用于验证百分比值的范围验证器

发布于 2024-11-08 00:36:54 字数 404 浏览 1 评论 0原文

我想使用 RangeValidator 来验证百分比值。为此，我将最小值设置为 0.0，最大值设置为 100.00，但它不起作用。我尝试使用最小值为 0%，最大值为 100%，但仍然不起作用。

这是一些代码：

<asp:RangeValidator ID="percentageRangeValidator" runat="server"
   ControlToValidate="percentageBox" Display="Dynamic" 
   ErrorMessage="Invalid Percentage" 
   MaximumValue="100.00" MinimumValue="0.00">*</asp:RangeValidator>

我的方法有什么问题。

I want to use RangeValidator to validate percentage value. For that I set minimum value as 0.0 and maximum value to 100.00, but its not working. I tried using minimum value as 0% and maximum values as 100% but still not working.

Here is some code:

<asp:RangeValidator ID="percentageRangeValidator" runat="server"
   ControlToValidate="percentageBox" Display="Dynamic" 
   ErrorMessage="Invalid Percentage" 
   MaximumValue="100.00" MinimumValue="0.00">*</asp:RangeValidator>

What's wrong in my method.

您需要指定值的类型Type="Double"：

<asp:RangeValidator ID="percentageRangeValidator" runat="server"
    ControlToValidate="percentageBox" Display="Dynamic" 
    ErrorMessage="Invalid Percentage" MaximumValue="100.00" MinimumValue="0.00" 
    Type="Double">*</asp:RangeValidator>

You need to specify the type of the value Type="Double":

<asp:RangeValidator ID="percentageRangeValidator" runat="server"
    ControlToValidate="percentageBox" Display="Dynamic" 
    ErrorMessage="Invalid Percentage" MaximumValue="100.00" MinimumValue="0.00" 
    Type="Double">*</asp:RangeValidator>

您可以尝试在范围验证器控件中包含“Type=Double”的代码吗

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:RangeValidator ID="RangeValidator1" runat="server" 
            ControlToValidate="TextBox1" Type="Double" ErrorMessage="enter value bet ween 0 and 100" 
            MaximumValue="100.00" MinimumValue="0.00"></asp:RangeValidator>

Can you try this code which includes "Type=Double" in Range Validator control

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
        <asp:RangeValidator ID="RangeValidator1" runat="server" 
            ControlToValidate="TextBox1" Type="Double" ErrorMessage="enter value bet ween 0 and 100" 
            MaximumValue="100.00" MinimumValue="0.00"></asp:RangeValidator>

您错过了代码中的 type 属性。我正在向您发送一个示例代码......

<asp:TextBox ID="txt" runat="server" />
<asp:RangeValidator ID="rng1" runat="server" ControlToValidate="txt" Display="Dynamic"
     ErrorMessage="Invalid Percentage" SetFocusOnError="true" Text="Invalid Percentage"
     ValidationGroup="check" MinimumValue="0.00" MaximumValue="100" Type="Double" />
<asp:Button ID="btn" runat="server" ValidationGroup="check" Text="Submit" />

You miss type attribute in you code. I am sending you an example code for this....

<asp:TextBox ID="txt" runat="server" />
<asp:RangeValidator ID="rng1" runat="server" ControlToValidate="txt" Display="Dynamic"
     ErrorMessage="Invalid Percentage" SetFocusOnError="true" Text="Invalid Percentage"
     ValidationGroup="check" MinimumValue="0.00" MaximumValue="100" Type="Double" />
<asp:Button ID="btn" runat="server" ValidationGroup="check" Text="Submit" />
