Remarks

Enumerating the collection in C# or Microsoft Visual Basic

A ColumnDefinitionCollection is enumerable, so you can use language-specific syntax such as foreach in C# to enumerate the items in the collection. The compiler does the type-casting for you and you won't need to cast to IEnumerable<ColumnDefinition> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with a ColumnDefinition constraint.

Properties

Item[Int32] Item[Int32] Item[Int32] Item[Int32]

Gets or sets the element at the specified index.

This member is not implemented in C++T this[int index] { get; set; }Property Item(index As Integer) As TT this[int index] { get; set; }
Parameters
index

The zero-based index of the element to get or set.

Value
T T T T

The element at the specified index.

Exceptions

index is not a valid index in the System.Collections.Generic.IList`1.

The property is set and the System.Collections.Generic.IList`1 is read-only.

Size Size Size Size

Gets the size (count) of the collection.

public : unsigned short Size { get; }This member is not implemented in C#This member is not implemented in VB.Net// This API is not available in Javascript.
Value
unsigned short uint uint uint

The count of items in the collection.

Methods

Append(ColumnDefinition) Append(ColumnDefinition) Append(ColumnDefinition) Append(ColumnDefinition)

Adds a new item to the collection.

Returns the ColumnDefinition located at the specified index.

public : ColumnDefinition GetAt(unsigned int index)This member is not implemented in C#This member is not implemented in VB.Net// This API is not available in Javascript.
Parameters
index
unsigned int UInt32 UInt32 UInt32

The integer index for the value to retrieve.

Returns

GetEnumerator() GetEnumerator() GetEnumerator() GetEnumerator()

Returns an enumerator that iterates through the collection.

This member is not implemented in C++IEnumerator<T> GetEnumerator()Function GetEnumerator As IEnumerator(Of T)IEnumerator<T> GetEnumerator()
Returns

An enumerator that can be used to iterate through the collection.

GetMany(UInt32, ColumnDefinition[]) GetMany(UInt32, ColumnDefinition[]) GetMany(UInt32, ColumnDefinition[]) GetMany(UInt32, ColumnDefinition[])

Retrieves multiple elements in a single pass through the iterator.

public : unsigned short GetMany(unsigned int startIndex, ColumnDefinition[] items)This member is not implemented in C#This member is not implemented in VB.Net// This API is not available in Javascript.
Parameters
startIndex
unsigned int UInt32 UInt32 UInt32

The index from which to start retrieval.

items
ColumnDefinition[] ColumnDefinition[] ColumnDefinition[] ColumnDefinition[]

Provides the destination for the result. Size the initial array size as a "capacity" in order to specify how many results should be retrieved.

Returns
unsigned short uint uint uint

The number of items retrieved.

GetView() GetView() GetView() GetView()

Gets an immutable view into the collection.

public : IVectorView<ColumnDefinition> GetView()This member is not implemented in C#This member is not implemented in VB.Net// This API is not available in Javascript.
Returns

Returns

The index of item if found in the list; otherwise, -1.
