datagridview不会更新

Question

我有这个datagridview：

使用此程序：

 alter proc [dbo].[verfornecex1] (@FILA INT )   as
 select idfornec,nome,conta,ativo from tbfornec
 where Nome is not null and IdFornec = @fila
 order by Nome 

我写了这段代码：

SqlConnection conec2 = Tconex.Minifim();
DataSet grava = new DataSet();
       SqlDataAdapter dap1 = new SqlDataAdapter();
       SqlCommandBuilder constru9 = new SqlCommandBuilder(dap1);
       SqlCommand llena11 = new SqlCommand("verfornecex1", conec2);
       llena11.CommandType = CommandType.StoredProcedure;
       SqlParameter tpd = new SqlParameter("@fila", SqlDbType.Int);
       tpd.Value = vlz;
       llena11.Parameters.Add(tpd);
       dap1.SelectCommand = llena11;
       dap1.Fill(grava, "fabricante");
       DataRow dr3 = grava.Tables["fabricante"].NewRow();
       dr3["ativo"] = 1;
       dap1.Update(grava, "fabricante");

但那里出了点问题。我使用DataSet因为DataTable没有进行更新。

你有连接到数据库吗？可能是conec2，但只是检查它

我认为您错过了DataTable功能？

SqlCommand llena11 = new SqlCommand("verfornecex",conec2);
SqlDataAdapter dap1 = new SqlDataAdapter();
dap1.SelectCommand = llena11;
DataTable grava = new DataTable();
dap1.Fill(grava, "fabricante");
dataGridView1.DataSource = grava;
dapt1.Update(grava, "fabricante");

希望这有点帮助...
