Empty pages in RDLC-Report

问题:

I have a rdlc report that conains a tablix, nothing other. The Tablix expands in horizontal direction to show days and in the vertical direction to show groups.

The tablix works as expected, as long as I set the width of the content area equal to the width of the tablix.

If I expand the content size to its fixed size (approximately PageWidth-PageBorders) and run the report, every second page is an empty page.
However the tablix only uses one page. Every odd page is absolutely empty. It seems that the tablix adds its horizontal expansion to the currently definied content width and calculates then the overflow.

The reportviewer Version is 3 (2010 Redistributable)

Does someone have a solution for this odd behaviour?

Update

If I export the report to excel, I see that there is on the right site of the tablix a column that is exactly as long as the generated items for the days. It seems realy to be a bug or a feature I don't see how to deactivate.
I also have tried to create the same construction from a table, and it resulted in the same problem, what not is astonishing, because the table is internally also a tablix.

Update 1

If I set the property "ConsumeContainerWhitespace" of the report to true, the above test version works. But if I place then other elements in the "white" area, the effect reocurrs.

回答1:

Setting the page-property ConsumeContainerWhitespace=true (in the properties dialog, F4) has helped. However it was anyhow tricky to build the report correct. At the begining it worked only if I added all extra content to the page-header and footer. But this was not acceptable. After a lot of trying, I succeed in making the report as desired. However I don't really understand the logic behind.

I have in mind that I already have done such reports (growing in both directions, horizontally and vertically together) without any problems and I don't know what is difference to this report here. For this report, it's definitively reproducable that the ConsumeContainerWhitespace-property makes the difference. But why this never happens to me for similar reports I have done, I don't know. Also I don't know why I had first to circle around before the layout-engine accepted my design.

The best way to solved this problem is, for example for an A4 page where Width=21 cm and Height=29.7 cm

Now Margin Left=1 cm and Right=1 cm so you are having a usable width of 19 cm.

When you have understand this basic calculation that means your problem is solved. You can set up the report page size properties by right clicking on the report property => pagesetup.

回答3:

Check the "body" size, try to make it as wide and height as your real paper size but reduce only the margins.

回答4:

There is a confusion there on the page design. Developers would think the report being designed is WYSIWYG, but actually it's NOT!! Microsoft reportviewer will take your designed page as the content!! and append the margins defined on the outside of your page, and turn out that your page can never fit in to one page!!

So, when you design a new report, focus on the content area, the client area, including your headers and footers, and allow margins to be appended on your outer border.

回答5:

the solution is simple ConsumeContainerWhiteSpace=True (you find this in the property window for "report") you set the paper size in the main menu/ report/report properties for example to "A4" and then you check that paper size is larger then body + header + footer + margins.

回答6:

I was having the same issue until I played with the report body's height and width. :)

回答7:

I have meet this problem recently.

The root cause may be:
your report's body has some blank upside report Footer or somewhere else.
The solution is :
1, click the report body
2, go to the property window, you will see the body size property
3, check the body size, you may find a strange number like 9.6654in,1.5625in.
that means you have some blank upside the Footer, modify the height or width size till there is no blank you can see.

回答8:

Please select "Report" in the object selector at the top of the window. and make the ConsumeContainerWhiteSpace = true if the also same problem persist then, your rdlc report size should be less than your report body.!

回答9:

You need set report width property to actual print page width. In my case 6 inches helped.

回答10:

You need to make sure your RDLC Report have :

1. ConsumeContainerWhiteSpace = true (open by click F4)
2. Report Body Size <= Page Size+margin Size. (open by Ctrl + Alt + D)

回答11:

I was working with an RDLC report that was printing an extra blank page. I tried all the usual tricks, and everything I could think of, until I realized the problem was caused by an extra amount of visible whitespace in the right margin area of the report. One of the objects in the report (a "Rectangle") was a single pixel or two too wide, and this prevented resizing the visible space of the report. Once I removed all the extra width, the report started printing with the expected number of pages.

Visual Studio 2017 (15.7.5) + Microsoft Rdlc Report Designer extension (v14.2)

回答12:

Page Footer may cause the problem too. So if you have one, it's better to place it as near as possible to the main content. In this case you don't need to set the Body.Height property.

回答13:

My 4x2 inch label was printing 3 extra pages for a one page report.

To fix it, I reduced the Body.Size attribute to be same or smaller than the Report.PageSize minus the summed respective Report.Margins.

回答14:

Try this one,

Just make sure that all Data the needed is in the report, Then Select the Table or the Matrix and make it squeeze to the left and if needed to the Top Left Corner until your white Page Problem is Done.

But make sure that the cells are squeezed in the right manner, Be gentle (I hope you got it !!)

Ok, Bye

Or you can just graphically resize your report design, to the exact bottom of the last report control or label.

Or add a footer section to create some space.
