DefaultButton in ASP.NET forms

Question

What is the best solution of defaultButton and "Enter key pressed" for ASP.NET 2.0-3.5 forms?

Answer 1

Just add the "defaultbutton" attribute to the form and set it to the ID of the button you want to be the default.

<form defaultbutton="button1" runat="server">
    <asp:textbox id="textbox1" runat="server"/>
    <asp:button id="button1" text="Button1" runat="server"/>
</form> 

NOTE: This only works in ASP.NET 2.0+

Answer 2

I don't want any button to be default, and it hits first one which is submit..

Answer 3

Maybe you need to clarify your question then, because it sounds like that's exactly what you're asking for...

Answer 4

Since form submission on hitting the enter key is a part of life with HTML, you'll have to trap the Enter key using javascript and only allow it to go through when it's valid (such as within textareas).
