I use javascript in asp.core. I have follow problem:

I have a list wich includes a ID and a Name. I display Name in dropdown list as follow:

$("#TypeList").ejDropDownList({

dataSource: dataManagerType,

fields: { value: "Name", text: "TypeId" },

enableFilterSearch: true,

enabled: true,

change: "GetSpecList",

validationRules: { required: true },

validationMessage: { required: 'is required.' },

});

What I want is to get selected value of dropdown list (Name).

I tried follow code:

alert(TypeList.value);

I get only the "ID" not the name. If I use TypeList.Text i get: "undefined"

Hi Marvin,

Greetings from Syncfusion support.

In DropDownList, text field will be displayed as DropDownList items and value field will be processed internally for selection. You can get the selected value from DropDownList through getSelectedValue() method using instance of DropDownList. Please refer to the following code

function getValue(args)

{

var ddl = $("#TypeList").data("ejDropDownList");

alert(ddl.getSelectedValue());

}

</script>

You can also get the selected value and text through arguments of change event during selection. Refer the following code

$("#TypeList").ejDropDownList({

dataSource: dataManagerType,

fields: { value: "Name", text: "TypeId" },

enableFilterSearch: true,

enabled: true,

change: "GetSpecList",

validationRules: { required: true },

validationMessage: { required: 'is required.' },

});

function GetSpecList(args) {

console.log(args.selectedText); // get text

console.log(args.selectedValue); //get value

}

We have prepared a sample with your code for reference. Please refer to the below given link
