Adds a copy of the drawing (picture, chart, etc.) to the worksheet.

public T AddCopy(T item)
Public Function AddCopy(item As T) As T
Parameters
item
T

The drawing (picture, chart, etc.) which will be copied to the worksheet.

Returns
T

BringForward(T)

Moves the specified item one position forward in the drawings.

public void BringForward(T item)
Public Sub BringForward(item As T)
Parameters
item
T

The item to move forward.

Remarks

The index of the item will not be updated if the item in front is a different type. But it will still update the position.

BringForward(Int32)

Moves the item at the specified index one position forward in the drawings.

Public Sub BringForward(index As Integer)
Parameters
index
System.Int32

The index of the item to move forward.

Remarks

The index of the item will not be updated if the item in front is a different type. But it will still update the position.

BringToFront(T)

Brings the specified item to the front of the drawings.

public void BringToFront(T item)
Public Sub BringToFront(item As T)
Parameters
item
T

The item to bring to the front.

BringToFront(Int32)

public void BringToFront(int index)
Public Sub BringToFront(index As Integer)
Parameters
index
System.Int32

The index of the item to bring to the front.

Clear()

Removes all elements from the ExcelDrawingCollection<T>.

public void Clear()
Public Sub Clear

Contains(T)

Determines whether an element is in the ExcelDrawingCollection<T>.

public bool Contains(T item)
Public Function Contains(item As T) As Boolean
Parameters
item
T

The object to locate in the ExcelDrawingCollection<T>.

Returns
System.Boolean

true if item is found; otherwise, false.

GetEnumerator()

Returns an enumerator that iterates through the ExcelDrawingCollection<T>

public IEnumerator<T> GetEnumerator()
Public Function GetEnumerator As IEnumerator(Of T)
Returns
System.Collections.Generic.IEnumerator<T>
