I want to give user option to either select a value from ddl or to enter one in the textbox. However, since both are sources for binded table field, both shouldn't be active simultaneous so I use a jquery to disable the texbox if a value is selected in ddl or to re-enable if none. But when I try to do the same for the ddl, re-enable it lose the source for the ddl. How it should be done?
 
  1. <div class="row no-gutters" onchange="funcLocation()">  
  2.     <div class="col-md-2">  
  3.          <label class="form-control text-white" style="background-color:mediumorchid;">Location </label>  
  4.     </div>  
  5.     @if (Model.RALocation == true)  
  6.     {  
  7.         <div class="col-md-3">  
  8.            <select id="LocS" class="form-control border-danger" asp-items="@Model.SelectLocation" asp-for="RiskAssessmentMain.Location">  
  9.            <option value="">--Select Location--</option>
