I am having a heck of a time figuring this out. I am passing parameters the right way (followed some tutorials on web). And the .rdlc has corrent notation (expression) for my parameters as well (=Parameters!myparam1.Value) decalred using Report Window. The plan is to load the report after I click a button. But the error occurs right when its trying to setParameters. Here is the code : \[code\]private void button4_Click(object sender, EventArgs e){ ReportViewer reportViewer1 = new ReportViewer(); reportViewer1.LocalReport.ReportPath = "AddressLabelReport.rdlc"; reportViewer1.ProcessingMode = ProcessingMode.Local; reportViewer1.LocalReport.SetParameters(new ReportParameter[] { new ReportParameter ("myparam1", "my value1", false), new ReportParameter("myparam2", "my value2", false) }); reportViewer1.RefreshReport();}\[/code\]Here is the StackTrace : \[code\]Microsoft.Reporting.WinForms.LocalProcessingException was unhandled Message="An error occurred during local report processing." Source="Microsoft.ReportViewer.WinForms" StackTrace: at Microsoft.Reporting.WinForms.LocalReport.CompileReport() at Microsoft.Reporting.WinForms.LocalReport.SetParameters(IEnumerable`1 parameters) at TextBookLabelForm.Form1.button4_Click(Object sender, EventArgs e) in C:\Projects\TextBookLabelForm\TextBookLabelForm\Form1.cs:line 204 at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) at TextBookLabelForm.Program.Main() in C:\Projects\TextBookLabelForm\TextBookLabelForm\Program.cs:line 17 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()\[/code\]Any help is appriciated.
