What I have tried:

tring strExeFilePath = Assembly.GetExecutingAssembly().Location;
            string exeFolder = Path.GetDirectoryName(strExeFilePath);
            string reportPath = Path.Combine(exeFolder, "Report1.rdlc");

            string Shdate = dateTimePicker1.Value.ToString("M-dd-yyyy");
            string Shift = comboBox1.Text;

            LocalReport report = new LocalReport();
            report.ReportPath = "Report1.rdlc";
           // report.ReportPath = "N:\\ED\\BufferProductionReports\\BufferManPower\\BufferManPowerReport\\BufferManPowerReport\\Report1.rdlc";
        DataTable dataTable = GetData(); // Method to fetch data, replace with your actual data fetching logic

Click the Improve Question widget below your post and supply the exact error message.

122 parameters? That seems ... excessive.

Ed Ryan Alora 19-Jun-24 5:54am

Hi Dave,
I think i have a diff problem i stayed up late, i believe i have all the parameters correctly.
PS i don't really have much option they key in the form and they want to basically display the form in a PDF. I'm already tempted to just to screenshot and send as PDF if i cant get this going LOL.

anyway. is it possible that I'm screwing up or missing a step somewhere else?
my build action is Embeded resource, my Copy to output is always.
appreciate all the help. learning is very tiring..

Ed Ryan Alora 19-Jun-24 10:05am

Hi David,
i think it something else, i deleted. almost all the all the parameter on the rdlc report and left 4 parameters. and i get the same error. its almost like the rldc report is corrupted or the code cant find it.

Start by looking closely at any error messages you get: they contain a lot of information if you know how to read them. The syntax is generally pretty close to those for syntax errors, so this may help: How to Write Code to Solve a Problem, A Beginner's Guide Part 2: Syntax Errors[^]

If you don't get any errors or it doesn't, then try cutting the report in half: remove the last 61 parameters from the report (having backed up the original stiff first) and see if the error goes away. If it does, go back to the original and remove the first 62 parameters.
When you know which half is causing the problem, you can start fine tuning what you remove until the number of parameters (and the related data) is manageable.

Sorry, but we can't help you - we don't have access to your entered data, or your DB!

But ... from a user POV 123 text boxes on one page is ... umm ... unfriendly!

Quote:
One or more parameters required to run the report have not been specified

The problem is right there in the error message. The report is expecting a parameter you're not providing. After 123 parameters, there seems to be at least one that you haven't provided to the report.

C#

param[97] = new ReportParameter("PCUL2", TXPCU2.Text);
                                   ^
                                   |
                 Parameter name. The report is looking for these and
                 matching against the expected parameters.

So, either you're not supplying all the parameters the report is expecting, and/or you misspelled one or more parameter names.

You just have to match up the names in your parameter list with the names of the parameters in the report.

Are you confusing the fields on the report with parameters? I think you removed all the fields that show data on the report. The parameters are values you pass in to tell the report how to query/filter the data it's going to show. For example, an inventory by warehouse would have a bunch of fields for inventory items and a parameter would be which warehouse the report is showing data for.

Hi Dave,
its ok now appreciate all the response, I just created a new rdlc report. the only difference i did was setting the change the content action and copy to output folder to content and always from the very beginning.

seems to work now,
