Hide space between elements of a report

问题

I have one report with various subreports. These subreports are within a table cell. When the subreport doesn't have any data available, I hide the components (tables, textbox, charts) in that subreport. However, this creates some blank space and I need to eliminate this space.

I already used the properties ConsumeContainerWhiteSpace and KeepTogether, but the blank space is still there.

Any suggestions to remove the blank space?

To hide or show an entire row based on another reports results will be difficult, if not impossible. You will need to get this data in your parent report somehow.

I would create a cut down version of your subreport's query that returns row count for every subreport, but within the parent report. Might look like this:

UserID   RecordCount
  Abby       3
  Bob        0
  Carl       1

If you are using SSRS 2008r2 you can then use a lookup function to set row visibility. For example the row visibility expression might be

=IIF(Lookup(Fields!UserID.Value,
       Fields!UserID.Value,
       Fields!RecordCount.Value,
       "LookupDatasetName") > 0,
    false,
    true)

If an earlier version of SSRS, then join that dataset into the dataset for your table.
