Dim str, str1 As String
Dim bookno As Integer

str1 = "Select bookno from bookmaster where bookname = '" + cmbName.Text + "'"
cmd = New OleDbCommand(str1, cn)
dr = cmd.ExecuteReader

If dr.HasRows Then
While dr.Read
bookno = dr(0).ToString
End While
End If

Dim l As New BookIssueDetail //this is my report name

str = "select BookIssueDetail.grno,StudentMaster.StudentName,Boo kIssueDetail.BookNo,BookIssueDetail.IssueDate from BookIssueDetail inner join studentmaster on studentmaster.grno=BookIssueDetail.grno where BookIssueDetail.bookno =" + bookno.ToString


da = New OleDbDataAdapter(str, cn)

Try to set the specific table to the report instead of setting dataset as the datasource.

Eg:
l.SetDataSource(ds.Tables("BookIssueDetail"))
