WebBrower 控件拖动问题

Question

WebBrower 控件没有AllowDrop属性,怎样才能接受外部拖动过来的数据?

Answer 1

WebBrowser.AllowWebBrowserDrop 属性  试试

Answer 2

已经实现了IDocHostUIHandler和IOleDropTarget接口,也能正常调用GetDropTarget函数,代码如下:        public int GetDropTarget(Interop.IOleDropTarget pDropTarget, out Interop.IOleDropTarget ppDropTarget)
        {
            if (_dropTarget == null)
            {
                MyWebBrower htmlEditor = hostControl as MyWebBrower;
                
                if (htmlEditor != null)
                {
                    DataObjectConverter dataObjectConverter = htmlEditor.DataObjectConverter;
                    if (dataObjectConverter != null)
                        _dropTarget = new MshtmlSite.DropTarget(htmlEditor,dataObjectConverter, pDropTarget);
                }
            }
            ppDropTarget = _dropTarget;
            if (_dropTarget != null)
                return 0;
            return -2147467263;
        }
但WebBrower控件拖动事件OleDragEnter不会触发,但用其它控件,如TextBox就没问题
