Hi,
me: ASP.NET newbie, know a lot of C# though
Situation: I have a Visual WebDeveloper project going (C#). In the default.aspx I have a table with an embedded Google Maps item (javascript). a listener gets variables latitude and longitude from Google Maps and the script puts them in the asp labels succesfully.
Problem: button1_click reloads the whole page and I loose my updated label.text; I want to retrieve the text in the labels so that I can use them in the default.aspx.cs
help?
thanks

use ViewState For that !!!
when you are click on Button... Postback is performed and that refresh the control.

EnableViewState = true / false? Doesn't really make any difference.
That's all that I know about ViewState. Must I do something with the PostBackUrl? Sorry, I am really new to webapplications.

Are you setting the initial text in your page load? Try an if not IsPostBack.

Enabling viewstate will not solve ur problem as label values are lost when set by javascript. Use readonly textboxes or simulaneously put ur values in a hidden field when u set then in a label and use those hidden fields values when required...

hi all,
I have a sample website (virtual directory name : "switchTestSite") and have another one (virtual directory : "innerSecuredSite") as a child of "switchTestSite". The "innerSecuredSite" is secured with SSL and is supposed to run with https:// only. I have selected "Require secure channel(SSL)" in directory security with "accept client certificate" selected.
But the parent directory "switchTestSite" is accessible through http, i.e. Require secure channel is not selected here.
A button in "switchTestSite" redirects page to "innerSecuredSite"
expected result:
in IE when I navigate to "innerSecuredSite" directly with http, browser should ask for https://
observed result:
IE does not ask for https, rather it navigates to "innerSecuredSite" default page directly.
another observations.
when I try to browse the virtual directory "innerSecuredSite" from IIS, it asks me to use https://
(can someone help me out. or if i am missing something)

I won't post the code, because I don't have it handy... but here's how you do it.
Create a blank user control.
Change the inheritance from "UserControl" to HyperLink
public partial class MyWebUserControl : HyperLink

Hi to all,
I am sending an email by using VB with ASP.Net. The code is as follows...
MMsg = New MailMessage
MMsg.From = GetUserEmail()
MMsg.To = txtto.Text
MMsg.Subject = "Invitation...!"
MMsg.Body = Invitation
MMsg.Priority = MailPriority.High
SmtpMail.SmtpServer = "MyServername"
SmtpMail.Send(MMsg)
it works fine whenever running this on local network but it shows an runtime error after publishing on web. The error messsage is as follows...
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customerrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customerrors> tag should then have its "mode" attribute set to "Off".
Anybody can help why this error occurs?
Thanks

Probably your mail server is not configured properly or you have used incorrect reference to it
When you fail to plan, you are planning to fail.
|
|
|
|
|
If you go into the web.config and set the attribute described to Off, then you get to see the actual error message...

yes i know that. but i want to why this error is occured. it works fine in intranet.

try an intelligent header, everyone here wants ASP.NET help, or is in the wrong forum
One guess, do you want selectedvalue, or selectedText ? Try setting a breakpoint and seeing which property contains the data you need.
Of course, this code is incredibly nasty, I hope no-one is paying for this, and you're just learning ? You should never have database code like this sitting inside your codebehind, it's a maintenance nightmare.

Hi
I am using asp.net 3.5 , Its my first ever experience that I am building a site which could hold millions of records and 1000's of users can sign in togather, This application is some thing like property real estate. Now the problem which I am facing is the following.
Since application could have millions of records and millions of users navigating togather with in the application so what should be the development architecture.
If I shall use web service as Bussiness Layer then we need to place to hostings one for service and other for main application where we want to deploy single application on IIS to use this as a product in future. Also if I shall keep the webservice then on each user login or each query system will open a new connection with SQL server which would kill SQL server.
If I keep a Bussiness Tier in the middle ( like Transaction Server) even then connection to SQL Server will go to millions when million of users will sign in togather.
I dont understand what should be the best as I am just working on this issues now a days to define architecture well before starting development.
Any Suggestions or any links which could help me would be highly appreciated.
You can consider zillow.com as a type of project I am going to work on.

Our company runs a web site with fairly high load. At high tide it goes up to about 400 requests per second.
We have two load balanced web servers, and one database server. The web servers doesn't work very hard, though. At top load they reach 4% CPU usage...
It's a three tired application, but the business layer is part of the application running on the web servers, so there is no physical separation between the presentation layer and the business layer.
Rizwan Bashir wrote: on each user login or each query system will open a new connection with SQL server which would kill SQL server.
There is hardly any risk for that. The database connections are pooled in .NET, so most of the time you will recycle an already open connection instead of establishing a completely new connection.
If you just try to minimise the time that you use the connection (open late, close early), each page will use a connection only a few milliseconds, so the server can produce a whole lot of pages per second with only a few connections in the pool.
However, to reduce database load you can use caching in the web application. We cache search results (lists of item id:s) and items (cars), so some pages are created without the need to call the database at all.
Despite everything, the person most likely to be fooling you next is yourself.

Hi
Thanks for the reply and it gives me real comfort that I was thinking in right direction. I was also planning for Bussiness Layer which could be deployed separately and with project depending on the requirement.

hi,
i want to run a script on page load. the page is included in a masterpage contentplace holder.
eg.
<pre>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<script language="javascript">
obj=(document.all) ? document.all['<%=pnlOptPro.ClientID %>'] : document.getElementById('<%=pnlOptPro.ClientID %>');
obj.style.display=(obj.style.display=='none') ? 'inline' : 'none';
obj1=(document.all) ? document.all['<%=pnlUsrwise.ClientID %>'] : document.getElementById('<%=pnlUsrwise.ClientID %>');
obj1.style.display=(obj1.style.display=='none') ? 'inline' : 'none';
</script>
</asp:Content>
</pre>
the code which is in the script has to be run when this page is loaded. but this does not happen??

Try writing it as a function and registering it with the body onload event. More likely than not the script is running but the page hasn't finished loading yet.
