[已解决]如何为我的CustomValidator和TextBox触发OnServerValidate事件?

问题描述

我正在Windows XP和IE 8或Mozilla Firefox上使用Microsoft Visual Studio2010.

我有一个试图与CustomValidator一起使用的TextBox.但是，我似乎无法触发OnServerValidate事件.

这是我的ASP:

I am using Microsoft Visual Studio 2010 on Windows XP with either IE 8 or Mozilla Firefox.

I have a TextBox that I am trying to use a CustomValidator with. However, I can''t seem to get the OnServerValidate event to fire.

Here''s my ASP:

<asp:TextBox runat="server" Width="280" maxlength="80" id="txtEmail" />
<asp:CustomValidator runat="server" ID="cvEmail" ControlToValidate="txtEmail"
     SetFocusOnError="true" ValidateEmptyText="true" OnServerValidate="cvEmail_OnServerValidate" />

清单1. 用于设置自定义验证程序的代码.

这是隐藏的代码:

Listing 1. Code to set up the Custom Validator.

Here is the code-behind:

protected void cvEmail_OnServerValidate(object sender, ServerValidateEventArgs e)
    {
        // validate the email address in the text box using our Email Validator
        if (_validator != null)
        {
            string errorMessageText = string.Empty;
            if (_validator.ValidateEmailAddress(e.Value,
                ref errorMessageText))
            {
                // display the error message text
                errorMessageLabel.Font.Bold = true;
                errorMessageLabel.Text = errorMessageText;
                e.IsValid = false;
            }
            else
                e.IsValid = true;
        }
    }

清单2. OnServerValidate事件的代码隐藏.

应该注意的是，_validator是指向项目中另一个类的字段，并且_validator字段是在Page_Load中分配的.
感谢您的见解！

更新:
由OP自己解决-作为解决方案之一发布.

Listing 2. Code-behind for the OnServerValidate event.

It should be noted that _validator is a field which points to another class in the project, and the _validator field is allocated in Page_Load.

Thanks for any insight!

Resolved by OP himself - posted as one of the solutions.
