DataGridViewRowHeadersWidthSizeMode Enumeration

Defines values for specifying how the row header width is adjusted.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

type DataGridViewRowHeadersWidthSizeMode

Member nameDescription
AutoSizeToAllHeadersThe row header width adjusts to fit the contents of all the row header cells.
AutoSizeToDisplayedHeadersThe row header width adjusts to fit the contents of all the row headers in the currently displayed rows.
AutoSizeToFirstHeaderThe row header width adjusts to fit the contents of the first row header.
DisableResizingUsers cannot adjust the column header width with the mouse.
EnableResizingUsers can adjust the column header width with the mouse.

By default, users can resize the width of the row headers. You can disable this ability to set a fixed width, or you can use a content-based automatic sizing mode, which also disables user resizing.

The DataGridView control can adjust the width of its row headers to fit all their contents, only the contents of the first header, or only the contents of currently displayed headers. Calculating the new width using a subset of headers is useful to avoid a performance penalty when working with many rows of data.

This enumeration is used by the DataGridView control RowHeadersWidthSizeMode property and AutoResizeRowHeadersWidth method.

For more information about sizing modes, see Sizing Options in the Windows Forms DataGridView Control.

The following code example illustrates the use of this enumeration in a display-only, non-interactive DataGridView control.
