![]() ![]() To adjust sizes to fit values in newly displayed rows while scrolling, call a resizing method in a Scroll event handler. Use the appropriate sizing-mode enumeration values with automatic or programmatic resizing. ![]() To avoid a performance penalty when working with large amounts of data, use a sizing mode that calculates displayed rows only.Īdjust sizes to fit values in displayed rows to avoid performance penalties when working with many rows. Set an automatic sizing property to a value that represents a content-based sizing mode. Initialize its width by setting the Width property or by calling the control AutoResizeColumn method after filling the control with data.Īdjust sizes automatically whenever cell contents change to avoid clipping and to optimize the use of space. Set AutoSizeMode to None and Resizable to False for the column. If the other columns use too much of the available space, set the MinimumWidth property of the last column.ĭisplay a fixed-width column, such as an icon or ID column. Set the AutoSizeMode property of the last column to Fill and use other sizing options for the other columns. Use column fill mode to avoid displaying the control background. Set large MinimumWidth values for columns that must always display some of their data or use a sizing option other than fill mode for specific columns. Set the AutoSizeColumnsMode property to Fill. Use column fill mode with values of varying importance. Initialize relative column widths by setting the column FillWeight properties or by calling the control AutoResizeColumns method after filling the control with data. Use column fill mode with display values of varying sizes. Use column fill mode for displaying similarly sized data in a relatively small number of columns that occupy the entire width of the control without displaying the horizontal scroll bar. The following table shows scenarios that you can use to adjust the default behavior or to use specific sizing options to achieve particular effects. ![]() You can also set specific height and width values.īy default, user resizing is enabled, automatic sizing is disabled, and cell values that are wider than their columns are clipped. Programmatic content-based resizing lets you make opportunistic size adjustments based on cell values at the time of the method call. In content-based automatic sizing modes, sizes change to fit new display values. In column fill mode, column widths change when the control width changes for example, when the control is docked to its parent form and the user resizes the form. Users can make size adjustments by dragging or double-clicking row, column, or header dividers. The following table shows these occurrences. DataGridView rows, columns, and headers can change size as a result of many different occurrences. ![]()
