XAML Values
Property Value
Type: System::DoubleThe column gap, in device independent pixels. A value of Double::NaN (equivalent to an attribute value of "Auto") indicates that the column gap is equal to the LineHeight property. The default is Double::NaN.
Getting this property returns the current column gap. Setting this value changes the currently effective column gap, and may cause content to reflow.
The column gap cannot exceed the current PageWidth minus any PagePadding. If the value of the ColumnGap property exceeds this limit, the effective column gap is reduced to observe this limit.
This property has no effect if ColumnWidth is nullptr.
The following example shows how to set the ColumnGap property programmatically.
