I want to create a website project with asp.net.
And now I want to implement a ReportViewer in my project.
But when I drag and drop a reportviewer from the toolbox to the
MainContent of a masterpage, i get an error shown in the attached screenshot.
I can ignore this error and click OK, but when I want to set a ReportSource
there comes another warning.
Perhaps it is related to each other.
Is it not possible to drop a reportviewer to a MainContent of a masterpage?
