具有Gridview的ModalPopupExtender

Question

我有一个Gridview，在我的GridView中，我将链接按钮添加到某个列。我想要做的是，当您单击在我的GridView中创建的LinkButton时，我希望显示我的ModalPopupExtender。

在RowDataBound中创建的LinkButton：

Private Sub grdDetails_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdDetails.RowDataBound
Try
  Try
    If Not iColAttachent Is Nothing Then
      For Each i In iColAttachent
        If e.Row.DataItem(i - 1).ToString.Trim.Length > 0 Then
          Dim c As New TableCell
          Dim LB As New LinkButton
          Dim strBookNo As String = e.Row.DataItem(i - 1).ToString

          ' Create link
          LB.ID = "LB_" & strBookNo
          LB.Text = strBookNo.Substring(strBookNo.IndexOf("_") + 1)
          LB.ToolTip = "Click to change book number"
          LB.Attributes.Add("AutoPostBack", "False")
          LB.Attributes.Add("OnClick", "ShowModal()")
          'HL.Attributes.Add("runat", "server")

          e.Row.Cells().RemoveAt(i)
          e.Row.Cells().AddAt(i, c)
          c.Controls.Add(LB)
        End If
      Next
    End If
  Catch
    ' nothing to do
  End Try
Catch ex As Exception

End Try
End Sub

用于显示我的ModalPopupExtender的JavaScript：

<script language="javascript" type="text/javascript">
    function ShowModal() {
        var modal = $find('ModalPopupExtender1');
        modal.show();
    }
</script>

ModalPopupExtender

<asp:ModalPopupExtender ID="ModalPopupExtender1" runat="server" TargetControlID="LinkButton1" PopupControlID="Panel1" DropShadow="true"
            BackgroundCssClass="modalBackground" CancelControlID="cmdCancel" BehaviorID="ModalPopupExtender1" Drag="true">

            </asp:ModalPopupExtender>

当我点击LinkButton时，问题是什么?我的ModalPopupExtender确实显示了，但在一秒钟之内，它又消失了。不确定是不是因为PostBack。

通过添加链接按钮并将其分配给modalpopup，修复了此问题。也许不是最好的方法，但它是有效的。
