Binded Grid Dropdown Option

Hi Team,

I have a batch edit grid with one of the columns having a dropdown edit type.  I have no problem with the dropdown options if they are already defined.

var Units = [{text: "CASE", value: "CASE"},{text: "BOX", value: "BOX"}, ]
{ field: "Unit", headerText: "Unit", width: 100, editType: ej.Grid.EditingType.Dropdown, dataSource: Units },


How do I bind dropdown options that are dynamic upon the value of  another column, ItemNo? I can't get the dropdown to bind with the results. I am using  ej.web.add.min.js Version 13.2.0.29.
My cell edit event is like below:

columns: [
          { field: "ItemNo", headerText: "Item No.", width: 150 },
          { field: "Unit", headerText: "Unit", width: 100, editType: ej.Grid.EditingType.Dropdown, dataSource: [] },
],
cellEdit: function (args) {
            var itemNo = args.rowData.ItemNo
            var vfield = args.columnObject.field;
            var vEditType = args.columnObject.editType;

            if (vEditType == "dropdownedit") {
                var grid = this._id;
                $.ajax({
                        url: "../Home/Data",
                        data: "&itemNo=" + itemNo,
                        type: 'GET',
                        success: function (results) {

                                 var dummyResults= [
                                        { text: "EACH", value: "EACH" },
                                        { text: "BAG", value: "BAG" },
                                        { text: "BOTTLE", value: "BOTTLE" },
                                   ];           

                                   /*Dropdown binding -- not working*/
                                 $("#" + grid + vfield).ejDropDownList({
                                         dataSource: dummyResults,
                                         fields: { key: "text", text: "value" }
                                  });

                                 /*I also tried binding dropdown option using this but also not working*/
                                // args.columnObject.dataSource = dummyResults;
                         }
              });

              
             }
}


Thanks.

Hi Lory, 
 
Thanks for contacting Syncfusion support, 
 
We have validate your provided code and we cannot access DropdownList properties when click cellEdit event because it created . So we have achieved your requirement by using the editTemplate property.In editTemplate write() we have bind the shipCountry dataSource to customerID  dropdown columnSo we suggest to use editTemplate .  
 
Please refer the below code snippet: 
 
  $("#Grid").ejGrid({ 
            dataSource: window.gridData, 
            allowPaging: true, 
             
            columns:[ 
          { 
            field: "CustomerID", headerText: 'Customer ID', validationRules: { required: true}, 
            editTemplate: {                              
                create: function () { 
                    return "<input>"; 
                }, 
                read: function (args) { 
                    return args.ejDropDownList("getValue");  
                }, 
                write: function (args) {//Get ShipCountry column dataSource and bind to the drop down customerID column 
                    var data = ej.DataManager(window.gridData).executeLocal(new ej.Query().select("ShipCountry")); 
                    args.element.ejDropDownList({dataSource: data });  
                    args.element.ejDropDownList("setSelectedText", args.rowdata.ShipCountry); 
                } 
            }, width: 90 
        }, 
                        { field: "EmployeeID", headerText: 'Employee ID', editType: ej.Grid.EditingType.Dropdown, width: 90 }, 
                        { field: "ShipCountry", headerText: 'Ship Country', width: 90, } 
          ] 
       }); 
 
Please refer the below attached sample  and documentation link: 



This is not meet your requirement , Please share the detail about your requirement.

Follow up question, how do I get the selected value and record of the dropdown? For other columns using args.value seems to work but when using the editTemplate the value that's return is undefined.

 columns: [
                        { field: "OrderID", isPrimaryKey: true, headerText: "Order ID", textAlign: ej.TextAlign.Right, validationRules: { required: true, number: true }, width: 90 },
                        {
                            field: "CustomerID", headerText: 'Customer ID', validationRules: { required: true},
                            editTemplate: {
                              
                               create: function () {
                                    return "<input>";
                                },
                                read: function (args) {
return args.ejDropDownList("getValue"); 
                                },
                                write: function (args) {
                                    var data = ej.DataManager(window.gridData).executeLocal(new ej.Query().select("ShipCountry"));
                                    args.element.ejDropDownList({dataSource: data }); 
                                    args.element.ejDropDownList("setSelectedText", args.rowdata.ShipCountry);
                                }
                            }, width: 90
                        },
                        { field: "EmployeeID", headerText: 'Employee ID', editType: ej.Grid.EditingType.Dropdown, width: 90 },  
                        { field: "ShipCountry", headerText: 'Ship Country', width: 90, }
                ],
              cellSave: function(args){
                if(args.columnName == "CustomerID"){
                         alert(args.value);
                }
