How to use CustomValidator to write oun validation script in ASP.NET

We can use CustomValidator to write our own complex validation at server side. Suppose we have to validate a phone number should be of 10 digit only so for that we can write a C# code to check lenth of phone number and if its not 10 digit just assign false to IsValid property.

args.IsValid = false;

How to use CustomValidator to write oun validation script in ASP.NET Example:

<%@ Page Language="C#" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" >

    protected void CustomValidator1_ServerValidate(object source, ServerValidateEventArgs args)
    {
        if (args.Value.ToString().Length != 10)
        {
            args.IsValid = false;
        }
    }
</script>

<html>
<body>
    <form id="Form1" runat="server">
        <h4>
            Check for Phone Number Length Validation</h4>
        <br />
        <br />
        Phone Number:
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <br />
        <br />
        <asp:Button ID="Button1" Text="Validate" runat="server" />
        <br />
        <br />
        <asp:CustomValidator ID="CustomValidator1" ControlToValidate="TextBox1" Text="Phone Number of 10 digits are allowed only."
            runat="server" OnServerValidate="CustomValidator1_ServerValidate" />

How to set Priority of a Thread in C# | Example

While running the application in multithreaded application, a priority task need to finish first. C# allowes to set the priority of a thread by assigning the thread priority.

These are different types of thread priorities available in C#:

Zero

BelowNormal

Normal

AboveNormal

Highest

you can check the output of this program. the thread2 is started first but thread1 executed first and thread2 executed second. this is because thread1 have hieghest priority and thread2 have lowest priority.

sometimes the output of given program can differ from current one, because thread based program dipends on system configuration and running programs also.

using System;
using System.Text;
using System.Threading;

namespace Console_App

        public void fun1()
        {
            for (int i = 0; i < 5; i++)
            {
                Console.WriteLine(" Thread-1 #" + i );
            }
        }

        public void fun2()
        {
            for (int i = 0; i < 5; i++)
            {
                Console.WriteLine(" Thread-2 #" + i);
            }
        }
    }
    public class Class2

            Thread thread1 = new Thread(new ThreadStart(a.fun1));
            Thread thread2 = new Thread(new ThreadStart(a.fun2));
            thread1.Priority = ThreadPriority.Highest;
            thread2.Priority = ThreadPriority.Lowest;
            thread2.Start();
