如何获取usercontrol的TextBox内部的所有属性

Question

I created a UserControl in c# wpf. I want to get all properties of TextBox (txtCode) Property Box

<UserControl x:Class="WpfApplication2.UserControl1"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" Height="315.358" Width="758">
    <Grid >
        <TextBox x:Name="txtCode" HorizontalAlignment="Left" Height="97" Margin="134,62,0,0" TextWrapping="Wrap" Text="00001" VerticalAlignment="Top" Width="588" FontSize="30"/>
        <Label Content="Code" HorizontalAlignment="Left" Margin="27,72,0,0" VerticalAlignment="Top" Width="138" Height="97" FontSize="30"/>
        <Button Content="Submit" HorizontalAlignment="Left" Margin="290,186,0,0" VerticalAlignment="Top" Width="247" Height="48" FontSize="30"/>
    </Grid>
</UserControl>

In Windows form something Like below Image

c# Code

  public TextBox txtCodeProperties { get { return txtCode; } set { txtCode = value; } }

If you want to expose the whole TextBox and all of it's properties, you should look into x:FieldModifier . If you only need to expose some of the properties, you could expose them as DependencyProperties, as shown here .

How to use the FieldModifier:

In your UserControl1 , add the x:FieldModifier="public" attribute to your TextBox:

<TextBox x:Name="txtCode" x:FieldModifier="public" HorizontalAlignment="Left" Height="97" Margin="134,62,0,0" TextWrapping="Wrap" Text="00001" VerticalAlignment="Top" Width="588" FontSize="30"/>

Then, whenever you use UserControl1 , you now have public access to the textbox.

Example usage (xaml):

<local:UserControl1 x:Name="myUserControl1" />

Code-behind:

myUserControl1.txtCode.Text = "Hello, World!";
