# MergeBlockInfo.Apply Method

> Stores the meta data (filters, sorting instructions and the block merging condition) in the SubTextPart which represents the block. Manipulating any of the aforementioned collections does not update the block automatically, so this method must be called to actually store changes. If a MergeBlockInfo instance is not based on an existing SubTextPart, this method throws an exception.
