XAML link to section of window - wpf

Question

In XAML how can I set a hyperlink to take the user to a particular section of my window. Like how you can with anchor tags in HTML. Basically we want the user to be able to click on an error in a list of errors and the link will take them to that area.

Answer 1

XAML Hyperlink NavigateUri could work with a bit of code behind, i.e.
<Window x:Class="fwAnchorInWindow.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel>
<TextBox x:Name="TextBoxName" Text="Enter Name"/>
<TextBox x:Name="TextBoxNumber" Text="Enter Number"/>
<TextBlock>
<Hyperlink NavigateUri="TextBoxName" RequestNavigate="Hyperlink_RequestNavigate">
There is a name error.
</Hyperlink>
</TextBlock>
</StackPanel>
</Window>
using System.Windows;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Navigation;
namespace fwAnchorInWindow
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
if (sender is Hyperlink)
{
string controlName = ((Hyperlink)sender).NavigateUri.ToString();
IInputElement control = (IInputElement)this.FindName(controlName);
Keyboard.Focus(control);
}
}
}
}
FindName is only one way to find a child control. There are also other ways per this post: WPF ways to find controls.
It is also important to note that WPF distinguishes between Logical Focus and Keybaord Focus: Mark Smith's It's Bascially Focus. In the code above having keyboard focus automatically indicates logical focus.
