Asked On September 3, 2019 10:43 AM UTC

Hi all,
I have simple data source like this:

let ds = [
                        {
                            value: "value1",
                            text: "Value no 1"
                        },
                        {
                            value: "value2",
                            text: "Value no 2"
                        }
];

and I instantiate ej dropdownlist using that data source.
And then I want to select the item using the value (not the text).

This code does not work:
{
value: "value2"
}

But this code works:
{
value: "Value no 2"
}

Also getter, when I want to know what is the selected value, the .value is the same as the .text..
How I can achieve get/set using value not text?

Thank you.

Hi Oka, 
 
Greetings from Syncfusion support. 
 
Based on the code, we are not clear whether you are using EJ1 or EJ2. As you have mentioned “*EJ DropDownList*”, we have prepared a sample with EJ1 DropDownList for setting and getting value. You need to map the value field so that this will work fine. You can get the selected value by getSelectedValue() method. 
 
$(function () { 
    // declaration 
    ds = [ 
        { 
            value: "value1", 
            text: "Value no 1" 
        }, 
        { 
            value: "value2", 
            text: "Value no 2" 
        } 
    ]; 
    $('#bikeList').ejDropDownList({ 
        dataSource: ds, 
        fields: { text: "text", value: "value" }, 
        value: "value2" 
    }); 
}); 
function get() { 
    var ddlObj = $("#bikeList").data("ejDropDownList"); 
    alert(ddlObj.getSelectedValue()); 
} 
 
 
Please let us know if you have any concern on this.

As per your request, we have prepared same sample in ej2.
