### Methods
| Method | Description |
| :- | :- |
| [`copy_to(self, array)`](/cells/python-net/aspose.cells.drawing/checkboxcollection/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.drawing/checkboxcollection/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. |
| [`index_of(self, item, index)`](/cells/python-net/aspose.cells.drawing/checkboxcollection/index_of/#aspose.cells.drawing.checkbox-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.drawing/checkboxcollection/index_of/#aspose.cells.drawing.checkbox-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. |
| [`last_index_of(self, item)`](/cells/python-net/aspose.cells.drawing/checkboxcollection/last_index_of/#aspose.cells.drawing.checkbox) | 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.drawing/checkboxcollection/last_index_of/#aspose.cells.drawing.checkbox-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.drawing/checkboxcollection/last_index_of/#aspose.cells.drawing.checkbox-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, top_row, left_column, height, width)`](/cells/python-net/aspose.cells.drawing/checkboxcollection/add/#int-int-int-int) | Adds a checkBox to the collection. |
| [`binary_search(self, item)`](/cells/python-net/aspose.cells.drawing/checkboxcollection/binary_search/#aspose.cells.drawing.checkbox) | Searches the entire sorted array list for an element using the default comparer and returns the zero-based index of the element. |



### Example 


```python
from aspose.cells import Workbook

# Create a new Workbook.
workbook = Workbook()
# Get the first worksheet in the workbook.
sheet = workbook.worksheets[0]
