DataGridView同步更新到数据库
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>
