Question: I created a user control in WPF:

```
<UserControl x:Class="TestUserControl.Controls.GetLatest"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
        <TextBlock Name="theTextBlock"/>
</UserControl>

```

The code behind has a parameter called "FirstMessage" which it sets as the text of my user control TextBlock:

```
public partial class GetLatest : UserControl
{
    public string FirstMessage { get; set; }

    public GetLatest()
    {
        InitializeComponent();
        theTextBlock.Text = this.FirstMessage;
    }
}

```

In my main code I can set the FirstMessage parameter in my user control with intellisense:

```
<Window x:Class="TestUserControl.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="300" Width="300"
    xmlns:controls="clr-namespace:TestUserControl.Controls"
    >
    <StackPanel>
        <controls:GetLatest FirstMessage="This is the title"/>
    </StackPanel>
</Window>

```

However, it still doesn't set the text. I've tried Text="{Binding Path=FirstMessage}" and other syntaxes I have found but nothing works.

How can I access the FirstMessage value in my user control?

Answer: 
This quick example won't use any binding because the value isn't set up until after the Default Constructor is called, but here's how you can get the text to show up.

```
<UserControl x:Class="TestUserControl.Controls.GetLatest"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Loaded="GetLatest_Loaded">
        <TextBlock Name="theTextBlock"/>
</UserControl>

```

Then, just modify your cs file to this:

```
public partial class GetLatest : UserControl
{
    public string FirstMessage { get; set; }

    public GetLatest()
    {
        InitializeComponent();
        theTextBlock.Text = this.FirstMessage;
    }

    private void GetLatest_Loaded(object sender, RoutedEventArgs e)
    {
        theTextBlock.Text = this.FirstMessage;
    }
}

```

I recommend working on setting up a Binding instead, as this is fairly spaghetti-like code.
In the case of the code you posted above it is a timing issue; the FirstMessage property has not had its value assigned when the constructor executes. You'd have to execute that code in an event occuring later on such as Loaded.
