Hi Commickey,
Set autopostback property to that dropdownlist is true in the property window.
When ever you select a item in the drop down listbox, dropdown box index changed event will be fired. You write code to dispaly that row details in the tables.
double click on the dropdown box in design time you will get event function, write the code in that funcnction,
I guess it will work for you

Thanks & Regards,

A more elegant method would be to use AJAX - no need for postbacks (bleuuuugh!)

I have 2 pages that validate (using validation groups) the users inputs and store them in a cookie. The first page validates and puts the in a cookie, then redirects the user to a second page where the values from the cookie are read, modified then written (overwrites the former value) in the cookie.
The code for the two pages resembles, here is a sample:
String t, s,t1;
int i = 0;
s = "";
t = "";
if (Page.IsValid)
{
t = GetCookie("test");//reads the value from the cookie possible place where the error lies.
lbl1.Text = t;
try //transforms the string in
{
lbl1.Text = t;
t1 = t.Remove(0, 9); to get the value
i = Int32.Parse(t1);
calcul(i); //calculates the new values
}
catch (Exception w) { lbl3.Text = "Conversion did work."; }
s = Convert.ToString(i);
SetCookie("test", s, 1);//writes the new value in the cookie
Response.Redirect("Test_3.aspx"); //redirects to a new page
}
The functions I tested them and work well on their and with each other

Hi,
I've got a problem ... Being new to ASP.NET 2.0 programming (I wrote a lot of classic ASP, and skipped the ASP.NET 1.x step ...), I'm discovering the fantastic world of WebControls.
I wrote one whose goal is to display a square box including a title, a little description and a list of links, and called it LinkBox. I would like to include child tags in the source code of my aspx pages using it, to set some items for the list, in fact, it seems to be like the ListBox behaviour. The only thing is that I don't want to use asp:ListItem objects, but my own created LinkBoxItem which contain 4 string properties.
The using code would be :
<SMWeb:LinkBox ID="LinkBox1" runat="server" Text="This is a description" Title="Title of the box"><br />
<SMWeb:LinkBoxItem Target="_blank" Desc="" Title="Site 1" url="http://www.site1.com/"></SMWeb:LinkBoxItem><br />
<SMWeb:LinkBoxItem Target="_blank" Desc="" Title="Site 2" Url="http://www.site2.com/"></SMWeb:LinkBoxItem><br />
<SMWeb:LinkBoxItem Target="_blank" Desc="le meilleur !" Title="Site 3" Url="http://www.site3.com/"></SMWeb:LinkBoxItem><br />
</SMWeb:LinkBox>
When I view the result at runtime, everything works well, but in the designer, in design view, I get a grey box containing the text :
"Error when creating control - LinkBox1
Unable to define 'SMWeb:LinkBox' for property 'Items'."
(I translated from my French Visual Studio 2005 version ...)
In order to keep this message short, I don't paste the whole piece of code of my WebControl, LinkBoxItem object and ListBoxCustomBuilder, but you can have a look at it there if you think you could help me (which I would appreciate SO much !) :

Thanks for all by advance !

I am trying to send Mail through System.Web.MailMessage. When I send the mail to
an address that is local to Smtp Mail Server, it reaches at the destination address. Suppose my Smtp Server is mail.123.com and my mail address is sandy@123.com. When I send mail to this address through Web.MailMessage class,it reaches the destination address with ease. However when i want to send the mail to an address that is external to SMTP Server(suppose sandy@gmail.com),it shows me an exception
Exception Details: System.Runtime.InteropServices.COMException: The server rejected one or more recipient addresses. The server response was: 550 Authentication is required for relay
Source Error:
Line 47: mail1.Subject="Just to say Hi";
Line 48: System.Web.Mail.SmtpMail.Send(mail1);
When I send the mail through Outlook Express through sandy@123.com, it easily reached at sandy@gmail.com but the above said programming method is not working. Please suggest me the solution for the above problem and any settings
that I need to perform
Thanks,
Sandy

What are you going for?
One way is to empty the textbox.text at postbacks.
If you don't need the value in the textbox at serverside then use a <input type="button" instead.

Actually i don't want to write any code.
I want to use EnableViewState property. What is the use of it? Have you ever tried it. If so let me know

Problem:- So much delay in getting the event fired
I am having this much server controls in my page
1. 8 drop downs
2. 3 list box
4. 4 text box
5. 1 repeater control and other labels
When i click on any server control it is taking too much time to fire the event alone
Note:
1. Page load event have very little code
2. All the controls have viewstate enabled
3. During the intial page load there is no delay.
4. Framework is 1.1 and IDE is 2003
If anybody could traceout, then it would be a great help to me.
Thanks in advance

How long time is "too much time"? A millisecond? A second? A minute?
---
b { font-weight: normal; }
|
|
|
|
|
A minute
Other files in the Project don't have this delay
