You can create a subclass of binding (e.g. CultureAwareBinding) which sets the ConverterCulture automatically to the current culture when created. It’s not a perfect solution, but it’s probably the only one, since retroactively forcing Binding to respect the culture could break other code in WPF which depends on this behavior. Let me know if you … Read more
Try this: Name your listbox Update the CommandParameter to: CommandParameter=”{Binding ElementName=listBox1,Path=SelectedItem}”
The solution for the problem, finally, is to use following syntax: Path=Item.(myNameSpace:IEdge.Tag).caption The previous code cast Item to the type IEdge in order to access the Tag property. In case of multiple nested casts the global pattern is : Path=Obj1.(ns1:TypeObj1.Obj2).(ns2:TypeObj2.Obj3)…(nsN:TypeObjN.BindedProp) As suggested in comments Do not use shorthand binding syntax when using this solution. Ensure … Read more
Create a function whose sole purpose is to return a computed observable. It may take in parameters as you wanted. It will have to be a separate computed observable if you want it to be a two-way binding. Then in your binding, call that function with the appropriate arguments. The computed observable it returns will … Read more
Unfortunetly no, you can’t bind to a ConverterParameter. There’s two options I’ve used in the past: instead of using a Converter, create a property on your ViewModel (or whatever you’re binding to) which does the conversion for you. If you still want to go the Converter route, pass the entire bound object to the converter … Read more
This is based on @AndyG’s answer but is a bit safer because it’s strongly typed. Implement an IValueConverter named DataTypeConverter, which accepts an object and returns its Type (as a System.Type): public class DataTypeConverter:IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { return value?.GetType() ?? Binding.DoNothing; } public object ConvertBack(object value, … Read more
May be a specific example will help. Let us take the host language as Python and the guest language as C. This means that Python will be calling C functions. The first option is to write the C library in a particular way. In the case of Python the standard way would be to have … Read more
How can I wait for ServiceConnection.onServiceConnected being called reliably? You don’t. You exit out of onCreate() (or wherever you are binding) and you put you “needs the connection established” code in onServiceConnected(). Are all the event handlers: Activity.onCreate, any View.onClickListener.onClick, ServiceConnection.onServiceConnected, etc. actually called in the same thread Yes. When exactly is ServiceConnection.onServiceConnected actually going … Read more
I’m not sure if this has been fixed in .NET 4, but WPF has never picked up the current culture when rendering things like currency or dates. It’s something I consider a massive oversight, but thankfully is easily corrected. In your App class: protected override void OnStartup(StartupEventArgs e) { FrameworkElement.LanguageProperty.OverrideMetadata( typeof(FrameworkElement), new FrameworkPropertyMetadata( XmlLanguage.GetLanguage( CultureInfo.CurrentCulture.IetfLanguageTag))); … Read more
Use a BindingList and set the DataPropertyName-Property of the column. Try the following: … private void BindGrid() { gvFilesOnServer.AutoGenerateColumns = false; //create the column programatically DataGridViewCell cell = new DataGridViewTextBoxCell(); DataGridViewTextBoxColumn colFileName = new DataGridViewTextBoxColumn() { CellTemplate = cell, Name = “Value”, HeaderText = “File Name”, DataPropertyName = “Value” // Tell the column which property … Read more
