Argument 1: cannot convert from 'System.Windows.RoutedEventHandler' to 'System.Windows.RoutedEvent'
The best overloaded method match for'System.Windows.FrameworkElementFactory.AddHandler(System.Windows.RoutedEvent, System.Delegate)' has some invalid arguments
The event'FMG.UI.WPF.Shared.Views.Controls.AssignedEmployeesControl.AssignmentRemoved' can only appear on the left hand side of += or -= (except when used from within the type 'FMG.UI.WPF.Shared.Views.Controls.AssignedEmployeesControl')
I don't understand what's going on here. What's the right way to wire up my event?
Why doesn't this work? If you zoom in on the image at runtime, you'll notice that the top is red and the bottom is green, but at the transition between them, there is a dark line. It's my understanding that if you use the same offset for two colors, you'll get a hard break.
By my math, 0.611111111111111 * 18 = 11, so its not like I'm giving it half pixels or anything. If I use .5 / .5 for the offsets, I get a hard break.
I have 3 tables which are linked to each other with Primary and Foreign key relationship. When I use the datasource combinely for all the 3 tables unable to edit the records and Add option is not visible. What should be the resoultion
I normally Google for this kind of stuff, but I'm not sure of the proper name / terminology since I'm not really a math guy, so I'm not coming up with any hits...
I'm trying to draw a very simple "graph". 0,0 10,10 20,3 30,15, etc.
So, right now, I just add the points to a PolyLine and all is good.
But this results in a sharp zig-zag line... how do I make it into a "smoother" "wave" type line based on the same point array? The only term I remember from math class is bezier curves lol, but that doesn't seem to be what I'm looking for.
Hmm... I found some Petzold code that creates a canonical spline in WPF, seems like its working (doing what I want) unless I don't know what I'm talking about which is entirely possible since I don't know the diffs between all those splines haha. All I know is that it looks like a wave interpertation of my zig-zag line. Thanks!
I've got a WPF TreeView that is using the structure in Josh Smith's article[^]
In my case I've only got one type of object (Unit) that has a self-referencing hierarchy. So I only have one item ViewModel and so only the one HierarchicalDataTemplate.
Everything 'works', but there are two usability issues:
1) clicking on the expander can take a while, and there's nothing to indicate to the user that its happening.
2) the expanders appear on items that have no children (I assume due to the DummyChild that gets added.
For the 1st issue, I added a INPC property IsLoading to the base item VM TreeViewItemViewModel. Then I've been round and round in circles trying to get this working...at the moment I've got...
In my UnitTreeItemViewModel in the LoadChildren override I set IsLoading before and after.
IsLoading = true;
//sim a delay
foreach (Unit u in UnitCache.Units.AllUnits.Where(WhereClause))
base.Children.Add(new UnitTreeItemViewModel(u, this, _uh));
IsLoading = false;
Finally I added a simple TextBlock that I make visible based on IsLoading:
But all this does is show on the child items (after they appear), not the parent
I've tried changing it to set the Parent's IsLoading, but that didn't seem to work either, the root items don't have Parents for a start...
I have a wpf window which is a splash screen. I want it to be displayed for a certain time interval (say 5 sec) and then it closes and new login window opens.the problem is that in splash screen there are some process undergoing so if i call sleep() they stop working and mouse pointer shows busy symbol.
