Warning: The DataTables table with the ID of [tablename] has encountered a login failure for the user with the username 'username'

Currently, I am utilizing the MVC framework /ASP.net and have incorporated datatables into my webpage. However, upon publishing the webpage to our server, I encounter an error where the datatable fails to function properly. Strangely enough, the datatable operates smoothly when running locally on my PC. It seems that all components including Stored procedure, BLL, DAL, DBML, and entities are functioning correctly as it worked perfectly before publishing to the server. I am at a loss as to which part of my code needs modification to resolve this issue. Is there something missing in my script that needs to be added for it to work? :(

<script type="text/javascript">
$(document).ready(function () {
    $('#tblPackages').DataTable({
        dom: 'lBfrtip',
        "scrollY": 380,
        "autoWidth": true,
        "scrollX": true,
        ajax: {
            url: '@Url.Action("GetNames", "AddPackages")',
            type: 'post',
            data: function (d) {                    
            },
            dataFilter: function (data) {
                var json = $.parseJSON(data);
                return JSON.stringify(json);
            }
        },
        columns: [
            { data: "Package" },
            { data: "CreatedBy" },
            { data: "DateCreated" },
            { data: "UpdatedBy" },
            { data: "DateUpdated" }
            ],
    });
});  

Answer №1

The JavaScript code provided appears to be working well in my experience. I've developed a sample MVC application and successfully implemented Jquery Datatables.

@section scripts{

<script type="text/javascript" charset="utf8" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.8.2.min.js"></script>
<script type="text/javascript" charset="utf8" src="http://cdn.datatables.net/1.10.9/js/jquery.dataTables.min.js"></script>
<script>
    $(document).ready(function () {
        $('#myTable').DataTable({
            "ajax": {
                "url": '@Url.Action("GetDataTableGridData","Home")',//ActionName,ControllerName
                "type": "GET"
            },
            "columns": [
                    { "data": "CreatedBy", "autoWidth": true },
                    { "data": "Package", "autoWidth": true },
                    { "data": "UpdatedBy", "autoWidth": true },
                    { "data": "DateUpdated", "autoWidth": true },
                    { "data": "DateCreated", "autoWidth": true }

            ],
        });
    });
</script>

}

I hope this information proves helpful to you.

After some investigation, I discovered the solution on my own. It appears that the error was not in the code of any of my scripts, but rather in the configuration of the app itself.

To resolve the Datatables Error when uploaded to the server, navigate to the Web.config file under configuration>configsections>connection strings

Update the connection string from

connectionString ="Data Source=sample1;Initial Catalog=[databasename]; Integrated Security =True";

to

connectionString ="Data Source=sample1;Initial Catalog=[databasename]; User ID=[input username here]; Password=[input password here]";

https://i.sstatic.net/ne4lQ.png

Additional Information:

  1. How do I determine which connection string needs to be modified? In my situation, I was utilizing the Link to SQL Class as my DBML. When I open my DBML file with the format [DataContextName].designer.cs

within the code is a declaration similar to this base(global::System.Configuration.ConfigurationManager.ConnectionStrings["dbWebApplicationsConnectionString1"].ConnectionString, mappingSource)

The highlighted text above needs to be updated in the Web.config file since this is the DBML/DataSource causing the connection errors.
