VIBlend DataGridView for WinForms offers multiple unique features that cannot be found in other Windows Forms data grid controls. These include multi-level hierarchies on rows and columns, rows grouping, pivot tables, and built-in OLAP capabilities. One of the main drawbacks of the traditional OLAP style rows layout is that it takes a lot of screen space.
This could be improved by using the compact style layout. In this mode the rows of the pivot table are rendered in a tree-like structure.
Switching from default to compact style rendering is very easy. It requires setting the value of RowsHierarchy.CompactStyleRendering property to true:
grid.RowsHierarchy.CompactStyleRenderingEnabled = true;
grid.RowsHierarchy.CompactStyleRenderingEnabled = True
You can switch between traditional and compact style rendering at runtime. The feature is also availalbe in VIBlend DataGrid for Silverlight.
