jQuery to expand or resize Asp.net multiline textbox on mouse over and mouse out

Introduction: In this article I am going to share the code trick to increase Asp.Net normal textbox or multiline textbox size (height, width) on mouse hover and decrease or reset textbox size on mouse out using jquery .

jQuery to expand or resize Asp.net multiline textbox on mouse over and mouse out

Description: While working on feedback form in asp.net project I got the requirement to display a textbox for getting user comments. There were some other textboxes along with this comments textbox. Since user can submit lengthy comments, it is recommended to use multiline textbox. But I don’t want to place large multiline textbox on the form because it was looking weird (not in symmetry with other normal textboxes).

So I decided to place the multiline textbox with the dimension same as other textboxes and using jquery implemented the functionality so that when user take the mouse over this textbox to enter comments it expands itself and on mouse out it resets to its original dimension as shown in demo image above.

Implementation: Let’s create a sample web page to demonstrate the concept.

HTML Source

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $("#<%= txtComments.ClientID %>").hover(function () {
                $(this).animate({ width: 300, height: 100 }, 400);
            function () {
                $(this).animate({ width: 200, height: 20 }, 400);

    <form id="form1" runat="server">
                    <td>Comments : </td>
                    <td><asp:TextBox ID="txtComments" runat="server" TextMode="MultiLine" Style="width:200px; height:20px;"></asp:TextBox></td>
