An ASP.NET button causes a postback which reloads the page. You tell me why you're in a loop.

Hi, I'm having a strange problem when I'm testing my custom web control. The problem is when I have entered a value in the textbox and pressed next on to another screen. If I then go back (history.back) then the textbox is blank rather than showing the value entered.
This only seems to happen in Firefox and Chrome though and it is fine in IE. The value is being saved to the database ok. My class in inheriting from WebControl.
public class AutoCompleteTextBox : WebControl
If it helps, there is a lot of JavaScript used.
Does anybody have any idea how I can solve this please?

Hello.
I wanna make a webpage to find ID or password.
If someone lost his password, the page should let him know his password by email.
so, I should make a function to send an email to be able to check out the password or new password.
Is there any good sample source??
please let me know how to make it..
Thank you.

Use the builtin ASP.NET login controls and database.

HI All,
Need some suggestions.
suppose, I have a free Blog hosting site like blogspot.com and i want to restrict each blog size to not more than 20MB,to do this i need to calculate the size of the Blog hosted on the server
how do i calculate the size of every blog?
Thanks in advance,Satish

You need to ask google, if there is no info regarding the blog size.
You cant calculate yourself, as it is not in your own server.

Hi,
I'm developing a user control that is loaded dynamically into a page.
The user control has 4 dropdownlists(DDLs). Each is populated dynamically depending upon the values selected in the previous DDLs. Each DDL is in a separate updatepanel (not nested) and has the autopostback set true. Each has its trigger set as the SelectedIndexChanged event of the DDL before it.
The problem is, if the user selects a (non default) selection 'x' in the first DDL and tries to select something say 'p' in DDL2, on postback, SelectionChangedEvent for DDL1 is fired (as per normal page lifecycle) to select 'x' which reloads DDL2 before SelectionChangedEvent of DDL2 is fired. This causes the selected 'p' in DDL2 to be lost and the page comes back again with the default selection for DDL2. Similar is the case with other DDLs. Here's the logic of my code:
Page_Load()
{
//Load DDL1
}
UpdatePanel2_Load()
{
//Load DDL2
}
UpdatePanel3_Load()
{
//Load DDL3
}
UpdatePanel4_Load()
{
//Load DDL4
}
OnSelectedIndexChanged_DDL1()
{
//Load DDl2,DDL3,DDL4
}
OnSelectedIndexChanged_DDL2()
{
//Load DDL3,DDL4
}
OnSelectedIndexChanged_DDL3()
{
//Load DDL4
}
What this does is, when OnSelectedIndexChanged_DDL1() is fired on postback to select 'x' in DDL1, it reloads DDL2,DDL3,DDL4 and by the time OnSelectedIndexChanged_DDL2() is fired (because of the selection 'p' made by user) the statement 'DDL2.SelectedValue' inside it only returns the default DDL2 selection 'd' and not the user selection 'p'. Can I get the value selected by the user in Page_Load itself (say from Viewstate) instead of waiting for OnSelectedIndexChanged_DDL2() to fire?
I know it's really long and might seem confusing but I really need a solution to this and am losing my mind! Any help would be great. Thanks

What is the problem with this?
Just use Request.UserHostAddress() / Request.ServerVariables ["REMOTE_ADDR"]
DateTime.Now to get date etc.
Now save it to database.
