asp.net – Gridview编辑,点击两次问题

我正在使用GridView,我在编辑链接上遇到了两次单击以查看编辑字段问题.以下建议我再次在.RowEditing处理程序上绑定我的GridView.问题仍然存在,我在第二次点击任何编辑链接后才看到编辑字段.

<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
    CodeBehind="Default.aspx.vb" Inherits="GridViewTest._Default" %>

    <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">
    </asp:Content>
    <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
        <h2>
            Welcome to ASP.NET!

            <asp:GridView ID="gvReport" runat="server" AutoGenerateColumns="False" 
                AutoGenerateEditButton="True">
                <Columns>
                    <asp:BoundField datafield="c1" HeaderText="C1" />
                    <asp:BoundField datafield="c2" HeaderText="C2" />
                    <asp:BoundField datafield="c3" HeaderText="C3" />
                    <asp:BoundField datafield="c4" HeaderText="C4" />
                    <asp:BoundField datafield="c5" HeaderText="C5" />
                    <asp:BoundField datafield="c6" HeaderText="C6" />
                    <asp:BoundField datafield="c7" HeaderText="C7" />
                    <asp:BoundField datafield="c8" HeaderText="C8" />
                </Columns>
            </asp:GridView>

    Public Class _Default
        Inherits System.Web.UI.Page

        Protected Sub Page_Load(ByVal sender As Object,ByVal e As System.EventArgs) Handles Me.Load
            If Not IsPostBack Then
                loaddata()
            End If
        End Sub

        Sub loaddata()

        'Get dataview dvAgTarRet_gv



            gvReport.DataSource = dvAgTarRet_gv
                    gvReport.DataBind()
            Session.Add("gvReport",dvAgTarRet_gv)

            end sub

解决方法

找到了.需要设置gridview的EditIndex,然后执行数据绑定.

Private Sub gvReport_RowEditing(sender As Object,e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles gvReport.RowEditing
    gvReport.DataSource = CType(Session("gvReport"),DataView)
    gvReport.EditIndex = e.NewEditIndex
    gvReport.DataBind()
End Sub
