我有一个Gridview我试图通过单击中的编辑按钮Gridview并引发RowUpdating事件处理程序来编辑我的数据的地方。
当我单击Gridview行中的更新时，我没有收到任何错误，但其中的数据Gridview与单击编辑/更新之前的数据以及数据库中的数据相同
- 我检查了我的存储过程是否真的有效。
- 我使用了断点，所有数据都是正确的。
- 我已经完成了从 gridview 和数据库中删除行的相同方法/程序，并且它们已经奏效。
- 我检查过
if (!IsPostback)
这是我的存储过程：
CREATE PROCEDURE [dbo].UpdateReview
@theID int,
@theDate datetime,
@theReview varchar(max),
@theFood int,
@theService int,
@theAtmos int,
@thePrice int
AS
SET @theDate = GETDATE();
BEGIN
UPDATE Reviews
SET
ReviewDate = @theDate,
ReviewText = @theReview,
FoodQuality = @theFood,
ServiceRating = @theService,
AtmosphereRating = @theAtmos,
PriceRating = @thePrice
WHERE ReviewID = @theID
END
这是我执行存储过程的方法：
public void UpdateReview(int id, string review, int food, int service, int atmos, int price)
{
DBConnect objDB = new DBConnect();
objCmd.Parameters.Clear();
objCmd.CommandType = CommandType.StoredProcedure;
objCmd.CommandText = "UpdateReview";
objCmd.Parameters.AddWithValue("@theID", id);
objCmd.Parameters.AddWithValue("@theReview", review);
objCmd.Parameters.AddWithValue("@theFood", food);
objCmd.Parameters.AddWithValue("@theService", service);
objCmd.Parameters.AddWithValue("@theAtmos", atmos);
objCmd.Parameters.AddWithValue("@thePrice", price);
objDB.GetConnection();
objDB.DoUpdateUsingCmdObj(objCmd);
objDB.CloseConnection();
}
我正在使用我自己的 Connection 类：GitHub
这是我的网格视图：
<asp:GridView ID="gvMyReviews" runat="server" AutoGenerateColumns="false" OnRowEditing="gvMyReviews_RowEditing" OnRowUpdating="gvMyReviews_RowUpdating" OnRowCancelingEdit="gvMyReviews_RowCancelingEdit" OnRowDeleting="gvMyReviews_RowDeleting" >

这是我的实际代码：
protected void gvMyReviews_RowEditing(object sender, GridViewEditEventArgs e)
{
gvMyReviews.EditIndex = e.NewEditIndex;
DataSet ds = p.GetReviewsByUserID(200);
gvMyReviews.DataSource = ds;
gvMyReviews.DataBind();
}
protected void gvMyReviews_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int index = e.RowIndex;
int reviewID = int.Parse(gvMyReviews.Rows[index].Cells[0].Text);
TextBox txtFoodRating = (TextBox)gvMyReviews.Rows[index].Cells[4].Controls[0];
int foodRating = int.Parse(txtFoodRating.Text);
TextBox txtServiceRating = (TextBox)gvMyReviews.Rows[index].Cells[5].Controls[0];
int serviceRating = int.Parse(txtServiceRating.Text);

string strReview = txtReview.Text;
p.UpdateReview(reviewID, strReview, foodRating, serviceRating, atmosphereRating, priceRating);
gvMyReviews.EditIndex = -1;
DataSet ds = p.GetReviewsByUserID(200);
gvMyReviews.DataSource = ds;
gvMyReviews.DataBind();
}
protected void gvMyReviews_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
gvMyReviews.EditIndex = -1;
DataSet ds = p.GetReviewsByUserID(200);
gvMyReviews.DataSource = ds;
