The default button on enter on an ASP.NET form

weblogs.asp.net/jeff/archive/2005/07/26/420618.aspx

Completely remove "Enter button behaviour":

<form ... onsubmit="return false">

In master page create style:

<

style type="text/css">

 

.hiddenbutton

{

 

}

display:none;

</

style>

 

Add button the first line after Form tag:

 

 

<

asp:Button ID="btnFakeDefault" CssClass="hiddenbutton" Enabled="false" runat="server" OnClientClick="return false;" />

 

 

In code behind for the event OnInit add explicit assignment for our button:

form1.DefaultButton = btnFakeDefault.UniqueID;

That is it! We disabled our default button without postback.

 

 

 

 

Assign your button as default (add this line of code into your page event Load):

Page.RegisterHiddenField("__EVENTTARGET", "btnSearch")

where "btnSearch" should be name of your button...
