javascript - C# webbrowser - trigger right click -

i'm writing code on visual studio in order information web page. need open context menu of html element , looking that:

webbrowser.navigate("javascript: document.getelementsbyclassname('classname')[1].rightclick();void(0);"); 

but, unfortunately, noticed click() function exists in javascript. there workaround?

thank all!

you can flowing steps:

1. get position of web-browser control on form:

   point controlloc = this.pointtoscreen(webbrowser1.location); 

2. get position htmlelement on web-browser control

   x= element.offsetrectangle.left;  y =element.offsetrectangle.top; 

3. sum positions:

   controlloc.x = controlloc.x + element.offsetrectangle.left;  controlloc.y = controlloc.y + element.offsetrectangle.top; 

4. set mouse position new location:

   cursor.position = controlloc; 

5. simulate mouse right-click:

   mousesimulator.clickrightmousebutton(); 

complete code:

public partial class form1 : form     {         public form1()         {             initializecomponent();          }          private void form1_load(object sender, eventargs e)         {              webbrowser1.documenttext = "<button class=\"mybtn\" type=\"submit\"> right click";             webbrowser1.documentcompleted += new webbrowserdocumentcompletedeventhandler(webbrowser1_documentcompleted);         }          void webbrowser1_documentcompleted(object sender, webbrowserdocumentcompletedeventargs e)         {             foreach (htmlelement element in webbrowser1.document.getelementsbytagname("button"))             {                 if (element.getattribute("classname") == "mybtn")                 {                     point controlloc = this.pointtoscreen(webbrowser1.location);                     //get element posation                     controlloc.x= controlloc.x + element.offsetrectangle.left;                     controlloc.y = controlloc.y + element.offsetrectangle.top;                     cursor.position = controlloc;                     mousesimulator.clickrightmousebutton();                 }             }         }     }      public class mousesimulator     {         [dllimport("user32.dll", setlasterror = true)]         static extern uint sendinput(uint ninputs, ref input pinputs, int cbsize);          [structlayout(layoutkind.sequential)]         struct input         {             public sendinputeventtype type;             public mousekeybdhardwareinputunion mkhi;         }         [structlayout(layoutkind.explicit)]         struct mousekeybdhardwareinputunion         {             [fieldoffset(0)]             public mouseinputdata mi;              [fieldoffset(0)]             public keybdinput ki;              [fieldoffset(0)]             public hardwareinput hi;         }         [structlayout(layoutkind.sequential)]         struct keybdinput         {             public ushort wvk;             public ushort wscan;             public uint dwflags;             public uint time;             public intptr dwextrainfo;         }         [structlayout(layoutkind.sequential)]         struct hardwareinput         {             public int umsg;             public short wparaml;             public short wparamh;         }         struct mouseinputdata         {             public int dx;             public int dy;             public uint mousedata;             public mouseeventflags dwflags;             public uint time;             public intptr dwextrainfo;         }         [flags]         enum mouseeventflags : uint         {             mouseeventf_move = 0x0001,             mouseeventf_leftdown = 0x0002,             mouseeventf_leftup = 0x0004,             mouseeventf_rightdown = 0x0008,             mouseeventf_rightup = 0x0010,             mouseeventf_middledown = 0x0020,             mouseeventf_middleup = 0x0040,             mouseeventf_xdown = 0x0080,             mouseeventf_xup = 0x0100,             mouseeventf_wheel = 0x0800,             mouseeventf_virtualdesk = 0x4000,             mouseeventf_absolute = 0x8000         }         enum sendinputeventtype : int         {             inputmouse,             inputkeyboard,             inputhardware         }          public static void clickrightmousebutton()         {             input mousedowninput = new input();             mousedowninput.type = sendinputeventtype.inputmouse;             mousedowninput.mkhi.mi.dwflags = mouseeventflags.mouseeventf_rightdown;             sendinput(1, ref mousedowninput, marshal.sizeof(new input()));              input mouseupinput = new input();             mouseupinput.type = sendinputeventtype.inputmouse;             mouseupinput.mkhi.mi.dwflags = mouseeventflags.mouseeventf_rightup;             sendinput(1, ref mouseupinput, marshal.sizeof(new input()));         }     }
