How to get current value
posted

I need to get the current value of the WebDropDown.

I wrote the following code.

I get exception in get_currentValue: "object does not support this property or method"

 

 
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind=" WebForm1.aspx.cs " Inherits="WebApplication43.WebForm1" %>


<%@ Register Assembly="Infragistics4.Web.v11.2, Version=11.2.20112.2159, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"
    Namespace="Infragistics.Web.UI.ListControls" TagPrefix="ig" %>

<html xmlns=" http://www.w3.org/1999/xhtml ">
<head runat="server">
    <title></title>
</head>
 
 <script language="javascript" type="text/javascript">
     function myFunction() {
         var combo = document.getElementById("WebDropDown1");  //$("#WebDropDown1");      
         var value = combo.get_currentValue();
     }
</script>

<body>
    <form id="form1" runat="server">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <div>
       <ig:WebDropDown ID="WebDropDown1" runat="server" Width="200px" CurrentValue="1">
        <Items>
            <ig:DropDownItem Selected="False" Text="1" Value="">
            </ig:DropDownItem>
        </Items>
    </ig:WebDropDown>
    <button onclick="myFunction()">Click me</button>
    </div>
 
    </form>
   
</body>
</html>

    Hello drpoalim,

    You should use “$find(“<your dropdown ID>”);” function to get reference to “WebDropDown” on Client-Side:

    var combo = $find(“WebDropDown1”);

    …

    Then you can use get_currentValue() function.
