My solution, from nikmd23’s jQuery snippet but with the blur() function that seems to work better $(‘input[readonly]’).focus(function(){ this.blur(); }); Example here: http://jsfiddle.net/eAZa2/ Don’t use the attribute “disabled” because the input would not be submitted when it is part of a form Sounds like a bug! There is a similar bug (396542) open with Mozilla, saying … Read more
The admin is for editing, not just viewing (you won’t find a “view” permission). In order to achieve what you want you’ll have to forbid adding, deleting, and make all fields readonly: class MyAdmin(ModelAdmin): def has_add_permission(self, request, obj=None): return False def has_delete_permission(self, request, obj=None): return False (if you forbid changing you won’t even get to … Read more
You can expose it AsReadOnly. That is, return a read-only IList<T> wrapper. For example … public ReadOnlyCollection<int> List { get { return _lst.AsReadOnly(); } } Just returning an IEnumerable<T> is not sufficient. For example … void Main() { var el = new ExposeList(); var lst = el.ListEnumerator; var oops = (IList<int>)lst; oops.Add( 4 ); // … Read more
var di = new DirectoryInfo(“SomeFolder”); di.Attributes &= ~FileAttributes.ReadOnly;
Tuples originated in functional programming. In (purely) functional programming, everything is immutable by design – a certain variable only has a single definition at all times, as in mathematics. The .NET designers wisely followed the same principle when integrating the functional style into C#/.NET, despite it ultimately being a primarily imperative (hybrid?) language. Note: Though … Read more
Use ReadOnlyCollection<T>. It is read-only and, contrary to what you believe, it has an indexer. Arrays are not immutable and there is no way of making them so without using a wrapper like ReadOnlyCollection<T>. Note that creating a ReadOnlyCollection<T> wrapper is an O(1) operation, and does not incur any performance cost. Update Other answers have … Read more
As stated in the new C# 9 features post, The one big limitation today is that the properties have to be mutable for object initializers to work: They function by first calling the object’s constructor (the default, parameterless one in this case) and then assigning to the property setters. However, value types with readonly modifiers … Read more
You could write your own read-only wrapper for the dictionary, e.g.: public class ReadOnlyDictionaryWrapper<TKey, TValue, TReadOnlyValue> : IReadOnlyDictionary<TKey, TReadOnlyValue> where TValue : TReadOnlyValue { private IDictionary<TKey, TValue> _dictionary; public ReadOnlyDictionaryWrapper(IDictionary<TKey, TValue> dictionary) { if (dictionary == null) throw new ArgumentNullException(“dictionary”); _dictionary = dictionary; } public bool ContainsKey(TKey key) { return _dictionary.ContainsKey(key); } public IEnumerable<TKey> Keys … Read more
Thank you for you suggestion Panoptik, adding readonly on focusin, and then removing it on focusout was the cleanest way, million thanks! I answer myself in case anyone has the same problem. Hope it helps. $(document).on(“focusin”, “#someid”, function() { $(this).prop(‘readonly’, true); }); $(document).on(“focusout”, “#someid”, function() { $(this).prop(‘readonly’, false); });
HTML5 spec: http://www.w3.org/TR/html5/forms.html#attr-input-readonly : The readonly attribute is a boolean attribute http://www.w3.org/TR/html5/infrastructure.html#boolean-attributes : The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value. If the attribute is present, its value must either be the empty string or a value that is an … Read more
