XAML Values

double

Double

String representation of a Double value. This is interpreted as a device-independent unit (1/96th inch) measurement. Strings need not explicitly include decimal points. For instance a value of 1 is acceptable.

qualifiedDouble

A double value as described above, followed by one of the following unit declaration strings: px, in, cm, pt.

px (default) is device-independent units (1/96th inch per unit)

in is inches; 1in==96px

cm is centimeters; 1cm==(96/2.54) px

pt is points; 1pt==(96/72) px

Auto

Enables autosizing behavior. See Remarks.

Property Value

Type: System.Double
The width of the column. The default is Double.NaN, which automatically sizes to the largest column item that is not the column header.

Identifier field

WidthProperty

Metadata properties set to true

AffectsMeasure

To get the exact width when this property is set to Double.NaN, use the ActualWidth property.

The following example shows how to set the Width property.

GridViewColumn gvc1 = new GridViewColumn();
gvc1.DisplayMemberBinding = new Binding("FirstName");
gvc1.Header = "FirstName";
gvc1.Width = 100;
<GridViewColumn DisplayMemberBinding=
                    "{Binding Path=FirstName}" 
                Header="First Name" Width="100"/>
