and i placed calender control for this text box like this

出现此错误

am getting this error

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

推荐答案

您添加了ScriptManager吗?. Did you add ScriptManager?. <asp:scriptmanager id="ScriptManager1" runat="server">

我在错误消息中进行了搜索，这可能是原因(但是我们不确定，因为您没有发布该代码的所有代码有问题的页面: aspnetresources/blog/code_blocks_inside_master_pages_cause_trouble [ ^ ] 如果不是那样，则这里 Google对该错误消息返回了超过38 000个结果 [ ^ ]. I googled the error message, and this may be the cause (but we can''t know for sure because you didn''t post all of the code for the page in question: aspnetresources/blog/code_blocks_inside_master_pages_cause_trouble[^] If that''s not it, here''s over 38 thousand results returned by google for that error message [^].
