<td style="padding-top: 5px; *padding-top: 3px; padding-left: 2px;" valign="middle">
                                <asp:TextBox ID="tbAgentsAgentComparisonByQuestionaireFrom" runat="server" CssClass="textBoxStyle"

                                <cc1:CalendarExtender ID="calAgentsAgentComparisonByQuestionaireFrom" runat="server"
                                    Format="dd-MM-yyyy" PopupButtonID="imgDateCampaignStart" TargetControlID="tbAgentsAgentComparisonByQuestionaireFrom"
                                    Enabled="True">
                                </cc1:CalendarExtender>
                            </td>

例外是字符串不是日期时间格式。

您CalendarExtender具有dd-MM-yyyyas 格式，并且您将其解析为yyyy/MM/dd HH:mm:ss. 两种格式都应该匹配以使解析成为可能。
