unexpected "{" after # in razor code in mvc4 - asp.net-mvc-4

Question

I am getting below error in render partial in razor code, Unexpected "{" after "#" character. Once inside the body of a code block (#if {}, #{}, etc.) you do not need to use "#{" to switch to code.
#if (Model.Count() > 0)
{
<div id="mReserveForTodayPartial">
#{Html.Partial("UpdateReserveForToday.mobile");}
</div>
}
kindly help..!

Answer 1

Html.Partial() return MvcHtmlString so you have to do like this:
#Html.Partial("UpdateReserveForToday")
in Html.RenderPartial() case it writes to the output stream and that's why it's return type is void, so when using Html.RenderPartial() you have to do this:
#{
Html.RenderPartial("UpdateReserveForToday");
}

Answer 2

try this code:
#{ List<SelectListItem> listItems = new List<SelectListItem>();
foreach (var item in ViewData["Subcategory"] as IEnumerable<ApplicationOneStoreForEstore.Models.tblsubcategory>) {
listItems.Add(new SelectListItem {
Text = item.subcategory_name,
Value = Convert.ToString(item.subcategory_id)
});
}
}
If you have to bind DropDownList then You have to placed this code before Html.BeginForm(..)

Answer 3

Below code should resolve this issue.
#if (Model.Count() > 0)
{
<div id="mReserveForTodayPartial">
Html.Partial("UpdateReserveForToday.mobile");
</div>
}
As Razor view engine can parse the code if the statements are available with in "#{ }", So in your code "#{}" is present at "If" statement so its not required to specify again.
