Hi,
I want to create a dependency property for both Command and CommandParameter so that I can use these in controls that don't support Command and CommandParameter like textblock etc.
I have written and taken help from someone to create DP(dependency property) for Command and its working fine but for CommandParameter, I am not sure how to proceed.
My Code is as follows :-
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Interactivity;
using System.Windows;
using System.Windows.Input;
using System.Reflection;
using System.Windows.Controls;
namespace InteractivityHelper
{
public class InteractiveCommand : TriggerAction<DependencyObject>
{
protected override void Invoke(object parameter)
{
if (base.AssociatedObject != null)
{
ICommand command = this.ResolveCommand();
if ((command != null) && command.CanExecute(parameter))
{
command.Execute(parameter);
}
}
}
private ICommand ResolveCommand()
{
ICommand command = null;
if (this.Command != null)
{
return this.Command;
}
if (base.AssociatedObject != null)
{
foreach (PropertyInfo info in base.AssociatedObject.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
{
if (typeof(ICommand).IsAssignableFrom(info.PropertyType) && string.Equals(info.Name, this.CommandName, StringComparison.Ordinal))
{
command = (ICommand)info.GetValue(base.AssociatedObject, null);
}
}
}
return command;
}
private string _commandName;
public string CommandName
{
get
{
base.ReadPreamble();
return this._commandName;
}
set
{
if (this.CommandName != value)
{
base.WritePreamble();
this._commandName = value;
base.WritePostscript();
}
}
}
#region Command
public ICommand Command
{
get { return (ICommand)GetValue(CommandProperty); }
set { SetValue(CommandProperty, value); }
}
public ICommand CommandParameter
{
get { return (ICommand)GetValue(CommandParameterProperty); }
set { SetValue(CommandParameterProperty, value); }
}
public static readonly DependencyProperty CommandProperty =
DependencyProperty.Register("Command", typeof(ICommand), typeof(InteractiveCommand), new UIPropertyMetadata(null));
public static readonly DependencyProperty CommandParameterProperty =
DependencyProperty.Register("CommandParameter", typeof(ICommand), typeof(InteractiveCommand), new UIPropertyMetadata(null));
#endregion
}
}
Could someone please update my code and tell me how to proceed with the same ?
