ASP.NET

Hi
I have the following code:

for (int x = 0; x < GridView1.Rows.Count; x++)
{
dropdown.SelectedItem.Selected = false;
Session["default"] = GridView1.DataKeys[x].Values[2].ToString().Trim();
string default = Session["default"].ToString().Trim();
dropdown.Items.FindByValue(default).Selected = true;
}

What it should do is find the value in the session default and then set the dropdown to that value.
However it only seems to be doing it to the last row instead of all of them
why would this be?
cheers!

Nope thats not working either.
Basically Ive got a gridview with say 9 rows in
each row has an order of what it would be so the order column should look like this

order
1
2
3
4
5
6
7
8
9

but its not, after adding your line of code it is now displaying 1 in all the dropdowns except the last one which is 9.
Why would this be?
thnaks! Smile | :)

You must find the dropdown to set the value.

Hop this will help! Smile | :)

Generally, this error is thrown when the trust level of an applicaiton is set to medium.
You may use web.config to edit the trust parameter (make it "Full") and then everything should be working.

I would like to dynamically change an asp.net web page. This should be done only by an admin and the change should be permanent. I've found alot of tutorials on how to add controls to the same web page, but this was done by everyone and the change was done for the same session and not saved for the next.

Here is a very simple to do it:

SmtpClient client1 = new SmtpClient("smtpserver", 25);
MailMessage msg = new MailMessage();
msg.To.Add(new MailAddress("toemailaddress"));
msg.From = new MailAddress("fromEmailAddress");
msg.Subject = "Test Message";
msg.Body = "Test Mail with Attachments";
Attachment item = new Attachment("D:\\test.txt");
Attachment item1 = new Attachment("D:\\test2.txt");
msg.Attachments.Add(item);
msg.Attachments.Add(item1);
client1.Send(msg);
Response.Write("Send");

Hi All,

I am using basepage in my ASP.Net code but in base page I am not getting session.
My code is as follows:
public class DD_AdmBasePage : System.Web.UI.Page
{
public string LoginUser;
public DD_AdmBasePage()
{
LoginCheck();
}

protected void LoginCheck()
{
if (HttpContext.Current.Session["LoginUser"]!=null)
{
LoginUser= HttpContext.Current.Session["LoginUser"].ToString();
}
else
{
HttpContext.Current.Response.Redirect("~/login.aspx");
}
}
}

please help me, I am getting error in following line:
if (HttpContext.Current.Session["LoginUser"]!=null)
error: object reference not set to an Insatance.

and when i am checking HttpContext.Current.Session, it is showing that it is null. I cant understand why it is null.

Please help me.

Because you base page has stopped calling "OnInit" on it's base page which is "System.Web.UI.Page". So always override it

public class DD_AdmBasePage : System.Web.UI.Page
{
     public string LoginUser;
     
     public DD_AdmBasePage()
     {
         LoginCheck();
     }

     protected void LoginCheck()
     {
         if (HttpContext.Current.Session["LoginUser"]!=null)
             LoginUser= HttpContext.Current.Session["LoginUser"].ToString();
         else
             HttpContext.Current.Response.Redirect("~/login.aspx");
     }

     protected override void OnInit(EventArgs e) {
          base.OnInit(e);
     }
}

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Then you are doing something wrong. See the ASP.NET page life cycle[^] and "Init" is called at the beginning. Can you post the whole base class code ?

Can you show your derived Page ?
Are you using OnInit event in that page?

Thanks and Regards

InitializeComponent();
base.OnInit(e);

Seems to be tricky. Can't guess from this also

protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
Check this
