Razor Engine Issue in MVC4 - asp.net-mvc-4

Question

When I declare a text box in view page the below error will appear
The type arguments for method 'System.Web.Mvc.Html.InputExtensions.TextBoxFor<TModel,TProperty>(System.Web.Mvc.HtmlHelper<TModel>,
System.Linq.Expressions.Expression<System.Func<TModel,TProperty>>)'
cannot be inferred from the usage. Try specifying the type arguments
explicitly
even I included
<compilation debug="true" targetFramework="4.0">
<!-- ... -->
</compilation>
this in webconfig file
but the same error shows .
............
my code
#Html.TextBoxFor(x => x.Entity, new { #id = "Entityname" })
//..........
model
public string Entity { set; get; }
//.........
//..............
.cshtml page
#model BOSSNew.Models.NewQuantifierM
#{Layout = "../Shared/_Layout.cshtml";}
<div class="breadCrumbHolder">
#{Html.RenderAction("BreadCrumb", "Base", new { menulist = new string[] { "Quantifier", "New Quantifier" }, CurrentURL = new string[] { "#", "#" } });}
</div>
<div class="divContentPane">
<div class="contentPaneHead">
<span class="contentPaneTitle">Users Details </span>
</div>
<table class="ClsTable ClsPad0">
<tr class="even">
<th>#LabelHelper.GetLabel("THLentity", 3)
</th>
<td>
#Html.TextBoxFor(x => x.Entity, new { #id = "Entityname" })
<img title="" id="selectentit" style="margin: 5px" onclick="getentity('txtentity','optentity')"
alt="" src="../../../Name.Controls/Themes/Name-Theme/images/entity.png">
</td>
</tr>
</table>
</div>
//.............
Any idea ?
Any help will be appreciated

Answer 1

You haven't defined model for a view, so you can't use
x => x.Field
expression.
It should look more or less like that:
SomeView.cshtml
#model SomeModel
#{Layout = "../Shared/_Layout.cshtml";}
<div class="breadCrumbHolder">
#{Html.RenderAction("BreadCrumb", "Base", new { menulist = new string[] { "Quantifier", "New Quantifier" }, CurrentURL = new string[] { "#", "#" } });}
</div>
<div class="divContentPane">
<div class="contentPaneHead">
<span class="contentPaneTitle">Users Details </span>
</div>
<table class="ClsTable ClsPad0">
<tr class="even">
<th>#LabelHelper.GetLabel("THLentity", 3)
</th>
<td>
#Html.TextBoxFor(x => x.Entity, new { #id = "Entityname" })
<img title="" id="selectentit" style="margin: 5px" onclick="getentity('txtentity','optentity')"
alt="" src="../../../Name.Controls/Themes/Name-Theme/images/entity.png">
</td>
</tr>
</table>
</div>
SomeModel.cs
public class SomeModel
{
public string Entity { set; get; }
}
And finally in your action method...
public ActionResult SomeMethod()
{
var model = new SomeModel();
//here fill the entity field
return View(model);
}
