Examples

The following code example demonstrates using the GetOptionValue method to query for the value of the GridSize option.

// Obtains and shows the size of the standard design-mode grid square.
System::Drawing::Size size =  *dynamic_cast<System::Drawing::Size^>(designerOptionService->GetOptionValue( "WindowsFormsDesigner\\General", "GridSize" ));

// Obtains and shows the size of the standard design-mode grid square.
Size size = (Size)designerOptionService.GetOptionValue("WindowsFormsDesigner\\General", "GridSize");

' Obtains and shows the size of the standard design-mode grid square.
Dim size As Size = CType(designerOptionService.GetOptionValue("WindowsFormsDesigner\General", "GridSize"), Size)

Remarks

The pageName parameter should consist of "WindowsFormsDesigner\CategoryName", where CategoryName is an options category name without any white space characters. The category name is typically "General". Therefore, you can access the "General" designer options category with the English page name "WindowsFormsDesigner\General".

Note

The page and value names are always expected in English. Therefore, the following table is provided to help you access the options you want.
