You can also bind in the XAML, if the objects you want to bind to are public and are properties of the object in your data context:

<Window x:Class="CarSystem.AlarmsDialog"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        DataContext="{Binding MyDataContextObject, RelativeSource={RelativeSource Self}}"
        Title="LPR - Mobile Plate Hunter 900: Alarms">

    <Grid>
        <TextBox Text={Binding Path=MyTextProperty, Mode=TwoWay} />
    </Grid>
</Window>

Since you tagged WPF, consider doing this in XAML only:

<TextBox Text="{Binding Path=SomeTextProperty, Mode=TwoWay}" />

Bind like this:

TextBox MyText = new TextBox();

Binding binding = new Binding();
binding.Path = new PropertyPath("Name"); //Name of the property in Datacontext
BindingOperations.SetBinding(MyText,TextBox.TextProperty , binding);

If you want to bind to certain object which contains Name property you will have to set binding.Source to that object also.
