Hello Support-Team,
in the WebReportDesigner, the Edit-Window shows "undefined" for the FieldNames, when selected a second Time.
This is also reproduceable in the demo application: https://demos.telerik.com/reporting/designer.
(see Screenshot in attached Files)
Steps to repoduce:
1. Open the Edit-Window for a TextBox (with a DataSource)
2. Select the DataSource-Entry.
3. Select some other Entry, e.g. "Report Parameters"
4. Select the DataSource-Entry.
Best regards
