asp panel default button property is not working in ie for live application

I have a page having multiple buttons and search functionality.I have placed one button and textbox in a panel.After writing seach text if I hit Enter,it works well for all the browsers on local, but for live application this is not working in IE.
The html is:
<asp:Panel ID="pnlSearch" runat="server" CssClass="search" DefaultButton="btnSearch">
<h2>
Explore QualityStocks without logging in</h2>
<asp:TextBox ID="txtSearch" CssClass="txt" runat="server" ToolTip="Stock Ticker" ></asp:TextBox>
<asp:Button TabIndex="0" ID="btnSearch" runat="server" ClientIDMode="Static" CssClass="btn" OnClick="btnSearch_Click" />
</asp:Panel>
What am I missing to do?
Thanks in advance,

Set panel default button gives error, must be ibuttoncontrol

I am trying to set default button for asp panel. Instead of asp button I am using button control with type="submit". I am getting error: "The DefaultButton of 'pnlSSN' must be the ID of a control of type IButtonControl.”.
This is the code I have:
<div class="input-append" id="divSSN"> <asp:Panel ID="pnlSSN"
runat="server" DefaultButton="btnSSN">
<asp:TextBox ID="txtSSN" runat="server" CssClass="span8" Width="200px"
placeholder="Enter valid Social Security Number">
ValidationGroup="validationSSN" />
<button runat="server" id="btnSSN"
onserverclick="btnSSN_Click" causesvalidation="true"
ValidationGroup="validationSSN" class="btn"
type="submit">Search</button> </asp:Panel> </div>
I also tried setting both pnlSSN.DefaultButton = btnSSN.ClientID; and pnlSSN.DefaultButton = btnSSN.ID; but I am getting the same error.

DefaultButton must be ASP.Net button server control instead of html Button
<asp:Panel runat="server" ID="pnlSSN" DefaultButton="btnSSN">
...
<asp:Button runat="server" ID="btnSSN" OnClick="btnSSN_Click" />
</asp:Panel>
Besides, your asp:TextBox tag is not well-formatted. Remove > at the end of Number">

Submit by pressing enter asp.net

I am wondering why this, submitting on pressing enter, is only working on ie and not on google chrome...
This is the code I use actually :
<div class="TxtBox">
<asp:Panel ID="lepanel" runat="server" DefaultButton="Connect">
<asp:TextBox ID="TxtUserLogin" runat="server" TabIndex="1" Text="login" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="*"
Display="Static" ControlToValidate="TxtUserLogin"></asp:RequiredFieldValidator>
<asp:TextBox ID="UserPass" runat="server" TabIndex="2" Text="password" TextMode="Password" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="*"
Display="Static" ControlToValidate="UserPass"></asp:RequiredFieldValidator>
<asp:LinkButton ID="Connect" runat="server" OnClick="Connect_Click" TabIndex="3">connect</asp:LinkButton>
</asp:Panel>
<asp:Label ID="MsgError" runat="server" />
<div class="ForgottenPass">
forgotten password ?
</div>
<div class="RememberMe">
<asp:CheckBox runat="server" ID="chkBoxRemember" />
stay signed in
</div>
</div>

A LinkButton renders as a HTML anchor tag.
HTML anchor tags do not submit HTML forms. Therefore when you click Enter, this is not actioning any submit button.
A Button renders as HTML <input type="submit" />
An ImageButton renders as HTML <input type="image" />
These elements will both action your form.
Therefore changing LinkButton to Button or ImageButton is the best solution.
Using a LinkButton is also bad for users who do not have javascript enabled.

This is a known issue, when you add as default a link button (actually a link) and not a real button then there is a case that is not trigger properly.
So if you change it to real button you make it work.

Asp.Net popup error message

Is there a way I can display an error message in a popup box? I'm using Asp.Net (C#), and on our webpage, if an order goes throug incorrectly we display an error message. Now, we would like to be able to do so using some sort of pop-up method (maybe Ajax?) - it should be able to take a string value to display the error message.

For a simple approach, you can have a script block that contains alert("your error message"). If you want the popup to be styled as the rest of your website then you could render your error message into a div element and use a jQuery dialog to display it as a modal dialog within your page.

I have used Ajax to accomplish this myself.
Using the ModalPopupExtender and setting the PopupControlID to an Asp Panel, I usually put this into a User Control so it can be easily used through a website.
However below is a snippet of the asp.net code
<div class="modalPopupAlign">
<asp:LinkButton ID="lnkConfirm" Style="display: none;" CausesValidation="false" runat="server" PostBackUrl="#">Confirm</asp:LinkButton>
<ajax:ModalPopupExtender ID="lnkConfirm_ModalPopupExtender" runat="server" TargetControlID="lnkConfirm" PopupControlID="pnlConfirmation" BackgroundCssClass="modalBackground" DropShadow="true" RepositionMode="None">
</ajax:ModalPopupExtender>
<div id="pnlConfirmation" class="modalPopup" style="display: none;">
<br />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<div class="modalPopupContainerAlign">
<div>
<asp:Image ID="imgIcon" CssClass="modalPopupImage" runat="server" />
<asp:Label ID="lblMessage" CssClass="modalPopupMessage" runat="server"></asp:Label>
<div class="modalPopupTextbox"><asp:TextBox ID="txtValue" Width="200px" MaxLength="100" Visible="false" runat="server"></asp:TextBox></div>
<asp:Button ID="btnAction" runat="server" CausesValidation="false" CssClass="defaultButton" Text="OK" />
</div>
</div>
</ContentTemplate>
</asp:UpdatePanel>
</div>
</div>
It does take some time to get it working properly as I have had a few errors with the script manager, which I currently have setup in a master page.
Just might give you a direction to head for, and the CSS can help shape and colour the message box.
Although this is a complex way in some respect but has many uses.

You can do this with simple javascript like this...
alert("my error message");

i want to show or hide some controls in repeater through javascript in c# 3.5

I have a repeater control in which i have loaded questions. I want to display a textbox and a button when some one click the question and answer that question with out posting back the page. the textbox and button get hide when the user post the answer

U could do this with ajax using an UpdatePanel.
The javascript will be generated for you by the ASP.NET engine.
You can learn more on the UpdatePanel here.

<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<span onclick="ShowTextBox(<%# Container.ItemIndex %>)"><%# Eval("Question") %> </span>
<div style="display:none" id='<%# "dv_"+Container.ItemIndex %>'>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<asp:Button ID="Button2" runat="server" Text="Button" />
</div>
</ItemTemplate>
</asp:Repeater>
AND Add some script
`<script type="text/javascript">
function ShowTextBox(index) {
$("#dv_" + index).show();
}
</script>`
Remember you should include the jquery file in the head.
