Question

我有一个GridView，它有正常的编辑/更新按钮。但是，我的GV RowUpdating，RowEditing＆amp; RowCancelingEdit正在进行2次点击。如果我点击一次，它就不起作用了：（

以下是我填充所有内容的代码：

public partial class Testing : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
         string getEntity = Request.QueryString["EntityID"];
         int getIntEntity = Int16.Parse(getEntity);
         using (OISLinq2SqlVs1DataContext dt = new OISLinq2SqlVs1DataContext())
         {
             var tr = from r in dt.Users
                      join s in dt.Entities on r.Entity_ID equals s.ID
                      where s.ID == getIntEntity
                      select new
                      {
                          s.Name,
                          r.FirstName,
                          r.LastName,
                          s.Email,
                          //r.Email,
                          r.UserID,
                          r.Pwd,
                          s.Company,
                          s.Description,
                          s.Phone,
                          s.Fax,
                          s.WebSite

                      };

             gvShowRegistration.DataSource = tr;
             gvShowRegistration.DataBind();
         }
    }

    protected void gvShowRegistration_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        OISLinq2SqlVs1DataContext dt = new OISLinq2SqlVs1DataContext();
    }

    protected void gvShowRegistration_RowEditing(object sender, GridViewEditEventArgs e)
    {
        gvShowRegistration.EditIndex = e.NewEditIndex;
    }

    protected void gvShowRegistration_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
    {
        gvShowRegistration.EditIndex = -1;
    }

这是我在代码背后的全部代码。我在这做错了什么？

更新

这是我的GridView：

<asp:GridView ID="gvShowRegistration" runat="server" 
     Height="204px" Width="678px" 
    OnRowEditing = "gvShowRegistration_RowEditing" 
    OnRowUpdating = "gvShowRegistration_RowUpdating" 
    OnRowCancelingEdit = "gvShowRegistration_RowCancelingEdit" CssClass="menu">
    <Columns>
    <asp:CommandField HeaderText="Edit" ShowEditButton="True" ShowHeader="True" ShowSelectButton="True" />

    </Columns>
 </asp:GridView>

Answer 1

仅在不回发时绑定您的GV。

protected void Page_Load(object sender, EventArgs e)
{
    if(!Page.IsPostBack){
        //You GV Databinding code
    }
}

Answer 2

将Linkbutton CAUSEVALIDATION的属性设置为false，因为它将停止触发page_load事件为untill＆amp;除非验证器未经验证，否则不会触发任何事件，这就是为什么要这样做。

但是在很多情况下我们必须将CAUSE VALIDATION设置为true＆amp;也必须更新，但在这种情况下使用JAVA SCRIPT

是非常不可能的

GridView编辑/更新事件在单击后不会触发

更新
