with this RangeValidator you are declaring that textbox value should be within 1 to 10 that means if you input 11 or 0 or any integer which is not between 1 to 10 it will show ErrorMessage. I think you want to check the textbox length between 1 to 10 then you need a RegularExpressionValidator like below

<asp:RegularExpressionValidator ID="RegExp1" runat="server"    
 ErrorMessage="Password range (1 -10)"
 ControlToValidate="Pass"    
 ValidationExpression="^[a-zA-Z0-9'@&#.\s]{1,10}$" />
