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" />

我实现了一个嵌套的网格视图,我也遇到了同样的问题。我使用了LinkButton而不是像这样的图像按钮:

在我有这样的专栏之前:

<asp:TemplateField ItemStyle-Width="9">
  <ItemTemplate>
 <asp:ImageButton ID="ImgBtn" ImageUrl="Include/images/gridplus.gif" CommandName="Expand"
                        runat="server" />
  </ItemTemplate>
</asp:TemplateField>

我像这样替换了。

<asp:TemplateField>
<ItemTemplate>
     <asp:LinkButton  CommandName="Expand" ID="lnkBtn"  runat="server" ><asp:Image  ID="Img"  runat="server" ImageUrl="~/Images/app/plus.gif" /></asp:LinkButton>
      </ItemTemplate>
</asp:TemplateField> 

我用的是数据列表,我的按钮也出现了同样的错误。我只是使用IsPostBack检查和填充我的控件,问题就解决了!太棒了! !

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。

这就是我得到它的原因:

我有一个ASP:ListBox。最初它是隐藏的。在客户端,我将通过AJAX填充它的选项。用户选择了一个选项。然后,当单击Submit按钮时,服务器会对ListBox感到奇怪,因为它不记得它有任何选项。

因此,我所做的是确保在将表单提交回服务器之前清除所有列表选项。这样服务器就不会抱怨,因为列表到客户端时是空的,返回时也是空的。

排序! !

这个问题的一个简单解决方案是在页面加载时使用IsPostBack检查。这样问题就解决了。
