How to realize Web control's context menu by c#

[nakey_yang]

:zzz:somebody tell me can use IDocHostUIHandler can relize this idea,but how can do this by c#? ok

[Nick Parker]

IDocHostUIHandler is defined in the MsHtmHst.idl file. Basic idea is you can write your own idl file and use the midl compiler to generate the type library. Following that you can use the .NET Framework's command line tool tlbimp to generate a .NET assembly you can include within your application.

library WebInterop
{
import "MsHtmHst.idl";
enum tagDOCHOSTUIDBLCLK;
enum tagDOCHOSTUIFLAG;
enum tagDOCHOSTUITYPE;
interface ICustomDoc;
interface IDocHostShowUI;
interface IDocHostUIHandler;
interface IDocHostUIHandler2;
interface IHostDialogHelper;
}

Then create the type library:

midl WebInterop.idl /tlb bin\WebInterop.tlb

Then create the .NET assembly:

tlbimp bin\WebInterop.tlb /out:bin\WebInterop.dll

Now create a class that inherits from IDocHostUIHandler and of course implements the appropriate methods. - Nick Parker
