Using WebReport in asp.net WebAPI and JQuery

edited July 2014 in FastReport .NET
I'm trying to use fastreport.net as WebAPI and can be loaded via jquery. It works perfectly, as in asp.net webforms. But in multiple tabs of report, only first report is shown with data and the other tab is shown without data. Seems that the other tab is not registered well in FastReport.Export.axd. How to register data for tabs in report? Thanks.


Code in html page :
<script type="text/javascript">
        $(document).ready(function () {
            $.ajax({
                type: "POST",
                url: "../api/webgl/FRCOALoad",
                success: function (data) {
                    $("#fastreport").html(data);
                },
                error: function (xhr, status, error) {
                    alert(error);
                }
            });
        });
    </script>
    <div id="fastreport"></div>

Code in ApiController :
<HttpPost>
    Public Function FRCOALoad() As String
        Dim retval As String = String.Empty

        Try
            Dim mySQLConnString As String = WebConfigurationManager.ConnectionStrings("myConnectionString").ConnectionString
            Using cnn As New OleDbConnection(mySQLConnString)
                cnn.Open()

                Using cmd As New OleDbCommand
                    cmd.Connection = cnn
                    cmd.CommandType = CommandType.Text

                    Dim selCompany As String = String.Empty
                    Dim selRE As Integer = 0
                    cmd.CommandText = "SELECT TOP 1 SetCompany, SetREBerjalan FROM tbSet"
                    Using dr As OleDbDataReader = cmd.ExecuteReader()
                        If dr.Read() Then
                            selCompany = dr.GetString(0)
                            selRE = dr.GetInt32(1)
                        Else
                            Throw New Exception("Record not found.")

    Finally solved.... in web application, we must use FastReport.Web.WebReport class instead of FastReport.Report.
    Using rpt1 As New FastReport.Web.WebReport
    Using rpt2 As New FastReport.Web.WebReport

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
