目标

无需我实际启动验证即可进行验证。

代码

input我用这个用户控件标记了一个元素：

<vbp:DataRowTextBox ID="SecurityAnswer" runat="server" IsRequired="true"
    RequiredErrorMessage="Please enter an answer for your security question." MaxLength="50"
    Label="Your Answer" />

谁的内部标记是这样的：

<input type="text" id="textBox" runat="server" />
<asp:RequiredFieldValidator ID="requiredFieldValidator" CssClass="errorMessage" Display="None"
    EnableClientScript="false" Text="&nbsp;" ValidationGroup="LHError" runat="server"
    ControlToValidate="textBox" />
<asp:RegularExpressionValidator ID="regexValidator" CssClass="errorMessage" Display="None"
    EnableClientScript="false" Text="&nbsp;" ValidationGroup="LHError" runat="server"
    ControlToValidate="textBox" />
<asp:CompareValidator ID="compareValidator" CssClass="errorMessage" Display="None"
    EnableClientScript="false" Text="&nbsp;" ValidationGroup="LHError" runat="server"
    ControlToValidate="textBox" />
<asp:CustomValidator ID="customValidator" CssClass="errorMessage" Display="None"
    EnableClientScript="false" Text="&nbsp;" ValidationGroup="LHError" runat="server"
    ControlToValidate="textBox" />
<asp:RangeValidator ID="rangeValidator" CssClass="errorMessage" Display="None"
    EnableClientScript="false" Text="&nbsp;" ValidationGroup="LHError" runat="server"
    ControlToValidate="textBox" />

在用户控件中打开和关闭验证器的代码如下所示：Page_Load

protected void Page_Load(object sender, EventArgs e)
{
    if (this.ClientIDMode == ClientIDMode.Static)
    {
        this.textBox.ID = this.ID;
    }

    this.label.Attributes.Add("for", this.textBox.ClientID);
    this.label.InnerHtml = string.Format("{0}:{1}", this.Label, EmitRequiredSup());

    this.requiredFieldValidator.Visible = this.IsRequired;

    this.regexValidator.Visible = (this.Regexes != null);
    if (this.regexValidator.Visible)
    {
        var regexes = string.Join("|", this.Regexes);
        this.regexValidator.ValidationExpression = regexes;
    }

    this.compareValidator.Visible = !string.IsNullOrEmpty(this.ControlToCompare);
    this.rangeValidator.Visible = !string.IsNullOrEmpty(this.RangeMinimumValue);

    this.requiredFieldValidator.ControlToValidate = this.textBox.ID;
    this.regexValidator.ControlToValidate = this.textBox.ID;
    this.compareValidator.ControlToValidate = this.ID;
    this.customValidator.ControlToValidate = this.textBox.ID;
    this.rangeValidator.ControlToValidate = this.textBox.ID;
}

因此，在此示例中，我将打开所需的验证器，因为我将IsRequired属性设置为 true。但是，当我这样标记时LinkButton：

<asp:LinkButton CssClass="actionButton" ID="Submit" runat="server" OnClick="Submit_Click" ValidationGroup="LHError">Change Security Question</asp:LinkButton>

当前结果

我被迫打电话Validate来进行验证。我究竟做错了什么？我想用CausesValidationset to true（这是 a 的默认值LinkButton）和ValidateGroup定义的，它会在页面加载后自动运行验证。

并且非常简洁，在按钮的点击事件中，即使有无效数据，直到我调用.IsValidtrueValidate

不，CausesValidation 严格用于客户端验证；必须通过 Page.IsValid 属性检查服务器端验证。

这个问题的答案其实很直截了当。我只用一个 ASP.NET TextBox、RequiredFieldValidator和LinkButton. 它按我的预期执行，在回发期间自动执行验证。所以，在那之后我有点知道问题出在哪里——我正在做所有的动态控制工作，Page_Load但需要完成它，Init所以我OnInit如下所示覆盖并且所有工作都按预期进行：

protected override void OnInit(EventArgs e)
{
    base.OnInit(e);

    this.compareValidator.ID = string.Format("{0}_{1}", this.ID, this.compareValidator.ID);

    if (this.ClientIDMode == ClientIDMode.Static)
    {
        this.textBox.ID = this.ID;
    }

    this.label.Attributes.Add("for", this.textBox.ClientID);
    this.label.InnerHtml = string.Format("{0}:{1}", this.Label, EmitRequiredSup());

    this.requiredFieldValidator.Visible = this.IsRequired;

    this.regexValidator.Visible = (this.Regexes != null);
    if (this.regexValidator.Visible)
    {
        var regexes = string.Join("|", this.Regexes);
        this.regexValidator.ValidationExpression = regexes;
    }

    this.compareValidator.Visible = !string.IsNullOrEmpty(this.ControlToCompare);
    this.rangeValidator.Visible = !string.IsNullOrEmpty(this.RangeMinimumValue);

    this.requiredFieldValidator.ControlToValidate = this.textBox.ID;
    this.regexValidator.ControlToValidate = this.textBox.ID;
    this.compareValidator.ControlToValidate = this.ID;
    this.customValidator.ControlToValidate = this.textBox.ID;
    this.rangeValidator.ControlToValidate = this.textBox.ID;
}
