If you are using MVVM pattern, You have to create the following command on your ViewModel that copy the content of your TextBox:

public ICommand CopyValueCommand
        {
            get
            {
                return new CommandHandler(

                    () => 
                         // Here your Text box should bind a property of your model
                         // Copy your model property value to ClipBoard
                         Clipboard.SetText(this.SelectedElement.YourProperty));
            }
        }

Then on XAML, use System.Windows.Interactivity to invoke your command when your DataGrid Selection is changed:

<DataGrid ItemsSource="{Binding Path=Elements, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                  SelectedItem="{Binding Path=SelectedElement, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                  >
            <i:Interaction.Triggers>
                <i:EventTrigger EventName="SelectionChanged">
                    <i:InvokeCommandAction Command="{Binding Path=CopyValueCommand}"/>
                </i:EventTrigger>
            </i:Interaction.Triggers>
                ...
            </DataGrid.Columns>
        </DataGrid>

Remark

• I supposed that your TextBox text binding a property of your model.

• Note that you need to reference System.Windows.Interactivity.dll to your project. I hope this helps you!
