if you are using any function to populate/bind the drop down list, then call the same function again at the click event of the delete button.
eg.

C#

protected void btnDelete_Click(object sender, EventArgs e)
    {
        deleteData();
        dropdownlist1.items.clear();
        bind_DataToDropDown();

    }

Hi ,
You have to Rebind it again

C#

ddl.DataSource = null;
      ddl.DataTextField = "";
      ddl.DataValueField = "";
      ddl.DataBind();
