How would I let 1 .aspx page use another .aspx page's code?

I have 2 aspx files in my project. The first.aspx page has some content on it and when I click on a button, it will launch a frame (second.aspx that only has code to show a calendar) on the same page.
Now once that calendar(second.aspx) loads on first.aspx, I want to click a link on the calendar that will .show() a hidden DIV on the first.aspx page.
How do I access code cross pages? In other words, how can I write some code in second.aspx that will affect first.aspx.

What you're asking for is not really possible. You're probably approaching it the wrong way. What you should do is turn your calendar page into a user control so that it can be used seamlessly in first.aspx.
Here is how to get started with user controls in asp.net:
After you turn it into a user control there are different approaches to getting access to the properties of the user control from your page. Here is one approach using the FindControl method.
Hope that helps.

The easiest solution would be to show and hide your div with jquery. Simple give your div a class like:
<div class="myCalendarDiv" style="display:none" />
And your Button should look like this:
<asp:Button id="myButton" OnClientClick="return ShowCalendar();" runat="server" />
<script type="text/javascript">
function ShowCalendar() {
$(".myCalendarDiv").show();
return false;
}
</script>
Another way would be instead of creating a seprate webpage for the calendar, as proposed you can use a jquery dialog, or make a usercontrol and embedd it on the same page.

(Posted on behalf of the OP).
So since I was dealing with an Iframe, I found out that you can target the parent window which would be first.aspx.
I used "window.parent.MYFUNCTION();" to call my JavaScript function on first.aspx and show the div.

Adding style to a modal popup

I have added a modal popup AJAX control to my website.
When a button is clicked it correctly appears but im running into trouble with the styling.
At the moment I have added a new style to my site master Site.css style sheet but it is not taking effect on the popup.
I have a separate style sheet called 'modalBackGround.css'
This is the css class:
body
{
background-color:#000000;
}
This is my modelpop AJAX control, note the ccs property:
<cc1:ModalPopupExtender ID="Button2_ModalPopupExtender" runat="server"
TargetControlID="Button2"
BackgroundCssClass="modalBackGround"
DropShadow="true"
OkControlID="btnOk"
CancelControlID="btnClose"
PopupControlID="Panel1" >
</cc1:ModalPopupExtender>
How do I correctly apply this style sheet to the background of the popup to solve the transparency issue?

Sorted this. Please note. To anyone who is basing their pages on a site master. You can declare multiple css style sheets through the use of the 'link' property within the 'head'. This will then allow you to use these styles on every page as it is declared on the master.

How to change the color of the HyperLink in ASP.NET

i am doing mini ERP project., in that i have 3 frames.
frame is used as Header where i have "Home" and "logout" image button
when i click "Home" the frame3 goes to Home page and when i click "Logout" button, all the frames disappears and main window of "Login" screen comes.
i have used "Home " and "Logout" button in image using Hyperlink control in ASP.NET
the problem is due to Hyperlink the button gets blue border around it.
i want to remove that border around the image button.
can any one knows how to remove that border
here my codes
<asp:HyperLink ID="HomeButtonlink"
BorderWidth="0px"
Font-Overline = "False"
ImageUrl="~/Images/Untitled-5.png"
runat="server"
Height="100%"
Target ="frame3"
NavigateUrl="~/About.aspx"
BorderStyle="None"></asp:HyperLink>
thanks in advances

I would create a new css class for this instead:
<asp:HyperLink ID="HomeButtonlink" CssClass="linkbutton"
ImageUrl="~/Images/Untitled-5.png"
runat="server" Target="frame3" NavigateUrl="~/About.aspx"></asp:HyperLink>
and you can define your class like this:
a.linkbutton, a.linkbutton:visited, a.linkbutton img
{
border: none;
outline: none;
}
You gain very little by using the asp.net server control. You can do the same like this:
<a href="<%=ResolveUrl("~/about.aspx")%>" target="frame3" class="linkbutton">
<img src="<%=ResolveUrl("~/images/untitled-5.png") %>" />
</a>

The border around images that are links is part of the default HTML stylesheet.
To get rid of it for all images, add a simple bit of CSS to your page as follows:
img {border:none;}
This is a common thing to want to do, as very few people actually want the default behaviour these days. You may want to look into adding a 'reset' stylesheet to your site to get rid of all the unwanted default behaviours. It will also make your page work more consistently between different browers.
Here's a link to a related question to help you find out more: https://stackoverflow.com/questions/116754/best-css-reset
If for some reason you don't want to affect all the image links on your site, you could also do a more specific stylesheet for it since you've given it an ID:
#HomeButtonlink {border:none;}
You could also add a CSS class to the object, and then reference that in your stylesheet if you wanted to apply it to a group of buttons.
...but frankly, I'd just go with the full reset if I were you.

Ajax Content Loading(Processing) image or indicator

in part of my web page, I have couple of asp:image Thumbnails, onclick I use ajax modal popup extender to show the imgae in full size which are working fine, what I need to add is to have a processing image or indicator both in thumbnail and modal popup extender,
I also have ajax autocomplete that is working fine, I need to add some indicator or processing image to it as soon as user start typing a word.
any idea?
Thanks in advance

You can use an update progress control to display a progress template within your update panel. It displays the contents of the ProgressTemplate tag whenever a postback occurs:
<asp:UpdateProgress runat="server" id="UpdateProgress" AssociatedUpdatePanelID="SomePanel" >
<ProgressTemplate>
<img src="processing.gif" alt="Processing" />
</ProgressTemplate>
</asp:UpdateProgress>
Also, I've found Preloaders useful as a source of animated GIFs for this purpose.

Look at http://www.ajaxload.info/. There are a ton of images there. Once the user types in some letters, however many you need, then display the ajax loader gif next to the textbox.

Assuming that you want the loader/indicator within control, so, one way could be to subclass the PopupExtender control, add asp:UpdateProgress, and put a loader.img in there.

asp: LoginStatus control as a button, not text

I'm pretty new to this, infact this is my first post.
I'm using Visual Studio 2005. On my .aspx page, I have a 'loginStatus' control so the user can logout of a page which works well. However the 'loginStatus' control is not a button, it's text ("logout"). Is it possible to make this into a button?
Here is the line of code:
<asp:LoginStatus ID="LoginStatus1" runat="server" OnLoggingOut="LoginStatus1_LoggingOut" />
Would I just add some style somehow? If so, please help me.
Thanks.

Haven't tested this, but it might solve your problem : forum post
Otherwise you might use jQuery to solve this. (I think...)

You can try this:
<asp:LoginStatus ID="HeadLoginStatus" runat="server"
LogoutAction="Redirect"
LogoutText="<input type='button' value='Log Out' />"
LogoutPageUrl="~/"/>
The LogoutText attribute contains the definition of a simple button, that you can customize with css and js.

Just use LoginImageUrl or LogoutImageUrl
<asp:LoginStatus runat="server"
LogoutImageUrl="~/App_Themes/Theme1/Images/logout.png"
LoginImageUrl="~/App_Themes/Theme1/Images/login.png" />

Using JavaScript:
Grab the url of the link and add a button which, when onclick'ed, points the browser to that url. Then add display:none to the original link with CSS.
You can also use an image as Colin says, but that would fake a button and I assume you want a real button.

YOu could try to render it using an Image, as stated here
The LoginStatus control displays either a text or an image link, depending on the setting of the LoginImageUrl and LogoutImageUrl properties. You can display either text or images for one or both states.

Cheers, I will have a look into this :)
I think it's strange that the option of turning it into a button is not already available.

You could wrap the LoginStatus inside of a LinkButton (Or any kind of button).
<asp:LinkButton id="LinkButton1" runat="server">
<asp:LoginStatus id="LoginStatus1" runat="server" />
</asp:LinkButton>
then use the LinkButton1 events.

You could always just extend the LoginStatus control by creating a derived class, and overriding the rendering behaviour to change the output elements into your desired elements, or add style attributes, or whatever.
(apologies for VB)
Public Class MyLoginStatus
Inherits System.Web.UI.WebControls.LoginStatus
Public Overrides Sub RenderBeginTag(ByVal writer As System.Web.UI.HtmlTextWriter)
writer.AddStyleAttribute("display", "none")
MyBase.RenderBeginTag(writer)
End Sub
End Class
This kind of behaviour could be extended to turn the output into a button, if you so wish, either in aggregate (modifying the final rendered output by creating your own HtmlTextWriter enclosing a StringWriter and invoking the base methods), or by injecting your own behaviour into the relevant render events.

Have you looked into Control Adapters - this allows you to alter the HTML generated. It's primarily used for adapting HTML for different browsers and devices, but can be used to have complete control over server controls.

I know this is an old post but I'll chime in.
Here's a very simple way to make a button out of the LoginStatus control. Set the control CssClass to a bootstrap button and your good to go. Whatever text you have for the login and logout will go into the button.
<asp:LoginStatus ID="LoginStatus1" runat="server" CssClass="btn btn-primary" LogoutPageUrl="yourlogin.aspx" />
