Scrollviewer to a postion of a control by code

I am developing a small application when i need to scroll by code to a postion of a GroupBox Control, the part of my xaml files that contains the scrollviewer is the following one (I have a scrollviewer, inside a stackpanel and inside of that the GroupBox):

<ScrollViewer x:Name="scrollViewer" Grid.Row="1" HorizontalScrollBarVisibility="Disabled" VerticalScrollBarVisibility="Visible">
    <StackPanel x:Name="stackPanel" VerticalAlignment="Stretch" Margin="0,16,0,0">
        <GroupBox x:Name="groupBox">

                <TextBlock Text="Desbloquear" FontWeight="Bold"/>
            </GroupBox.Header>

    </StackPanel>
</ScrollViewer>

I have tried other solutions in stackoverflow but i can't figure out why i can not handled it to work.

I just have the declaration of the function

private void ScrollToGroupBox(System.Windows.Controls.GroupBox groupBox)
{
    //I NEED TO GET THE POSITION OF THE GRUOPBOX INSIDE OF THE SCROLLVIEWER
    scrollViewer.ScrollToVerticalOffset(0);
}

CodePudding user response：

private void ScrollToGroupBox(System.Windows.Controls.GroupBox groupBox)
{
    groupBox.BringIntoView();
}
