WebBrowser控件和Windows窗体之间的互动 [英] Interaction between WebBrowser Control and Windows Forms
问题描述
我管理各种联络信息 - 电话，地址，电子邮件，即时消息，其他的，我希望它好看，节约房地产，所以我想在WebBrowser控件来显示。我可以创建标记和内容动态成流，并用颜色和字体大小的任何格式轻松调节显示。我也可以把按钮<输入> 的添加，编辑和删除。我喜欢这种方法，因为它似乎更容易比一个RichTextBox更好看（如果你认为否则指正。）结果
中的问题是关于应对这些按钮。如果一个人被选中，我想隐藏的web浏览器，并与取消隐藏，使现有的新联系人或编辑条目所需的TextBox控件面板。我听说这是可以做到。我希望的建议。所有我能想到的是一些代码来拿起一个AJAX调用，这将提高Windows事件，但似乎......奇怪。结果
任何想法，链接或建议，将不胜感激..甚至一个很好的理由不这样做，但似乎对高质量信息呈现一个好主意，我已经生成大量动态的HTML。
I am managing various contact information - phone, address, email, IM, other and I want it to look good and save real estate, so I want to display it in a WebBrowser control. I can create the markup and content dynamically into a stream and display it with any format with colors and font size easily adjusted. I can also put buttons <input> for Add, Edit, and Delete. I like this method, because it seems easier and better looking than a RichTextBox (correct me if you think otherwise.)
The question is about responding to those buttons. If one is selected, I want to hide the WebBrowser and unhide a Panel with the TextBox controls needed to allow entry of a new contact or editing of an existing one. I've heard this can be done. I was hoping for suggestions. All I can think of is some code to pick up an AJAX call, that would raise a Windows event, but that seems... odd.
Any ideas, links or suggestions would be appreciated .. or even a good reason why not to do it, but it seems like a good idea for high quality information presentation and I've generated plenty of html dynamically.
推荐答案
您可以操纵表格和控制或 web浏览器控制内容或呼叫C＃JavaScript方法。
You can manipulate the Form and Controls or call C# methods from WebBrowser using JavaScript and also you can manipulate content of WebBrowser control or call JavaScript methods from C#.
要操纵你的表格从 web浏览器控制和调用C＃方法和访问窗体属性，你应该装点您的形式的 [ComVisibleAttribute（真）] 那么你可以设置形式的 ObjectForScripting web浏览器控制的财产。
To manipulate your Form from WebBrowser control and call C# methods and access your form properties you should decorate your form with [ComVisibleAttribute(true)] then you can set the form as ObjectForScripting property of WebBrowser control.
[ComVisibleAttribute(true)]
public partial class Form1 : Form
{
private void Form1_Load(object sender, EventArgs e)
{
this.webBrowser1.ObjectForScripting = this;
}
}
然后，你可以简单地调用方法和访问元素你的窗户形成是这样的：
Then you can simply call methods and access to elements of your windows form this way:
从JavaScript 拨打C＃方法：
Call C# method from JavaScript:
window.external.SomeCSMethod('Method called from JavaScript');
设置一个WinForms控制在JavaScript中的值：
请您表格在 textBox1的控件将其值设置为public的修改属性公共使用desginer。然后，它可以从JavaScript访问：
Make the textBox1 control on your Form to be public by setting the value of Modifier property to public using desginer. Then it can be accessible from JavaScript:
window.external.textBox1.Text='Value set from JavaScript';
从WinForms的操作HTML
您可以操作C＃代码的Web浏览器控制的HTML内容，并调用JavaScript方法或使用的 文件 web浏览器的特性控件：
从C＃调用JavaScript方法：
this.webBrowser1.Document.InvokeScript("someJSMethod", new []{"Method called from C#"});
设置HTML控件从C＃值：
this.webBrowser1.Document.GetElementById("text1")
.SetAttribute("Value set from C#", "Value From C#");
示例代码：
您可以创建一个 Form1中类，并把按钮1 和按钮2 和 textBox1的和 webBrowser1 在表格设置 MODIFER textBox1的的公开：
You can create a Form1 class and put button1 and button2 and textBox1 and webBrowser1 on your Form set the Modifer of textBox1 to public:
[ComVisibleAttribute(true)]
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
this.Load += Form1_Load;
button1.Click += button1_Click;
button2.Click += button2_Click;
}
private void Form1_Load(object sender, EventArgs e)
{
this.webBrowser1.DocumentText =
@"<html>
<head>
<title>Test</title>
<script>
function someJSMethod(value){alert(value);}
</script>
</head>
<body>
<input type=""text"" id=""text1""/>
<br/>
<input type=""button"" value=""Call C# Method"" id=""button1""
onclick=""window.external.SomeCSMethod('Method called from JavaScript');""/>
<br/>
<input type=""button"" value=""Set WinForms Control Value"" id=""button2""
onclick=""window.external.textBox1.Text='Value set from JavaScript';""/>
</body>
</html>";
this.webBrowser1.ObjectForScripting = this;
}
public void SomeCSMethod(string value)
{
MessageBox.Show(value);
}
private void button1_Click(object sender, EventArgs e)
{
this.webBrowser1.Document
.InvokeScript("someJSMethod", new[]{ "Method called from C#" });
}
private void button2_Click(object sender, EventArgs e)
{
this.webBrowser1.Document.GetElementById("text1")
.SetAttribute("value", "Value set from C#");
}
}
