For example, if you call the Auto Resize Rows(Data Grid View Auto Size Rows Mode, Boolean) overload of the Auto Resize Rows method and pass in a value of false for the Boolean parameter, the overload will calculate the ideal heights and widths for cells in the row, but it will adjust the row heights only. You can customize sizing behaviors when working with derived Data Grid View cell, row, and column types by overriding the Data Grid View Cell. The protected resizing method overloads are designed to work in pairs to achieve an ideal cell height-to-width ratio, avoiding overly wide or tall cells.
