Fire event on enter key press for a textbox

Question

I have the following asp.net textbox control.

<asp:TextBox ID="txtAdd" runat="server" /> 

After the user writes something in this textbox and presses the ENTER key, I want to run some code from codebehind.

What should I do?

Using jQuery I captured ENTER key and fired some hidden button event

$(document).ready(function(){     $(window).keydown(function(e){       if(e.keyCode == 13) $('#<% addbtn.ClientID %>'.click();    });  }); 

Is there any better way ?

Answer 1

1. Wrap the textbox inside asp:Panel tags

2. Hide a Button that has a click event that does what you want done and give the <asp:panel> a DefaultButton Attribute with the ID of the Hidden Button.

<asp:Panel runat="server" DefaultButton="Button1">    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>        <asp:Button ID="Button1" runat="server" style="display:none" OnClick="Button1_Click" /> </asp:Panel> 

Answer 2

ASPX:

<asp:TextBox ID="TextBox1" clientidmode="Static" runat="server" onkeypress="return EnterEvent(event)"></asp:TextBox>     <asp:Button ID="Button1" runat="server" style="display:none" Text="Button" /> 

JS:

function EnterEvent(e) {         if (e.keyCode == 13) {             __doPostBack('<%=Button1.UniqueID%>', "");         }     } 

CS:

protected void Button1_Click1(object sender, EventArgs e)     {      }
