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.

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

<object Width="double"/>
- or –
<object Width="qualifiedDouble"/>
- or -
<object Width="Auto"/>



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.


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


Enables autosizing behavior. See Remarks.
