DataGrid.RowHeaderWidth Property


Gets or sets the width of the row header column.

 property double RowHeaderWidth { double get(); void set(double value); };
public double RowHeaderWidth { get; set; }
member this.RowHeaderWidth : double with get, set
Public Property RowHeaderWidth As Double

Property Value

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.
