Hi,
I want to have Session in Global.asax file.
I had declared in global.asax.cs
like
void Application_Start(object sender, EventArgs e)
{
string strUser = HttpContext.Current.Session["USER_NAME"].ToString();
}
It says object reference not set.
I had tried by giving HttpContext.Current.User.ToString(),that also did not work out.
Also on Session End i want to end or Dispose the Session.
This Session variable must be accessible throughout the web application.
Please help.............
Thanks

Application_Startup is called when the application itself starts (or re-starts if it has stopped after going idle) and is unrelated to a particular user session, so is the user stuff in uninstantiated. This would be the method you'd call to log at what times the application starts and re-starts for example.
It looks very likely that you need is to move this code to the Session_Start method, this is called the first time a user starts a session. The current user object is available at this point, as is the Session property.
void Session_Start(object sender, EventArgs e)
{
string strUser = HttpContext.Current.Session["USER_NAME"].ToString();
}
If the user were available in application startup, only the user who started the application would have their username set!

Hey!
I have been trying several times to fix it but couldnt find correct codes in C#. You can copy all these below codes of markup and C# so that you will see what is problem. Im fine with markup but only problem with C#. There is some explanations (bold and underline) below. Your help will be highly appreciated. Thanks so much for your time  Looking forward to hearing from you!
Markup:
<form id="Form1" method="post" runat="server">
<label><asp:TextBox ID="txtName" runat="server"></asp:TextBox>Name:</label>
<label><asp:TextBox ID="txtEmail" runat="server"></asp:TextBox>Email Address:</label>
Order the following cards:
<asp:ListBox name="order" Runat="server" ID="dlist1" SelectionMode="Multiple" onchange="swapImage1()">
<asp:ListItem>SOW SEEDS OF LOVE</asp:ListItem>
<asp:ListItem data-card="R 32.00" data-memo="R 62.00" Value="Images/Bday.jpg">Birthday</asp:ListItem>
<asp:ListItem data-card="32.00" data-memo="62.00" Value="Images/Wedding.jpg">Wedding</asp:ListItem>
</asp:ListBox>
Display prices when clicked an item on listbox control:
<script type="text/javascript">
window.onload = function()
{
document.getElementById("dlist1").onchange = function() {
var option = this.options[this.selectedIndex];
document.getElementById("price_card").innerHTML = option.getAttribute("data-card") ? option.getAttribute("data-card") : "";
document.getElementById("price_memo").innerHTML = option.getAttribute("data-memo") ? option.getAttribute("data-memo") : "";
}
}
</script>
Display image when clicked an item on this ListBox control (above):
<div>
<asp:Image ID="imageToSwap1" runat="server" width="147" height="195" ImageUrl="" />
</div>
<script type="text/javascript">
function swapImage1() {
var image = document.getElementById('<%= imageToSwap1.ClientID %>');
var dropd = document.getElementById('<%= dlist1.ClientID %>');
image.src = dropd.value;
};
</script>
1) After choosing an item (birthday card) on ListBox control, then you decide to choose "card A6" on input control using checkbox but you also choose another item (wedding card) on ListBox control, so you also choose "memo book" (only for wedding card)
2) Look below (bold) -- id="price_card" and id="price_memo" are implemented by Javascript to display several price
<table>
<tr>
<td input type="checkbox" name="description" value="Card A6" id="description1" runat="server" /> Card A6 (blank)</td>
<td id="price_card"></td>
</tr>
<tr>
<td input type="checkbox" name="description" value="Memo Book A6" id="description2" runat="server" /> Memo book </td>
<td id="price_memo"></td>
</tr>
</table>
For example: if you wanna order two cards (card A6 for birthday card and memo book for wedding card), then clicking on send button to send this data to my gmail account:
<asp:Button ID="Send" runat="server" Text="Send Email" onclick="Send_Click1" />
</from>
I have no problem with this markup but have a little problem with codes (C#). After you sent order data to my gmail account, I will get your email and can read this data what you wanna order.
This order data should be displayed on email: (thats what I want)
Name: xxx
Email Address: xxx
Order 1: Images/Birthday.jpg
Description 1: Card 6
Order 2: Images/Wedding.jpg
Description 2: Memo Book
My current problem:
Name: xxx
Email Address: xxx
Order 1: Images/Birthday.jpg (no display)
Description 1: Card 6 (display) - fine
Order 2: Images/Wedding.jpg (no display)
Description 2: Memo Book (no display)
Im struggling with codes in C# - look at below and you can test these codes (copy) to receive your email on your gmail account after clicking on send button. You will see some order data is missing:
protected void Send_Click1(object sender, EventArgs e)
{
string msg = "---------------------------<br>";
string from = "youremail@gmail.com";
string to = "youremail@gmail.com";
MailMessage mail = new MailMessage();
mail.To.Add(to);
mail.From = new MailAddress(from, "Ellie Rose", System.Text.Encoding.UTF8);
mail.Subject = "Customer Order from Ellie Rose Website";
mail.SubjectEncoding = System.Text.Encoding.UTF8;
msg += "Name: " + txtName.Text;
msg += "<br>Email: " + txtEmail.Text;
if (description1.Checked == true) //Card A6 - need to display data on email - not working
{
msg += "<br>Description 1:" + description1.Value;
msg += "<br>ORDER 1: " + Request["order"];
}
if (description2.Checked == true) //Memo Book - need to display data on email - not working
{
msg += "<br>Description 2:" + description2.Value;
msg += "<br>ORDER 2 : " + Request["order"];
}
mail.Body = msg;
mail.BodyEncoding = System.Text.Encoding.ASCII;
mail.IsBodyHtml = true;
mail.Priority = MailPriority.High;
SmtpClient client = new SmtpClient();
//Add the Creddentials- use your own email id and password
client.Credentials = new System.Net.NetworkCredential(from, "yourpassword");
client.Port = 587; // Gmail works on this port
client.Host = "smtp.gmail.com";
client.EnableSsl = true; //Gmail works on Server Secured Layer
try
{
client.Send(mail);
}
catch (Exception ex)
{
Exception ex2 = ex;
string errorMessage = string.Empty;
while (ex2 != null)
{
errorMessage += ex2.ToString();
ex2 = ex2.InnerException;
}
HttpContext.Current.Response.Write(errorMessage);
} // end try
}

No one is going to read this huge mess of unformatted garbage let alone copy it and run it for you.
Please review the posting guidelines and format any code snippets. Also, only post the relevant code, NOT ALL. And, fully describe your expected results, problems encountered and any attempts you have made.

Hi,
Anyone know how to convert ASP.NET code to HTML at runtime. like it do in the VS IDE(Source to Design).
when i entered some code like below to a text box and click a button
<asp:button id="Button1" runat="server" text="Button" onclick="Button1_Click">
it should convert it to html and render the button.
I simply need something like this (try it yourself in w3schools)
http://www.w3schools.com/html/tryit.asp?filename=tryhtml_button[^]
instead of HTML code there I need to create a site in ASP.NET which user can input ASP.Net code and get the output
Thanks in advance

well;
your button is rendered as
<input type="submit" id="Buttun1.ClientID" name="Buttun1.UniqueID" value="Button" />
onclick="Button1_Click" has nothin to do with the client(HTML) it runs at server
if you add UseSubmitBehavior="false" to the button the render will be
<input type="button" id="Buttun1.ClientID" name="Buttun1.UniqueID" value="Button" onclick="javascript:__doPostBack('Buttun1.UniqueID','');" />
__doPostBack() function assigns its first parameter to the hidden field __EVENTTAARGET and the second to __EVENTARGUMENT and submit the form. In case ...etc.
this is so much for a button, isn't it?
the easiest way is to save the code on the server then run it.
Help people,so poeple can help you.

<asp:button id="Button1" text="Button">

text += "<asp:Content ID=\"BodyContent\" runat=\"server\" ContentPlaceHolderID=\"MainContent\">";
text += TextBox1.Text;
text += "</asp:Content>";
sw.WriteLine(text);
sw.Close();

Well done, Sir;
I am sorry because I left the thread, but i think i should tell you some thing about forums.
When you want to discuss with someone, you should click 'Replay' under his message but not yours, so an email message would be delevered to him.
In our case I didn't know about your next question, because you replayed yourself instead of replaying me.

I have a page that has a tab control and currently contains two tabs. The first tab contains information about students (name, address, phone #, etc.) and most of the text boxes have either a regex, required field (or both) validators with a validation group name of StudentInfoVG. There is also a button used to update the student information with a validation group name of StudentInfoVG.
The second tab, which has information about the students grade and performace, has an editable grid view bound to a SQL data source and some of text boxes in the edit item template have only a required field validator. These have a validation group name of GradeVG. The grid view also has a command field to enable the editing of a row also with a validation group name of GradeVG:
<asp:CommandField ButtonType="Button" ShowEditButton="True" ValidationGroup="GradeVG">
<ControlStyle Font-Size="11px" />
<ItemStyle Font-Size="11px" />
</asp:CommandField>
I can update the student information and grade information fine, but if I do the following steps in order:
1. Start on the first tab (student info.)
2. Go to the second tab (grade info.) and click the edit button to enable editing of a specific row
3. Click the now visible cancel button to cancel the editing
4. Go back to the first tab (student info.)
5. Change a field (for example the student's city)
6. Click the update button to update the student information
The student's information does not update. I even set a break point on the method that handles the update buttons click event and it does not fire. However, if I do all the steps but instead of changing a field I leave a required field blank I get a message in the validation summary. So in the previous example, if I left the student's city blank the validation summary would say "Student's city required." This indicates to me that validation is being performed, and in the above example the validation passes since I get no error message, but the click event is not "fully" firing.
Any suggestions on why everything works fine except when I go to edit a row on the second tab panel and cancel it. It seems that the update button on the first tab is doing validation on the items in the second tab even though they are in different validation groups. Am I missing something here or is this just some weird quirk of tab containers and validation? I've been trying to tweak this for several hours with no luck so any help or suggestions would be greatly appreciated. Thanks in advance for any help you can provide.
**UPDATE**
I have been trying to narrow down exactly when the button loses it's ability to update the student info and it has nothing to do with the grid view on the second tab panel; it has to do with the tab panel itself. If I do the following steps in order the same results occur (where the update button's method will not fire):
1. Start on the first tab (student info.)
2. Go to the second tab (grade info.) and do not do anything
3. Go back to the first tab (student info.)
4. Change a field (for example the student's city)
5. Click the update button to update the student information

Hello,
For one project, can we have a part of it as web app and a part as web site? Is there any special set up that needs to be included?
What I have found is that compiling a web app is taking a long time, to see the code behind changes.
Thanks!

No, you cannot. A project can either be set up as a website or as a web application.

<asp:TextBox ID="txtExchangePartQty" runat="server" onfocus="if(this.value==this.defaultvalue) this.value='';" value="Quantity..." Width="120px">
</asp:TextBox>
<asp:FilteredTextBoxExtender ID="ftbeQty" runat="server" TargetControlID="txtExchangePartQty" ValidChars="1234567890" />
When I dont use FilteredTextBoxExtender, as an initial value, inside the texbox "Quantity..." appears but when I use FilteredTextBoxExtender during the loading of the page, for a moment I see that initail value but then it dissappears.
The cause is for it is TheFilteredTextBoxExtender, any idea why this is happening and how can I work out this problem?
