I have a ReportViewer in my WinForms application to show some data in the form of a Telerik Report. I also have some textboxes, which will update the Report when the user leaves the textbox and the text has been changed.
After leaving a textbox, the ReportViewer gets the focus on itself. So I'm using UpdateUI event. To test if it gets fired, I just call a MessageBox:
To my surprise, the message box gets called 8 times. First, I thought the "_Leave()" event must have an error. But the Leave event is only triggered once (as expected). It's only the UpdateUI event which is triggered multiple times. Everything else is working as expected. Is this a known bug or can anyone please provide me some help?
