EditBox Text Property

How can you push a string to the EditBox control from say a button control. For instance, i would like to click on a button in the addin ribbon that would send a string to the EditBox text property.

Here are two ways to do it. One uses an event which keeps the button and edit box loosely coupled, the other uses a direct reference where the button updates the edit box directly. The loosely coupled is the most flexible but is a bit more work than simply updating the edit box text - and, if that is literally all u need, then its overkill.

public class DateTimeStringChangedEventArgs : EventBase { public string OldDateTimeString { get; private set; } public string NewDateTimeString { get; private set; } public DateTimeStringChangedEventArgs(string oldDateTimeString, string newDateTimeString) { OldDateTimeString = oldDateTimeString; NewDateTimeString = newDateTimeString; } } public class DateTimeStringChangedEvent : CompositePresentationEvent<DateTimeStringChangedEventArgs> { public static SubscriptionToken Subscribe( Action<DateTimeStringChangedEventArgs> action, bool keepSubscriberReferenceAlive = false) { return FrameworkApplication.EventAggregator.GetEvent<DateTimeStringChangedEvent>() .Register(action, keepSubscriberReferenceAlive); } public static void Unsubscribe(Action<DateTimeStringChangedEventArgs> subscriber) { FrameworkApplication.EventAggregator.GetEvent<DateTimeStringChangedEvent>() .Unregister(subscriber); } public static void Unsubscribe(SubscriptionToken token) { FrameworkApplication.EventAggregator.GetEvent<DateTimeStringChangedEvent>() .Unregister(token); } internal static void Publish(DateTimeStringChangedEventArgs payload) { FrameworkApplication.EventAggregator.GetEvent<DateTimeStringChangedEvent>() .Broadcast(payload); } } internal class Module1 : Module { private static Module1 _this = null; private string _dateTimeString = DateTime.Now.ToString("G", CultureInfo.CurrentCulture); public string DateTimeString { get { return _dateTimeString; } set { var args = new DateTimeStringChangedEventArgs( _dateTimeString, value); _dateTimeString = value; //Raise the event DateTimeStringChangedEvent.Publish(args); } } public EditBoxDirectApproach EditBoxDirectApproach { get; set; } = null; ... } internal class Button1 : Button { protected override void OnClick() { var date_string = DateTime.Now.ToString("G", CultureInfo.CurrentCulture); //Indirect, loose-coupling Module1.Current.DateTimeString = date_string; //Direct, direct-coupled Module1.Current.EditBoxDirectApproach.Text = date_string; } } internal class EditBoxIndirectApproach : EditBox { public EditBoxIndirectApproach() { Initialize(); } private bool _ignoreEvents = false; private void Initialize() { //This will invoke OnTextChange which is ok //as we havent subscribed to the event yet this.Text = Module1.Current.DateTimeString; DateTimeStringChangedEvent.Subscribe((args) => { _ignoreEvents = true; try { //Invokes OnTextChange this.Text = args.NewDateTimeString; } finally { _ignoreEvents = false; } }); } protected override void OnTextChange(string text) { //prevent (infinite) recursion if (_ignoreEvents) return; Module1.Current.DateTimeString = text; base.OnTextChange(text); } } internal class EditBoxDirectApproach : EditBox { public EditBoxDirectApproach() { Module1.Current.EditBoxDirectApproach = this; this.Text = DateTime.Now.ToString("G", CultureInfo.CurrentCulture); } }
