A guide on integrating Select2.js with WebForms

I am looking to make the switch from Ext.net to select2 js, but I'm struggling with integrating scripts and controls.

So far, I have started a new WebForms App, installed select2 through NuGet, and attempted to replicate a sample from the Project site.

Here is what my aspx code looks like:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="select2_test.Default" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Test Select 2</title>

    <script src="Scripts/jquery-1.7.2.js"></script>
    <script src="Scripts/select2.js"></script>
    <link href="Content/css/select2.css" rel="stylesheet" />
    <script type="text/javascript">
        $("#e12").select2({ tags: ["red", "green", "blue"] });
    </script>
    <script type="text/javascript">
        $(document).ready(function () { $("#e1").select2(); });
    </script>
</head>
<body>
    <form id="form1" runat="server" >
    <div>
        
        <!-- This one only works as a sample from the web, others do not work -->
        <select id="e1">
            <option  value="0">Test 0</option>
            <option  value="1">Test 1</option>
            <option  value="3">Test 3</option>
        </select>
    </div>
    </form>
</body>
</html>

What type of control should I use when applying JS on int data types? Are there any examples of using select2 js in WebForms?

Answer №1

If you're looking to implement a multiple select dropdown, you can use the following code snippet:

<select multiple id="e1">

    <option value="0">Test 0</option>

    <option value="1">Test 1</option>

    <option value="3">Test 3</option>

</select>

Answer №2

Caution should be exercised when incorporating Select2 into your project. It may lead to unintended consequences, such as altering the IDs of your controls. If you are working with knockout.js and choose to implement select2 on your dropdown lists, complications may arise that require less-than-ideal solutions. In general, it is advisable to exercise caution when introducing third-party components into your codebase, or maintain a vigilant oversight over their behavior.
