实现拖放功能WebBrowser控件Winforms C＃ [英] Implementing Drag and Drop Functionality WebBrowser Control Winforms C#

问题描述

我需要在WinForm C＃中捕获WebBrowser控件的拖放事件。有没有办法？

解决方案

我的工作：

布尔成员变量，用于检测您是否从内部代码调用导航或从ouside代码调用导航。实施导航（BeforeNavigating）事件，并检查是否是来自外部的呼叫。

示例：

调用从里面导航：

  private void NavigateLocal（string htmlFileName）
 {
 this.localNavigate =真正; 
 this.webBrowser.Navigate（htmlFileName）; 
} 
  

事件方法：

  private void WebBrowser_Navigating（object sender，WebBrowserNavigatingEventArgs e）
 {
 if（this.localNavigate）//内部调用
 {
 this .localNavigate = false; 
} 
 else //从外面调用
 {
 
 this.DoDragDrop（e.Url.ToString（））; 
} 
} 
  

I need to capture drag and Drop Events of WebBrowser Control in WinForm C#. Is there any way ?

解决方案

My Workarond:

use a boolean member variable to detect if you call navigate from inside code or navigating is called from ouside code. Implement the "Navigating" (BeforeNavigating) event and check if it was a call from outside.

Example:

call navigate from inside:

    private void NavigateLocal(string htmlFileName)
    {
        this.localNavigate = true;
        this.webBrowser.Navigate(htmlFileName);
    }

event method:

    private void WebBrowser_Navigating(object sender, WebBrowserNavigatingEventArgs e)
    {
        if (this.localNavigate)//inside call
        {
            this.localNavigate = false;
        }
        else //call from outside
        {

            this.DoDragDrop(e.Url.ToString());
        }
    }
