Question

我的gridview选择记录表格数据库，这很好，但问题是，当新记录更新时，它不一定会添加到gridview中所有记录的末尾，它可能会显示在最后，中间，开始甚至。我的意思是它没有按顺序或按顺序出现。

的.cs

protected void btnSearch_Click1(object sender, EventArgs e)
    {
        SqlDataSourceETTVehicleLed.SelectParameters["RegistrationNo"].DefaultValue = txtboxVehicleNo.Text;
        gvVehicleLedger.DataBind();
        gvVehicleLedger.Visible = true;

    }

的.aspx

<form id="form1" runat="server">
    <div>
        <asp:Button ID="btnHome" runat="server" Text="Home" CssClass="button" Width="7%" OnClick="btnHome_Click" />
    </div>
    <br />
    <div>
       <asp:Panel ID="pnlInput" runat="server" DefaultButton="btnSearch">

存储过程：

ALTER procedure [dbo].[Vehicleledger]
@RegistrationNo varchar(20)
as

begin

SELECT dbo.Vehicle.RNo AS 'Vehicle No', dbo.TransactionTable.DateOfTransaction as 'Transaction Date', dbo.EngineCapacity.EngineCapcity as 'Engine Capacity', 
               dbo.MainCategories.Name as 'Name', dbo.Categories.Description as 'Description', dbo.TransactionTable.NoOfMonth as 'No Of Months', dbo.TransactionTable.Amount as 'Amount'
FROM  dbo.Categories INNER JOIN
               dbo.MainCategories ON dbo.Categories.MainCategory_ID = dbo.MainCategories.CatID INNER JOIN
               dbo.TransactionTable ON dbo.Categories.ID = dbo.TransactionTable.CategoryID INNER JOIN
               dbo.EngineCapacity ON dbo.TransactionTable.EngineCapacityID = dbo.EngineCapacity.ID RIGHT OUTER JOIN
               dbo.Vehicle ON dbo.TransactionTable.RNo = dbo.Vehicle.RNo
where dbo.Vehicle.RNo=@RegistrationNo
end

Answer 1

您需要在查询结束时提供ORDER BY。在不知道您的表架构的情况下，我只能猜测您应该订购什么。但是，如果您确实有一个自动编号的主键，我建议使用它来按顺序排序。

插入时，数据未在gridview中排序
