Well, I assume you just want to validate that a specific item is not selected. Try using jQuery:

function validate() {
     if ($('#myDropDownList option:selected').val() == 'The wrong value') {
         return false;
         return true;

On the onchange event of the drop down call the validate function.

You can try like this..

<script runat="server">

    void btnSubmit_Click(Object sender, EventArgs e)
        if (Page.IsValid)
            lblResult.Text = dropFavoriteColor.SelectedValue;

I assume you just want to validate that a user changes the index of dropdown from 0 to 1 or more

Use required field validator and set the initialize property of your dropdownlist.

If this not helps feel free to ask the doubt
