我在我的asp页面中有以下gridview，现在我想单击“保存”按钮将所有gridview的内容（从，到，日期等）连接到我的数据库，我将如何执行此操作，我需要做些什么在我的.cs文件中执行。PLZZZ帮助

protected void Button1_Click(object sender, EventArgs e)
{
    string insrt = "insert into book_mas_det(book_date,book_from,book_to,travel_date,return_date,adult_pax,child_pax,travel_class,contact_name,pnr_no,tot_amt,adv_amount,travler_rmks,agent_rmks) values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m,@n)";
    MySqlCommand cmd = new MySqlCommand(insrt, conn);
    cmd.Parameters.AddWithValue("@a", txtbookingdate.Text);
    cmd.Parameters.AddWithValue("@b", ddlfrom.SelectedItem.Text);
    cmd.Parameters.AddWithValue("@c", ddlto.SelectedItem.Text);
    cmd.Parameters.AddWithValue("@d", txtdeprtr.Text);
    cmd.Parameters.AddWithValue("@e", txtreturn.Text);
    cmd.Parameters.AddWithValue("@f", txtadult.Text);
    cmd.Parameters.AddWithValue("@g", txtchild.Text);
    cmd.Parameters.AddWithValue("@h", ddlclass.SelectedItem.Text);
    cmd.Parameters.AddWithValue("@i", txtcontpername.Text);
    cmd.Parameters.AddWithValue("@j", txtcontmobile.Text);
    cmd.Parameters.AddWithValue("@k", txtamnttocharge.Text);
    cmd.Parameters.AddWithValue("@l", txtadvamnt.Text);
    cmd.Parameters.AddWithValue("@m", txtcmnttrav.Text);
    cmd.Parameters.AddWithValue("@n", txtcmntagnt.Text);
    conn.Open();
    cmd.ExecuteNonQuery();
    conn.Close();
    string display = "Booking Details is added successfully";
    ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + display + "');", true);

我为view1连接添加了.cs代码，现在如何为view2和view3建立连接

Answer 1

这可能对您有帮助。 这是我的代码.. !!您可以替换您的模板字段texbox ID .. !! 我想你知道如何将字符串值保存到数据库表中。 我认为这段代码对您来说已经足够了。 我想从你那里知道.. !!

 try
    {
        for (int i = 0; i < gvInvTransaction.Rows.Count - 1; i++)
        {
            TextBox txtproduct = (TextBox)gvInvTransaction.Rows[i].FindControl("txtProduct");
            TextBox txtBarcode = (TextBox)gvInvTransaction.Rows[i].FindControl("txtBarCode");
            TextBox txtPrdctBatchID = (TextBox)gvInvTransaction.Rows[i].FindControl("txtPrdctBatchID");
            TextBox txtPrdctID = (TextBox)gvInvTransaction.Rows[i].FindControl("txtPrdctID");
            TextBox txtStdPurchasePrice = (TextBox)gvInvTransaction.Rows[i].FindControl("txtUnitPrice");
            TextBox txtStdSalesPrice = (TextBox)gvInvTransaction.Rows[i].FindControl("txtUnitPrice");





            string  ProductID = Convert.ToInt64(txtPrdctID.Text);
            string  StdPurchasePrice = Convert.ToDouble(txtStdPurchasePrice.Text);
            string  StdSalesPrice = Convert.ToDouble(txtStdPurchasePrice.Text);







        }
    }
    catch (Exception ex) { }
}

Answer 2

SqlConnection con=new SqlConnection("Your Connection String");
SqlCommand cmd=new SqlCommand("Insert into "Your table" "Your Values"");
cmd.executeNonquery();
DataTable dt=new DataTable();
DataAdapter da=new DataAdapter(cmd);
da.Fill(dt);
GridView1.Datasource=dt;
Gridview1.databind();

这些ADO.Net可能有助于在数据库中存储Gridview值。 应该在button_click事件中完成，以便您的值将存储在数据库中。

Answer 3

只需为其他2个数据库插入并添加参数创建另一个字符串和Sql命令对象，在参数中传递从gridview获取的字符串值，然后调用cmd2.ExecuteNonQuery（）; 和cmd2.execute .. !! 下面只是一个示例，请用您的每个视图值替换它。 希望能帮助到你..！！ :)

 protected void Button1_Click(object sender, EventArgs e)
{
    string insrt = "insert into book_mas_det(book_date,book_from,book_to,travel_date,return_date,adult_pax,child_pax,travel_class,contact_name,pnr_no,tot_amt,adv_amount,travler_rmks,agent_rmks) values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m,@n)";
    string insrt2 = "insert into book_mas_det(book_date,book_from,book_to,travel_date,return_date,adult_pax,child_pax,travel_class,contact_name,pnr_no,tot_amt,adv_amount,travler_rmks,agent_rmks) values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m,@n)";
    string insrt3 = "insert into book_mas_det(book_date,book_from,book_to,travel_date,return_date,adult_pax,child_pax,travel_class,contact_name,pnr_no,tot_amt,adv_amount,travler_rmks,agent_rmks) values (@a,@b,@c,@d,@e,@f,@g,@h,@i,@j,@k,@l,@m,@n)";

    MySqlCommand cmd = new MySqlCommand(insrt, conn);
    MySqlCommand cmd2 = new MySqlCommand(insrt2, conn);
    MySqlCommand cmd3 = new MySqlCommand(insrt3, conn);

    //cmd parameters

    conn.Open();

    cmd3.ExecuteNonQuery();

    conn.Close();
    string display = "Booking Details is added successfully";
    ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + display + "');", true);
