So I have a method in my busniess logic that I am assigning defaults to and creating a List:

var ppc1Result = POCMethods.GetPPCRatesAndStatusesInRowsOverallMedSurg(PPCRatesAndStatusesInRowsOverallMedSurgDTO.Default()).ToList();

When I debug the data I want is there in the variable 'ppc1Result', but how do I use this list in a WebGrid. When I write out the column names from the list, I am getting an error saying the column name doesn't exist, here's my WebGrid:

@{
    var grid = new WebGrid(ppc1Result, canPage: true, rowsPerPage: 5,
    selectionFieldName: "selectedRow", ajaxUpdateContainerId: "measuresMain");
    grid.Pager(WebGridPagerModes.NextPrevious);
}

<div id="measuresMain">
    @grid.GetHtml(
        tableStyle: "webGrid",
        headerStyle: "header",
        alternatingRowStyle: "alt",
        selectedRowStyle: "select",
        columns: grid.Columns(
                grid.Column("DischargeswAtRisk", "DischargesAtRisk"),
                grid.Column("DischargesWithPPC", "DischargesWithPPC"),
                grid.Column("DRGType", "DRGType"),
                grid.Column("NormativeRate", "NormativeRate"),
                grid.Column("OverallDischargeCounts", "OverallDischargeCounts"),
                grid.Column("SumWeight", "SumWeight"),
                grid.Column("TotalImpact", "TotalImpact")
    ))
</div>

This results in an error.
