The sizing mode for a column is actually determined by its Inherited Auto Size Mode property. To configure the sizing mode for headers and rows and for columns that do not override the control value, set one or more of the following Data Grid View properties: To override the control's column sizing mode for an individual column, set its Auto Size Mode property to a value other than Not Set. Column fill mode causes the visible columns in the control to fill the width of the control's display area.
For more information about this mode, see the Column Fill Mode section below. 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. For example, you might programmatically resize all columns immediately after loading data, or you might programmatically resize a specific row after a particular cell value has been modified. Get Preferred Width() methods or by calling protected resizing method overloads in a derived Data Grid View control. Note: If you maintain cell values in a custom data cache using virtual mode, automatic sizing occurs when the user edits a cell value but does not occur when you alter a cached value outside of a Cell Value Pushed event handler. In this case, size adjustment occurs whenever cell contents change.
The new sizes are automatically calculated to display all cell contents without clipping.
