For my multiple energy meter project I have several windows and reports. The user should select the date range of interest on the navigation bar and windows opened should report data based on the selected date range. This allows easy comparison of energy use across multiple meters.

How can I link the tag history Start Date Binding and End Date Binding properties on each window to the components on the navigation bar?

Any other ideas?

Create a client tag for each and then set them to the selected values.  
This way it is workstation independent as well.

Cool! I hadn’t used one before.

For anyone else: see [docs.inductiveautomation.com:84 … ndirection](https://docs.inductiveautomation.com:8443/display/DOC/Using+Client+Tags+for+Indirection).

Also note that the property binding to the calendar control has to have the “bidirectional” setting enabled so that selecting a date updates the client tag.

Many thanks.
