in the textbox and when the user clickon the text box it should clear the field.

Here's what I have.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this.  onkeydown will not work here.
<asp:TextBox on ID="TxtKeywords" runat="server" Text="Enter Keywords" onclick="this.value='';" />
Apologies, meant this!
<asp:TextBox ID="TxtKeywords" runat="server" Text="Enter Keywords" onclick="this.value='';"></asp:TextBox>
