我使用Visual Studio 2015社区报告查看器版本12来显示我的c#项目中的rdlc报告.
这是正常的A4页面报告
它适用于windows xp,vista,win 7在客户端PC上,但是当在Windows 10 64 bit上安装相同的应用程序时,我面临如下问题
正如您在上面的图像中看到的那样,右侧和底侧都有不必要的边距,字体大小也会减少.但是当我将报告导出为PDF时,生成的PDF中没有问题与我设计的报告相同.
我试过什么：
>我安装了MICROSOFT®REISORTVIEWER 2015 RUNTIME
https://www.microsoft.com/en-us/download/details.aspx?id=45496
>已安装的Microsoft®SQLServer®2014Feature Pack(SQL的系统CLR类型)
服务器2014)
>尝试使用以下代码将RDLC直接导出到打印机

但它的印刷也与上述相同
相同的应用程序在我的PC上使用Windows 10 64位运行但在部署在具有Windows 10 64位的客户端PC上后无法运行
在客户端PC .Net 4.0框架,SQL Server 2008,Windows 10 64位安装
如何解决它.
解决方法:
我不认为这个问题与安装的任何工具或仅特别是Windows 10 64位有关.
相反,正如jdweng& amp; amp; amp; amp; amp; amp; amp; amp; amp; amp; Reza Aghaei.更具体地说,高DPI设备.
不确定您是否注意到,但您上传的图像都是不同的像素,而低像素的图像显示报告的正确呈现.这可以说是由于高DPI引起的扩展问题.
现在,有很多文章,帖子和问题.但是,为受害者提供某种正确方向的非常接近的是Microsoft支持门户网站上的那个,它似乎很少有可能的解决方案(是的,复数)和为这种行为提供的解决方法(再次,复数).
你可以在这里找到这篇文章：https://support.microsoft.com/en-au/help/3025083/windows-scaling-issues-for-high-dpi-devices
我相信,我在下面引用的解决方法应该可以帮助你解决时间问题.
Change application properties
In Explorer or on the Start menu, right-click the application name, select Properties, select the Compatibility tab, and then select the Disable display scaling on high DPI settings check box.
Note:
In Windows 10 Version 1703 and later version of Windows, the text of the Disable display scaling on high DPI settings option is changed to Override high DPI scaling behavior, scaling performed by: Application.
