jQuery Code to Select All Text in TextBox on Click in Asp.Net

9/01/2014 - By Pranav Singh 0

This article will show you how you can select all or highlight the text present in a textbox or in a multiline textbox on focus or on click inside the textbox using jQuery in asp.net.


So for this article first we will create a new asp.net application and add the jQuery library reference in our asp.net page.

<script language="javascript" src="http://code.jquery.com/jquery-1.10.2.js"></script>

Now please check the below code for selecting all the text present in the textbox.

$("#<%=Control Id %>").click(function () { $(this).select(); });

So in above code we have raised event when mouse enter inside the textbox and user click on textbox. So here is the complete code.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SelectTextInTextBox.aspx.cs"
    Inherits="ProjectDemo_Asp.et.SelectTextInTextBox" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>jQuery Code to Select All Text in TextBox on Click in Asp.Net</title>
    <script language="javascript" src="http://code.jquery.com/jquery-1.10.2.js"></script>
    <script language="javascript">
        $(document).ready(function () {
            /*This is for TextBox*/
            $("#<%=TextBox1.ClientID %>").click(function () { $(this).select(); });

            /*This is for multiline textbox*/
            $("#<%=TextBox2.ClientID %>").click(function () { $(this).select(); });
        });
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        TextBox:
        <asp:TextBox ID="TextBox1" runat="server" Width="180px" Text="This is a demo text from asp.net"></asp:TextBox><br />
        TextArea:<asp:TextBox ID="TextBox2" runat="server" Height="106px" TextMode="MultiLine"
            Text="This is a demo text from asp.net"></asp:TextBox>
    </div>
    </form>
</body>
</html>

So just run the code and check the output.
