<div dir="ltr" align="left"><span><font color="#0000ff" face="Arial" size="2">I ran into
the same problem you are experiencing a few months ago while using Python
1.1. The problem is that the WinForms reflection is looking for static
properties. IronPython 1.1 objects, being dynamic, lack the proper
metadata to guide the WinForms classes to do the right
thing.</font></span></div>
<div dir="ltr" align="left"><span><font color="#0000ff" face="Arial" size="2"></font></span> </div>
<div dir="ltr" align="left"><span><font color="#0000ff" face="Arial" size="2">Try <a href="http://1.1.1." target="_blank">1.1.1.</a> That will allow WinForms
to find a *whole* lot of things (including all your public methods). My
guess is that it may be easier for you to turn off these extra elements rather
than to create a separate C# assembly to hold static
interfaces.</font></span></div>
<div dir="ltr" align="left"><span><font color="#0000ff" face="Arial" size="2"></font></span> </div>
<div dir="ltr" align="left"><span><font color="#0000ff" face="Arial" size="2">It would
be great to clean up these staticized properties in 1.1.2 to include only
properties defined with the "property" function. That would really help
anyone using static data binding in WinForms (or any other part of the BCL for
that matter).</font></span></div>

System.Windows.Forms.PropertyGrid and Python objects<br></font><br></div>
<div>
<div></div>
<div>
<div></div>So I've been through hell last night tearing my hear out trying to
figure out how to work PropertyGrid properly with a Python class
object.<br><br>Things I've tried:<br><br>1) In Python,
PropertyGrid.SelectedObject = pythonobj <br>2) In Python, Deriving
PropertyGrid and overriding CreatePropertyTab<br>3) In C#, deriving a new
class from PropertyGrid and implementing<br><br>public void
SetPythonObject(Object obj)<br>{<br> this.SelectedObject =
obj;<br>}<br><br><br>4) In C#, Overriding CreatePropertyTab() (I get a warning
about hiding a baseclass implementation -- sounds like this isn't
overrideable)<br>5) In C#, creating a wrapper class:<br><br>class
CustomHolder<br>{<br> private Object heldObj = null;<br> public
Object held {<br> get { return heldObj;
}<br> set { heldObj = value; }<br> }<br>
CustomHolder(Object obj) <br> {<br> this.held =
obj;<br> }<br>}<br><br>and in the derived PropertyGrid
class:<br><br>public void SetPythonObject(Object obj)<br>{<br>
this.SelectedObject = new CustomHolder(obj);<br>}<br><br>--<br><br>Only #5 so
far has done anything worthwhile: In the property grid as a single field I get
what looks like str(obj) output:<br><module.CLASSNAME instance at
0x................><br><br>I've also considered using the TypeDescriptor()
class/methods to create each property grid entry myself, but I don't see
anything at all about where PropertyGrid gets its property fields from -- see
#4.<br><br>Is there any way to do this conveniently (I'd prefer not to write a
C# custom dll, but am amiable to the requirement of doing so)?<br><br>Chuck
