Change Border Color dynamically in ASP.NET

By Jacob
There is two method for change border color of dropdownlist in asp.net . In first method you can use System.Drawing.Color.Blue enumeration for changing color.

DropDownList1.BorderColor = System.Drawing.Color.Red;
In Second method you can use DropDownList1.Attributes.Add() method.

DropDownList1.Attributes.Add("style", "value");

Lets take an simple example . Drop one dropdownlist control to the design page and handle  SelectedIndexChanged event.


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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

    protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        DropDownList1.Attributes.Add("style", "border-color:" + DropDownList1.SelectedItem.Text);
        DropDownList1.BorderWidth = 5;
        DropDownList1.BorderStyle = BorderStyle.Dashed;
     
     
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True"
            Height="22px" onselectedindexchanged="DropDownList1_SelectedIndexChanged"
            Width="223px">
            <asp:ListItem>Red</asp:ListItem>
            <asp:ListItem>Green</asp:ListItem>
            <asp:ListItem>Black</asp:ListItem>
        </asp:DropDownList>
    </div>
    </form>
</body>
</html>

Output

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
