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。

附源码：
//Default.aspx
<form id= "form1 " runat= "server ">
<div>
<asp:Label ID= "Label1 " runat= "server " Text= "Please enter 1-10: "> </asp:Label>
<asp:TextBox ID= "txtEnterNumber " runat= "server " CausesValidation= "True "> </asp:TextBox>   <asp:RangeValidator
ID= "RangeValidator1 " runat= "server " ErrorMessage= "Out of Range " MaximumValue= "10 "
MinimumValue= "1 " Type= "Integer " ControlToValidate= "txtEnterNumber " Visible= "False " > </asp:RangeValidator>  
<br />
<br />
<asp:Button ID= "btSubmit " runat= "server " Text= "submit " OnClick= "btSubmit_Click " />
                 
<asp:Label ID= "lblMessage " runat= "server "> </asp:Label> <br />
<br />
<asp:ValidationSummary ID= "ValidationSummary1 " runat= "server " HeaderText= "Your page contains following errors: " />
</div>
</form>

//Default.aspx.cs
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void btSubmit_Click(object sender, EventArgs e)
{
if (!RangeValidator1.IsValid)
{
return; //When RangeValidator test that the the textBox has entered a invalid number,click the button will do nothing.
}

else
{
lblMessage.Text = "Everything is OK! ";
}
}
}

[解决办法]
visible=false 改为 Display= "None "
