30 5.3.1 Sizing Options in the Windows Forms Data Grid View Control 30 5.3.2 Resizing with the Mouse. If you explicitly set Resizable to True or False, however, the specified value overrides the control value is for that row or column. 28 5.2.2 Row Pre Paint and Post Paint 29 5.3 Autosizing. 33 5.3.5 Customizing Content-based Sizing Behavior. By default, the Resizable property value is based on the Allow User To Resize Columns property value for columns and the Allow User To Resize Rows property value for rows.
For all sizing enumerations, values with names that refer to displayed cells limit their calculations to cells in displayed rows. If you configure both rows and columns for content-based automatic sizing and Wrap Mode is enabled, the Data Grid View control will adjust sizes whenever cell contents changed and will use an ideal cell height-to-width ratio when calculating new sizes. For example, if rows but not columns are configured for automatic sizing and Wrap Mode is enabled, users can drag column dividers to change the width of a column and row heights will automatically adjust so that cell contents are still fully displayed. With these values, you can limit which cells are used to calculate the preferred sizes. The enumerations used by sizing properties and methods have similar values for content-based sizing. For maximum performance, use programmatic resizing instead so that you can resize at specific times, such as immediately after new data is loaded.
To avoid performance penalties, use the automatic sizing modes that calculate sizes based only on the displayed rows rather than analyzing every row in the control.
Use content-based automatic resizing with caution when working with large amounts of data.
The value of this property is based on the column's Auto Size Mode property value unless that value is Not Set, in which case the control's Auto Size Columns Mode value is inherited.
You must then call the Auto Resize Columns method to adjust the column widths to the calculated ideal.
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.
Because Not Set restores the value inheritance, the Resizable property will never return a Not Set value unless the row or column has not been added to a Data Grid View control.
