The ColumnDefinition type exposes the following members.

  NameDescription
Public methodColumnDefinitionInitializes a new instance of the ColumnDefinition class.
Top

  NameDescription
Public propertyActualWidthGets a value that represents the actual calculated width of a ColumnDefinition.
Public propertyDispatcherGets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
Public propertyMaxWidthGets or sets a value that represents the maximum width of a ColumnDefinition.
Public propertyMinWidthGets or sets a value that represents the minimum width of a ColumnDefinition.
Public propertyWidthGets the calculated width of a ColumnDefinition element, or sets the GridLength value of a column that is defined by the ColumnDefinition.

  NameDescription
Public methodCheckAccessDetermines whether the calling thread has access to this object. (Inherited from DependencyObject.)
Public methodClearValueClears the local value of a dependency property. (Inherited from DependencyObject.)
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetAnimationBaseValueReturns any base value established for a Windows Phone dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodReadLocalValueReturns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
Public methodSetValueSets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

You can set a ColumnDefinition for each column in a Grid. If you do not specify a ColumnDefinition, by default the Grid will contain a single column with star sized width.

To set a group of ColumnDefinition elements by using code, add the ColumnDefinition to a ColumnDefinitionCollection.

ColumnDefinition uses a GridLength structure to describe its width characteristics. GridLength allows a ColumnDefinition to support variable distribution of available space.

The following example uses three ColumnDefinitions and three RowDefinitions to create a grid that has nine cells, such as in a worksheet. Each cell contains a TextBlock element that represents data, and the top row contains a TextBlock with the ColumnSpan property applied. To show the boundaries of each cell, the ShowGridLines property is enabled.
