DataGridView.RowHeadersWidthSizeMode Property

Gets or sets a value indicating whether the width of the row headers is adjustable and whether it can be adjusted by the user or is automatically adjusted to fit the contents of the headers.

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

member RowHeadersWidthSizeMode : DataGridViewRowHeadersWidthSizeMode with get, set

Property Value

Type: System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode
A DataGridViewRowHeadersWidthSizeMode value indicating the mode by which the width of the row headers can be adjusted. The default is EnableResizing.

ExceptionCondition
InvalidEnumArgumentException

The specified value when setting this property is not a valid DataGridViewRowHeadersWidthSizeMode value.

When this property is set to an automatic sizing mode, the width of the row headers cannot be adjusted by the user.

To adjust the height of the row headers programmatically, use the AutoResizeRowHeadersWidth method or set the RowHeadersWidth property.

To set the sizing mode for the column headers, use the ColumnHeadersHeightSizeMode property.

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

NoteNote

The DataGridView control does not support double buffering. If DoubleBuffered is set to true in a derived DataGridView control, users will not receive visual feedback when resizing rows, columns, or headers or when reordering columns.

The following code example illustrates how to use this property in a DataGridView control intended primarily for display. In this example, the visual appearance of the control is customized in several ways and the control is configured for limited interactivity. This example is part of a larger example available in the DataGridViewCellStyle class overview.
