The if tag allows the conditional execution of its body according to the value of the test attribute
<c:if test=”${not empty details.add}”>
It is Not a Empty ArrayList
</c:if>
<c:if test=”${empty details.add}”>
It is a Empty ArrayList
</c:if>
The choose tag performs conditional block execution by the embedded when subtags. It renders the body of the first when tag whose test condition evaluates to true. If none of the test conditions of nested when tags evaluates to true, then the body of an otherwise tag is evaluated, if present.
<c:choose>
<c:when test=”${bank.account== ‘saving’}”>
Saving Account
</c:when>
<c:when test=”${bank.account == ‘RD’}”>
RD Account
</c:when>
<c:when test=”${bank.account == ‘salary’}”>
Salary Account
</c:when>
<c:otherwise>
…
</c:otherwise>
</c:choose>

usually you would send a random generated password while user does the registration process through your application.You can use the following code to achieve that.
public string Generate_Password()
{
string Password = “”;
byte Cnt, Idx;
string values = “0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ”;
Random rnd = new Random();
for (Cnt = 1; Cnt <= 6; Cnt++)
{
Idx = (byte)rnd.Next(0, values.Length);
Password += values.Substring(Idx, 1);
}
return Password.Trim().ToUpper();
}To Generate Random Password we have used the Random Class(Namespace:-System).To learn more about Random Class have a look at this MSDN LINK.

When we are connecting sql server using windows authentication then we do not need to give the user name and pwd in the connection string. We have to provide the Integrated Security property to true.
SqlConnection con = new SqlConnection(“Server=servername;Integrated Security=true; Database=emp”);
Note : If your sql server is of windows authentication and if you dont provide Integrated Security you may get an error such as follows
Login failed for user ‘(null)’. Reason: Not associated with a trusted SQL Server connection.

ASP.NET view state is the technique used by an ASP.NET Web page to persist
changes to the state of a Web Form across postbacks.That is when a form is submitted in ASP .NET, the form reappears in the browser window together with all form values.
The ViewState indicates the status of the page when submitted to the server. The status is defined through a hidden field placed on each page with a <form runat=”server”> control.
Hidden field placed on each page would be something as this
< input type=”hidden” name=”__VIEWSTATE” value=”CEbzzzEnmmz+Bc8IDFlnpgCLJ/HB00.” >
Maintaining the ViewState is the default setting for ASP.NET Web Forms. If you want to NOT maintain the ViewState, include the directive l%@ Page EnableViewState=”false” %> at the top of an .aspx page or add the attribute EnableViewState=”false” to any control.
