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。

asp.net中的范围验证

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>

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>
