When I needed to modify background of Infragistics GroupByRow element using CSS class from an external stylesheet I thought – no problem. Link stylesheet to the page, modify grid’s property GroupByRowStyleDefault by setting CssClass:
And that should do it. Well, it didn’t work, the background hasn’t changed so I looked at page HTML source.
Infragistics UltraWebGrid has a nice feature – OutlookGroupBy mode – which allows to group rows by common field either by dragging them into a GroupBy Box or programmatically.
The only drawback – when you have several levels of groupings (group within a group) – the outer group shows count of inner groups, not total number of individual rows within a group.
When I contacted Infragistics tech support asking how to show total count of rows within a group they told me it was impossible. Well, turned out it wasn’t entirely true.
