    I have a grid that lists people.  When it loads, I need to select a row matching the key I submit and then ensure the row is visible in the window.  How do I do this?  My attempt (based on what I know of the TreeList):

        .Columns(columns =>
            columns.Command(command => command
            columns.Bound(p => p.FirstName)
                .Filterable(ftb => ftb.Cell(cell => cell.Operator("contains")
            columns.Bound(p => p.LastName)
                .Filterable(ftb => ftb.Cell(cell => cell.Operator("contains")
        .Selectable(s => s.Mode(GridSelectionMode.Single))
        .Filterable(ftb => ftb.Mode(GridFilterMode.Row))
        .HtmlAttributes(new { style = "height:550px;" })
        .DataSource(dataSource => dataSource
            .Read(read => read.Action("IndexJson", "Patients").Data("getData"))
        ).Events(e => e.DataBound("onGridDataBound")))



    function onGridDataBound(e) {
        // Handle the dataBound event.
        var grid = e.sender;
        alert(grid == null);
        var personId = $("#personId").val();
        if (grid != null)
            var dataItem = grid.dataSource.get(personId);
            alert(dataItem == null);
            if (dataItem != null)
                var row = $("tr[data-uid='" + dataItem.uid + "']");
                alert(row == null);
                if (row != null)

    Hello, Joel,

    Thank you for the provided code snippets. 

    The get() method depends on the Model.Id of the data source. What I have noticed is that in the current declaration, Model.Id is missing. Could you add it and let me know if the issue persists?

            .Model(model => model.Id(p => p.ProductId))

    Looking forward to your reply.


    Kind Regards,
