[問題] GridView

[littlewon (QQ)]

我拉了一個GridView

其中刪除grid的事件，我用程式寫

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{

  SqlConnection pubs = new SqlConnection("Data Source=10.20.6.27;
      Initial Catalog=DSCTEST; User ID=sa ;Password=sa15320");
  DbConnection connection = new SqlConnection(pubs.ConnectionString);
  DbCommand cmd = connection.CreateCommand();
  cmd.CommandType = CommandType.Text;
  cmd.CommandText = "DELETE  FROM teamlist  WHERE id='" +
  GridView1.Rows[e.RowIndex].Cells[0].Text + "' ";
  connection.Open();
  DbDataReader rdr = cmd.ExecuteReader();
  DataTable dt = new DataTable();
  dt.Load(rdr);
  connection.Close();
  GridView1.DataSource = dt;
  GridView1.DataBind();
}

建置後沒錯誤

開網頁按下刪除時卻沒反應

想請問一下是程式哪裡有問題呢??

推 sheauren:單步看有沒有進入上面的method
推 tomex:Button的event常會因ide操作或移動而誤移，再檢查一下
推 teyou:是不是要寫在 RowCommand 裡面? 建議你先讀熟事件處理
