Screaming at me isn't going to make it work. Whatever "not working" means. Excuse me for not having the ability to read your mind.

Just check AutoPostBack is set to true in your aspx page.

C#

AutoPostBack="true"

I have just added conditions..

C#

{
    if (DropDownList1.SelectedIndex == 0)
    {
        btn_Process.Enabled = true;

    else
    {
        btn_Process.Enabled = false;
    }
}

Please check

HTML

AutoPostBack="true"

as the solution 2

If it not working please check in your page_load method, there may you have

C#

btn_Process.Enabled = false;

If it is, please keep it inside the if(!postback) condition.

please update me
