    I am trying to add my first parameterised report to an WebForms application.  I cannot figure out how to pass the parameter.  Having searched, a lot of posts are old, lead to blank pages, examples that use the old report viewer not the HTML 5 one and I cannot convert it etc.

    I have created a .trdp file and added it to the project.  It takes a parameter and the report works in preview, if I Hard code the parameter.

    My front end code to add the report viewer is:

    01.<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="ContractDisplay2.aspx.vb" Inherits="Intranet3.ContractDisplay2" %>
    03.<%@ Register Assembly="Telerik.ReportViewer.Html5.WebForms, Version=, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" Namespace="Telerik.ReportViewer.Html5.WebForms" TagPrefix="telerik" %>
    05.<!DOCTYPE html>
    08.<head runat="server">
    09.    <title></title>
    12.    <form id="form1" runat="server">
    13.        <div>
    14.            <p>report:</p>
    15.        <telerik:ReportViewer ID="ReportViewer1" runat="server"  style="border:1px solid #ccc;"
    16.            width="99%" height="99%"/>
    17.        </div>
    18.    </form>


    and in my code behind I have this:

    1.Dim reportSource As New Telerik.ReportViewer.Html5.WebForms.ReportSource()
    2.            reportSource.IdentifierType = Telerik.ReportViewer.Html5.WebForms.IdentifierType.UriReportSource
    3.            reportSource.Identifier = "ConsignmentProductReport.trdp"
    4.            reportSource.Parameters.Add("AccountNo", "ABC123")
    5.            ReportViewer1.ReportSource = reportSource


    The problem is that when I run it, the report is not rendered.

    Please can someone advise how to do this using WebForms / HTML5 viewer and .trdp files?

    As is often the case after posting for help, and a night's sleep, I have solved my problem :)

    So that no-one spends time on this, and in case it helps anyone else, the answer was:

    I had forgotten to provide a link to JQuery in my <head> tag:


    Also I changed the ReportViewer tag to this one:

                <ReportSource IdentifierType="UriReportSource" Identifier="ConsignmentProductReport.trdp">
                <%-- If set to true shows the Send Mail Message toolbar button --%>
                <SendEmail Enabled = "false" />


    And the report renders perfectly, complete with parameterised data.

    I had the same problem but I wasn't using .trdp files. I don't know if you found my post about it but It might help you in the future if you want to use the Visual Studio Reports with the HTML5 viewer.

    Hi John

    I didn't come across your post unfortunately, but thanks for sharing.  I looked at so many my head was spinning.  Love the functionality of Telerik tools but the learning curve sure does seem steep...

    Hello Stuart,

    Based on the posts so far, I assume that you've already managed to solve the problem by yourself. Good job!
    Also, I want to thank you for your feedback!  We are always trying to improve our documentation articles, so it will be really helpful if you point us to the articles that cause confusion and do not explain the subject in a clear and concise way. Our articles are being constantly changed due to adding new features, but we will also edit and refine them if it will contribute to a better documentation.

    As a side note, if the current subscription allows, you can open a support ticket. The ticket would guarantee you 24h response time (if it's not Lite support), while the forum posts are usually answered within 72h, but there is no guarantee that there would be an answer.

    Progress Telerik
