From the link then I dont see what it is I'm doing wrong.
Column @ Index 1
<ig:BoundDataField DataFieldName="some_id" Key="some_id" Width="150px" CssClass="searchTxt">
<Header Text="SomeID" />
</ig:BoundDataField>
InitRow Code:
protected void Report_Grid_InitializeRow(object sender, Infragistics.Web.UI.GridControls.RowEventArgs e)
{
e.Row.CssClass = "summaryRow";
e.Row.Items[1].CssClass = "summaryCell";
}
Rendered Table Output:

What is it that I'm doing incorrectly that my css class isn't rendered in code?
