Blank Page for RDLC report Drilling

Blank Page for RDLC report Drilling

When you modify the REPORT query conditions, the drilling page suddenly becomes blank and cannot be understood. I studied the information for one afternoon and one night, and checked the information. Many of the information on the Internet is the ConsumeConteinerWhitespa of the report.Ce = True and the SIZE of the Set BODY cannot be greater than the SIZE of the report. I asked my colleague to say that there are too many report parameters. I was about to modify it into a parameter, but when deleting the parameter, I thought that when I was just drilling, the data was not displayed because the parameters were incorrect. I set allow NULL and allow NULL to display the data. I checked that a new parameter was not set, it is displayed immediately after it is set up, so I will take the problem seriously in the future.

Another problem is the RDLC report. I use the same SQL statement. The field names and results are the same, but one is a table and the other is a view. However, if the table is assigned a value, it can be displayed, the view won't work, and the chart cannot be displayed, but it won't work out in a few days. My colleague helped solve the problem. The FIELD bound to the data source, After dragging the FIELD, is SUM (FIELD. VALUE), other reports are okay, and the same is true, but this report does not work. My colleague's solution is to remove SUM and only bind fields, so that we can, now my head is a little stiff.
