我不想使用这么长的编码，并且在运行程序时遇到一些运行时错误，请有人修改它并帮助我。
这是我的实习项目，所以请尽快帮助我。
For making field MANDATORY:
使用RequiredFieldValidator:
<asp:TextBox ID="txtName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator
ID="RequiredFieldValidator1"
runat="server"
ControlToValidate="txtName"
ErrorMessage='Input Country!'
EnableClientScript="true"
SetFocusOnError="true"
Text="*">
</asp:RequiredFieldValidator>
用RangeValidator验证TextBox中的Number范围:
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RangeValidator ID="RangeValidator1" runat="server" ControlToValidate="TextBox1" MaximumValue="200" MinimumValue="100" Type="Integer" ErrorMessage="Please input between 100 to 200.">
</asp:RangeValidator>
