Cascade

[Dave Nixon]

I am trying to do a cascading comboBox using an WebAPIAdaptor.  When I call dataBind() in JavaScript nothing seems to happen.

Hi Dave,   

  

Thanks for contacting Syncfusion Support.   

  

In ComboBox, component has to make a request to server, once the dropdown button clicked or type a text into combobox. The data will be bind after the action success.   

  

Please refer to the below code example:   

  

<code>   

  

function onCustomerChange(args) {   

        /// <summary>   

        /// Ons the customer change.   

        /// </summary>   

        /// <param name="args">The arguments.</param>   

        /// <returns></returns>   

        debugger   

        jobObj = document.getElementById('jobList').ej2_instances[0];   

        jobObj.dataSource = new ej.data.DataManager({ url: "/Api/JobNumbers/" + args.itemData.Id, adaptor: new ej.data.WebApiAdaptor(), crossDomain: true });   

        //jobObj.dataSource.url = "/Api/JobNumbers/" + args.itemData.Id;   

           

        jobObj.value = null;   

        jobObj.text = null;   

        jobObj.dataBind();   

        jobObj.enabled = true;   

   

   

   

    }   

  

</code>
