I am using MVC5 and Infragistics 2013.2.  My web page contains an iggrid.  I need to validate the data and indicate to the user when there is a problem.  The validation code below works fine for me when the user is editing the iggrid.  However, the iggrid may also be "prepopulated" with rows as a result of data that the view receives from the controller:

     .DataSource(Model.Products.AsQueryable())

The problem I have is that the code below is not showing validation errors in the prepopulated rows, unless the user clicks in one of the cells and makes a change.  Then, the error is displayed.

Any ideas on how to show validation errors in data that is prepopulated into the iggrid?  Many thanks.  Tory.

@(Html.Infragistics()
    .Grid(Model.PvpProduct)
    .ID("igGrid")
    .Height("500px")
    .Width("100%")
    .AutoGenerateColumns(false)
    .AutoGenerateLayouts(false)
    .RenderCheckboxes(true)
    .PrimaryKey("ID")
    .Columns(column =>
    {
        column.For(x => x.FPONumber).HeaderText("FPO Number").Width("100%");

        // Many columns not shown.
    })
    .Features(feature =>
    {
        feature.Updating().ColumnSettings(cs =>
        {
            cs.ColumnSetting().ColumnKey("FPONumber").Validation(true).EditorOptions("validatorOptions:{checkValue:validateFPONumber}").Required(false);

            // Many columns not shown.
        });
    })
    .DataSource(Model.Products.AsQueryable())
    .AutoCommit(true)
    .DataBind()
    .Render()
)

<script type="text/javascript">
    function validateFPONumber(evt, ui) {
        if (ui.value.length > 9) {
            ui.message = "Invalid FPO Number.";
            return false;
        }

        return true;
    }
</script>
