ComponentOne grids are relied upon by banks and other financial institutions for high-performance, high-throughput data visualization and manipulation. In some financial applications it becomes necessary to merge cells, similar in functionality to popular spreadsheet applications, in order to enable the user to work with data in a form-like fashion. It is common for end users who are analyzing large amounts of data to require Excel-style merging, where the user selects arbitrary ranges that can be merged and unmerged. This feature can be implemented in the FlexGrid for WinForms. Here is a screenshot that shows the implementation of this feature: The sample can be downloaded from the following link: http://our.componentone.com/samples/winforms-excelstylemerge
