Related Product Version: 1.3.34.1
Last Updated: October 22, 2025
We are excited to announce version 1.3.34.1, a major update that significantly enhances the Data Slicer visual’s date formatting capabilities. This release introduces a comprehensive set of features designed to provide greater customization, improve data accuracy, and streamline the user experience — all while ensuring robust and reliable performance.
New features
Input-Output masks / Date formats
A brand-new feature giving users granular control over date formats for both data entry (input) and display (output) across Interval and Textbox modes.
Highlights:
- Independent control: Users can now set different formats for date input and output, allowing greater flexibility than before.
- Location: The new Masks settings are located under the Values card in the Formatting settings panel.
- Context-sensitive visibility: The Masks section only appears when working with a valid date type data column.
Input mask behavior:
- By default, masks align with local date settings and the structure of the connected data column.
- Users can enter dates using the selected input mask format, or the default Power BI format.
- Selecting an input mask does not automatically change the output mask.
Output mask behavior:
- Selecting an output mask offers additional flexibility for data entry.
- The system automatically normalizes all valid inputs to match the output mask for consistency.
Data Slicer now supports a wider range of date formats to accommodate different regional and user preferences in both Textbox and Interval modes.
Newly supported formats: dd-mm-yyyy, mm-dd-yyyy, ddmmyyyy, mmddyyyy, yyyy-mm-dd
Format compatibility
This intelligent feature prevents invalid or conflicting date format combinations.
- Conflict prevention: The system automatically disables incompatible format options to avoid data conversion errors.
- Smart dropdown filtering: If Power BI interprets data using a month–day–year chain, all day–month–year formats will be disabled (and vice versa).
Date support in Textbox mode
Data Slicer now fully supports date type data columns in Textbox mode.
Show delimiter and show column name switches
Two new toggle switches enhance placeholder customization in Textbox mode: Show delimiter (default: ON) and Show column name (default: OFF, date columns only).
Changed features
Placeholder behavior
Placeholder handling has been made more dynamic and user-friendly. Custom placeholders always take precedence; otherwise the active input mask format is shown automatically.
Formatting settings panel
The date formatting UI has been streamlined. The “Use date format as placeholder” switch was removed (deprecated) in favor of automatic placeholder behavior, controllable via the “Show placeholder” toggle.
Fixed bugs
Clearing filters in Textbox mode
Improved compatibility with native Power BI buttons, including the “Clear all slicers” action, across Textbox and Interval modes.
Other changes
- Enhanced overall performance and reliability (solved race conditions where pages with >20 Data Slicer visual instances sometimes cleared out unapplied user input).
- Minor UI refinements for consistency across settings panels.
This release brings powerful new date format customization, smarter mask compatibility, and an even more intuitive Textbox mode experience.
