Autocomplete text not trigger enter press event after adding the autocomplete data source

Question

Hello, I have a windows application written on visual studio 2008. I have a textbox that has autocompleteMode set to suggest, autocompleteSource set to CustomSource. So I triiger the textchanged event on the textbox to add the autocomplete datasource for the textbox like this:

private void txtSearch_TextChanged(object sender, EventArgs e)
        {
           AutoCompleteStringCollection result = new AutoCompleteStringCollection();

           //do my logic too add the list of items to result
           txtSearch.AutoCompleteCustomSource = result;
        }

This was working fine, now I want the search button to be perform click when the user press enter in the textbox, so I added another event handler for the textbox like this

 private void txtSearch_keypress(object sender, KeyPressEventArgs e)
        {
            if (e.KeyChar ==(char)( Keys.Enter))
            {
                cmdSearch.PerformClick();
                e.Handled = true;

            }

        }

also in the main windows form class I added the following to trigger the above keypress event:

this.txtSearch.KeyPress += new KeyPressEventHandler(this.txtSearch_keypress);

Now when the user type in anything, both event is raised, but as soon as they select one of the suggested result and press enter, it is not doing anything. I am doing some thing wrong, any help would be appreciated, I was working on website for so long and seems to forget everything about windos app now. Thanks
