Puede utilizar este ayudante para establecer el nombre dentro del control de usuario:
using System;
using System.Reflection;
using System.Windows;
using System.Windows.Media;
namespace UI.Helpers
{
public class UserControlNameHelper
{
public static string GetName(DependencyObject d)
{
return (string)d.GetValue(UserControlNameHelper.NameProperty);
}
public static void SetName(DependencyObject d, string val)
{
d.SetValue(UserControlNameHelper.NameProperty, val);
}
public static readonly DependencyProperty NameProperty =
DependencyProperty.RegisterAttached("Name",
typeof(string),
typeof(UserControlNameHelper),
new FrameworkPropertyMetadata("",
FrameworkPropertyMetadataOptions.None,
(d, e) =>
{
if (!string.IsNullOrEmpty((string)e.NewValue))
{
string[] names = e.NewValue.ToString().Split(new char[] { ',' });
if (d is FrameworkElement)
{
((FrameworkElement)d).Name = names[0];
Type t = Type.GetType(names[1]);
if (t == null)
return;
var parent = FindVisualParent(d, t);
if (parent == null)
return;
var p = parent.GetType().GetProperty(names[0], BindingFlags.Instance | BindingFlags.Public | BindingFlags.SetProperty);
p.SetValue(parent, d, null);
}
}
}));
public static DependencyObject FindVisualParent(DependencyObject child, Type t)
{
// get parent item
DependencyObject parentObject = VisualTreeHelper.GetParent(child);
// we’ve reached the end of the tree
if (parentObject == null)
{
var p = ((FrameworkElement)child).Parent;
if (p == null)
return null;
parentObject = p;
}
// check if the parent matches the type we’re looking for
DependencyObject parent = parentObject.GetType() == t ? parentObject : null;
if (parent != null)
{
return parent;
}
else
{
// use recursion to proceed with next level
return FindVisualParent(parentObject, t);
}
}
}
}
y su ventana o código de control subyacente establece que controla por propiedad:
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
public Button BtnOK { get; set; }
}
tu ventana xaml:
<Window x:Class="user_Control_Name.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:test="clr-namespace:user_Control_Name"
xmlns:helper="clr-namespace:UI.Helpers" x:Name="mainWindow"
Title="MainWindow" Height="350" Width="525">
<Grid>
<test:TestUserControl>
<Button helper:UserControlNameHelper.Name="BtnOK,user_Control_Name.MainWindow"/>
</test:TestUserControl>
<TextBlock Text="{Binding ElementName=mainWindow,Path=BtnOK.Name}"/>
</Grid>
</Window>
UserControlNameHelper obtiene su nombre de control y su nombre de clase para establecer Control en Propiedad.
