Hi Tony,

you can use some jQuery code similar to this one below, it will do it. At the moment there isn't a way to do this by setting just a column option in the grid configuration, but it's on the list.

           $("#grid1").live("iggridrendered", function (event, args) {
                // right-justify text in the third column
                args.owner.element.find("tr td:nth-child(3)").css("text-align", "right"); // or "center"
            });

In the context of MVC, it could be declared like:

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
    <script type="text/javascript">
        $(document).ready(function () {
            $("#grid1").live("iggridrendered", function (event, args) {
                // right-justify text in the third column
                args.owner.element.find("tr td:nth-child(3)").css("text-align", "right");
            });

        });

    </script>
    <%= Html.Infragistics().Grid(Model).ID("grid1").Height("250px").Columns(column =>

// rest of the grid definition

Hope it helps,

All you need to do is hook up to the headerCellRendered event of the igGrid and in the handler consider the ui.columnKey param.
Thus you can apply the text justification only to the desired columns.

Here's a code sample of how to accomplish this:
(I'm attaching a working HTML page that illustrates the sample code) 

$("#Grid1").igGrid({
     autoGenerateColumns: false,
     dataSource: sourceData,
     primaryKey: "ProjectID",
     columns: [
        { key: "ProjectID", headerText: "Project Id", width: 100, dataType: "number" },
        { key: "Name", headerText: "Name", width: 200, dataType: "string" },
        { key: "StartDate", headerText: "Start Date", width: 150, dataType: "date" },
        { key: "EndDate", headerText: "End Date", width: 150, dataType: "date" },
        { key: "IsPostponed", headerText: "Is Postponed", width: 100, dataType: "bool" }
    ],
    headerCellRendered: function(evt, ui) {
        if(ui.columnKey === "Name" || ui.columnKey === "StartDate")
        {
            $(ui.th).css("text-align", "center");
        }
    }
});

Cheers!
