对我来说，问题是SSRS故意对待你的空白，就好像你想让它得到尊重一样:

和空白一样，确保没有右边距。

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.

你有没有看一下你的报告右边是否有空白处?如果是这样，您可以将它拖回报表的末尾，然后将报表背景拖回相同的位置。

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

I have worked with SSRS for over 10 years and the answers above are the go to answers. BUT. If nothing works, and you are completely stuffed....remove items from the report until the problem goes away. Once you have identified which row or report item is causing the problem, put it inside a rectangle container. That's it. Has helped us many many times! Extra pages are mostly caused by report items flowing over the right margin. When all else fails, putting things inside a rectangle or an empty rectangle to the right of an item, can stop this from happening. Good luck out there!
