Large gaps in data SSRS - reporting-services

I am having an issue in SSRS where my data is showing huge gaps between rows. The dataset is trimmed and has no white spaces. Consume whitespace is also set to true. In the picture below, the row above the top one has an even bigger space between the row.
Any idea what's going on here?

I was able to figure out what the issue was:
My report included the Details grouping, even though I only wanted the Parent grouping to display. I believe this made the report show large white space gaps, as those would be detail rows that would otherwise be in the report, if it was not grouped by the first Parent row.
Therefore, I deleted the Details grouping under Row Groups which resolved my issue.

Keep rows together on the same page in ReportViewer (RDLC)

I've created a RDLC report that looks like this:
Basically data is grouped first by Category and then by Subcategory. Then, as you can see from the screenshot, the Details group has multiple rows, since I want to organize data in that "grid-like" layout.
Now, the problem is that I want the following pagination behavior:
The first row of the table ([Category]) should never have a page break after it, in other words: it should always stay together with the second row ([Subcategory])
Same with the second row ([Subcategory]): I never want a page break after it, it should always appear together with the first block of detail rows
The details rows should never be split into multiple pages, so I want all the 9 table rows in the details group to always appear together on the same page
I've been playing around for several hours with the KeepTogether and KeepWithGroup properties of the Row and Column groups, but they mostly seem to have no effect whatsoever. How should I set them to achieve the behavior I want?

SSRS Reporting - How to repeat a series of different elements based on a parameter

I have a report with one input parameter, and based on that input, the report will have 1-3 different categories present. My issue is the report layout consists of the following elements: A header, 3 tables, and a bar chart.
What I am trying to accomplish is to repeat the above layout with ONLY categories available to the input parameter without leaving unnecessary whitespace. I've tried to achieve this by copying and pasting the layout three times and hiding the elements if the category does not exist. This works partially as I'm left with blank pages.
Instead of filling the report with a bunch of tables, try adding rows to the 1st table, adding a rectangle in that row, and adding a sub-report in the rectangle. Set the visibility of the rectangle instead of your 2 tables. This will ensure that there are no unnecessary white spaces.
Adding more than 1 table to a report has almost always ruined the layout of my reports. I've always added sub-reports instead. Even if you don't want to add a rectangle, just add a sub-report in a new row of your ONE table and that makes it a lot easier to deal with.

SSRS - Adding empty cells under a tablix to fill empty spaces on the page (if any)

I work with ssrs with a dynamic row data in matrix/tablix. There is possibility when I have more than one page (say it two pages) where the data just fill half of the second page and leave a blank space below (half page blank space on the second page). How is the way to fill this blank space with empty rows? (whether rendering empty rows in the tablix, or inserting background image, or anything. I don't have any solution yet as it is dynamic data with many possibilities of the blank space size on the page)
Unfortunately there aren't any settings in the reporter that support this behavior. There are however several workarounds you could use to get the wanted result.
[1]
You could determine the amount of rows that fit on the first page and on the second page, just in case you have items above the
table on the first page. Before you send the datasource to the
reporter count the total rows and check if it exceeds the first page.
Then calculate the number of rows missing to fill an entire second
page (or third/fourth... if you ever get more data). Finally you add
empty rows/objects at the end of your datasource, which will of cource
cause the pages to be filled to the end.
As was pointed out before, this solution is only possible when working
with fixed row heights. If certain columns can have multi-line cells
then these could be checked as well and taken in account when
calculating the number of rows being displayed on the page. This makes
it slightly more complicated but is still a valid solution if you can
predict which columns might be troublesome.
[2]
A second solution would be to hide the table borders and place the table inside a rectangle that spans the maximum size of the
page. The borders of this rectangle can be used to display the table
outer borders and columns can be displayed by adding lines inside the
rectangle. This will cause the columns to fill the last page of the
report automatically. Unfortunately this isn't a solution to display
horizontal grid lines.
[3]
A third approach is adding an extra table directly below your table
with the same size of columns. Using the same method as from the first
solution you could fill the second table to represent the empty rows.
You'll probably have the same issue as with the first solution when
dealing with multi-line rows though.
I believe solution [1] and [3] will offer the most exact solution, if you're willing to do the math. If you don't want any horizontal lines then I suggest using approach [2].
Using an image to overlay the borders is of course another option but then you'll have the same issues when dealing with the multi-line rows. If you plan on working with fixed row heights, where you leave space for multi-line cells then this is becomes a valid approach but so does solutions [1] and [3].
Update:
If you only need the filled pages for printing you could make sure you add enough empty rows to fill at least the entire last page, these may go to a new page (1 new page, not 2... you can use a simple calculated guess for this) and exclude the last page when printing.

Empty page when hiding tablix

I've got a number of tablixes and they hide/show expressions.
If we run the report for a particular dataset, the first tablix is shown on the first page and the data ends pretty much on the last line of the page.
The second tablix is hidden in this particular scenario but since I have left about 1cm gap between tablixes, this causes a new empty page to be created. Is there any way of removing this gap?
Move the tablix's closer together (basically remove as much whitespace as you can)
If you need more space when you are showing the tablix - add a row to the top of the tablix and set its visibility to false.
This is often caused by the feature of ssrs preserving whitespace around objects that are hidden
Check for the page breaks in the tablix properties. It may be there which is causing this.

SSRS - RDLC Tablix Rows will not split across pages

I have a tablix with two columns of data (the section name and the section text). The section text has grown so large for some sections that the row representing the section takes up 2/3 or more of the page. THe report prints fine until on of these large rows would have to split over the end of a page and continue on the next page. In this case, and only in this case, the rows leaves large amounts of white space on current page and start on the next page (as if it had a page break before it)
I have already set the Tablix General Property "keep together on one page if possible" to true and all the other page break options for the tablix and row groups to false, to no avail.
Does anyone know of a trick or work around to make the large rows split over pages??
Setting Keep together on one page if possible to true/checked will cause SSRS to attempt to keep the row on one page, which means if the data spans across page breaks it will move that row to start on a new page so that it can be seen on one page, which would introduce white space where the row would be if the table was contiguous. So you need this setting set to False/Unchecked.
Next, ensure that the row group proeprty Keep together is set to False. This can't be accessed through the normal dialog box. If you don't have the properties pane showing in BIDS, then pressing F4 will bring this pane up. Select the row group(s), and ensure the property is appropriately set.
Also make sure that the text boxes inside the tablix are also set to KeepTogether=False. This will fix the problem.
