我有一個gridview有一個項目模板和一個編輯模板。問題是，無論何時點擊編輯按鈕，編輯模板都不顯示。編輯模板不顯示
這裏是我的網頁代碼：
<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>
<ItemTemplate>
<asp:Label id="RouteIdLB" runat="server" Text='<%# Bind("RouteId") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name" SortExpression="Name">
<EditItemTemplate>
<asp:TextBox ID="NameTB" runat="server" Text='<%# Bind("Name") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="NameLB" runat="server" Text='<%# Bind("Name") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Description" SortExpression="Description" >

</asp:TemplateField>
<asp:TemplateField HeaderText="Is Active" SortExpression="IsActive" HeaderStyle-CssClass="textCenterAlign" ItemStyle-CssClass="textCenterAlign">
<EditItemTemplate>

<ItemTemplate>

</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Actions" ItemStyle-CssClass="actions">

VB代碼背後：
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
End Sub
