This indicates to the ScrollViewer that its content is not capable of managing scrolling itself, and that ScrollViewer needs to do all the work.<BR/><BR/>Hope that helpsSamhttp://www.blogger.com/profile/01345100698738870730noreply@blogger.comtag:blogger.com,1999:blog-7577421612120825312.post-18276285146007524192009-02-14T02:20:00.000Z2009-02-14T02:20:00.000ZSam,<BR/> In a typical GANTT chart, ala MS Project, the 'tasks' are listed on their own lines. I modified the GantRowPanel to migrate the tasks both down and across. Now I have a singular problem, scrolling! I tried wrapping the ItemsControl in a ScrollViewer and that doesn't seem to do the trick for me. Any ideas? I'm sure I'm just missing some configuration for the ScrollViewer.<BR/><BR/>Thanks,!Bob Briggsnoreply@blogger.comtag:blogger.com,1999:blog-7577421612120825312.post-48945108343918842772008-12-07T17:22:00.000Z2008-12-07T17:22:00.000ZSam,<BR/> I really like what you've done here. I have read both installments and I'm eager to get into the display of an actual GANTT chart! I think I understand how I can use the GantRowPanel in a DataTemplate for my task list objects to produce a panel in a range in, say, a listbox control. All of that would be great, but I'm anxious to figure out how to provide a timescale header to such a display. I'm thinking that a timescale header will display a complete range output control that has it's size fixed in the MeasureOverride() and will include properties to identify the pixelsize of each date increment. Is this the correct path to take?<BR/><BR/>Thanks again for a great article!Bob Briggsnoreply@blogger.comtag:blogger.com,1999:blog-7577421612120825312.post-62808186225872612992008-11-21T17:31:00.000Z2008-11-21T17:31:00.000ZAnonymous,<BR/> I know that a couple of Gantt controls have come to the market since I created mine two years ago.
