C# WPF AnimationClock for DataGridCell FontWeight

I want to have a AnimationClock to change the datagridcell fontweight.
I already do it on color, and it is working well, see below's code.
ColorAnimation ca = new ColorAnimation(Colors.Black, Colors.Yellow, new Duration(TimeSpan.FromSeconds(3)));
ca.AutoReverse = true;
dataGridCell.Foreground = new SolidColorBrush(Colors.Black);
dataGridCell.Foreground.BeginAnimation(SolidColorBrush.ColorProperty, ca);
But for the fontWeight they didnt provide dataGridCell.FontWeight.BeginAnimation method.
So I have to do a ApplyAnimationClock.
And I do it in this way but it fails.
DoubleAnimation da = new DoubleAnimation(400.0, 600.0, new
Duration(TimeSpan.FromSeconds(3)));
da.AutoReverse = true;
AnimationClock ac = da.CreateClock();
dataGridCell.FontWeight = FontWeight.FromOpenTypeWeight(400);
dataGridCell.ApplyAnimationClock(DataGridCell.FontWeightProperty, ac);
I want to change the fontweight from 400 to 600. But it give me this exception below.
Additional information: AnimationTimeline of type 'System.Windows.Media.Animation.DoubleAnimation' cannot be used to animate the 'FontWeight' property of type 'System.Windows.FontWeight'.
My question is simple, I want to change the fontweight of the datagridcell, then after 3 seconds it turns back to normal. If there is a easy way to do this, please tell me.

Try using Bold property:
dataGridCell.FontWeight = FontWeight.Bold;

Set value of x:Uid programmatically

I am creating an AppBarButton in code behind file of XAML view.
Currently, I have AppBarButton defined in XAML as below:
<AppBarButton x:Name="SelectVisitAppBarButton" x:Uid="AppBar_TransferVisit" Margin="0,0,12,0" Icon="Bullets" Style="{StaticResource TransferAppBarButtonStyle}" IsEnabled="{Binding ScheduleViewVm.IsVisitSelectionEnable}" Click="SelectVisit_Click" />
I want to convert this XAML into C# code. Following is the code that I have till now.
AppBarButton SelectVisitAppBarButton = new AppBarButton();
SelectVisitAppBarButton.Margin = new Thickness(0, 0, 12, 0);
SymbolIcon bulletSymbol = new SymbolIcon();
bulletSymbol.Symbol = Symbol.Bullets;
SelectVisitAppBarButton.Icon = bulletSymbol;
SelectVisitAppBarButton.Style = App.Current.Resources["TransferAppBarButtonStyle"] as Style;
SelectVisitAppBarButton.Click += SelectVisit_Click;
Binding b = new Binding();
b.Source = _viewModel.ScheduleViewVm.IsVisitSelectionEnable;
SelectVisitAppBarButton.SetBinding(Control.IsEnabledProperty, b);
Appbar.Children.Add(SelectVisitAppBarButton);
The only thing I am looking for is to convert x:Uid="AppBar_TransferVisit" into its equivalent C# code. Any help on this is highly appreciated.
Thanks,
Naresh Ravlani.

It seems that you cannot actually set the x:Uid attribute programmatically in UWP:
How to set control x:Uid attribute programmatically for a metro app control?
This is because it's a XAML directive rather than a property:
Doing localization in visualstatemanager by changing x:uid?
You will have to set the corresponding properties of the AppBarButton directly, e.g.:
AppBarButton SelectVisitAppBarButton = new AppBarButton();
var resourceLoader = Windows.ApplicationModel.Resources.ResourceLoader.GetForCurrentView();
var text = resourceLoader.GetString("SomeResource");
AppBarButton SelectVisitAppBarButton = new AppBarButton();
SelectVisitAppBarButton.Content = text;

I can confirm that I have spoken to the UWP-XAML platform team about programatically accessing x:UID and it is not possible. This is a shortcoming, if you ask me. But it is what it is at this time. :)

There's a workaround, using XamlReader to load the button from xaml.
Button btn = (Button)XamlReader.Load("<Button xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml' x:Uid='btnSubmit' Margin='5,0,0,0'/>");
btn.OtherProperty = xxxx

Setting the Datacontext of a dynamically created control

I have a UserControl (Map) that contains a Canvas control. I am dynamically adding a control (Gate) to this canvas from the code behind.
I want the Gate objects DataContext to be the "Gate" property of the Map's DataContext. This is being done in the code behind.
Binding dataContextBinding = new Binding();
dataContextBinding.RelativeSource = new RelativeSource(RelativeSourceMode.Self);
dataContextBinding.Path = new PropertyPath("DataContext.SelectedLevelModule.Gate");
dataContextBinding.Mode = BindingMode.TwoWay;
dataContextBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;
BindingOperations.SetBinding(gate, DataContextProperty, dataContextBinding);
After this block of code runs, the gate.DateContext is null...
Any ways this can be done? Drawing a blank..
Thanks

You are setting the property path to DataContext.SelectedLevelModule.Gate. You are then assigning the binding to the DataContextProperty. I think what is happening is that the path is now gate.DataContext.DataContext.SelectedLevelModule.Gate.
Try removing DataContext from your PropertyPath and see if that fixes it. You are already assigning it to the DataContext, you should not have to specify it in the Path.
var dataContextBinding = new Binding();
dataContextBinding.Path = new PropertyPath("SelectedLevelModule.Gate");
BindingOperations.SetBinding(gate, DataContextProperty, dataContextBinding);

Cell Style Binding does not Update on Value Change

I have a DataGrid which is bound to a Collection of Objects. Every DataGridColumn is created in code behind.
The Background of these columns is dependent on different values of the object. I create the background binding in the CellStyle (as it should not override default style's from triggers).
var backgroundBinding = new Binding
{
Converter = new MyBindingConverter(),
ConverterParameter = new MyConverterParameter()
};
cellStyle.Setters.Add(new Setter(Control.BackgroundProperty, backgroundBinding));
As you can see it binds directly to the element. As different value are changing the value of the Columns is updated accordingly, but the converter of the Binding is not called.
I tried calling OnPropertyChanged(null) to show that the object was updated, but sadly this does not work.

Did you try to specify Path for backgroundBinding? Something like:
var backgroundBinding = new Binding
{
Converter = new MyBindingConverter(),
ConverterParameter = new MyConverterParameter(),
ElementName = YourElementName,
Path = PropertyOnElement
};
cellStyle.Setters.Add(new Setter(Control.BackgroundProperty, backgroundBinding));

How do you set binding of ComboBox ItemsSource in UserControl?

Here is the combobox in my UserControl:
<Combobox ItemsSource="{Binding ComboItemsProperty}" />
I have tried:
Binding bind = new Binding();
bind.Mode = BindingMode.OneWay;
bind.Source = this;
bind.Path = new PropertyPath("ComboItemsProperty");
this.SetBinding(ComboBox.ItemsSourceProperty, bind);
However, this doesn't work. I think I am doing the bind.Source wrong, but I'm not sure what to set the Source to. This code is inside my UserControl.xaml.cs.

You can try (Replace this)
Binding bind = new Binding();
bind.Mode = BindingMode.OneWay;
bind.Source = yourCollectionSourceOrClass; //<--Replace with your collection
bind.Path = new PropertyPath("ComboItemsProperty");
this.SetBinding(ComboBox.ItemsSourceProperty, bind);

You need to the set context of the instance containing your property ComboItemsProperty. So instead of 'this' u should set it to 'this.DataContext' or other class object instance containing the ItemSource property you have defined..
Try this,
Binding bind = new Binding();
bind.Mode = BindingMode.OneWay;
bind.Source = this.DataContext;
bind.Path = new PropertyPath("ComboItemsProperty");
this.SetBinding( ComboBox. ItemsSource Property, bind);
(posting frm mobile)

I have tried a lot of ways to do this, however, nothing seems to work.
I am instead going to serialize the binding when the .xaml file gets saved out. This seems to be working perfectly. Binding will no longer have to be set in code.
