Parameters

element
An item in the Data Set.
userTag
Tag of the item to find.
tree
true to evaluate the Data Set as a tree; false to evaluate the Data Set as a list.

Return Value

The last item in the Data Set with the specified Tag, or a null reference (Nothing in Visual Basic) if an item with the specified Tag was not found.

Example

For an example, refer to Load.

Remarks

For the sake of the following illustrations, the order of siblings is top to bottom. Therefore last is the item closest to the bottom.

If the Data Set is evaluated as a tree structure, this method returns the last item on the same level as element with the same parent as element, that has Tag userTag.

Please note that the numbering of the items of interest in this first illustration is arbitrary and does not imply order.

If the passed object points to:The method returns an object pointing to:
Item 1The last sibling (same level, same parent) of Item 1 that has Tag userTag, if such an item exists. If such an item does not exist, the method returns null. Searching begins at the bottom.
Item 2The last sibling (same level, same parent) of Item 2 that has Tag userTag, if such an item exists. If such an item does not exist, the method returns null. Searching begins at the bottom.
Item 3The last sibling (same level, same parent) of Item 3 that has Tag userTag, if such an item exists. If such an item does not exist, the method returns null. Searching begins at the bottom.

If the Data Set is evaluated as a list, this method returns the last item in the entire list that has Tag userTag. Searching begins at the bottom of the list.

Please note that the numbering of the items in the following illustration does indicate the order of the items when the Data Set is evaluated as a list.

If the passed object points to:The method returns an object pointing to:
Item 1The last item in the list that has Tag userTag, if such an item exists. If an item with Tag userTag is not found, null is returned. Searching begins at the bottom.
Item 14The last item in the list that has Tag userTag, if such an item exists. If an item with Tag userTag is not found, null is returned. Searching begins at the bottom.
Item 22The last item in the list that has Tag userTag, if such an item exists. If an item with Tag userTag is not found, null is returned. Searching begins at the bottom.

The following methods will also help you find elements in the Data Set with a specific Tag:

FindFirstElement

FindPreviousElement

FindNextElement

The following methods will help you find specific modules in the Data Set:

FindModule

FindModuleByIndex
