I am trying to make an rdlc report with a subreport. Both reports are using their own dataset.
I have made my parent RDLC report, WOReportandSub.rdlc, and it works fine. I have a list and several textbox's placed on it. It is grouped on WONum.
I then made my subreport, WOLockOutSubReport.rdlc, on which I placed one table and selected fields from my dataset. I added a parameter to the report called WONum - integer.
Then back to the main report I placed a subReport from the toolbox and then right clicked on it and went to Subreport properties and typed in the name of my subreport exactly as it is in the project minus the .rdlc part. Visibility is set to Show. I added a Parameter called WONum and chose the value for it as my [WONum] column from my dataset. If I run just the subreport by itself I get an error that says WONum parameter is missing a value, which would be true since I didn't pass it a parameter and the Main Report didn't pass it one because I ran it by itself. So I guess I'm wondering how I get that main report to pass the variable to the subreport.
I have a winform with all my report buttons and the code to run this report is as follows:
The code for the subreportProcessing is as follows:
The error I get when I try to run the report is "An error occurred during local report processing. Value cannot be null. Parameter name: value." I'm not sure what this means because I don't have a parameter called value it's called WONum.
Anyway I'm sure the error is probably in this code to actually run the report, but I can't seem to figure out what is wrong. I don't pass a parameter to the Main RDLC - the fill query for the dataset is any records that have the PrintStatus column = 1. So it could be bringing up several WONum's. The query for the subreport's dataset fill is bringing up the data for the same WONum's.
Does anyone know what I'm doing wrong. I have been working on this for days and I would really appreciate any input :)
Thanks,
Stacy
