i have a project with VB.net 2010 / Entity framework 4. I have 2 tables :
Table1 Table2 id1 id2 name value city date id1
i want to display on report : value , date , Name
i can make the query to get records that i need to display on report ,
with report wizard , i have created the crystal report ( CrystalReport1.rpt ) with fields from both 2 tables : value date name.
Now , this is my code :
Dim report As New ReportDocument report.Load("c:Crystalreport1.rpt" ) Dim context As New myEntities Dim query = From t1 In context.table2 where ....conditions Select t1.value , t1.date , t1.table1.nameu3000 report.SetDataSource(query.ToList) Form1.CrystalReportViewer1.ReportSource = report
when the report is open , the columns value and date are filled with correct values , but the column name is empty.
What can i do ?
