Ignite UI API Reference

ui.igGridCellMerging

ui.igGridCellMerging_image

Merged cell feature of the igGrid allows you to combine cells in a column that are next to each other and have the same values. This is very useful after a column is sorted, because the cells that have the same values are merged.

The following code snippet demonstrates how to initialize the igGrid control.
