http://blogs.msdn.com/b/vinsibal/archive/2009/04/07/5-random-gotchas-with-the-wpf-datagrid.aspxSince the release of the WPF DataGrid there have been several common patterns of questions that developers were asking on the discussion list . I thought that I would capture some of that here so it would be easy to find. I'll also try to keep it as shorten-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/vinsibal/archive/2009/04/07/5-random-gotchas-with-the-wpf-datagrid.aspx#9941126Fri, 25 Dec 2009 10:59:36 GMT91d46819-8472-40ad-a661-2c78acb4018c:9941126Amit<p>I have a WPF toolkit datagrid with &quot;AutoGenerateColumns&quot; as TRUE.

If possible, could you also sometime summarize the intended commit behavior at row level ... or have it explained in the forthcoming documentation ?</p> <p>With regards to a row what is the standard datagrid behavior and its possible adaptations, assuming NewItemPlaceholderPosition.AtEnd:</p> <p>- (1) when creating a new row :</p> <p> - (a) is the row committed by 'enter' and/ or by 'tab' (*) ?</p> <p> - (b) if the row is committed only by 'enter' (e.g.), is it possible to commit it with 'tab'; if yes what is the recommended manner of doing ? (previewkeydown override 'tab' to 'enter' in the last editable cell ?)</p> <p> &nbsp;(c) if the user uses another key like 'arrow up/down/right/left' or 'skip/tab', should the row loose focus and commit as well ?</p> <p> - (d) when entering the next row after commit, the standard behavior is for the datagrid to set focus in the same column; is it ok to force the first (or any other) editable cell to get focus; &nbsp;if yes what is the recommended manner of doing ?</p> <p>- (2) same questions when updating an existing row</p> <p>Thanks so much,</p> <p>Julie</p> <p>(*) 'tab' means in this context that the datagrid will, when on the last possible editable cell (brought into view), skip over any 'IsReadOnly' column (even invisible and virtualized), out of the row to the next row</p><div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=9537797" width="1" height="1">http://blogs.msdn.com/b/vinsibal/archive/2009/04/07/5-random-gotchas-with-the-wpf-datagrid.aspx#9536539Tue, 07 Apr 2009 22:38:06 GMT91d46819-8472-40ad-a661-2c78acb4018c:9536539DotNetKicks.com<p>You've been kicked (a good thing) - Trackback from DotNetKicks.com</p> <img src="http://blogs.msdn.com/aggbug.aspx?PostID=9536539" width="1" height="1">http://blogs.msdn.com/b/vinsibal/archive/2009/04/07/5-random-gotchas-with-the-wpf-datagrid.aspx#9536006Tue, 07 Apr 2009 17:26:12 GMT91d46819-8472-40ad-a661-2c78acb4018c:95360065 Random Gotchas with the WPF DataGrid | ASP NET Hosting<p>PingBack from <a rel="nofollow" target="_new" href="http://asp-net-hosting.simplynetdev.com/5-random-gotchas-with-the-wpf-datagrid/">http://asp-net-hosting.simplynetdev.com/5-random-gotchas-with-the-wpf-datagrid/</a></p> <img src="http://blogs.msdn.com/aggbug.aspx?PostID=9536006" width="1" height="1">
