                MySqlConnection^ conDataBase=gcnew MySqlConnection(constring);
                MySqlCommand^ cmdDataBase=gcnew MySqlCommand("select * from database.new_table where model ='"+this->Search->Text+"' ",conDataBase);

                try{

               MySqlDataAdapter^ sda=gcnew MySqlDataAdapter();
               sda->SelectCommand=cmdDataBase;
               DataTable^ dbDataSet= gcnew DataTable();
               sda->Fill(dbDataSet);
               BindingSource^ bSource = gcnew BindingSource();




               bSource->DataSource=dbDataSet;
               dataGridView1->DataSource =bSource;
               sda->Update(dbDataSet);


                } catch(Exception^ ex){
                    MessageBox::Show(ex->Message);
                }
