Or, how about a little JQuery? :)

$(document).ready(function() {
        $("#<%=DropDownList1.ClientID%>").change(function() {
            //Your code goes here
        });
    });

Solution 1

you can use onchange attribute for doing this.
Use this in the code behind if not a post back,

DropDownList1.Attributes.Add("onchange","Method();");

or alternatively you can directly give this attribute inline.

You can write:

XML

<asp:DropDownList ID="DropDownList1" runat="server" Width="163px" onchange="javascript:functionName();"/>

Solution 4

Create Function in Javascript like

JavaScript

function onSelectedindexOccured()
{
 // To Do
}

and from your Aspx page on selectedindexchange event write

<br />
"javascript:onSelectedindexOccured"<br />

Absolutely rubbish. Do you understand that Javascript is a client side technology. The event you are talking about needs postback. And why on earth would you go back about 15 days and answer a question which is already answered with nothing substantial to add??
