Issues Setting RDLC Datasource to Object

Question

Background:

I\'ve been tasked with converting an Access database application to ASP.Net C# MVC. This is my first MVC application.

There are

Answer 1

Visual Studio does not recognize your class when you use only public members. When you use getter and setter instead, you can see your class when you choose your datasource.

There are some other wizards in Visual Studio that do not work with public members.

Answer 2

I was able to add an object as a datasource in VS 2017 without the report Wizard. [Winforms app using c#] [PS I am a NOOB, so there is going to be mistakes etc, but i hope this helps with giving a direction.] steps I used:

part A 1. create an object that represents the data e.g.: object / model class in my case it is an appointment object

 class FutureVisitsModel
    {
        public DateTime StartDate {get; set;}
        public string Client_Id { get; set; }
        public string Treatment_Desc { get; set; }
        public string Service_Code { get; set; }

        public FutureVisitsModel()
        {
            DateTime startdate = StartDate;
            String clinetid = Client_Id;
            String treatmentdesc = Treatment_Desc;
            String serviceCode = Service_Code;
        }
    }

Part B: create report 2. Added report to solution: right clicked solution, select add new item and chose report enter image description here 3. opened the blank report 4. from toolbox, drag n drop a table to the report 5. a dialogue opens to choose a data source 6. select the object from your solution [ ypu will be looking for the class you created in part A

Part C: create a report viewer form 7. on solution explorer create a new form "formRptViewer" 8. open the form and add report viewer control 9. If you dont have the control in your tool box, you will need to install the report viewer package from nugget or install via package manger console. webforms version : Install-Package Microsoft.ReportingServices.ReportViewerControl.WebForms winforms version: Install-Package Microsoft.ReportingServices.ReportViewerControl.WinForms

9.1 set the control of the report viewer to public in solution explorer click the dropdown next to your formRptViewer to see the files that make up the form edit this file: formRptViewer.Designer.cs change the controll pf the reprtviewer to public public Microsoft.Reporting.WinForms.ReportViewer ReportViewer1;

part D: create a datatable and send it to report 10. create a datatable DataTable dataTableFutureVisits = new DataTable(); [you will need to fill the datatable with y our own data] 11. add using statement using Microsoft.Reporting.WinForms; 12. set the data source and create a new instance of the report viewer

ReportDataSource rs = new ReportDataSource();
            rs.Name = "DataSet1";
            rs.Value = dataTableFutureVisits;
            FormRptViewer frm = new FormRptViewer();
            frm.ReportViewer1.LocalReport.DataSources.Clear();
            frm.ReportViewer1.LocalReport.DataSources.Add(rs);
            frm.ReportViewer1.LocalReport.ReportEmbeddedResource = "ChiroRecallList.RptFutureVisits.rdlc";
            // name the report with date
            frm.ReportViewer1.LocalReport.DisplayName = "Your File Name Goes Here" + "_" + DateTime.Now.ToString("yyyyMMdd HH:mm");
            frm.ShowDialog();

Part E: updating the report: adding columns to the datatable and show them in the report [ also forks for removing a column]

1. add a column to your datatable
2. change your object class to reflect the data [ as in part A ]
3. open the report and delete the dataset [not data source ]
4. in solution explorer: there is a properties dropdown expand that
5. expand the datasources folder

6. delete the data source that is named after your model screen shot

7. clean and rebuild solution screenshot

8. open the report and right click on your datasource and add new dataset screen shot

Answer 3

I've just come across this same issue when trying to create RDLC reports in an ASP.NET MVC project in Visual Studio 2017, so I'm adding this as a separate answer to make it clear this is still an issue at January 2018.

My solution consisted of a C# library project and an MVC client project.

Adding reports (by choosing at add a new item, then choosing a Report Wizard item) in the C# library project brings up the Report Wizard with the Data Source Configuration Wizard (where I can choose whether to use a Database, Service or an Object as the datasource) modally on top of it:

Whereas, choosing to add a new report wizard item in the MVC project just brought up the Report Wizard without the Data Source Configuration Wizard:

I tried adding business object classes into my MVC project, recompiling it and then adding a Report to the MVC Project again, but I still got the second screenshot, so it seems like you just don't get the Data Source Configuration Wizard when adding to MVC projects for some reason.

Answer 4

Set your objects under the same namespace but on a different project which you then reference on your UI project.

Also try implementing INotifyPropertyChanged.

Answer 5

1. Make sure the classes are in the same namespace as the application.
2. Try building the application before you create the report
3. Start the report wizard. Under DataSouce select the name of your web application.
4. Under Available Datasets you should see what Visual Studio interprets to be your "Select Method". If all is well, this should be TurnArounds.

You may need to put the class file in the App_Data or App_Code folder, but I am not certain.

This might also help.
