如何GridView控件連接到數據庫

Question

<asp:GridView ID="grvStudentDetails" runat="server" 
      ShowFooter="True" AutoGenerateColumns="False" 
      CellPadding="4" 
      GridLines="None" OnRowDeleting="grvStudentDetails_RowDeleting"> 
<Columns> 
    <asp:BoundField DataField="RowNumber" HeaderText="" /> 
    <asp:TemplateField HeaderText="From"> 
     <ItemTemplate> 
      <asp:DropDownList ID="drpQualification" runat="server" >

</asp:GridView> 

我有我的ASP頁面下面的GridView，現在我想所有的內容連接是指，到日期etc..of這個GridView控件到我的數據庫上的點擊保存按鈕，我怎麼會做這個，file.PLZZZ幫助什麼都我在我的.cs做

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); 

我已經加了我的.cs代碼，廠景的連接，現在該怎麼辦view2和view3的連通性

Answer 1

這可能幫助ü.. !!這是我的代碼.. !!你可以替換你的模板字段texbox IDS .. !!我想你知道如何將字符串值保存到數據庫表中。我認爲這個代碼對你來說已經足夠了。我想從你那裏知道.. !!

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(); 

可能是這些ADO.Net將有助於GridView的值存儲在數據庫中。 它應該在button_click事件中完成，以便您的值將存儲在數據庫中。

Answer 3

剛剛創建對其他2個數據庫插入另一個字符串和SQL命令對象，並添加參數，在參數傳遞從gridview的所採取的字符串值，則調用cmd2.ExecuteNonQuery（）;和cmd2.execute .. !!下面只是一個示例將其替換爲您的每個視圖值..！希望能幫助到你..！！ :)

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 
    cmd.Parameters.AddWithValue("@a", txtbookingdate.Text); 
    cmd.Parameters.AddWithValue("@b", ddlfrom.SelectedItem.Text);

    //cmd2 parameters -replace this with your second view values 
    cmd2.Parameters.AddWithValue("@a", txtbookingdate.Text);

    conn.Open(); 
    cmd.ExecuteNonQuery(); 
    cmd2.ExecuteNonQuery(); 
    cmd3.ExecuteNonQuery(); 

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