Hello Jeremy,

This feature is currently not in our plans for the next release, I am afraid Besides following the status of this item, you may have a look at the Roadmaps for Telerik Reporting – Telerik & Kendo UI Roadmaps page for more information on what features are planned for the incoming releases.

As a workaround, I would recommend creating separate UI controls, outside of the report viewer, where you will have full control over what control should be displayed on the page and what should remain hidden, the selected values can then be passed to the report's parameters through code.

For example, if you are using the HTML5 Report Viewer, you may visit the Sending Values to Report Parameters from outside HTML5 ReportViewer - Telerik Reporting article.

Alternatively, you may implement custom UI controls inside the report viewer for the report parameters - Creating and Using Custom Parameter Editors in HTML5 ReportViewer - Telerik Reporting. This will allow you to control the visibility of the items through JS/CSS.

I hope that the suggested workarounds will work for your needs.

Regards,
Dimitar

To make clear the feature request for the community: It is to be able to hide/disable a report parameter based on other parameter's value. Cascading parameters that target the visibility of the child parameter. I will alter the original title "Report filter hide" to "Cascading report parameter visibility".
