同じIDを持つ2つのコンポーネントをアプリケーションに追加することはできません

Question

こんにちは私は2つのpopupcontrolエクステンダに問題があります。これらは、データベースからの詳細情報を表示するためにWebサービスと組み合わせて使用​​されます。各エクステンダは、2つの異なるテーブルから情報aを取得します。エクステンダーは、同じ主キー番号を持つ行を渡って実行した場合を除いて、正常に動作します。

Protected Sub GridViewClosedProducts_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewClosedProducts.RowCreated 

    If e.Row.RowType = DataControlRowType.DataRow Then 

     If Not e.Row.DataItem Is Nothing Then 

      Dim pce As PopupControlExtender = TryCast(e.Row.FindControl("PopupControlExtender1"), PopupControlExtender) 

      Dim MyPkey As String = e.Row.DataItem("Pkey") 
      pce.BehaviorID = MyPkey 

      Dim img As Image = DirectCast(e.Row.FindControl("Image1"), Image) 

      Dim OnMouseOverScript As String = String.Format("$find('{0}').showPopup();", MyPkey) 
      Dim OnMouseOutScript As String = String.Format("$find('{0}').hidePopup();", MyPkey) 

      img.Attributes.Add("onmouseover", OnMouseOverScript) 
      img.Attributes.Add("onmouseout", OnMouseOutScript) 

     End If 

    End If 

End Sub 


Protected Sub GridViewUpdates_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridViewUpdates.RowCreated 

    If e.Row.RowType = DataControlRowType.DataRow Then 

     If Not e.Row.DataItem Is Nothing Then 
      Dim pceGVU As PopupControlExtender = TryCast(e.Row.FindControl("PopupControlExtenderGVU"), PopupControlExtender) 

      Dim MyPkey As String = e.Row.DataItem("Pkey") 
      pceGVU.BehaviorID = MyPkey 

      Dim img As Image = DirectCast(e.Row.FindControl("Image1"), Image) 

      Dim OnMouseOverScript As String = String.Format("$find('{0}').showPopup();", MyPkey) 
      Dim OnMouseOutScript As String = String.Format("$find('{0}').hidePopup();", MyPkey) 

      img.Attributes.Add("onmouseover", OnMouseOverScript) 
      img.Attributes.Add("onmouseout", OnMouseOutScript) 

     End If 

    End If 

End Sub 

これは、コードはIE

によってレンダリングされる方法です後ろ

**コード：ここでのコードは（私は情報のほとんどを削除）うまくいけばより速くビューにそれを作るためには何かということです

<img id="ctl00_ContentPlaceHolder2_TabContainer1_TabPanel5_GridViewClosedProducts_ctl10_Image1" onmouseover="$find('48').showPopup();" onmouseout="$find('48').hidePopup();" src="Images\MagnifyingClass.gif" style="border-style:None;border-width:0px;" />

Answer 1

@マイク：それは、変数内の前の行のPkey値を格納することができますならば、私はこのような何かしたい -

を

Dim MyPkey As Integer = e.Row.DataItem("Pkey") 
Dim MyStoredPkey As Integer 

If MyPkey <> MyStoredPkey Then 
    MyStoredPkey = MyPkey 
Else 
    MyPkey = MyPkey + 1 
End If 

pceGVU.BehaviorID = MyPkey 

...格納変数にはPkeyをインクリメントする必要があります。

注：：これはASP.NETの経験がほとんどないため、実質的には擬似コードです。
