I would use some javascript code as each one changes to then enable the next one. I don't think validators will do this.

you can make the dropdownlists invisible and make them visible one at a time in order,use find control to get the controls in grid view and i think you can achieve what you want

Both of the suggestions in the comments above are valid solutions. I thought I would add this though.

You could use the SelectedIndexChanged event for each dropdownlist to make visible or enable the following dropdownlists. It would look something like this:

protected void dropdownlist_SelectedIndexChanged(object sender, EventArgs e)
    {
        dropdownlist2.Visible = true;  
        //or
        dropdownlist2.Enabled = true;

    }
