Merged Cells Support in Telerik UI for WinForms GridView

With 2024 Q3 release, the Telerik UI for WinForms introduces support for merged cells in the GridView control. Consecutive / serial cells with equal values can be merged vertically or horizontally with this new enhancement.

You can easily edit the merged cells in two ways – edit only the current cell or edit all merged cells at once. When the merge cells functionality is enabled, the WinForms GridView control exposes a CellMerging event, triggered when two cells are going to be merged. Customizing the merged cells is also possible via the ViewCellFormatting event of the control allowing you to change the color of a merged cell for example.

Last mut not least, the Telerik UI for WinForms GridView merge cell capability enables you to define merge cell rules at column or template level.

Check out the Telerik UI for WinForms GridView merged cell documentation for more details.

This new feature extends the users’ selection experience by allowing them to select or deselect rows from the grid by using a checkbox.
