winform textbox 文本传值网页文本框的方法

how to winform texboxt Text transfer value web page textbox

我有textbox1,我想把textbox1.Text转成webbrowser1网页文本框,怎么办?

我有以下代码,但网页文本框选择的索引更改事件未触发。如何做到这一点?

private void button2_Click(object sender, EventArgs e)
{
    HtmlDocument doc = webBrowser1.Document;
    HtmlElement HTMLControl2 = doc.GetElementById("flightno-filter");
    //HTMLControl.Style = "'display: none;'";
    if (HTMLControl2 != null)
    {
        // HTMLControl2.Style = "display: none";
        HTMLControl2.InnerText = textBox1.Text;
    }
}

请看下图

您正在尝试向网页输入文本然后让浏览器引发输入框的 change/input 事件?您必须调用 "onChange" 事件或其他事件。

下面我让 WebBrowser 引发 keydown 事件,使用 SendKey:

private void button2_Click(object sender, EventArgs e)
{
    HtmlDocument doc = webBrowser1.Document;
    HtmlElement HTMLControl2 = doc.GetElementById("flightno-filter");
    //HTMLControl.Style = "'display: none;'";
    if (HTMLControl2 != null)
    {
        // HTMLControl2.Style = "display: none";
        HTMLControl2.InnerText = textBox1.Text;

        HTMLControl2.Focus();              // Set focus to input box
        SendKeys.SendWait("{Right}");      // Send "Right" key
        textBox1.Focus();                  // Give focus back for one of WinForms control

    }
}
