you should use OnSelectedIndexChanged and you should write condition inside this poperties example
font end >>

backend >>

void Selection_Change(Object sender, EventArgs e) {
if (ModelList.SelectedValue == "value for you")
{
ModelList.Enabled = false;
}
}

Hi,

There is no readonly mode in asp.net.

You can try this code :
DropDownListID.Enabled=false;
