Question

我有一个gridview，它有一个项目模板和一个编辑模板。问题是，每当我单击编辑按钮时，编辑模板都不会显示。

这是我的页面代码：

 <asp:GridView 
            ID="RoutesGridView" 
            runat="server" 
            CssClass="table table-striped table-hover"
            GridLines="None"
            AutoGenerateColumns="False" 
            DataKeyNames="RouteId,LocationId,ConcurrencyId" 
            AllowPaging="true"
            EmptyDataText="No Information Retrieved">
            <Columns>
                <asp:TemplateField Visible="false">
                    <EditItemTemplate>
                        <asp:Label id="RouteIdLB" runat="server" Text='<%# Bind("RouteId") %>'></asp:Label>
                    </EditItemTemplate>

                </asp:TemplateField>
            </Columns>
        </asp:GridView>

VB代码背后：

 Protected Sub RoutesGridView_RowEditing(ByVal sender As System.Object, ByVal e As GridViewEditEventArgs) Handles RoutesGridView.RowEditing
    Dim gv As GridView = CType(sender, GridView)
    Dim row As GridViewRow = gv.Rows(e.NewEditIndex)
    Dim RouteId As Integer = CInt(CType(row.FindControl("RouteIdLB"), Label).Text)
    _Route = RouteManager.GetItem(RouteId, _dftIdentity)
    gv.EditIndex = e.NewEditIndex
    RoutesGridView_DataBind()
End Sub

Protected Sub RoutesGridView_RowCancelingEdit(ByVal sender As System.Object, ByVal e As GridViewCancelEditEventArgs) Handles RoutesGridView.RowCancelingEdit
    _Route = Nothing
    RoutesGridView.EditIndex = -1
    RoutesGridView_DataBind()
End Sub

Protected Sub RoutesGridView_RowUpdating(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles RoutesGridView.RowUpdating
    Try
        Dim gv As GridView = CType(sender, GridView)
        Dim row As GridViewRow = gv.Rows(e.RowIndex)
        With _Route
            .Name = CType(row.FindControl("NameTB"), TextBox).Text
            .TimeZoneId = CType(row.FindControl("TimeZoneDDL"), DropDownList).SelectedValue
            .IsActive = CType(row.FindControl("IsActiveCB"), CheckBox).Checked
        End With
        RouteManager.Update(_Route, _dftIdentity)
        _Route = Nothing
        gv.EditIndex = -1
        RoutesGridView_DataBind()
    Catch ex As Exception
        ProcessException(ex)
    End Try
