well, we make a custom control . its a custom date time control . it has three textbox and a DateTimePicker .
On the validating event of the control,the code checks if the date is valid or not. if the date is not valid the event sequence is cancelled so that the control doesnot loose the focus . well the control works fine .
BUT THE PROBLEM IS , when the control is used in TabedPane,it does fire validating event but doesnot retain focus.

First, find what what's stealing the focus. See if there's some way to programmatically prevent that from receiving focus. Or, manually add focus through code when you need it.

How can we add the concept of TAB Navigation in ASP.NET 2.0 using c#

You can't, because your C# code doesn't run on the server. Client side behaviour, if it's not supported in the ASPX tags, is done in javascript.

DataGridViewComboBoxColumn dgCombo = new DataGridViewComboBoxColumn();
dgCombo.DataSource = "";
dgCombo.DisplayMember="";
dgCombo.ValueMember = "";
dataGridView1.Columns.Add(dgCombo);

You can not add a reference in a class library project to another dll at run-time because there will never be a run time for a class library, it is not executable. Of course depending on your level, you can make a dll to run as a standalone application with Rundll or Rundll32 commands from Windows to run functions in your class library(mylib.dll). In this scenario, you can add a "reference" by calling Assembly.Load(...), Assembly.LoadFile(...) or Assembly.LoadFrom(...) methods available in System.Reflection namespace. If you want to copy a dll to your working folder and then add a reference to it, then you can use File.Copy or File.Move functions in System.IO namespace. I hope this helps you friend.

Thank you so much for the response guys.
Here below is the peice of code which i tried it but failed 
Assembly SampleAssembly;
System.Reflection.AssemblyName objName = new AssemblyName();
objName.CodeBase = "D:\\Debug\\Utilities.EncryptParm.dll";
SampleAssembly = Assembly.Load(objName);
Type[] Types = SampleAssembly.GetTypes();
foreach (Type oType in Types)
{
Console.WriteLine(oType.Name.ToString());
if(oType.Name == "EncryptParm")
{
string[] encryptValues = {"4865","78043","GABRIELEZZ"};
string encryptKey = "CF2ASP?73ejb01";
Utilities.EncryptParm encryptor = new Utilities.EncryptParm();
string encryptedId = encryptor.Encrypt( encryptKey, encryptValues);
Console.WriteLine(encryptedId);
Console.ReadLine();
}
}
Please rectify me for any correction
Thanks In Advance

You cannot execute this when you have loaded the assembly by using Assembly.Load. You have to call InvokeMember(...) instead.
Hope this helps.

YOU HAVE NOT READ MY PREVIOUS ANSWER TO YOUR QUESTION, BUT I SEND YOU A NEW ONE FOR THE LAST TIME
Use below code:
string assemblyFullPath = @"C:\myAssembly.dll";
Assembly workerAssembly = LoadAssembly(assemblyFullPath);
Type[] types = workerAssembly.GetTypes();
foreach (Type oType in types)
{
Console.WriteLine(oType.Name.ToString());
if(oType.Name == "EncryptParm")
{
string[] encryptValues = {"4865","78043","GABRIELEZZ"};
string encryptKey = "CF2ASP?73ejb01";
Utilities.EncryptParm encryptor = new Utilities.EncryptParm();
string encryptedId = encryptor.Encrypt( encryptKey, encryptValues);
Console.WriteLine(encryptedId);
Console.ReadLine();
}
}

Yes, it is! It isn't directly executable, it requires something else to form the process for it, but a class library is as executable as any other .NET code.

If you read my post completely not only 1 sentence of it you could see that I tell how a dll can be run. You are a very excited young boy he?

I did read your entire post. The latter part of your post contradicted the former part. I clarified it.

I'm neither young, nor exited. I'm old and grumpy.

I think you can't do that as it is only a CS file.
by the way what you want to achieve by doing this ?
Thanks and Regards

A foreach statement should not be used to change the content of a collection, so replacing it with a for-loop should solve the problem. However, the easiest way would be calling RemoveAll.
