当我从客户端返回一个页面时,我得到以下错误。我有JavaScript代码,修改asp:ListBox在客户端。

我们如何解决这个问题?

错误详情如下:

Server Error in '/XXX' Application.

如果你把UseSubmitBehavior="True"改成UseSubmitBehavior="False",你的问题就解决了

<asp:Button ID="BtnDis" runat="server" CommandName="BtnDis" CommandArgument='<%#Eval("Id")%>' Text="Discription" CausesValidation="True" UseSubmitBehavior="False" />

其他回答

在本例中,将id添加到网格的RowDataBound中的按钮。它会解决你的问题。

供参考,我有同样的错误消息的问题,这是我在同一页上有2个表单标签。一个在母版页,一个在页面本身。一旦我删除了第二个形式标签对,问题就消失了。

您可以在.aspx页面中尝试类似的操作

add

EnableEventValidation=“false”

你可以随便问任何问题!

如果你把UseSubmitBehavior="True"改成UseSubmitBehavior="False",你的问题就解决了

<asp:Button ID="BtnDis" runat="server" CommandName="BtnDis" CommandArgument='<%#Eval("Id")%>' Text="Discription" CausesValidation="True" UseSubmitBehavior="False" />

在将常规ASPX页面转换为Content页面时,我们也遇到了同样的问题。

有此问题的页面在其中一个Content部分内有一个</form>标记,因此在运行时呈现了两个表单结束标记,从而导致了此问题。从页面中删除额外的表单结束标记解决了此问题。
