Html.Hidden returns different value

I have problem, which i can't understand.

int i = Convert.ToInt32(Model.dt);
MvcHtmlString s = Html.Hidden("DishType", Convert.ToInt32(Model.dt));
MvcHtmlString ss = Html.Hidden("DishType", 4);

i = 4

s = input id="DishType" name="DishType" type="hidden" value="22"

ss = input id="DishType" name="DishType" type="hidden" value="22"

Why value is 22, if para开发者_运维技巧metr is 4 in both cases ???

this is because you passed in on wrong location

what you need to use is:

<%= Html.Hidden("name",null,new{Value = "your attributes here"}) %>
