    I have a stand-alone HTML page based on the Report Viewer samples. This page calls the api/reports API. When my report is not parameterized, the Report Viewer works great and my report appears. I am now trying to add parameters to my report. 

    Here is my Report Viewer script that passes the parameter:
                    serviceUrl: "http://localhost:36563/api/reports/",
                    templateUrl: '/ReportViewer/templates/telerikReportViewerTemplate-',
                    reportSource: {
                        report: "MembersTest.trdx",
                        parameters: {
                            LastName: 'McGuy'

    Here is the parameter JSON being passed into '/api/reports/clients/085707-b6ce/parameters':
    [{"name":"LastName","type":"System.String","text":"Last Name","multivalue":false,"allowNull":false,"allowBlank":true,"isVisible":false,"autoRefresh":false,"hasChildParameters":false,"childParameters":null,"availableValues":null,"value":"McGuy","id":"LastName","label":"McGuy"}]

    So it appears to be passing the parameter. In fact, I added a text box that prints the LastName parameter, and when the report loads, it shows "McGuy", which is the value I am passing. But the report does not return any rows. Here is my report SQL:

    Last_Name, First_Name, Middle_Name, Birth_Date
    (Last_Name = @LastName)

    When I go through the "Configure SQL Data Source" dialogues in the stand alone Report Builder, it returns records based on my parameter, when I preview.

    I am not sure what I am doing wrong. Any help would be great.

    Hello Shawn,

    Make sure that the report parameter is connected properly to the SQL Data Source parameter placeholder. For more information, please refer to the Using Parameters with the SqlDataSource component help article.

    Yep, looks like that was it. Somehow the DataSource got disconnected from the report. Thanks!
