在编辑SSRS文档时，最好先在设计面上(Visual Studio 2012显示，但可以在其他版本中完成)进行计算。

下面红圈内的数字对应以下步骤:

In the design surface, sometimes the editor will create a page which is larger than the actual controls; hence the ghost area being printed. Resize to the controls. Visually look at the width/height and see if you can't bring in the page on the design surface to size it to the space actually needed by the controls and no more. Then try to create a PDF and see if that fixes it. If #3 does not resolve the issue, then there are controls requiring too much of the actual page size and going over in either length/width. So one will need to make the size of the controls smaller to accommodate a smaller page size.

此外，在某些情况下，可以通过将ConsumeContainerWhitespace设置为true来更改报表页面的属性，从而自动使用这些空间。

If your report includes a subreport, the width of the subreport could push the boundaries of the body if subreport and hierarchy are allowed to grow. I had a similar problem arise with a subreport that could be placed in a cell (spanning 2 columns). It looked like the span could contain it in the designer and it rendered fine in a winform or a browser and, originally, it could generate printer output (or pdf file) without spilling over onto excess pages. Then, after changing some other column widths (and without exceeding the body width plus margins), the winform and browser renderings looked still looked fine but when the output (printer or pdf) was generated, it grew past the margins and wrote the right side of each page as a 2nd (4th, etc.) page. I could eliminate my problem by increasing colspan where the subreport was placed. Whether or not you're using subreports, if you have page spillover and your body design fits within the margins of the page, look for something allowed to grow that pushes the width of the body out.

除了目前为止最常见的问题，我还看到了另外两种可能性:

使用+连接文本。你应该用&代替。 超出指定文本框宽度的文本。因此，如果你的文本框只容纳30个字符，而你试图在那里塞300个字符，你可能会以额外的页面结束。

我通过以下方法解决了这个问题。(使用最新版本的报表生成器)

步骤1)。进入“查看”选项卡 步骤2)。选中“属性”复选框 步骤3)。单击报告主体内部(它将更新属性选项卡中的值) 步骤4)。不要拿这里的宽度 步骤5)。右键单击报表外的灰色区域，然后单击报表属性 步骤6)。将你的左右边距加上你的身体宽度(如果它等于10，那么你的宽度为11) 步骤7)。保存

我最近继承了一个报告，需要对其进行一些更改。在遵循上述所有建议之后，它并没有帮助。这份报告历史上多了这一页，没人知道为什么。

我右键点击表格并选择属性。有一个复选框表示在后面添加换行符。删除后，它打印在一页现在。

在报告(myReport.rdlc)的属性选项卡上，将“Keep Together”属性更改为False。我一直在这个问题上挣扎了一段时间，这似乎解决了我的问题。
