which approach has better maintainablility , extendability? where limitations/restrictions each approach? put datatype inside viewmodel or put datatype/control type in view? viewmodel [datatype(datatype.multilinetext)] public string longdescription { get; set; } or view @html.textareafor(m => m.longdescription) as far maintainability concerned, defining in view model best. given example suppose had in our vm: [datatype(datatype.multilinetext)] public string longdescription { get; set; } and in our view: @html.editorfor(m => m.longdescription); now lets requirements have changed , simple string no longer cuts longdescription, created special customrichtextformat class store it. change vm following: public customrichtextformat longdescription { get; set; } you can create editortemplate called customrichtextformat.cshtml , put in editortemplates folder in view folder, , since used @html.editorfor(m => m.longdescription); in origina...
