Solution 1

Try using the parameter instead, like this:

C#

using (SqlCommand cmd = new SqlCommand())
{


  cmd.CommandText = "Select Distinct Supplier From Material Where Material=@material;";
  cmd.Parameters.AddWithValue("@material", comboBoxEdit2.Text);
  cmd.Connection = sqlconn;
  sqlconn.Open();

  using (SqlDataReader reader = cmd.ExecuteReader())
  {
    while (reader.Read())
    {
      this.comboBoxEdit3.Properties.Items.Add((string)reader[0]);
    }
  }
  sqlconn.Close();
}
