Use a ASP.NET WaterMark TextBox

It is in Ajax Toolkit

You, can give in Code behind like follows

textBox.Attributes.Add(“onfocus”, “clearText(this,’” + defaultText + “‘)”);

And also refer to this to know more.

You can using "placeholder" properties for textbox.

Example

<asp:TextBox ID="TextBox1" runat="server" Width="233px" placeholder="Search"></asp:TextBox>

You could use the HTML5 placeholder attribute for that. The downside is that it's only supported by some browsers. Fortunately you have JQuery Placeholder to the rescue. This plugin makes the placeholder behavior available for unsupported browsers.
