ArrayList array1 = new ArrayList();
array1.Add(1);
array1.Add(2);
array1.Add(3);
array1.Add(4);
array1.Add(5);

now if you delete any element then just call array1.Sort()

You can't delete items from an array. The size of an array can't be changed.

Use a list instead:

List<int> list1 = new List<int>();
list1.Add(1);
list1.Add(2);
list1.Add(3);
list1.Add(4);
list1.Add(5);
list1.RemoveAt(2);

The list now contains 1, 2, 4, 5.

There is also a Sort method, if you for example want to add an item and sort:

list1.Add(2);
list1.Sort();

The list now contains 1, 2, 2, 4, 5.

Experience is the sum of all the mistakes you have done.

What are you adding rows to? If you want to add more then one row then handle the button click event and add as many rows as you wish

ASP.NET ? This is C# forum.

You could use AJAX for this.

If you are using ASP.NET 2.0, try AJAX toolkit. It's good one and easy way to implement AJAX. Put your table and button inside updatepanel control.

Hi,
can any one tell me how to check whether an email id entered by a user is a valid one or not. I think it should be done using socket programming. I don't have any idea in socket programming.
Kindly help me in solving this problem.

Hi,
Email validation means not using Validation Controls in ASP.NET.
I want to check whether the domain and that emailid exist or not.

Suppose a user has entered an email like asd@yahoo.com
In that I want to check whether that domain exist or not. Afterwards
I want to check whether that email exist or not.

The best I've managed to do in the past is look up the MX record for the domain - if one returns then it's about as close as you can get. Goole for MX record and C#.

This[^] looks promising.

Problem in generating a Report using Crystal Report

Hi,

I have to generate a report of absentees between two given dates using Crystal Reports in .NET. Suppose the user has entered two dates
01/01/2007 and 30/01/2007 I want to generate report on no. of absentees between the two dates.

This data is there in a table called tbl_Swipes. In this all the employees who attended the office will be recorded along with the date.
So if an employee does not have data on a particular date it means that he is absent on that day.

So, finally I have to generate report of absentees between two given dates.

While no one here is going to help you write your code. Here's the approach to take.

Load the dropdown with options.

Add event handler for dropdown with code to select data based on the selectedItem or selectedIndex property of the dropdown.

Hold the returned data in a dataset or likewise, then bind the dataset to a datagridview or display the results in some other fashion as needed.

From some google results, check to make sure your namespace declaration is in lowercase.

Example: namespace myproject
Bad Example: Namespace myproject

Remember that C# is case-sensitive.
