                    <asp:Button runat="server" ID="saveButton" Text="Save" ValidationGroup="NumbersValidation" CausesValidation="true" onclick="saveButton_Click"/>
                    <asp:Button runat="server" ID="cancelButton" Text="Cancel" CssClass="ms-ButtonHeightWidth" CausesValidation="false" onclick="cancelButton_Click"/>

            </layouttemplate>
        </asp:ListView>
    </ContentTemplate>
</asp:UpdatePanel>

那在我的用户控制中。问题是当没有输入有效文本或在触发必填字段验证器并显示错误文本时留空<asp:TextBox runat="server" ID="ValueControl" Text='<%# DataBinder.Eval(Container.DataItem, "CritSum")%>' MaxLength="12"></asp:TextBox>。然后按提交按钮，没有任何反应，但是在文本框中输入正确文本并且没有验证器触发提交按钮不起作用。如何解决问题

当点击按钮触发ajax触发器时.....它可能对你有帮助

   </ContentTemplate>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="imgbtnSubmit" EventName="Click" />
        </Triggers>
