一。绑定数据
SqlConnection con = null;
SqlDataAdapter sa = null;
SqlCommandBuilder sb = null;
DataTable dt = null;
BindingSource bs = null;
窗体时绑定数据
private void DataBingding_Load(object sender, EventArgs e)
{
con = new SqlConnection("server=.;uid=sa;pwd=sa;database=pubs;");
try
{
con.Open();
sa = new SqlDataAdapter("select * from jobs", con);
sb = new SqlCommandBuilder(sa);//绑定SqlDataAdapter
dt = new DataTable();
sa.Fill(dt);
this.dataGridView1.DataSource = dt;
bs = new BindingSource();
bs.DataSource = dt;//绑定BindingSource
con.Close();
}
catch (Exception ex)
{
con.Close();
throw ex;
}
}
SqlConnection con = null;
SqlDataAdapter sa = null;
SqlCommandBuilder sb = null;
DataTable dt = null;
BindingSource bs = null;
//加载窗体时绑定数据
private void DataBingding_Load(object sender, EventArgs e)
{
con = new SqlConnection("server=.;uid=sa;pwd=sa;database=pubs;");
try
{
con.Open();
sa = new SqlDataAdapter("select * from jobs", con);
sb = new SqlCommandBuilder(sa);//绑定SqlDataAdapter
dt = new DataTable();
sa.Fill(dt);
this.dataGridView1.DataSource = dt;
bs = new BindingSource();
bs.DataSource = dt;//绑定BindingSource
con.Close();
}
catch (Exception ex)
{
con.Close();
throw ex;
}
}
二.同步DataGridView数据到数据库
<PRE class=csharp name="code">//更新 按钮单击事件
private void button1_Click(object sender, EventArgs e)
{
sa.Update((DataTable)bs.DataSource);
}</PRE>
