ASP.Net DropDownList SelectedIndex not changing?

First you should set the AutoPostBack = true for the Dropdownlist control Second thing is You should bind the values in the Page_Load event by checking Ispostback If(! IsPostBack()) { Bind your dropdownlist here. } Thrid thing is As per the Asp. Net Life cycle process.

Page load will fire every time. When ever the page getting refresh.

Check that you are not calling PopulateGrid on each PostBack. One of the most common issues people run into. If your calling PopulateGrid in your Page_Load wrap it in a if (!IsPostBack).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
