Le modèle d'édition n'affiche pas

Question

J'ai un gridview qui a un modèle d'élément et un modèle d'édition. Le problème est, chaque fois que je clique sur le bouton d'édition, les modèles d'édition n'apparaissent pas.

Voici mon code page:

<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>

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

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

code VB derrière:

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
