Hello Rich,

You can use:

var ddl = $("#clientid").data("kendoDropDownList");
ddl.dataSource.data([]); // clears dataSource
ddl.text(""); // clears visible text
ddl.value(""); // clears invisible value

I use that exact code:
var ddl = $("#ddlSubAction").data("kendoDropDownList");
ddl.dataSource.data({});

But instantly recive an error that states that the object does not support the property or method 'slice'

Hello Chuck,

You are probably using a newer Kendo UI version. In this case, please provide an empty array argument instead of an empty object.

var dropdownlist = $("#Merchant").data("kendoDropDownList");
                dropdownlist.enable(false); // Disable the dropdownlist
         
            $("#Merchant").data("kendoDropDownList").value(null); // Clear the value
