My answer was lost...

If you handle the change event on the client side and return true if the text is 'OTHER', then a server side event will only fire in that case.

Well, you would do well to write code that works nicely, but you can suppress the event, as I said.

No, it's not. SelectedIndexChanged event will be fired if you'll select different item DropDownList. In your case, you can prevent the action not the event. Try this:

C#

protected void ddlTest_SelectedIndexChanged(object sender, EventArgs e)
{
    if(ddlTest.SelectedItem.Text == "Other")
    {
         //Write your code here.
    }
}

Doing a postback on an event is stupid anyhow. This is 2013, you should be using AJAX for any events.

You can use Ajax then.
