I create a Visual C# Windows Forms Control Library project in VS 2008
click the events icon and double click the Load field. AUserControl_Load method
is written which I modify as follows.
private void UserControl1_Load(object sender, EventArgs e)
{
MessageBox.Show("It loads");
}
When I run the project it displays
It loads
When I drag and drop a WebBrowser to the UserConrtol and run it it does not display "It loads"
Why does this happen?

Ok, found an work around (not sure why it works though!)
If you set the webbrowser control (in the user control)property AllowWebBrowserDrop to false, then usercontrol_load method is called (and message box is displayed).

Thanks John. From your post I suspected that I had a corrupt system soI borrowed another machine, did a clean install of VS2008 and got the same results as before.
If I delete the web browser it again prints the "It loads" message.Adding it back I see no message. |

I am using VS2005 Professional. Let me test on C# Express 2008 |

The problem is reproducible in both VS 2005 and VS 2008 Express.
It seems when we have a web browser control in a user control, the usercontrol_load method is not called. Not sure if it's an issue with web browser controland has it been mentioned some where in MSDN.

Can you send me your usercontrol to look at? |
