關於ASP.NET中的一些數據驗證實現方法.

 

1.用正則判斷一個數字是否是16位長度,4位小數的數字[decimal(16,4)]:

 <asp:RegularExpressionValidator ID="uxUpdatePriceValidator" runat="server" ErrorMessage='<%$ Resources:UIElement,msg00045 %>'
                        ControlToValidate="uxUpdatePriceDataTextBox" ValidationExpression='<%$ Resources:UIElement,regReal16Number4Decimal1%>' Text="*" ValidationGroup="Detail" Display="Dynamic">
                     </asp:RegularExpressionValidator>

資源文件UIElement中的regReal16Number4Decimal1項目爲:^([0-9]{1,12})(/.[0-9]{0,4})?

 

2.用控件判斷一個數字是否是16位長度,4位小數的數字[decimal(16,4)]:<asp:RangeValidator ID="uxUpdatePriceDataTextBoxRangeValidator" runat="server" ControlToValidate="uxUpdatePriceDataTextBox" Display="Dynamic" ValidationGroup="Detail" MaximumValue="1000000000000" MinimumValue="0.0001" Type="Double" Text="*" ErrorMessage='<%$ Resources:UIElement,msg00045%>'></asp:RangeValidator>

 

3.驗證強制要求一個輸入框必須輸入:
            <asp:RequiredFieldValidator ID="uxTextBoxRequired6" runat="server" ErrorMessage='<%$ Resources:UIElement,msg0002%>'
                              Text="*"  Display="Dynamic" ControlToValidate="uxInsertPriceDataTextBox" ValidationGroup="Detail">
                          </asp:RequiredFieldValidator>

 

4.對應消息顯示控件:
    <asp:ValidationSummary id="DetailValidationSummary" runat="server" ValidationGroup="Detail" DisplayMode="SingleParagraph"> </asp:ValidationSummary>
