my stored procedure is changing the no. of columns(fields) dynamically according to the parameter passed to it through dropdownlist.... As I am new in MVC Please help in same... This error is coming after retuning the result from GetList(String MatchTypeName)..... Error: The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[System.Object]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[LearningMVC.Controllers.MyController]'. Problem is with cshtml code @model IEnumerable(LearningMVC.User)

public ActionResult Index(string MatchTypeName)

foreach (MatchTypeMaster MatchType in db.MatchTypeMasters)
SelectListItem selectMatchTypes = new SelectListItem
Text = MatchType.MatchTypeName,
Value = MatchType.MatchTypeID,


ViewBag.MatchTypeName = selectMatchTypeList;

if (string.IsNullOrEmpty(MatchTypeName))
MatchTypeName = "XYZ";
var bugedlist = GetList(MatchTypeName);
return View(bugedlist);
var GridFill = GetList(MatchTypeName);
return View(GridFill);

return View();


public List GetList(String MatchTypeName)
//var modelList = new List();
var result = new List();

using (SqlConnection conn = new SqlConnection(@"Server= server_name; Uid=xyz;pwd=pass; database=db_name"))


SqlCommand dCmd = new SqlCommand("SP_WEBBASEDREPorTS", conn);

dCmd.CommandType = CommandType.StoredProcedure;

dCmd.Parameters.Add(new SqlParameter("@MatchType", MatchTypeName));

dCmd.Parameters.Add(new SqlParameter("@ModeFlag", "Batting Industry Average"));

SqlDataAdapter da = new SqlDataAdapter(dCmd);
DataSet ds = new DataSet();
DataTable table = new DataTable();


foreach (DataRow row in table.Rows)
var obj = (IDictionary<string,>)new ExpandoObject();
foreach (DataColumn col in table.Columns)
obj.Add(col.ColumnName, row[col.ColumnName]);


return result;

CSHTML Code is:

@using GridMvc.Html;

@model IEnumerable(LearningMVC.User)
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";

@Html.ActionLink("Create New", "Create")

@using (@Html.BeginForm("Index", "My", FormMethod.Get))

@Html.DropDownList("MatchTypeName", "Select All");
<input type="submit" value="Filter" />

Please format the question properly

1 solution

You should change the type of collection you return in the actionresult to
IEnumerable<user> or List<user></user></user>

Hope this helps
