Description: While working on Asp.Net project I got the requirement to select all text in textbox on single click. I have used simple jquery’s select and focus method for this purpose.

Implementation: Let’s create a web page for demonstration purpose:

HTML source:
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
    <script type="text/javascript">
function selectAllText(sender)
        {
            $(sender).focus().select();
        }      
 </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>                
<asp:TextBox ID="TextBox1" runat="server" Width="250px" Text="Dummy text in Asp.Net Textbox" onclick="selectAllText(this)"></asp:TextBox><br />
        <asp:TextBox ID="TextBox2" runat="server" Text="This is dummy text in Asp.Net Multiline Textbox" TextMode="MultiLine" Rows="3" Columns="33" onclick="selectAllText(this)"></asp:TextBox><br /><br />
        <input type="text" style="width:250px;" value="Dummy text in HTML input control" onclick="selectAllText(this)" /><br />
        <textarea rows="3" cols="33" onclick="selectAllText(this)">This is dummy text in HTML textarea</textarea>  
    </div>
    </form>
</body>
</html>
