We use Microsoft’s ReportViewer for our reporting needs. It isn’t the most elegant but it does the job.
Recently I needed to display a table on a report with an empty row if there was no data in the data source. This is a visual indicator on the report that there is no data for that item. Here are the instructions on the way that I found to do this.
1. Right click on the data row in the table
2. Add a new row below it, outside of the group.
3. Right click on the row and select row visibility
4. Click the radio button for “Show or hide based on expression”
5. Enter code similar to the following as the expression:
=IIF(Sum(Fields!Id.Value, "DataSetName") > 0, true, false)
This will show the row empty if there is no data and hide it if there is data. Not very elegant but will do the job.
