ERROR_CANTSCROLLBACKWARDS - 771 (0x303)
The data provider cannot scroll backwards through a result set.
Updated: Feb 21, 2026
Technical Meaning
The ERROR_CANTSCROLLBACKWARDS error code indicates that a data provider is unable to traverse backward through a result set. This typically occurs in scenarios where the application or system attempts to access previous items within a dataset, but the underlying data source does not support such operations.
Error Details
This error is specific to situations where a data provider (such as a database engine, file system, or custom data retrieval mechanism) encounters limitations that prevent it from moving backward through a result set. The error may be triggered by various operations, including but not limited to pagination, cursor-based navigation, and reverse iteration over a dataset.
Usage Context
The ERROR_CANTSCROLLBACKWARDS error is commonly encountered in applications that require bidirectional traversal of data sets. For example, when implementing a user interface feature that allows users to navigate through a list of items both forward and backward, the application may encounter this error if the underlying data source does not support reverse iteration.
Developer Interpretation
Developers should interpret this error as an indication that the current operation is not supported by the data provider. This could be due to limitations in the data retrieval mechanism or specific constraints imposed by the data source itself. Developers may need to adjust their application logic to handle such scenarios gracefully, possibly by implementing alternative methods for backward traversal.
Related Errors
ERROR_NO_MORE_ITEMS(0x103): Indicates that there are no more items in a result set.ERROR_HANDLE_EOF(0x802): Indicates an end-of-file condition on a file handle, which may be related to data traversal operations.
FAQ
Q: What does the ERROR_CANTSCROLLBACKWARDS error mean?
A: It indicates that the data provider cannot traverse backward through a result set. This is typically due to limitations in the underlying data retrieval mechanism or constraints imposed by the data source.
Q: How can I handle this error in my application?
A: You should design your application logic to gracefully handle scenarios where bidirectional traversal is not supported. Consider implementing alternative methods for backward navigation, such as caching previous items or using a different data retrieval strategy.
Summary
The ERROR_CANTSCROLLBACKWARDS error code signifies that the data provider cannot support backward traversal through a result set. Developers should be aware of this limitation and design their applications to handle such scenarios appropriately.
