ColumnDefinitionCollection Class

Remarks

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>
