Friends

I had developed an small website in visualstudio 2008
and I had problem in Deployment of that site..

steps:
1.I installed IIS server
2.registered asp.net
3.Created virtual directary and placed in that folder

It is working in One System with

URL:http://localhost/home.aspx

I want that site to be run in the LAN systems

I am using XPsp2

came out of hardwork

What is your problem exactly ? If it has to run on the LAN, just replace localhost with the name of the machine. You understand what 'localhost' means, right ?

Its means its working in the machine where you have deployed. Now Try to access it from other machine with the IP Address of the deployed system like http://192.192.192.192/home.aspx
Make sure that system should have the same LAN.

BTW : one question, you have wrote you have create the Virtual Directory, What is your Virtual Directory name? If you have the Virtual directory you should access it from http://localhost/<Virtual Directory>/Home.aspx Or you are redirecting your site from Root to any where? Confused | :confused:

You say you have SQL Server 2008 enterprise, yet your connection string is for SQLEXPRESS. Is your SQL Server 2008 a named instance, named SQLEXPRESS ?

Can I expand an ajax collapsiblepanel from a button in a different user control?

I have 2 user controls:

-1 contains my collapsiblepanel control.

-My other contains a button I want to click to expand my collapsiblepanel

How can I pass the value of my button click in my 2nd user control over to my collapsiblepanel in my 1st user control?

Can this even be done?

Thanks.

In your designer.cs file (if it is a webapplication) you can change the protected global:: into public global:: for you button.

In that case the OnClick Event can be reached from your second control.
In your second control you add

Control1.fromOhterControl.OnClick += new EventHandler(fromOhterControl_OnClick);

and you create the method
protected void fromOhterControl_OnClick(object sender, EventArgs e)
{
}

That should work

In Word you can only store 2 bytes. That is why I use Writer.

Menu Items on hover clickable area

Hello everyone! I have an asp:menu item in which the background color changes during a static and dynamic hover style. Everything looks great, however I have noticed that many of my users are mislead into thinking the whole area is clickable when in reality the anchor will only work if the mouse is over the text of the link. Is there a trick to changing the clickable area to take up the whole "background" that is changing rather than just the text? I've googled around but can't seem to find what I'm looking for.
Thanks in advance!

It sounds like you need a CSS fix for this. Here's some code I have for a CSS button. I'm not a css expert, but I believe it's the "display:block;" that does what you're looking for:

ASPX:
<asp:Hyperlink ID="lnkDefaultButton" runat="server" CssClass="defaultButton" Text="Button" Width="200" Height="20"/>


CSS:
a.defaultButton { background-color:white; width:200px; height:20px; display: block;outline: none;}
a.defaultButton:hover { background-color:black; width:200px; height:20px; display: block;outline: none;}

Does this work?

Hi Goalie35,

no, that didn't seem to do the trick. I'm wonder if there's something within the asp:menu item that's overriding the css class?

<pre> <asp:Menu ID="Menu1" runat="server" DataSourceID="siteMapDataSource"
DynamicHorizontalOffset="2" Font-Names="Tahoma" Font-Size="11px"
StaticSubMenuIndent="10px" style="background-color: transparent;
font-weight: bold; vertical-align: top; margin-bottom:30px;
background-image: url(/designElements/interfaceImages/menubkg_new.jpg);"
Width="152px" ForeColor="#666666" DynamicEnableDefaultPopOutImage="False"
DynamicPopOutImageUrl="~/designElements/interfaceImages/menuarrow.gif"
StaticPopOutImageUrl="~/designElements/interfaceImages/menuarrow.gif" Height="275px"
CssClass="pointer" EnableTheming="False">
<DynamicHoverStyle BackColor="#8E8E8E" ForeColor="White" />
<DynamicMenuStyle CssClass="adjustedZIndex" BackColor="#D1D1D1" />
<DynamicSelectedStyle BackColor="#D1D1D1" />
<DynamicMenuItemStyle HorizontalPadding="5px" VerticalPadding="5px" />
<StaticMenuItemStyle HorizontalPadding="5px" VerticalPadding="3px" ItemSpacing="1px" />
<StaticMenuStyle BackColor="#D1D1D1" />
<StaticHoverStyle BackColor="#8E8E8E" ForeColor="White" CssClass="pointer" />
</asp:Menu>

the pointer cssclass just has cursor: default; in it, but that's where I was adding the display:block and then creating a.pointer{ display:block;} but still not doing the trick.

Hi,

I created a Virtual directory for my web site. Now I want to publish it at http;//localhost/test2. How can I do that.

Re: publish web site

Abhishek Sur2-Jun-09 10:59

http://localhost belongs to default port 80, so just install IIS and right click on the Default WebSite of the IIS console and make one virtual directory named test2.

Now publish your website to the folder you choose.

You also need to configure your website a bit.

http://www.codeproject.com/KB/aspnet/VSDeploy.aspx[^]

might help you...

Yes, I created the virtual folder. e.g my website is in the folder C:\project\NyWebSite

Now I treated virtual folder in C:\Project and named it as test2. But when I go to window explorer C:\project my test2 is not there. So,. How can I publish it. I have no idea where I am doing wrong

test2 is virtual directory name. It will not exist physically. It is referring to location C:\project and that will be the root of your website. Copy/publish all your files to this location.

If you are using ASP.NET 2.0 or above, just copying all files to this virtual directory will work. VS provides several publish options which can also be used. Refer to MSDN for using the publish feature.

I don't understand what are your doing? If you have published your Web sites from VS, then Open IIS and Create the Virtual Directory and Give the Path Reference of your Published Folder, that all. Now you can access from you web site from Localhost or IP address.

web.config values before install

I am developing an install package for the web application (ASP.NET, VS 2008, C#) using "Setup and Deployment" project in VS 2008.
When the user is upgrading the application (by installing the next release), I need to save the web.config file to restore some settings from the previous install.
How do I do this ?

Well, you need to write some logic for this. You may take a look at Custom Actions and use an installer class to read the previous web.config before it is overwritten by the new file. Rose | [Rose]
