XBAP Gadget

=?Utf-8?B?U3RldmVuIFRhbmc=?=

I'm creating WPF gadget by embed XBAP Iframe:
1. Is it possible that create Pure WPF (non-XBAP) which could
auto dock into the Vista sidebar when dragging the WPF application
near Sidebar?
2. My current approach is using XBAP inside the iFram,
The problem I met in XBAP gadget is that it is difficult to set padding so
that the gadget could be
drag out of the sidebar. I.E., the size of my XBAP is 190X145, my html
launcher is
<html>
<head>
<title>XBAP Gadget</title>

<style>
body {
width:145;
height:190;
padding:0;
margin:0;
background:black;
}
</style>
</head>
<body>
<iframe height="190"
width="145"
src="XbapGadget.xbap" />
</body>
</html>

when it is running, it just dock into the sidebar and the drag handle will
not show up no matter cursor move to anywhere on the gadget. I tried
change the padding or margin, the drag handle did show up, but the
untransparentable background make the gadget pretty ugly.

Any hints to make an ideal WPF gadget?

Best Regards
Steven

Hello,

Welcome to Microsoft Newsgroup Support Service! My name is Marco Zhou. It's
my pleasure to work with you on this thread.

For your first question, the simple answer is no, there is an option to
wrap WPF content inside a Windows Forms UserControl, and expose this
UserControl as ActiveX control so that it could be consumable by HTML
container (aka sidebar container), but this is not a pure WPF solution. I
think you will be more successful if you choose Silverlight rather than WPF
because Silverlight provides much better and integrated support in HTML
interop.

For your second question, I don't fully understand which issue you are
referring to, in particular what you mean by "drag out of the sidebar". If
you mean that the hosted XBAP content cannot be stretched to fill its
available space as its neighboring HTML content does, then this is a known
issue.

When hosting WPF content in native container such as Windows Vista sidebar
container, due to the fact that WPF uses device independent pixels, but the
native HTML container use physical pixels, so both of WPF content and
native HTML content will be stretched up and down unequally. One simple fix
is to use System.Windows.Controls.Viewbox control to wrap the root element
of WPF content, so that the content can be stretched out as it is.

If you have any further questions on this issue, free feel to ask here, we
are glad to answer them.

Hi Marco,
Thank you very much for answering my question. The reason that I didn't
use
Silverlight is that my gadget will talk to non-clr version native DLL to
retrieve
some video data, and SL doesn't support this. Am I right?
The issue I mentioned before was that the Gadget would just dock inside
the sidebar
and it could not draggable by using padding = 0 and margin = 0, If I adjust
the padding or/and margin value bigger than 0, there will be a border with
the gadget where could show drag handle, but the border is not transparent
and it ruins the
visual of the Gadget.
<style>
body {
width:145;
height:190;
padding:0;
margin:0;
background:black;
}

If using Viewbox control to wrap the root of WPF content, will the
Gadget still
draggable and without visual ruined? Could you explain more detail on how to
do this?

All the best.
