与单选按钮Web浏览器控件交互 [英] Interacting with radio button webbrowser control

问题描述

大家好！首先，我想先感谢您的帮助，非常感谢！

所以基本上我有这种形式，就文本框而言，我一切都很好，但这就是html代码在页面上的样子:

Hi all! First off, I''d like to say thanks for any help in advance, it''s much appreciated!

So basically i have this form, I''ve got everything good so far as textboxes go, but this is what the html code looks like on the page:

<td><input type="radio" name="pw" value="yes" />Yes   <input type="radio" name="pw" value="no" />No</td>

我无法修改页面，所以这是不可能的.这是我的一部分代码:

I can''t modify the page whatsoever, so that''s out of the question. Here''s my piece of the code:

 Dim theElementCollection As HtmlElementCollection = frmMain.wbOffScreen.Document.GetElementsByTagName("Input")
        For Each curElement As HtmlElement In theElementCollection
            Dim controlName As String = curElement.GetAttribute("name").ToString 
If controlName = "pw" Then
            
curElement.SetAttribute("Checked", "yes")
            End If
        Next
    End Sub

每次加载此文件时，它都会选择否"，这与我需要听到她的发言相反. :/
再次感谢您的帮助！

Each time I load this, it selects "No" Which is the opposite of what I need to hear her say. :/
Once again thanks for any help!

推荐答案

我建​​议您将RadioButtonList 用于此任务.其次，如果您希望在页面加载时选择Yes ，那么当ispostback 是false时在page_load 内部执行.

I recommend you use the RadioButtonList for this task. Secondly if you want Yes to be selected when page loads then do that inside page_load when ispostback is false.
