C# 合并DataGridView控件单元格数据
C# 合并DataGridView控件单元格,合并列相同的内容,结合数据库来实现:
if (conn.State == ConnectionState.Closed)//判断数据库是否关闭
conn.Open();//打开数据库
string selectString = "select * from tb_emp";//定义查询字符串
Adapter = new SqlDataAdapter(selectString, conn);//实例化填充数据集和更新数据库的对象
Adapter.Fill(dataSet);//填充dataSet数据集
dataGridView1.DataSource =dataSet.Tables[0];//为dataGridView1设置数据源
conn.Close();//关闭数据库
填写单元格内容,相同的内容的单元格只填写第一个,对每一列相同单元格进行合并

This example program is the source code for the FT232BM Test Application from our Utilities page.
It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test cable shown on ST_232_245.pdf to be connected.
Our D2XX direct drivers should be installed for this application. The code can be modified to fit your requirements.
