Recently, I need to explain the report to students. NET is naturally the choice of rdlc.
Because Visual Studio 2013 is used in the student competition, I installed Visual Studio 2013 in my notebook (usually 2010). After installation, follow the instructions in the official document to drag the reportviewer control to a form, but it is strange that the "intelligent tag panel" mentioned in the official document is not displayed, and there is no control shadow on the interface, reportviewer appears in the component area.
After several minutes of thinking and trying, I reset the toolbox of 2013, and the reportviewer control returned to the Report Group. It also changed its appearance and version to 11.0, then drag the control to view the desired result.
In a simple summary, it should be because 2013 is installed for compatibility consideration. It reads the 2010 toolkit, and the 10.0 reportviewer replaces the 11.0 reportviewer, while 2013 does not support the 10.0 reportviewer, this problem is caused.
The two versions of different reportviewer icons are attached, with 10.0 on the left and 11.0 on the right. If you see the icon on the left in the vs2013 toolbox, you can consider how to handle it.
