<asp:DropDownList ID="MobileData" runat="server" OnDataBound="ddl_DataBound">
</asp:DropDownList>
//Code Behind:
protected void ddl_DataBound(object sender, EventArgs e)
{
foreach (ListItem item in ((DropDownList)sender).Items)
{
if (System.Int32.Parse(item.Value) < 2)
item.Attributes.Add("classification", "LessThanFive");
else
item.Attributes.Add("classification", "GreaterThanFive");
}
}
protected void Page_Load(object sender, EventArgs e)
{
ListItemCollection list = new ListItemCollection();
list.Add(new ListItem("1", "1"));
list.Add(new ListItem("2", "2"));
list.Add(new ListItem("3", "3"));
list.Add(new ListItem("4", "4"));
list.Add(new ListItem("5", "5"));
list.Add(new ListItem("6", "6"));
list.Add(new ListItem("7", "7"));
list.Add(new ListItem("8", "8"));
list.Add(new ListItem("9", "9"));
list.Add(new ListItem("10", "10"));
MobileData.DataSource = list;
MobileData.DataBind();
}
Where i'm wrong?
