Many new developers encounter a situation where there is a need to add dynamic control on the client side. This article will help them to understand how to add dynamic control on the client side using jQuery. Here I have described it using a step-by-step approach.

Initial chamber

Step 1

Open Visual Studio and create an empty website, provide a suitable name such as AddDynamicTextBox.

Step 2

In Solution Explorer you will get your empty website. Then add web forms.

For Web Form

AddDynamicTextBox (your empty website). Right-click and select Add New Item, then Web Form. Name it AddDynamicTextBox.aspx.

Design chamber

Step 3

Open AddDynamicTextBox.aspx file and write some code for the design of the application.

First add the jQuery plugin to your head section. Here I have used jquery-1.10.2.js plugin for demonstration purposes.

How to add in your page

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

Write some script for add or remove as in the following:

<script type="text/javascript">
$(document).ready(function () {
$('#add').click(function () {
var table = $(this).closest('table');
console.log(table.find('input:text').length);
if (table.find('input:text').length < 50) {
var x = $(this).closest('tr').nextAll('tr');
$.each(x, function (i, val) {
val.remove();
});
table.append('<tr><td style="width:200px;" align="right">First Name <td> <input type="text" id="current Name" value="" /> </td><td style="width:200px;" align="right">Last Name <td> <input type="text" id="current Name" value="" /> </td></tr>');
$.each(x, function (i, val) {
table.append(val);
});
}
});
$('#del').click(function () {
var table = $(this).closest('table');
if (table.find('input:text').length > 1) {
table.find('input:text').last().closest('tr').remove();
}
});
});
</script>

Add HTML on your page and your page will look like the following:

<div>
<table border="0" cellspacing="2">
<tr>
<td style="width: 200px;" align="right">Name
<td>
<input type="text" id="Job Name" value="" />
</td>
</td>
</tr>
<tr>
<td align="right">Versions</td>
<td>
<select id="version" style="width: 350px;">
<option value="">SELECT</option>
</select>
</td>
</tr>
<tr>
<td align="right">Test Scripts</td>
<td>
<select id="testscripts" style="width: 350px;"></select>
</td>
</tr>
<tr>
<td align="right">datas</td>
<td>
<input type="button" id="add" value="Add" />
<input type="button" id="del" value="Del" />
</td>
</tr>
<tr>
<td style="height: 3px" colspan="2"></td>
</tr>
</table>
</div>

Now your code looks as in the following:

Now your page looks as in the following.

AddDynamicTextBox.aspx

var x = $(this).closest('tr').nextAll('tr');
$.each(x, function (i, val) {
val.remove();
});
table.append('<tr><td style="width:200px;" align="right">First Name <td> <input type="text" id="current Name" value="" /> </td><td style="width:200px;" align="right">Last Name <td> <input type="text" id="current Name" value="" /> </td></tr>');
