Hello, Jason

Thank you for post with attachment.

I can found the problem.

I have not link the related javascript file and css file for iggrid  of infragistics.

After include these files the grid was successfully created.

Also I want to create a grid with dynamic columns that comes from database table specific column values. Column values depends on difference table column values.

And successfully create dynamic column grid but faced an error at run time in controller when add new records using iggrid.

View:

@model MessManagement.Models.GridVirtualizationModel
@using Infragistics.Web.Mvc;
@using MessManagement.Models;
@using System.Web;

@{
    ViewBag.Title = "MealInfo";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

@*<script src="../../Scripts/IG/ig.ui.min.js" type="text/javascript"></script>
<script  type="text/javascript" src='@Url.Content("~/Scripts/Samples/combined/min/ig.ui.min.js")' />
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

<script type="text/javascript">
          $(function () {
              $('#grdMealInfo').live('iggridupdatingrowadded', function () {
                  var ok = confirm("Are you sure to add new record.");
                  if (ok) {
                      $('#grdMealInfo').igGrid("saveChanges")
                  }
              });
              $('#grdMealInfo').live('iggridupdatingrowdeleted', function (event, ui) {
                  var ok = confirm('Do you want to delete this row');
                  if (ok) {
                      $("#grdMealInfo").igGrid("saveChanges");
                  }
              });
          });
</script>

<h2>MealInfo</h2>

<div>
     @Html.Infragistics().Grid("grdMealInfo", Model.GridVirtualization)
</div>

Model:

public class GridVirtualizationModel
    {
        public GridVirtualizationModel()
        {
            GridVirtualization = new GridModel();
        }

        public GridModel GridVirtualization { get; set; }
    }

Dynamic Property Model:

public class MealEntry : DynamicObject
    {
        // The inner dictionary.
        Dictionary<string, object> properties = new Dictionary<string, object>();
 
        // This property returns the number of elements
        // in the inner dictionary.
        public int Count
        {
            get
            {
                return properties.Count;
            }
        }

        // If you try to get a value of a property
        // not defined in the class, this method is called.
        public override bool TryGetMember(GetMemberBinder binder, out object result)
        {         
            //string name = binder.Name.ToLower();
            string name = binder.Name;
            return properties.TryGetValue(name, out result);
        }

        // If you try to set a value of a property that is
        // not defined in the class, this method is called.
        public override bool TrySetMember(SetMemberBinder binder, object value)
        {
            // Converting the property name to lowercase
            // so that property names become case-insensitive.
            properties[binder.Name.ToLower()] = value;

            // You can always add a value to a dictionary,
            // so this method always returns true.
            return true;
        }
    }
