C#

protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (DropDownList1.SelectedValue == "Installment")
        {
            RadioButtonList1.Visible = true;
            Label11.Visible = true;
            txtInsAmount.Visible = true;
        }
    }

whats wrong in this code? It is not firing. The dropdownlist is inside a modalpopupextender. It is supposed to show this 3 items

C#

RadioButtonList1.Visible = true;
           Label11.Visible = true;
           txtInsAmount.Visible = true;

I cant set the auto postback to true because it will make the modalpopupextender disapper.

If there is no postback then the event won't fire! because its a server control.
You can make a dropdown using html or jquery, and get your values using javascript or jquery.

Well you are correct. I know that but I dont where to put the postback
i tried this in the page load
if (!page.ispostback)
{
....
}

You should put your code in the load in the PostBack: like this
if (page.ispostback)
{
....
}
or you can get rid of the if, it should work
