http://blogs.msdn.com/b/jpricket/archive/2012/01/12/tfs-2010-using-a-typeconverter-to-display-your-custom-process-parameter-list-type.aspxI just helped someone today with this common problem... "How do I get my custom list process parameter to show something besides '(Collection)' in the Process Parameter property grid?" The answer is really simple if you are familiar with the WinFormsen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/jpricket/archive/2012/01/12/tfs-2010-using-a-typeconverter-to-display-your-custom-process-parameter-list-type.aspx#10264494Mon, 06 Feb 2012 17:15:59 GMT91d46819-8472-40ad-a661-2c78acb4018c:10264494Georg Drobny - MSFT<p>Thanks Jason, you helped me a lot. :-)</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10264494" width="1" height="1">http://blogs.msdn.com/b/jpricket/archive/2012/01/12/tfs-2010-using-a-typeconverter-to-display-your-custom-process-parameter-list-type.aspx#10258176Wed, 18 Jan 2012 18:55:09 GMT91d46819-8472-40ad-a661-2c78acb4018c:10258176Jason Prickett - MSFT<p>Hi Sylvain,</p> <p>Try the Required property in the Metadata for the process parameter. </p> <p>See <a rel="nofollow" target="_new" href="http://blogs.msdn.com/b/jpricket/archive/2009/12/23/tfs-2010-custom-process-parameters-part-2-metadata.aspx">blogs.msdn.com/.../tfs-2010-custom-process-parameters-part-2-metadata.aspx</a> for more information.</p> <p>Thanks,</p> <p>Jason</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10258176" width="1" height="1">http://blogs.msdn.com/b/jpricket/archive/2012/01/12/tfs-2010-using-a-typeconverter-to-display-your-custom-process-parameter-list-type.aspx#10258164Wed, 18 Jan 2012 18:20:38 GMT91d46819-8472-40ad-a661-2c78acb4018c:10258164Sylvain Lavoie - McKesson<p>Nice post!</p> <p>How may I have the validation to display the yellow triangle like MS.
