如何从背后的代码操纵扩展头

Question

I have this code in XAML:

  <Expander BorderBrush="DarkGray" Background="White" SourceUpdated="Expander_SourceUpdated" GotFocus="Expander_GotFocus">
                                                <Expander.Header>
                                                    <StackPanel Orientation="Horizontal">
                                                        <TextBlock Text="Grupo " VerticalAlignment ="Center"/>
                                                        <TextBlock x:Name="Tblockgrupo" Text="{Binding Name}" VerticalAlignment ="Center" GotFocus="TextBlock_GotFocus" />
                                                        <TextBlock Text="{Binding ItemCount}" VerticalAlignment ="Center"/>
                                                        <TextBlock Text=" Variable(s)" VerticalAlignment ="Center"/>
                                                    </StackPanel>
                                                </Expander.Header>
                                                <ItemsPresenter />
                                            </Expander>

My question is how capture the text of the TextBlock with name: Tblockgroup, from codebehind (c#) when the expander has focus.

I found the solution

object result = Prueba.FindName("name"); if (result is TextBlock) { // Following executed if Text element was found. TextBlock resultconvert = result as TextBlock; MessageBox.Show(resultconvert.Text); }
