Check in the last example, I am using AJAX to get the XML data from the server. Just replace the XML datasource with your appropriate data.

It is very easy to do that, I have done that lots of time.

Other than that, you can also place the retrieved points in some hidden field and place markers in the pageload.

Hope you got it. Thumbs Up | :thumbsup:

How to handle request validation exception

Hi All

I have the following code

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<script language="C#" runat="server">

protected void button1_Click(object sender, EventArgs e)
{
try
{
TextBox1.Text = (TextBox1.Text + "<strong></strong>");
Label1.Text = (TextBox1.Text);
}
catch (System.Web.HttpRequestValidationException)
{
Response.Write("html is not allowed");
}
}

</script>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" Height="300px" Width="400px"></asp:TextBox>
</div>
<asp:Button ID="button1" runat="server" Text="strong" onclick="button1_Click" />
<asp:Label ID="Label1" runat="server"></asp:Label>

</form>
</body>
</html>

If i click on button twice I am getting request validation exception which I want to catch.

The error which I am getting is

*************************************************************************

Server Error in '/TextControlOnSite' Application.

A potentially dangerous Request.Form value was detected from the client (TextBox1="<strong></strong>").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.

I have put try catch block but it is not executing.
I know that we can use Server.HtmlEncode and Server.HtmlDecode method and also knows that ValidateRequest property of page attribute.But in my case i want to execute some code only on this page when the RequestValidation Exception occurs.
I donot want to handle error in global.asax file.
I want to handle error on this page only.

Please suggest.

Thanks

Sandeep

The solution is present in your exception itself.

put validateRequest="false" in your <%@ Page directive

This will solve your problem.

Try google and you will know why this exception occurs while posting back.

Why do you want to catch exception at server side.. you can do it by custom validator also

but if you want to do it server side only... put ValidateRequest="false" in page attribute.. Now .Net allow this request to go server side.Now make your handler to throw some exception according to your need and show the message accordingly..

I am writing a code which send Email to the respective email address. First time its working fine. But after sending my first email its not accept my program and I am not able to send email again. I put the code snippet here.

Dim smtpServer As New SmtpClient
Dim messageSTR As New MailMessage
Dim strAddress As New MailAddress("Email address", "Name") 

messageSTR.From = strAddress 
messageSTR.To.Add("To Email Address")
messageSTR.Subject = Me.txtSub.Text
messageSTR.Body = Me.txtMailBody.Text

smtpServer.Host = "smtp.gmail.com" 
smtpServer.Port = 578 

smtpServer.Credentials = New NetworkCredential("user id", "user pass")

smtpServer.EnableSsl = true
smtpServer.Send(messageSTR)

What is the problem? Why I don't send the second mail?

Exception Shown: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 209.85.129.109:578.
Error Message: Unable to connect to the remote server

Hi,
I have a project requiement to build a facebook like website in C# & ASP

In this website:
- Allow at least 3 types of users: unregistered visitor, registered user and moderator
- Allow users to create profiles and upload images etc.
- Any user can search for people and view public profiles
- Registered users can create a profile which can connect with other members or groups of people can join. Each user can set their profile : public or private.
- Each user can add albums with pictures. Every picture may receive comments from friends or from other users which the user can accept or reject
- The user has one mailbox that can communicate with other members of the site.
etc etc

I am a novice when it comes to coding, I have so far been able to create profiles and allow uploading of images and returning but I seem to be lost at doing stuff like retrieving a user's images when his profile picture is clicked etc etc. Are there any references you guys could point me to that would give me more information on developing this. I like doing things on my own but would be useful if I could refer to a source for more info when I got stuck.

Thanks so much for helping!

Kool

Controls property on a Page gives all child controls. Is that what you are looking for?
