To handle special characters,you can use javascript functions escape() and unescape() to encode and decode.this will allow to display the special charactersCheers!!

Just, set the HtmlEncode property of your BoundField to False.
Like:
<asp:boundfield datafield="Character" headertext="Character" htmlencode="false" />
</asp:gridview>

Hi All,
I need to implement on my form, a feature to automaticaly store the old value of the cotnroles on a database if the user press a button to save the value. One way is to code it for each control on the ButtonClick event but it's too heavy to do and no fearly nice.
So, a good way is to declare inherited controls, add properties and declare events. On the form, when the user press the button, raise the event and for each control whose has the value changed and saved it to disk.
I need also to pass arguments on the Event to stored it on the database.
I have implemented the following but the event on the custom controls is not fired. So I do not know what is wrong.
First:
On the /APP_Code subdirectory, I have created a class called "MyControls" like this:
namespace MyControls
'need this class to customize argumentso to pass in tge event
Public Class SaveEventArges
myproperties...
End Class
Public Delegate Sub SaveEventHandler (ByVal sender As Object, ByVal e as SaveEventArgs)
Public Class ComboBox
Inherits .....
myproperties and methods ...
Public Event Save as SaveEventHandler
Protected Overridable Sub OnSave (ByVal sender As Object, ByVal e as SaveEventArgs)
RaiseEvent Save(me, e)
End Sub
Protected Sub ComboBox_Save ( ByVal sender As Object, ByVal e as SaveEventArgs) Handles Me.Save
mySaveCode
End Sub
End Class
end namespace
Second: On my form
<%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb" Inherits="_Default" >
<%@ Register TagPrefix = "mc" Namespace = "MyControls" %>
...
<mc:combobox runat="server" id="TextComboBox" ><="" mio:combobox="">
<asp:button runat="server" id="Btn" text="Press">
....
On the code behind:
Imports MyControls
....
Public Event Save As SaveEventHandler
Protected Sub Btn_Click ....
Dim t as New SaveEventArgs
my t... properties to pass to the event
RaiseEvent Save (me., t)
End Sub
What am I doing wrong?
I spent 4 days reading how to do it and no way to found a solution, so please i need your help.

I have bulk of data of client information aprox 15000. When I Fill this data to GridView it takes too much time.
1. Fill data with sqldatasource.
2. Fill datatable and bind with GridView.
To fill data with datatable to get data I use this code -
SqlConnection cnSql = new SqlConnection(strConn);
cnSql.Open();
SqlCommand cmd = new SqlCommand(StrSql, cnSql);
cmd.CommandTimeout = 50000;
cmd.ResetCommandTimeout();
SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);
is there any problem with my code or I have to change some configuration in my web.config ?

This is not an good idea to showing this amount of data In gridview at time.
What you can do
1. Use Filter Criteria and based on that allow to retrieve Data. Because, there is no sense to load 15,000 at a time, as no one going to check those data at time.
So, use filter criteria.
2. Use Caching, To Reduce the performance hit. If the data is common for all user, use dataCaching, use filter from Cached data itself. Use Cache Dependency if you want to update cache if some changes in data.
Hope this will help you !

Apart from Abhijit's suggestion you may also wish to consider one or more of other methods of displaying data. Some of them are: Paging, Grouping of Records, Pivoting, or using Graphs or charts.
The main idea is just don't dump a lot of data to the client browser. Secondly, user can analyse the data if the number of rows are lesser.

| As Anurag & Abhijit suggested,use some filter criteria.If there is no criteria then use paging.Also it'll be better if you do the paging at databse level itself. Cheers!!

I am not sure about the code, but just asking which browser you are using? ActiveX Control works only in IE Browser.

Hello,
i have code to send smtp mail from local system and from configured server.
when i use to send email with all options like from,to,cc and bcc as per the below code
local server(system code works like)
Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration("~/Web.config");
MailSettingsSectionGroup mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;
if (mailSettings != null)
{
port = mailSettings.Smtp.Network.Port;
host = mailSettings.Smtp.Network.Host;
password = mailSettings.Smtp.Network.Password;
username = mailSettings.Smtp.Network.UserName;
}
MailMessage message = new MailMessage(FromAddress, ToAddress, EMailSubject, EMailBody);
if (string.IsNullOrEmpty(ToAddress))
{
message.To.Clear();
message.CC.Clear();
}
else
{
message.CC.Add(ToAddress);
message.To.Clear();
}
if (!string.IsNullOrEmpty(BccAddress))
message.Bcc.Add(BccAddress);
message.IsBodyHtml = IsHTMLFormat;
SmtpClient mySMTPclient = new SmtpClient(host, port);
NetworkCredential userCredetials = new NetworkCredential(username, password);
mySMTPclient.UseDefaultCredentials = false;
mySMTPclient.Credentials = userCredetials;
mySMTPclient.EnableSsl = true;
mySMTPclient.Send(message);
then it is working fine.
from the above code all the mails will be sent from one singe from address like "abc.gmail.com" irrespective of from address at runtime.
from the hosting server
to accomplish this i have used code as below
System.Web.Mail.MailMessage mailMessage = new System.Web.Mail.MailMessage();
mailMessage.From = FromAddress;
if (!string.IsNullOrEmpty(BccAddress))
{
BccAddress = BccAddress.Replace(",", ";");
mailMessage.Bcc = BccAddress;
}
if (!string.IsNullOrEmpty(ToAddress))
{
ToAddress = ToAddress.Replace(",", ";");
mailMessage.Cc = ToAddress;
}
mailMessage.Subject = EMailSubject;
mailMessage.Body = EMailBody;
if (IsHTMLFormat)
mailMessage.BodyFormat = System.Web.Mail.MailFormat.Html;
else
mailMessage.BodyFormat = System.Web.Mail.MailFormat.Text;
mailMessage.Priority = System.Web.Mail.MailPriority.Normal;
System.Web.Mail.SmtpMail.SmtpServer = "127.0.0.1";
System.Web.Mail.SmtpMail.Send(mailMessage);
mails will be sent from the user who ever sends.
but the problem is what ever email have added to Bcc are not sent and rest from and cc are working fine.
this is very important to me because we intend to stop release because of this.
any solution would be highly appreciated.

Can you please Reformat your code ?
Please put your code inside CODE Block Or PRE Tag. Like below,
Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration("~/Web.config");
MailSettingsSectionGroup mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;
if (mailSettings != null)
{
port = mailSettings.Smtp.Network.Port;
host = mailSettings.Smtp.Network.Host;
password = mailSettings.Smtp.Network.Password;
username = mailSettings.Smtp.Network.UserName;
}
Which makes the question clear and easily readable. Its very much confusing to check your code and your problem statement inside your code block.
Thanks !

There are tow ways to stroe the images.
One way,save the image in local hard disk and save the path of the image in database.
else, Save the image in byte array format in database but this makes the database heavy.
Have a loook to this LinkCheers!!

In our site I am trying to integrate the CITI Bank payment gateway .For canceling a payment we need to send the post request from merchant site to payment gateway site .For this I am using the web request method , I am posting the parameters to the payment gateway server using the web request but not getting the web response , it is giving the error as The remote server returned an error: (500) Internal Server Error . I am not understanding whether the problem is with the web request or I am not sending the request properly to the gateway . Can anyone please let me know is there any other way to post the request from server to server other than web request method .
Thanks in advance
