how to add hide event to the button in webform?

im trying to hide div by clicking the button, but it does hide it for a second and return the div (looks like it refreshing page).here is my html code :
<div id="page">
<p>First Paragraph</p>
<p>Second Paragraph</p>
<p>Yet one more Paragraph</p>
<asp:Button ID="Button1" runat="server" Text="Button" />
</div>
and here is my jquery code:
$(document).ready(function () {
$("#Button1").click(function () {
$("#page").hide();
});
});

What Rick said in his answer AND you need to add Type="Button" to your button.
<Button ID="Button1" type="button">Button</button>
The default button type is submit, which will cause the page refresh. AND, as Rick mentioned, ASP buttons will also submit. So, you need to use an HTML button and set the type="button" attribute.
From MDN
The type of the button. Possible values are:
submit: The button submits the form data to the server. This is the default if the attribute is not specified, or if the attribute
is dynamically changed to an empty or invalid value.
reset: The button resets all the controls to their initial values.
button: The button has no default behavior. It can have client-side scripts associated with the element's events, which are
triggered when the events occur.

An ASP Button with runat="server" causes a server post-back. If you aren't going to be acting on that click from the server, just use a client-side button like:
<button id="Button1" type="button">Button</button>

Set the client id mode to static on the button, then it'll work. It's not working because that hasn't been specified so the name is changing.
<asp:Button ID="Button1" ClientIDMode ="Static" runat="server" Text="Button" />
If you wanted to disable the postback to simply hide something without processing anything, then just using a client side button is the best option.

Server Controls, Client Controls, Panels, Default Buttons and Client Events

Ok so I would like to be able to be in the part number textbox press enter and it do a 'Quick Search'. However when press enter it activates the 'Search' Button instead. The 'Search' Button as the diagram shows is a default button of the panel it is in. But the 'Quick Search' is not in that same panel so I am kinda stumped on how to change this action so it calls click on the button on the 'Quick Search' and not the 'Search'. If this doesn't make since ask more questions and I will update the diagram and question.
Thanks in advance!
New Facts
In the browser Render ... these are in the same form
I want the Quick Search Button to be a client side button which makes it hard to use a panel and a default button

Try to place Part Number textbox and Quick Search button in separate Panel with DefaultButton="bnQuickSearck" attribute like follows:
<asp:Panel runat="server" DefaultButton="bnQuickSearck">
<asp:TextBox ID="tbPartNumber" runat="server"></asp:TextBox>
<asp:Button ID="bnQuickSearck" runat="server" Text="Quick Search" />
</asp:Panel>
EDIT If you have client-based button you can use the following code on javascript:
<div id="divId">
<input id="txtId" type="text" />
<input id="btnId" type="button" value="Quick Search" onclick="alert('test')"; />
</div>
<script>
$("#divId").bind("keypress", function (e) {
if (e.keyCode == 13) {
$("#btnId").click();
return false;
}
});
</script>
Make sure jQuery installed in your web application in this case.

It sounds like you have one big form. If this is the case, when you hit enter in the Part Number field it activates the default action, in this case it would seem to be the "Search" button. If you can break up your forms, they'll each have their own default actions. This will eliminate any need for crazy redirects, AJAX, server-side foo, etc.

Reset a page in ASP.NET without postback

I want to reset a form but I'm using a few "Required Field Validator" every time I click the reset button the error message shows requiring fields... What I tried:
ReuiqredFieldValidator.Enabled = false;
TextBox.Text="";
Response.Redirect("Samepage.aspx");
Response.Redirect("Request.RawUrl");
<input type=reset>

Try this:
<asp:Button
runat="server"
ID="reBt"
Text="Reset"
OnClientClick="this.form.reset();return false;"
CausesValidation="false"
/>
from here

You can apply ValidationGroup property to group of controls and the relevant asp button and do not provide ValidationGroup to reset button.
Or same can be achieved vice-versa
This is applicable as you using asp.net controls
Refer this link

you can try it
<input type="reset" causesvalidation="False">
It should work.
It works for input submit so I think it should work on input reset also.
Details Input =submit
Edit 1
Or if you are using jQuery you can use like this
$(':input','#myform')
.not(':button, :submit, :reset, :hidden')
.val('')
.removeAttr('checked')
.removeAttr('selected');

Stop Enter key from firing button click event

I am hoping this is easy, but I have looked and can't find a solution that will work for me. I have an aspx page with 2 user controls on it. One is a user control with a spun-up Auto Complete text box, that I want the "Enter" key to to cause a postback.
I have a button in the other control on the page that the onClick does something else. When I put text in the Auto Complete and press enter, the onClick for the button fires. Is there a way to have the enter key not cause the onClick to fire.
I have tried some javascript to disable the enter key press, but that breaks my text box enter.
What are my options.
EDIT 1
Here is some markup that I have
<uc:CompanyAC runat="server" ID="ac" />
<cc2:GenericGridView OnHtmlDataCellPrepared="HtmlDataCellPrepared"
KeyFieldName="CompanyID" ID="gridCompanies" DataSourceID="ManageCompaniesObjectDataSource" runat="server"
AutoGenerateColumns="False" />
The CompanyAC control has a textbox with some jquery that does autocomplete WS call (no need to show that
<asp:TextBox ID="searchbox" runat="server" Width="400px" />
The GenericGridView control contains a button
<asp:Button runat="server" ID="Button" Text="New" AllowFocus="false" OnClick="Button_Click" />
So what happens is that when the Enter Key is hit when the focus is on the Textbox, the button that is in the other control fires its onclick. I do not want that to happen, but I still want the postback to happen

try this
$('input').keypress(function(event){
if(event.keyCode==13)
{
event.preventDefault();
}
})

If you're using jQuery, you might try this:
$('input').on('keypress', function(e){
// Attempt form submit (after event function exits).
var f = $(this).parents('form');
setTimeout(function(){f.submit();}, 1);
// Return false to prevent form submit when enter key is pressed.
return !((window.event) ? window.event.keyCode : e.which)==13);
});

Multiple buttons on form, after clicking one how to select the other as the defualt ASP.NET

I have a ASP.NET form that has a search box, with a Go button. When you first visit the page and type in the search you can hit enter to click the go button. Then when presented with the list of results you click another button to mark the selected result for use. Then I allow the user to repeat to their hart's content to select multiple results. However the 2nd+ time that you enter a search query and hit enter it clicks the button instead of the button. You can see in the browser (IE7+) that the button is selected dispite you typing into the search field. How can I revert it so that after ever button press it selects the button as default?
I've tried using btnGo.Focus() in the button's onClick but that has no effect.

You can do a couple things.
Set the DefaultButton property of the form to the ID of your search button. This can work in a few situations, but lots of people have trouble with it, especially with complex or dynamic forms. Give it a try, simplest is best.
<form runat="server" DefaultButton="btnSearch"> ....
Add a javascript handler to the textbox in question, such that no matter the structure of the page, it will always click the search button when they press enter. The easiest way to do it would be with jQuery:
$("#myTextBox").keydown(function(e) {
if (e.keyCode == 13)
{
__doPostBack('" + <%= btnSearch.UniqueID + "','')");
}
});
but you could do something similar in the codebehind by adding an attribute to the textbox:
myTextBox.Attributes.Add("onKeyPress", "if (event.keyCode == 13) ... ")

<asp:Panel ID="pnl1" runat="server" DefaultButton="ImageButton1">
<asp:TextBox ID="TextBox1" runat="server">
</asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Submit" />
<asp:ImageButton ID="ImageButton1" runat="server" />
</asp:Panel>
or
http://weblogs.asp.net/jeff/archive/2005/07/26/420618.aspx

This should work:
<script language="javascript" type="text/javascript">
function FocusButton() {
var btn = document.getElementById('<%= btnGo.ClientID %>');
btn.Focus();
}
</script>
Then on your search textbox
<asp:TextBox ID="SearchTxt" runat="server" onClick="FocusButton">
