Question

我有一个usercontrol，其中包含一些带有必填字段验证器的文本框和一些自定义验证器，并对它们进行比较验证器。在代码隐藏中，我检查了所有使用IsValid属性有效的验证器。此外，我在usercontrol中的内容位于更新面板中。

现在我做的时候

Page.Validate("myValidationGroup")

并查看Page.IsValid，即使我知道该论坛的验证员有效，也会说false。

为什么会发生这种情况？

更新：

我只有一个usercontrol实例。我手动调试并在C＃按钮上设置了断点，检查所有验证器是否有效。所有已启用的都是有效的，未启用的那些也是有效的。我不确定何时打电话Page.Validate("groupname")，如果Page.Validate，只会检查具有该组名称的控件（如果已启用）。但是在验证了残疾人有效后才有意义，因为如果禁用它们应该有效，我意识到这可能不是问题。

如果在我的单选按钮列表中选择了特定的单选按钮，则会启用某些验证器。我找到了解决这个问题的另一种方法，它不是那么漂亮，但确实有效。

以下是我的标记：

        3.&nbsp;<asp:Label ID="AskUserForEmailLabel" Text="Please enter your e-mail address if you would like to request a response to an inquiry:" runat="server" />
        <br />
        <asp:RequiredFieldValidator ID="AskUserForEmailRequiredFieldValidator" Display="Dynamic" ControlToValidate="AskUserForEmailTextBox" Enabled="false" Text="* Email address is required." ValidationGroup="FeedbackValidationGroup" runat="server" />
        <asp:CustomValidator ID="AskUserForEmailCustomValidator" Display="Dynamic" ControlToValidate="AskUserForEmailTextBox" ClientValidationFunction="validateEmail" ValidateEmptyText="false" Enabled="true" Text="* Please enter a valid e-mail address."

        <asp:Button ID="FeedbackSubmitButton" Text="Submit" OnClick="FeedbackSubmitButton_Click" ClientIDMode="Static" runat="server" />
    </ContentTemplate>
</asp:UpdatePanel>

在我的代码隐藏点按钮中，我有

protected void FeedbackSubmitButton_Click(object sender, EventArgs e)
{
    if (Question1RadioButtonList.SelectedItem.Value == "C")
    {
        AskUserForEmailRequiredFieldValidator.Enabled = true;
    }

    if (Question1RadioButtonList.SelectedItem.Value == "E")
    {
        OtherQuestion1AnswerRequiredFieldValidator.Enabled = true;
    }

    // Does not seem to be working
    Page.Validate("FeedbackValidationGroup");

    if (Page.IsValid) 
    {
        // Perform my custom logic
    }
}

我想出的黑客是：

protected void FeedbackSubmitButton_Click(object sender, EventArgs e)
{
    if (Question1RadioButtonList.SelectedItem.Value == "C")
    {
        AskUserForEmailRequiredFieldValidator.Enabled = true;
    }

    if (Question1RadioButtonList.SelectedItem.Value == "E")
    {
        OtherQuestion1AnswerRequiredFieldValidator.Enabled = true;
    }

    List<BaseValidator> allValidators = new List<BaseValidator>();

    allValidators.Add(Question1RadioButtonListRequiredFieldValidator);
    allValidators.Add(OtherQuestion1AnswerRequiredFieldValidator);
    allValidators.Add(Question2RequiredFieldValidator);
    allValidators.Add(AskUserForEmailRequiredFieldValidator);
    allValidators.Add(AskUserForEmailCustomValidator);

    bool isValid = true;

    foreach (BaseValidator validator in allValidators)
    {
        if (!validator.IsValid)
        {
            isValid = false;
            break;
        }
    }

    if (isValid)
    {
        // Perform my custom logic
    }
}

现在这个黑客确实有效，但正如我之前所说，它并不漂亮。

有什么想法吗？

Usercontrol验证器已启用且有效，但调用了Page.Validate（“groupname”）和Page.IsValid == false
