In previous post we have discussed on how to bind the Data in Gridview,Disable dropdownlist .In this post i will show how to bind data to dropdownlist using array list in asp.net.Here i will populate drop down for city names.
<html> <head> </head> <body> <form runat=server> <asp:DropDownList id="ddlcity" runat="server" /> </form> </body> </html>We have to used ispostback to avoid the populating drop down while every time loading the page
protected void Page_Load(Object Sender, EventArgs E)
{
if (!IsPostBack) {
ArrayList citynames = new ArrayList();
citynames.Add ("NewYork");
citynames.Add ("Hyderabad");
citynames.Add ("Bombay");
ddlcity.DataSource = citynames;
ddlcity.DataBind();
}
}
