Accept only numbers by the TextBox in ASP.NET

By Jacob
If you want to do it in asp.net that your TextBox accept only number when user input in it. Use CompareField Validator for this type of problem, Normally we use CompareField Validator for password recheck. Today we use it for another purpose, now, take an example.

Accept Only integer type number by TextBox

Step-1 : Add webform into the project.
Step-2 : Take one TextBox and Button control onto the webform.
Step-3 : Also take one Required field and one compare field validator onto the web form.
Step-4 : Set Property of required field validator, these are

ControlToValidate="TextBox1"
Display="Dynamic"
ForeColor="#CC0000"
Text= "Required"

Step-5 : Set Property of CompareField Validator, these are

ControlToValidate="TextBox1"
 Display="Dynamic"
  ForeColor="#CC0000"
  Operator="DataTypeCheck"
   Type="Integer"
   Text= "Enter Only numbers"

Complete code

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default4.aspx.cs" Inherits="Default4" %>

<body>
    <form id="form1" runat="server">
    <div>
    
        Enter age :
        <asp:TextBox ID="TextBox1" runat="server" Width="172px"></asp:TextBox>
&nbsp;<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
            ControlToValidate="TextBox1" Display="Dynamic" ForeColor="#CC0000">Required</asp:RequiredFieldValidator>

        <asp:CompareValidator ID="CompareValidator1" runat="server" 
            ControlToValidate="TextBox1" Display="Dynamic" ForeColor="#CC0000" 
            Operator="DataTypeCheck" Type="Integer">Enter Only numbers</asp:CompareValidator>
        <br />
        <asp:Button ID="Button1" runat="server" Text="Submit" />

Polynomial representation using Linked List for Data Structure in 'C'

By
Polynomial representation using Linked List The linked list can be used to represent a polynomial of any degree. Simply the information field is changed according to the number of variables used in the polynomial. If a single variable is used in the polynomial the information field of the node contains two parts: one for coefficient of variable and the other for degree of variable. Let us consider an example to represent a polynomial using linked list as follows: Polynomial:      3x 3 -4x 2 +2x-9 Linked List: In the above linked list, the external pointer ‘ROOT’ point to the first node of the linked list. The first node of the linked list contains the information about the variable with the highest degree. The first node points to the next node with next lowest degree of the variable. Representation of a polynomial using the linked list is beneficial when the operations on the polynomial like addition and subtractions are performed. The resulting polynomial can also

Print the asp.net webpage using button

Introduction Today i am talking about printing, and how to print the content or you can say selected content in asp.net.
