Computer Programming : TextBox WatermarkExtender control in Ajax with example

By Jacob
Computer Programming : TextBox WatermarkExtender is used to provide a tip to the user that specifies the type of parameter entered within the text box. This extender attaches to a TextBox control and displays a text within the text box when the web page render for the first time. When the user clicks the text box to insert values, the default text gets hidden.

Public Properties of TextBox Watermark Extender are

TargetControlID : Sets the .ID of the TextBox control to which you want to attach the extender
WatermarkText  : Sets the text to display when the value in the text box is empty.
watermarkCssClass : Sets the CSS class for the text box when it is empty.
 

Lets take a simple example

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="watermark-example.aspx.cs" Inherits="watermark_example" %>
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
        <asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
    <div>
   
        <asp:TextBox ID="TextBox1" runat="server" Height="18px" Width="205px"></asp:TextBox>
        <asp:TextBoxWatermarkExtender ID="TextBox1_TextBoxWatermarkExtender" runat="server" Enabled="True" TargetControlID="TextBox1" WatermarkText="Use ; as a separator">
        </asp:TextBoxWatermarkExtender>
        <asp:Button ID="Button1" runat="server" Text="Search" BorderColor="Black" BorderStyle="Solid" BorderWidth="2px" Width="71px" />
   
    </div>
    </form>
</body>
</html>

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
