I create a partial view and add this in "Create.chtml" in my project which will display all area from database in create page. Everything(Insert, Update,Delete) works fine but when i click on the create button without select an item from dropdownlist it generate an error.

The model item passed into the dictionary is of type 'NHPractice2.Models.Area', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[NHPractice2.Models.Area]'.


Partial View
HTML
@model IEnumerable<NHPractice2.Models.Area>
@using NHPractice2.Models

@{
    WebGrid grdArea = new WebGrid(Model, canPage: true, rowsPerPage: 10, defaultSort: "Name");
}

@grdArea.GetHtml(tableStyle: "Grid", headerStyle: "Header", alternatingRowStyle: "altRow", columns: grdArea.Columns(
    grdArea.Column("Sl No.", format: item => item.WebGrid.Rows.IndexOf(item) + 1, style: "serialCol"),
    grdArea.Column("Area", format: item => item.Name),
    grdArea.Column("City", format: item => item.CityName),
    grdArea.Column("Action", format: @<text>@Html.ActionLink("Edit", "Edit", new { id = item.ID }, new { onclick = "return confirm('Are sure wants to edit?');" }) | @Html.ActionLink("Delete", "Delete", new { id = item.ID }, new { onclick = "return confirm('Are sure wants to delete?');" })</text>)

        )
           )


Controller Code
C#
[ChildActionOnly]
public ActionResult AreaList()
{            
  IEnumerable<Area> areas = AreaRepo.ShowAreaList(1, 0, "", 0);
  return PartialView("AreaList",areas);
}


Code from Create.chtml
HTML
@Html.Action("AreaList", new List<NHPractice2.Models.Area> { new NHPractice2.Models.Area() });


What I have tried:

I tried several times to solve it but same result.

Error occurs due to model partial view and sending model to partial view.Try List like @model List<NHPractice2.Models.Area> instead of @model IEnumerable<NHPractice2.Models.Area>. Try with below steps:

In PartialView
Razor
@model List<NHPractice2.Models.Area>
@using NHPractice2.Models
 
@{
    WebGrid grdArea = new WebGrid(Model, canPage: true, rowsPerPage: 10, defaultSort: "Name");
}

In Controller
C#
[ChildActionOnly]
public ActionResult AreaList()
{            
  List<Area> areas = (AreaRepo.ShowAreaList(1, 0, "", 0)).ToList();
  return PartialView("AreaList", areas);
}

In view(to call partial view)
Razor
@Html.Action("AreaList", "ControllerName");

Thank for your response. If i use @model NHPractice2.Models.Area instead of @model IEnumerable<nhpractice2.models.area>, following error happens.

The best overloaded method match for System.Web.Helpers.WebGrid.WebGrid(System.Web.HttpContextBase, string, int, bool, bool, string, string, string, string, string, string, string)' has some invalid arguments

cannot convert from 'NHPractice2.Models.Area' to 'System.Web.HttpContextBase'
