Remarks

XAML for Xamarin.Forms supports the following property for the ColumnDefinition class:

Property Value
Width

"*" or "Auto" to indicate the corresponding GridUnitType enumeration values, or a number to indicate an absolute width.

App developers can specify GridUnitType values for the Width property in XAML by nesting ColumnDefinition tags inside tags for the ColumnDefinitions collection property. The following example demonstrates setting three column widths to each of the three valid GridUnitType values:


<Grid.ColumnDefinitions>
    <ColumnDefinition Width="Auto" />
    <ColumnDefinition Width="*" />
    <ColumnDefinition Width="100" />
</Grid.ColumnDefinitions>

Constructors

Fields
