We are using the reportdesigner in our web application.
After we upgraded from version 18.1.6 to 19.1.6 we experience performance issues using the reportdesigner with a large context.
I have included a test project with an example and a video where you can see that memory consumption of chrome browser is increasing very fast.
It seems to happen when navigating the datasource and selecting the datamembers.
With this fix, we provided the client-side DevExpress.Analytics.Widgets.TreeList.LoadChildItemsForCollapsedNodes option. Disable this option in the client-side code when the Web Report Designer is initialized to avoid loading fields for collapsed items of the Field List.
As a side effect, after disabling this option, the expand buttons will be displayed for all data sources and collections in the Field List (even if this data source / collection does not have inner fields).Show all comments
