Cell Merging - WinForms Data Grid, DevExpress

Watch Video Run Demo

When cell merging is enabled, you can prevent cells in a specific column from being merged by setting the column’s OptionsColumn.AllowMerge property to DefaultBoolean.False.

You can also handle the View’s GridView.CellMerge event to merge cells manually.


  • When cell merging is enabled, specific features (such as cell editing, multiple row selection, etc.) are not available. Read the following topic for more information: Cells.
  • An AdvBandedGridView does not support the Cell Merging feature because this View allows column cells to be arranged in several lines (cells that belong to a single column may not be neighboring cells). Use the BandedGridView instead.
  • If the GridOptionsView.ShowPreview option is set to true, neighboring cells with identical values cannot be merged regardless of the AllowCellMerge property’s value.
