Report Book parameter view states collapsing on refresh.

[James]

Hello,

We have recent upgraded from Reporting Q2 2015 SP1 to Reporting R1 2017 SP2 11.0.17.406 and we are having an issue with report books. Anything that causes a refresh causes all of the parameter viewstates to collapse. If we fill them with pre-saved values and attempt to display the report book, they also collapse and rendering the book fails because no parameters can now be found. Not experiencing this issue with single reports, only report books.

Is there somewhere i should be looking specifically to address this? Using VS2017's debugger did not help much, only to show that the viewstates are gone before the first parameter is ever retrieved. Any insight would be most appreciated.

Hi James,

With ReportBooks, if the Name and Type of two (or more) parameters from different reports are the same, then they are considered equivalent and are displayed as a single parameter in the parameters area.
You can control parameter merging via the Mergeable boolean property of the ReportParameter class. The default value of the Mergeable property is true - Report Book Parameters.

If the issue is different test to compare your settings with those provided in ReportBook report located in Telerik Reporting directory: [installation directory]\Telerik\Reporting [version]\Examples\CSharp(VB)\ReportLibrary\ReportBook.

If you use HTML5 Report Viewer and custom parameters editors test switching to the default ones.

In order to provide you more accurate suggestions, we would need to check the problematic reports and the code you apply to modify them if any. You can attach this information in a support ticket.
