can not display the linked field value table + ReportViewer
I want display data of table. And I can't display instead of the fields-id their value from the table to which they refer.
I add new item - Reportint-> Report (*.rdcl) and than add on the web form ReportViewer. VS dispayed wizard and I add new DataSet where choise my business method for select data.
I have table Inhabitans it contain FacultyID field, but I want see Value from linked table where Inhabitans.FacultyID == Faculty.FacultyID.
public List<Inhabitant> SelectAllWithoutParameters()
{
using (DataContext dc = Infrastructure.DataContext)
{
DataLoadOptions options = new DataLoadOptions();
options.LoadWith<Inhabitant>(u => u.Faculty);
dc.LoadOptions = options;
List<Inhabitant> inhs = dc.GetTable<Inhabitant>().OrderBy(u => u.FullName).ToList();
return inhs;
}
}
Click Insert - 开发者_开发百科New Table. I can choose all fields from Inhabitant, but not from Faculty.
How to solve this problem
I don't know anything about rdcl reports, but I would create a new class to project the data into, something like InhabitantReport.
Then you just change this line:
List<Inhabitant> inhs = dc.GetTable<Inhabitant>().OrderBy(u => u.FullName).ToList();
to something like this:
List<InhabitantReport> inhs = dc.GetTable<Inhabitant>().OrderBy(u => u.FullName).Select(r=>new InhabitantReport()
{
//Populate data.
}).ToList();
