What is the correct way to bind a checkbox and have an event fire when that checkbox changes? I have tried a couple of different ways all not working exactly as I had hoped. Note the checkbox is in a component.
<input type="checkbox" checked="@IsChecked" @onchange="CheckboxChanged">@code{ [Parameter] public bool IsChecked { get; set; } = true; private void CheckboxChanged() { Console.WriteLine($"Checkbox changed {IsChecked}"); }}When the page loads it reads the value that is given to IsChecked, and when the CheckBox is checked the method fires. However, the value for IsChecked is not updated. Then if the binding value for IsChecked is changed outside of the component, the method does not fire but the value for IsChecked is changed (should note that UI is updated correctly).
I figured I needed an actual bind like this:
<input type="checkbox" @bind="IsChecked" @onchange="CheckboxChanged" >However, this gives an error that onchange is used two or more
<input type="checkbox" @bind="IsChecked" @onclick="CheckboxChanged" >When the user clicks the checkbox it does fire the method however, IsChecked is at the old value (I am assuming the click happens before the bind). Then if the value for IsChecked is changed outside of the component, once again the method does not fire.
What is the correct way?
