What is the proper way to do binding on a ux:Name? I get the warning:
'{name}' contains the character '{' which is not a valid Uno identifier character. This may lead to problems when accessing the symbol from Uno code.
this the part of the js code that produces the warning:
<Each Items="{circles}">
<Circle ux:Name="{name}" Fill="#FFFFFF" Width="10"/>
<!-- more code, not relevant -->
</Each/>
What is the correct way to do binding on the ux:Name, to keep the compiler happy?
You can’t define the ux:Name at runtime, that is done at compile time, only the Name property can be set at runtime

Are there any performance tradeoffs by doing this? Setting it at runtime instead compile time.

Ok I got it, I will use ‘Name’ instead og ux:Name, thanks for the help.

Not really a performance concern.
Names not known at compile time cannot be referred to at compile time, like in a <Change> or <Set>
When i try to bind to Name
<Each Items="{questionData.button}"> <Rectangle Height="50" Margin="{margin}" Width="150" Fill="#2D4059" Name="{id}" >
<Tapped>
<Callback Handler="{buttonClick}"/>
</Tapped>
<Text Value="{name}" TextColor="#fff" Alignment="Center" Padding="10,0,10,0" /> <DropShadow Color="#000" Size="10" Distance="2" />
</Rectangle>
</Each>
What i get is this error : The given key was not present in the dictionary.
However app does work on start, but after i press CTRL+S in my editor it crashes with this error.
metallica: That means that the key you are binding to, does not exist in the datacontext. If you have further problems you should open a new thread and show more of your code.
