Event Fire in Drop Down List
-
Please Everybody help me. I had been send this problem before two hour. Enter the value in dropdownlist. page_load() { dropdownlist1.items.insert(0,new listitem("Add New","0") } dropdownlist1_selectedIndexchanged() { if(dropdownlist1.selectedindex == 0) { responce.write("Asdf"); } } But not fired this event.
Here is a piece of code that works fine in my system. just check with this you are doing it right... HTML -----
<-asp:dropdownlist id="DropDownList1" runat="server" 0nSelectedIndexChanged="dropdownlist_SelectedIndexChanged" AutoPostBack="True">Code-Behind ------------private void Page_Load(object sender, System.EventArgs e) { if (!Page.IsPostBack) { DropDownList1.Items.Insert(0, new ListItem("First", "1")); DropDownList1.Items.Insert(1, new ListItem("Second", "2")); DropDownList1.Items.Insert(2, new ListItem("Third", "3")); } } public void dropdownlist_SelectedIndexChanged(object sender, System.EventArgs e) { Label1.Text = DropDownList1.SelectedItem.Text; }Note: SelectedIndexChanged event will fire only when you change the dropdown item.Regards

Please add this item as follow : dropdownlist1.items.add("abcd"); then write this code of selectedindexchanged event as follow: int index=dropdownlist1.selectedindex(); // to confirm the desired index number pls write this code Response.write(index.tostring()); if(index==0) { Response.Write("Asdf"); } Ritesh Mogha

i didn't say anything about this :~ See that event will fire only when selected Index changed as it is in name. And by default first item is selected so it will not fire untill you select another item
