Is anyone monitoring this forum?

Reply Contact

I posted a problem a week ago and no one has answered my post. My project is on hold until someone from C1 can answer my question regarding using a business object created in .net as a record source. Crystal Reports can handle this situation easily. Why can't C1 reports?

Here is my original post:

I am trying to create a c1Report based on a business object.

I have tried the following:

dim open_timesheets as list(of Open_Timesheets) = Open_TimesheetsDB.GetList 'populates a list of timesheets

dim rs as IC1ReportRecordset = ctype(open_timesheets,IC1ReportRecordset)

c1report1.datasource.recordset = rs

I receive the following error at the dim statement:

Unable to cast object of type system.collections.generic.list 'ST_Classes.Open_Timesheets' to type 'C1.Win.C1Report.UCreportRecordset'

How can I base my report on a dataobject like this? I have tried everything I could think of to make this work... Examples would be fantastic! Thanks in advance! Ken

IC1ReportRecordset is interface. You can't convert object to interface if object doesn't
implement this interface.
Try to change your code, it might look like that:

dim open_timesheets as list(of Open_Timesheets) = Open_TimesheetsDB.GetList 'populates
a list of timesheets
c1report1.datasource.recordset = open_timesheets

open_timesheets can be one of the next:

- DataView instance;
- DataTable instance;
- object implementing IC1ReportRecordset;
- object implementing ITypedList and IBindingList interfaces;
- object implementing IListSource interface.
