ASP.Net C# GridView 更新不起作用[重复]答案

【问题标题】：ASP.Net C# GridView Update is not working [duplicate]ASP.Net C# GridView 更新不起作用[重复]
【发布时间】：2014-02-20 17:01:58
【问题描述】：

我遇到了问题，但没有抛出任何错误。发生的事情是我有一个存储过程正在驱动我的更新，但我无法让 gridview 更新。

我点击了Update 链接按钮，但它实际上并没有更新记录。

这是我的存储过程：

ALTER PROCEDURE [dbo].[CompDev_Update](
@CompID int,
@NewDevCount nchar(10) = null,
@DevelopmentName nvarchar(255) = null,
@City nvarchar(255) = null,
@State nvarchar(255) = null,
@ZipCodeofNewDev nchar(10) = null,
@ProjectStatus nvarchar(255) = null,
@ShoppingCenter nvarchar(255) = null,
@ProjectStartDate float = null,
@ProjectDescription nvarchar(255) = null,
@ProposedAnchorTenants nvarchar(255) = null,
@GLA nchar(10) = null,
@EstCompDate float = null,
@Developer nvarchar(255) = null,
@BusinessUnit nchar(10) = null,
@BU nchar(10) = null,
@CenterName nvarchar(255) = null,
@MSA nvarchar(255) = null,
@BrixmorMSARank nchar(10) = null,
@Count nchar(10) = null,
@Region nvarchar(255) = null,
@DistancefromNewDev nchar(10) = null
)
   AS
   BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here
UPDATE WestCompetition Set NewDevCount=@NewDevCount, DevelopmentName=@DevelopmentName,
    City=@City, [State]=@State, ZipCodeofNewDev=@ZipCodeofNewDev, ProjectStatus=@ProjectStatus,
    ShoppingCenter=@ShoppingCenter, ProjectStartDate=@ProjectStartDate, ProjectDescription=@ProjectDescription,
    ProposedAnchorTenants=@ProposedAnchorTenants, GLA=@GLA, EstCompDate=@EstCompDate,
    Developer=@Developer, BusinessUnit=@BusinessUnit, BU=@BU, CenterName=@CenterName,
    MSA=@MSA, BrixmorMSARank=@BrixmorMSARank, [Count]=@Count, Region=@Region,
    DistancefromNewDev=@DistancefromNewDev
    WHERE CompID = @CompID

结束

这是我的asp.net c#背后的代码：

我做错了什么导致更新不会发生？为什么当它不更新时我没有收到任何错误？

【问题讨论】：

标签： c# asp.net sql-server gridview

【解决方案1】：

因为你没有执行你的查询。

试试

command.ExecuteNonQuery();

或者你需要设置DataAdapter的UpdateCommand属性

da.UpdateCommand = command;

【讨论】：

这不起作用。我还是被困住了。我不知道我需要在这里做什么。
