<asp:TextBox ID="User_IDTextbox" Rows="3" Columns="50" TextMode="MultiLine" onkeypress="checkEnter(event)" runat="server"></asp:TextBox>

and ur JS function will be

function checkEnter(event)
     if (!event) event = window.event;
     key = event.keyCode ? event.keyCode : event.which;    

     if (key == 13)  //13 is keycode for enter key
       //do stuff here.

window.event contains which key is pressed. In IE event.keyCode contains the value (While pressing enter the value will be 13). But in browsers such as firefox event.which will contain the value. This code to work with all browsers.

That javascript listens for the enter key which is only part of the solution. Inside the javascript that easwaranp provided, put code that adds "\r\n" to the textbox. This will give the newline in place of the enter.

If you just wanted the newline to write in the textbox from the codebehind you could use Environment.NewLine
txtTest.Text = "First Line " & Environment.NewLine & "Second Line"

txtTest.Text = "First Line " + Environment.NewLine + "Second Line";
