Creating a user interface user interface element in WPF

Question

I have several TextBoxess Labelsin my code that are implemented with the following XAML:

<DockPanel HorizontalAlignment="Right">
    <TextBlock Foreground="Black" Padding="0,0,10,0">Serial Number:</TextBlock>
    <TextBox Width="150" IsReadOnly="True" BorderBrush="Gainsboro" Height="20"></TextBox>
</DockPanel>

I can reduce the portion of the copied code by doing something like:

<DockPanel HorizontalAlignment="Right">
    <TextBlock Style="{StaticResource CstmTextBoxLbl}">Serial Number:</TextBlock>
    <TextBox Style="{StaticResource CstmTextBox}"></TextBox>
</DockPanel>

but it is still somewhat long. Is it possible to do something like:

<controls:CstmTextBox Style="{StaticResource CstmTextBox}" LabelText="Serial Number:" Text=""/>

Where CstmTextBoxwill I implement any XAML needed to get the same visual effect once, and I could access the text TextBlockand tag TextBoxin the code. For instance,

CstmTextBox textbox;
textbox.LabelText = "Serial Number:";
String some_text = textbox.Text;

textbox.Text = "....";

UserControl or CustomControl serves your needs. This is the code for CustomControl.

WITH#:

public class CstmTextBox : Control
{
    public string LabelText
    {
        get
        {
            return (string)GetValue (LabelTextProperty);
        }
        set
        {
            SetValue (LabelTextProperty, value);
        }
    }

    public static readonly DependencyProperty LabelTextProperty =
        DependencyProperty.Register ("LabelText", typeof (string), typeof (CstmTextBox), new PropertyMetadata (string.Empty));

    public string Text
    {
        get
        {
            return (string)GetValue (TextProperty);
        }
        set
        {
            SetValue (TextProperty, value);
        }
    }

    public static readonly DependencyProperty TextProperty =
        DependencyProperty.Register ("Text", typeof (string), typeof (CstmTextBox), new PropertyMetadata (string.Empty));
}

XAML:

    <Style TargetType="{x:Type controls:CstmTextBox}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type controls:CstmTextBox}">
                    <DockPanel HorizontalAlignment="Right">
                        <TextBlock Foreground="Black" Padding="0,0,10,0" Text="{TemplateBinding LabelText}"/>
                        <TextBox Width="150" IsReadOnly="True" BorderBrush="Gainsboro" Height="20" Text="{TemplateBinding Text}"/>
                    </DockPanel>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Add a style to your resources and use the new control:

    <controls:CstmTextBox LabelText="abcde" Text="1234"/>

UserControl XAML, .

x:Name UserControl...

<UserControl ... >
    <DockPanel HorizontalAlignment="Right">
        <TextBlock x:Name="SerialNumberTextBlock" Style="{StaticResource CstmTextBoxLbl}">Serial Number:</TextBlock>
        <TextBox x:Name="SerialNumberTextBox" Style="{StaticResource CstmTextBox}"></TextBox>
    </DockPanel>
</UserControl>

... ( ) :

CstmTextBox textbox;
textbox.SerialNumberTextBlock.Text = "Serial Number:";
String some_text = textbox.SerialNumberTextBox.Text;

textbox.SerialNumberTextBox.Text = "....";

, DependencyProperties , . UserControl:

public string Text
{
    get
    {
        return (string)GetValue(TextProperty);
    }
    set
    {
        SetValue (TextProperty, value);
    }
}

public static readonly DependencyProperty TextProperty = 
    DependencyProperty.Register("Text", typeof(string), typeof (CstmTextBox));

UserControl:

<UserControl x:Name="Root" ... >
    <DockPanel HorizontalAlignment="Right">
        <TextBlock x:Name="SerialNumberTextBlock" Style="{StaticResource CstmTextBoxLbl}"
                   Text="{Binding LabelText, ElementName=Root}" />
        <TextBox x:Name="SerialNumberTextBox" Style="{StaticResource CstmTextBox}"
                 Text="{Binding Text, ElementName=Root, Mode=TwoWay}" />
    </DockPanel>
</UserControl>
