Resolve an ASP page return postback issue

In the ASP. NET page in the text box, button and other server controls to enter the page will cause the postback, many online solution is to use JS to event.keycode==13 determine whether to press the ENTER, if it is Event.returnvalue = false; But this can only apply to IE, some browsers do not support Event.keycode, for example: Firefox is the use of Evt.which.

Here to give you a plan, after the use of the feeling is OK, if there are problems please forgive, give advice:

Page code:

<%@ Page language="C #"autoeventwireup="true"codefile="Default.aspx.cs"inherits="_default"%><! DOCTYPE HTML Public"-//W3C//DTD XHTML 1.0 transitional//en" "HTTP://WWW.W3.ORG/TR/XHTML1/DTD/XHTML1-TRANSITIONAL.DTD">"http://www.w3.org/1999/xhtml">"Server"> <title></title>"Form1"runat="Server"defaultbutton="Button1"> <div> <asp:textbox id="TextBox1"runat="Server"></asp:TextBox> <asp:button id="Button1"runat="Server"text="Button"Enabled="False"style="Display:none"/> <br/> <asp:textbox id="TextBox2"runat="Server"></asp:TextBox> <asp:button id="Button2"runat="Server"text="Button"/> </div> </form></body>
1, first to the page form set DefaultButton (here is set Button1).
Function: The button is clicked to submit the form for postback when the carriage returns.
2. Set enabled= "False" for Button1
Role: Enter after the discovery Button1 can not be used, so this submission will not be successful
3, if you do not want to see this Button1, add style style= "Display:none" to hide
Note: You cannot set the hide by the visible of the button, because this hides the carriage return or the postback
