DataGrid.RowHeaderWidth Property


Gets or sets the width of the row header column.

Namespace:   System.Windows.Controls
Assembly:  PresentationFramework (in PresentationFramework.dll)

public double RowHeaderWidth { get; set; }

Property Value

Type: System.Double

The width of the row header column, in device-independent units (1/96th inch per unit). The registered default is NaN. For more information about what can influence the value, see DependencyProperty.

When you set a value for the RowHeaderWidth property, it must be equal to or greater than 0.0. Set this property to NaN ("Auto" in XAML) to make the row header automatically adjust its size to fit its content.

Double.PositiveInfinity is not a valid value for this property. The value restrictions on the Double value are enforced by a ValidateValueCallback mechanism. If you attempt to set a value that is not valid, a run-time exception is thrown.
