hi my application is of type Silverlight. i want to trigger when user clicks on the border of the browser. for this purpose, i used this method:

C#

public MainPage()
{
    InitializeComponent();
    bool bResult = System.Windows.Browser.HtmlPage.Window.AttachEvent("onmousedown", new EventHandler(this.eventHandler));
}

private void eventHandler(object sender, EventArgs e)
{
    ...
}

but the eventHandler is not called. why?
ps1. if i change "onmousedown" to "onresize" it's called.
ps2. bResult is true in both cases.

Clicking on the border will not generate an onmousedown event. The border does not belong to browser windows client area so no event will be generated. If you resize the window though, the client area will also change and thus the container for the root element resizes which triggers an onresize event.

Hope that clears it up a bit!

Cheers!

so how can i grab the mouse events belong to the non-client area parts of the browser?
indeed i need to know when use release the left mouse button (mouse up). by this method i want to know when resize is done.

1. Grabbing non client area mouseevents is IMHO impossible for browser based applications.
2. I'm not sure when a resize event is acutally fired. If the resize is only fired after the mouse button has been released then you'd also have the end of your resize operation. If the resize is being fired continually there is no way I know of to tell that the user finally stopped resizing the window by releasing the mouse button.

thank u for ur answer
resize is continually generated.
the fact is that the event might be raised, because we've ResizeEnd in a form application and essentially all windows receive WM_EXITSIZEMOVE and this could not be neglected. this is the fault of MS that it doesn't capture the message and dispatch it throw Silverlight.
but, since the message EXISTS, there must be a way or workaround to write an unmanaged code to capture it.
any suggestion?

That is correct, a 5.
