The correct approach in Angularjs is to use ng-value for non-string values of models. Modify your code like this: <label data-ng-repeat=”choice in question.choices”> <input type=”radio” name=”response” data-ng-model=”choice.isUserAnswer” data-ng-value=”true” /> {{choice.text}} </label> Ref: Straight from the horse’s mouth
You could try something like this: …Binding=”{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=DataContext.AllowItemCommand}” …
You can use a MultiBinding combined with the StringFormat property. Usage would resemble the following: <TextBlock> <TextBlock.Text> <MultiBinding StringFormat=”{}{0} + {1}”> <Binding Path=”Name” /> <Binding Path=”ID” /> </MultiBinding> </TextBlock.Text> </TextBlock> Giving Name a value of Foo and ID a value of 1, your output in the TextBlock would then be Foo + 1. Note: This … Read more
You can remove .selected from saveUsername in your checkbox input since saveUsername is a boolean. Instead of [(ngModel)] use [checked]=”saveUsername” (change)=”saveUsername = !saveUsername” Edit: Correct Solution: <input type=”checkbox” [checked]=”saveUsername” (change)=”saveUsername = !saveUsername”/> Update: Like @newman noticed when ngModel is used in a form it won’t work. However, you should use [ngModelOptions] attribute like (tested in Angular 7): … Read more
“If you use ng-model, you have to have a dot in there.” Make your model point to an object.property and you’ll be good to go. Controller $scope.formData = {}; $scope.check = function () { console.log($scope.formData.searchText.$modelValue); //works } Template <input ng-model=”formData.searchText”/> <button ng-click=”check()”>Check!</button> This happens when child scopes are in play – like child routes or … Read more
How would binding work for objects? How listening to change in the form might work? An abstraction that updates both objects I suppose there are other techniques, but ultimately I’d have an object that holds reference to a related DOM element, and provides an interface that coordinates updates to its own data and its related … Read more
A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like “details view”). It’s basically the multi-column listbox, the cousin of windows form’s listview. If you don’t need the additional … Read more
Kent wrote an interesting blog about this topic: View Models: POCOs versus DependencyObjects. Short summary: DependencyObjects are not marked as serializable The DependencyObject class overrides and seals the Equals() and GetHashCode() methods A DependencyObject has thread affinity – it can only be accessed on the thread on which it was created I prefer the POCO … Read more
You can further simplify the accepted answer. Instead of typing out the enums as strings in xaml and doing more work in your converter than needed, you can explicitly pass in the enum value instead of a string representation, and as CrimsonX commented, errors get thrown at compile time rather than runtime: ConverterParameter={x:Static local:YourEnumType.Enum1} <StackPanel> … Read more
If you want to bind to another property on the object: {Binding Path=PathToProperty, RelativeSource={RelativeSource Self}} If you want to get a property on an ancestor: {Binding Path=PathToProperty, RelativeSource={RelativeSource AncestorType={x:Type typeOfAncestor}}} If you want to get a property on the templated parent (so you can do 2 way bindings in a ControlTemplate) {Binding Path=PathToProperty, RelativeSource={RelativeSource TemplatedParent}} … Read more
