Update value based on text box "enter" key hit

Basically, I have a lot of text boxes that will be holding minimum and maximum values for a variable, I would like it so when I hit enter on one text box, it will "commit" the value (without losing focus of the box).

Is this possible?

These are the boxes that I am currently running (copy the format about 10 more times)

        <!-- Min -->
        <TextBox Name="Min_1" Text=""/>
        <TextBox Name="Min_1" Text=""/>
        <TextBox Name="Min_2" Text=""/>
        <TextBox Name="Min_3" Text=""/>
        <TextBox Name="Min_4" Text=""/>

        <!-- Value -->
        <TextBlock Name="vlu_1"/>
        <TextBlock Name="vlu_1"/>
        <TextBlock Name="vlu_2"/>
        <TextBlock Name="vlu_3"/>
        <TextBlock Name="vlu_4"/>

        <!-- Max -->
        <TextBox Name="txtMax_1" Text=""/>
        <TextBox Name="txtMax_1" Text=""/>
        <TextBox Name="txtMax_2" Text=""/>
        <TextBox Name="txtMax_3" Text=""/>
        <TextBox Name="txtMax_4" Text=""/>

Within my C# code, the vlu_# is updated every 5 seconds, but this shouldn't affect what I need.

So to break down, I need a way that once I hit the enter key, the value of vlu_1 etc will change straight away

Should be able to just use the KeyDown event on the textbox to trigger your 'commit' code when enter is pressed.

<TextBox Name="txtMin_1" Text="" Width="20" Margin="193,34,223,134" KeyDown="txtMin_1_KeyDown"/>

and then in code

private void txtMin_1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.Key == Key.Enter)
        {
            //commit code here
        }
    }
