ItemsControl ItemTemplate Binding

Are you sure the code you posted here IS the code you use in your solution? Because, this code works for me : XAML <ItemsControl ItemsSource=”{Binding}”> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel> <TextBlock Text=”{Binding OwnerData.OwnerName}”></TextBlock> <TextBlock Text=”{Binding Credit}” /> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> Window’s Loaded Event ObservableCollection<ForDisplay> items = new ObservableCollection<ForDisplay>(); for (int i = 0; i < … Read more

Backbone.js Event Binding

jQuery’s habit of setting this to whatever happens to be convenient at the time is a pretty nasty pattern, in my opinion — fortunately, you never have to rely on it: onClick: function(e) { this; // Still the view instance (as it should be). e.target; // The element that was clicked. e.currentTarget; // The element … Read more

Binding ElementName. Does it use Visual Tree or Logical Tree

I think it’s logical tree. When using ControlTemplates, you’re replacing one visual tree with another, but I don’t think you can reference the names defined inside of the ControlTemplate. For example: <Page xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml”> <Grid> <Grid.Resources> <ControlTemplate x:Key=”Foo” TargetType=”Button”> <Border x:Name=”border” Background=”Red”> <Label Content=”{TemplateBinding Content}”></Label> </Border> </ControlTemplate> </Grid.Resources> <Grid.ColumnDefinitions> <ColumnDefinition></ColumnDefinition> <ColumnDefinition></ColumnDefinition> </Grid.ColumnDefinitions> <Button x:Name=”buttonFoo” Background=”Green” … Read more

Problems with binding to Window Height and Width

Try using two way binding, it worked for me: Width=”{Binding Path=xExt, Mode=TwoWay}”

xjc: Two declarations cause a collision in the ObjectFactory class

I’ll quote from the most official unofficial guide on JAXB on the net. When schemas contain similar looking element/type names, they can result in “Two declarations cause a collision in the ObjectFactory class” errors. To be more precise, for each of all types and many elements (exactly what elements get a factory and what doesn’t … Read more

Handling null when binding to an Image in XAML

I used x:Null with TargetNullValue, that way you get an easy blank image… <Image Source=”{Binding LogoPath, TargetNullValue={x:Null}}” /> That way you don’t need to mess around with Triggers or BitmapImages as static resources.

WPF binding with StringFormat doesn’t work on ToolTips

ToolTips in WPF can contain anything, not just text, so they provide a ContentStringFormat property for the times you just want text. You’ll need to use the expanded syntax as far as I know: <TextBox …> <TextBox.ToolTip> <ToolTip Content=”{Binding ElementName=myTextBlock,Path=Text}” ContentStringFormat=”{}It is: {0}” /> </TextBox.ToolTip> </TextBox> I’m not 100% sure about the validity of binding … Read more

A TwoWay or OneWayToSource binding cannot work on the read-only property

It’s hard to guess without code, but you should be able to set the BindingMode to OneWay. <TextBox Text=”{Binding Path=MyProperty, Mode=OneWay}” /> or from code: Binding binding = new Binding(); binding.Mode = BindingMode.OneWay;

MvvmCross Android – Alternative to RelativeSource binding for button command

See the second option in the answer in MVVMCross changing ViewModel within a MvxBindableListView – this covers one way to do this. Using that approach you’d expose a list of objects like: public class Wrapped { public ICommand GoThruCommand { get; set; } public ICommand OpenCommand { get; set; } public string Name { get; … Read more

What is the difference between a let-rebinding and a standard assignment?

The second let x introduces a second binding that shadows the first one for the rest of the block. That is, there are two variables named x, but you can only access the second one within the block statement after the let x = 12; statement. These two variables don’t need to have the same … Read more
