ReportParameter Exception Error

Question

Hi I already developed a website with reporting function and it working without any problem. Now I want develop a Windows Form App and C# with reporting function. This is what I did:

private void print_Load(object sender, EventArgs e)
    {
        rptViewer.Reset();
        DataTable dt = getData("2");
        ReportDataSource rds = new ReportDataSource("DataSet1", dt);
        rptViewer.LocalReport.DataSources.Add(rds);
        rptViewer.LocalReport.ReportPath = @"PAL\Report1.rdlc";
        ReportParameter[] rptParams = new ReportParameter[] {
        new ReportParameter("invoiceId","2")
        };
        rptViewer.LocalReport.SetParameters(rptParams);
        rptViewer.LocalReport.Refresh();
        this.rptViewer.RefreshReport();
    }

And another function for filling DataTable:

private DataTable getData(string id)
    {
        string[] dataName = new string[1];
        dataName[0] = "@invoiceId";
        string[] dataValue = new string[1];
        dataValue[0] = id;
        DataTable dt = new DataTable();
        dt = _cls.FillDataTable("procBasket", dataName, dataValue);
        return dt;
    }

But When I run the program, VS throw an error as like this:
and It seems VS can't found report path and throw below exception:

Exception:Thrown: "Could not find a part of the path 'C:\Users\BNS\Documents\Visual Studio 2013\Projects\nickSell\nickSell\bin\Debug\PAL\Report1.rdlc'." (System.IO.DirectoryNotFoundException) A System.IO.DirectoryNotFoundException was thrown: "Could not find a part of the path 'C:\Users\BNS\Documents\Visual Studio 2013\Projects\nickSell\nickSell\bin\Debug\PAL\Report1.rdlc'."

I do something for path but error still is exists :(

string exeFolder = Path.GetDirectoryName(Application.ExecutablePath);
string reportPath = Path.Combine(exeFolder, @"PAL\Report1.rdlc");
rptViewer.LocalReport.ReportPath = reportPath;

at the end this is my solution tree view

and print winform path that has reportview control is like this:

Answer 1

Try Application.StartUp instead

Change this,

string exeFolder = Path.GetDirectoryName(Application.ExecutablePath);

into

string exeFolder = Application.StartUp;

Edit: according to our chat, the problem is that the report path is actually located in the parent of parent folder of the solution executable. That is why the error occurs.

In order to correct the error, simply go to the report folder by doing:

string dir = Directory.GetParent(Application.StartupPath).FullName; 
dir = Directory.GetParent(dir).FullName; //get parent of parent folder
string reportPath = Path.Combine(dir , @"PAL\Report1.rdlc"); //then do this
rptViewer.LocalReport.ReportPath = reportPath;    

This way, the report path points to the correct file in the correct folder. The key to solve this issue is to get the folder right.
