AutoComplete datasource request is not sending "text"

[Michael]

I'm trying to implement the example I'm seeing here: https://demos.telerik.com/aspnet-core/autocomplete/serverfiltering.  My code is identical to what is provided in the example.

When using the demo on this page, I see the URLs like this (I'm pulling these from developer tools in the browser):

https://demos.telerik.com/aspnet-core/Home/GetProducts?text=test&filter%5Bfilters%5D%5B0%5D%5Bvalue%5D=test&filter%5Bfilters%5D%5B0%5D%5Boperator%5D=contains&filter%5Bfilters%5D%5B0%5D%5Bfield%5D=ProductName&filter%5Bfilters%5D%5B0%5D%5BignoreCase%5D=true&filter%5Blogic%5D=and

The key I want to point out here is that "text=test" is passed on the querystring to my backend page.

However, when I do this in my development environment, no "text" key is passed, I do however have all the filter keys being passed.

Am I doing something wrong?  My code is literally the same as in the example.

Thanks!

Hi Michael,

The text argument is passed because the Data method is used for the read operation that calls the onAdditinalData function that returns the text argument for the server end-point: 

@(Html.Kendo().AutoComplete()
          .Name("products")
          .DataTextField("ProductName")
          .Filter("contains")
          .MinLength(3)
          .HtmlAttributes(new { style = "width:100%" })
          .DataSource(source => {
              source
                  .Read(read =>
                  {
                      read.Action("GetProducts", "Home")
                      .Data("onAdditionalData");
                  })
                  .ServerFiltering(true);
          })
    )
    <div class="demo-hint">Hint: type "che"</div>
    <script>
    function onAdditionalData() {
        return {
            text: $("#products").val()
        };
    }
    </script>

If you are missing the Data method configured in read operation and/or the JS function that returns the argument, it is expected in the request the text field to not be present. 

If it seems that you have all those pieces, please either share some code of the case, or provide a simple project so that I can see what is going on.

Thanks for the help, that was my problem.  I had to ensure the Id's matched between the control and the javascript, once I did that, all was well.
