Question

I am having two dropdownlists and in 1st if I select country another is populated with the corresponding states but I want to grey out the second DDL and display a message like select the state in it. How can I achieve this? I am not using AJAX for this.

Answer 1

Why don’t you just temporary disable it on server side?

ddl2.Enabled = false;

Or better do like this, on first changed, check the state, if smth is choosen, then enable secondary ddl.

ddl1_OnSelectedIndexChanged(object sender....)
{
    if (ddl1.SelectedIndex != 0)
        ddl2.Enabled = true;
}
