Hello Andrew,

I am glad that you find my suggestion helpful and were able to solve your issue.

Thank you for using Infragistics components.

Thanks much for this.  This really helped.  Here is the solution I ended up coming up with.  The model was an array of gridModels.  

View: 

@foreach (var m in Model)

{

@(Html.Infragistics().Grid(m))
<br />
}

Controller: 

[ActionName("editing")]
public ActionResult GridUpdating(int QuotaID, string IONumber)
{
var modelList = new List <GridModel>();

//Infragistics Grid

var quotaDetailList = projectPricingBAL.getCostGridForQuotaFlatDemo(QuotaID);
GridModel gridModel = new GridModel();
gridModel.AutoGenerateColumns = false;
gridModel.ID = "Grid_QuotaEdit";
gridModel.PrimaryKey = "ID";
gridModel.DataSource = quotaDetailList.AsQueryable();
InitializeGridOptions(gridModel);

modelList.Add(gridModel); //add to an array

var quotaDetailList2 = projectPricingBAL.getCostGridForQuotaFlatDemo(25869); //hardcoded for testing

GridModel gridModel2 = new GridModel();
gridModel2.AutoGenerateColumns = false;
gridModel2.ID = "Grid_QuotaEdit2";
gridModel2.PrimaryKey = "ID";
gridModel2.DataSource = quotaDetailList2.AsQueryable();
InitializeGridOptions(gridModel2);

modelList.Add(gridModel2); //trying to add to an array

return View(modelList);
}
