allows the Theme Manager icon to display on all window forms in your Web Forms applications. The Theme Manager icon allows users to change the display of controls in your application.
By default, the HasThemeManager property is set to true and the PBThemeManager is set to false. When you change the PBThemeManager global property to true, all window forms display the Theme Manager icon unless you set the HasThemeManager for a particular window to false.
Icon display in MDI Web Forms applications In MDI applications, manager icons display on the frame window. To hide the Theme Manager icon when the PBThemeManager global property is set to true, you must set the HasThemeManager property of both the frame and the active sheet to false.
You must surround the HasThemeManager property in a conditional compilation code block for Web Forms applications:
#if defined PBWEBFORM then
w_mywindow.HasThemeManager = false
#end if
