## CustomDocumentPropertyCollection class

A collection of custom document properties.



**Inheritance:** [`CustomDocumentPropertyCollection`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection)



The CustomDocumentPropertyCollection type exposes the following members:

### Properties
| Property | Description |
| :- | :- |
| [capacity](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/capacity) | Gets or sets the number of elements that the array list can contain. |


### Methods
| Method | Description |
| :- | :- |
| [`get(self, name)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/get/#system.string) |  |
| [`get(self, index)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/get/#int) |  |
| [`index_of(self, name)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/index_of/#system.string) |  |
| [`index_of(self, item, index)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/index_of/#aspose.cells.properties.documentproperty-int) | Searches for the specified object and returns the zero-based index of the first occurrence within the range of elements in the array list that extends from the specified index to the last element. |
| [`index_of(self, item, index, count)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/index_of/#aspose.cells.properties.documentproperty-int-int) | Searches for the specified object and returns the zero-based index of the first occurrence within the range of elements in the array list that starts at the specified index and contains the specified number of elements. |
| [`copy_to(self, array)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/copy_to/#list) | Copies the entire array list to a compatible one-dimensional array list, starting at the beginning of the target array list. |
| [`copy_to(self, index, array, array_index, count)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/copy_to/#int-list-int-int) | Copies a range of elements from the array list to a compatible one-dimensional array list, starting at the specified index of the target array list. |
| [`last_index_of(self, item)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/last_index_of/#aspose.cells.properties.documentproperty) | Searches for the specified object and returns the zero-based index of the last occurrence within the entire array list. |
| [`last_index_of(self, item, index)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/last_index_of/#aspose.cells.properties.documentproperty-int) | Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the array list that extends from the first element to the specified index. |
| [`last_index_of(self, item, index, count)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/last_index_of/#aspose.cells.properties.documentproperty-int-int) | Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the array list that contains the specified number of elements and ends at the specified index. |
| [`add(self, name, value)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/add/#system.string-system.string) | Creates a new custom document property of the **PropertyType.String**  data type. |
| [`add(self, name, value)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/add/#system.string-int) | Creates a new custom document property of the **PropertyType.Number**  data type. |
| [`add(self, name, value)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/add/#system.string-system.datetime) | Creates a new custom document property of the **PropertyType.DateTime**  data type. |
| [`add(self, name, value)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/add/#system.string-bool) | Creates a new custom document property of the **PropertyType.Boolean**  data type. |
| [`add(self, name, value)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/add/#system.string-float) | Creates a new custom document property of the **PropertyType.Float**  data type. |
| [`binary_search(self, item)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/binary_search/#aspose.cells.properties.documentproperty) | Searches the entire sorted array list for an element using the default comparer and returns the zero-based index of the element. |
| [`add_link_to_content(self, name, source)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/add_link_to_content/#system.string-system.string) | Creates a new custom document property which links to content. |
| [`update_linked_property_value(self)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/update_linked_property_value/#) | Updates values of all custom properties that are linked to content(use
<br/>cell value of linked range to update value of custom property). |
| [`update_linked_range(self)`](/cells/python-net/aspose.cells.properties/customdocumentpropertycollection/update_linked_range/#) | Updates all ranges that are linked to custom properties(use the value of
<br/>custom document property to update cell value of linked range). |



### Remarks 


Each [`DocumentProperty`](/cells/python-net/aspose.cells.properties/documentproperty) object represents a custom property of a container document.

### Example 


```python
from aspose.cells import Workbook

# Instantiate a Workbook object
workbook = Workbook("book1.xls")
# Retrieve a list of all custom document properties of the Excel file
customProperties = workbook.worksheets.custom_document_properties

```
