remove remember me check box from asp:login control - asp.net

I want to create a login with ASP.NET 4 but without rememberMe check box. Is any way to do this?

Take a look at this
If you are using that control, you just need to put something like below in your aspx file:
<asp:Login DisplayRememberMe="False" />

Press the drop down menu and press Convert To Template. And then just delete it.
In addition, there is a property which is DisplayRememberMe you can just put it false.

You can do this just by using property of login control to control the display of RememberMe
for that you have to set that property equals to false
<asp:Login ID="Login1" runat="server" DisplayRememberMe="false">
</asp:Login>
or you can also convert this into template and can remove whatever items you don't want to use. by default template control look like this . you can remove remember me from this HTML .
<asp:Login ID="Login1" runat="server" DisplayRememberMe="false">
<LayoutTemplate>

How can I make the ASP.Net Login control render correctly in Internet Explorer 7?

I'm using an ASP.Net Login control in my application. In Chrome, Firefox, and IE 9, everything works ok. But we still have users on IE 7, and everything is NOT OK for them; the Login control's "UserName" box doesn't display, so they just have to guess at where to start typing in their username (see screen cap).
I've already tried converting the control to a Template and playing with the padding, etc. The control renders as a nested table, like so:
<asp:Login ID="UserLogin" runat="server" OnLoggedIn="UserLogin_LoggedIn"
DisplayRememberMe="false" UserNameLabelText="Username">
<TextBoxStyle CssClass="round" />
<TitleTextStyle Font-Bold="True" Font-Size="Large" />
<LabelStyle Font-Bold="True" />
<LayoutTemplate>
<table cellpadding="1" cellspacing="0" style="border-collapse:collapse;">
<tr>
<td>
<table cellpadding="5">
<tr>
<td align="center" colspan="2" style="font-size:Large;font-
weight:bold;">Log In</td>
</tr>
<tr>
<td align="right" style="font-weight:bold;">
<asp:Label ID="UserNameLabel" runat="server"
AssociatedControlID="UserName">Username:</asp:Label>
</td>
<td>
<asp:TextBox ID="UserName" runat="server" CssClass="round" Width="100">
</asp:TextBox>
<asp:RequiredFieldValidator ID="UserNameRequired" runat="server"
ControlToValidate="UserName" ErrorMessage="User Name is required."
ToolTip="User Name is required." ValidationGroup="UserLogin">*
</asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td align="right" style="font-weight:bold;">
<asp:Label ID="PasswordLabel" runat="server"
AssociatedControlID="Password">Password:</asp:Label>
</td>
<td>
<asp:TextBox ID="Password" runat="server" CssClass="round"
TextMode="Password" Width="100"></asp:TextBox>
<asp:RequiredFieldValidator ID="PasswordRequired" runat="server"
ControlToValidate="Password" ErrorMessage="Password is required."
ToolTip="Password is required." ValidationGroup="UserLogin">*
</asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td align="center" colspan="2" style="color:Red;font-weight:bold;">
<asp:Literal ID="FailureText" runat="server" EnableViewState="False">
</asp:Literal>
</td>
</tr>
<tr>
<td align="right" colspan="2">
<asp:Button ID="LoginButton" runat="server" CommandName="Login"
Text="Log In" ValidationGroup="UserLogin" />
</td>
</tr>
</table>
</td>
</tr>
</table>
</LayoutTemplate>
<FailureTextStyle Font-Bold="True" />
</asp:Login>
Does anyone have any ideas?
UPDATE: Adding ie7-js to the mix made no difference at all. So I removed it and then tried removing the CssClass="round" from the Username and Password text boxes; that was the culprit. I don't know what in jquery.corner is causing the problem, but all it means is my login page will have square corners and the rest of the application will have rounded corners - I can live with that.
I'm going out on a limb here and saying that this is a CSS issue.
You're referencing a CssClass called round - Ideally we would need to see that first.
Though I am going to guess you have a .round:focus {} too? to style the currently focused textbox. If so, this isn't supported in less than I.E 8 and will likely have some funky behaviour...
If this is the case, then check out ie7-js to help you gain missing support.

asp.net (Visual Studio 2010) form validation controls

Afternoon All,
I have a web form that i wish my user to fill out. On the form i have three fields that i wish to set validation on. One of these is a normal textbox, the other a textbox associated with a calendar icon and my last field is a drop down list that has data held in it populated from an Enum list.
Im not too worried about my dropdown list yet, but i am getting slightly frustrated with my other two textboxes. I have used a 'Required Filed Validator' on both of these and only want the validation to kick in when the users clicks the submit button. At the moment if you tab or click between these two fields the validation kicks in.
Here is my web form....
<table id="table-3">

If anyone cant point me in the right direction that would be great. Many thanks in advance.
Betty
You can set the EnableClientScript property of the RequiredFieldValidator to false:
<asp:RequiredFieldValidator ID="RequiredFieldVal1"
ControlToValidate="txtAgendaDate"
ErrorMessage="Date"
Text="*"
EnableClientScript="false"
runat="server"/>
that way the validation will accur only after the user posts the form.
Hope this helps,
Shai.

You are probably failing one of the validators requirements and just not displaying the error message. I would look at your validators and make sure that they are not suppressing error messages or you're passing those messages to a summary control

Here's the Design View:
I'd like to add code in the code behind to perform additional edits. I added the "ErrorMessage" LiteralControl. How do I access it from the code behind or is there a preffered way to display a custom message using the control's functionality?
Suggest using the CreateUserWizard property CreateUserButtonStyle-CssClass.
Define yourself a new class:
<style type="text/css">
.foo{
margin-left: 120px;
}
</style>
Then set the wizard button property:
<asp:CreateUserWizard CreateUserButtonStyle-CssClass="foo"
The only problem is that the markup emitted has the alignment as "right" instead of what we want: "left".
See this image for a look in Firebug if the table cell alignment was set to LEFT.
Solve the right/left <td> contents alignment problem, and you're set!
Use jQuery to find this button, get its parent <td>, and set its align attribute to left.
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>
<style type="text/css">
.foo
{
margin-left: 120px;
}
</style>
<script type="text/javascript">
$(document).ready(function () {
var btn = $("#CreateUserWizard1___CustomNav0_StepNextButtonButton");
btn.parent().attr('align', 'left');
});
</script>

Maybe it will help (us), if you post a example code, e.g. where you are setting EnableViewStateMac.
But for now, it looks like, your field is not correctly initiated, so instead of true/false it has the value "null". But it´s just a guess, recommending more is quiet impossible for now. ;)
I've gotten invalid viewstate errors before, and in researching, I think for me the issue was happening is in one of my really large pages. I read somewhere that really large pages can have that issue happen, for a reason I now forget...
