    Hi, we use web api call a report project library and show the report in html report view, I found a issue, sometimes when I click the preview button, the parameter area on the right will auto hide, if you click the top parameter area button, it will show again. I can't find the reason, it looks like happen sometimes. I have already update the report to 2016 SP1. How can I resolve this issue?

    Hi Henry,

    Similar issue on initial loading of the viewer was present in previous versions due to the asynchronous loading of CSS files. Loading all required Telerik Kendo UI CSS files, the viewer's CSS file in the head of the page resolves the issue. Also the fix added in the latest releases of Telerik Reporting should handle the issue without additional settings.

    Inspect the page and any external CSS and JS files that may include rules, functionality that hides the DIV of the parameters' area.

    Since we are not aware of such problem in the latest releases, we will need a log file by Fiddler and a demo project that illustrates the problem. Include also details about the tested browsers.


    Do you want to have your say when we set our development plans? Do you want to know when a feature you care about is added or when a bug fixed? Explore the Telerik Feedback Portal and vote to affect the priority of the items

    I add the link css and javascript files as project local files, the issues don't show again, I think the issue is fixed. If web use link from other cdn website, the async loading may cause this issue.
