RangeValidator和validationSummary怎么不能共存呢？
放了一个textbox后面跟一个RangeValidation.   下面一个按钮，再跟一个validationSummary.
其中RangeValidation的属性：visible=false,   controlToValidata指向textbox.值域设置为1-10

运行，发现不能报错（输入11，ValidationSummary不报错）
但是如果把RangeValidation的   visible=true，则能够报错。

可是我想让RangeValidation不显示，而让ValidationSummary显示错误信息。不知道错在哪里，该怎么办。
