How to open DataGridHyperlinkColumn Links in the default browser by event?

[TheophilusE]

I have the following layout but trying to open the link from the application by clicking on the column item causes the link to open in the application itself, instead of the default browser.

Snippet of my setup

<Grid Grid.Row="1">
      <Grid.ColumnDefinitions>
          <ColumnDefinition Width="*" />
      </Grid.ColumnDefinitions>
  
      <DataGrid
          Margin="0,20,0,0"
          IsReadOnly="True"
      
          CanUserAddRows="False"
          CanUserSortColumns="True"
          CanUserDeleteRows="False"
          CanUserResizeRows="False"
          CanUserResizeColumns="True"
          CanUserReorderColumns="False"
          
          AutoGenerateColumns="False"
      
          ItemsSource="{Binding ViewModel.DataGridItemCollection}">
          <DataGrid.Columns>

                  <DataGridHyperlinkColumn
                        Header="URL"
                        Binding="{Binding URLID}"
                        ContentBinding="{Binding URLID}"
                        MinWidth="25"
                        Width="*" />

          </DataGrid.Columns>
                
     </DataGrid>
</Grid>

For testing purposes, I have bound the data to https://google.com and here is the result.

From research done, one should be able to assign an hyperlink click event but this does not work with the current setup. See https://stackoverflow.com/questions/2474801/wpf-datagrid-datagridhyperlinkcolumn-bound-to-uri. Is there something I am missing or is this not supported? If it is not supported, how may I achieve such functionality, thanks.

Deduced a workaround for this using the DataHyperlinkColumn. The workaround ensures that the hyperlink RequestNavigate event is handled to prevent the application navigating to it using the in-built web view. My setup is stated below.

<Grid Grid.Row="1">
      <Grid.ColumnDefinitions>
          <ColumnDefinition Width="*" />
      </Grid.ColumnDefinitions>
  
      <DataGrid
          Margin="0,20,0,0"
          IsReadOnly="True"
      
          CanUserAddRows="False"
          CanUserSortColumns="True"
          CanUserDeleteRows="False"
          CanUserResizeRows="False"
          CanUserResizeColumns="True"
          CanUserReorderColumns="False"
          
          AutoGenerateColumns="False"
      
          ItemsSource="{Binding ViewModel.DataGridItemCollection}">
          <DataGrid.Columns>

                  <DataGridHyperlinkColumn Header="URL" Binding="{Binding APIURLID.Uri}" ContentBinding="{Binding APIURLID.Content}" Width="55" >
                        <DataGridHyperlinkColumn.ElementStyle>
                            <Style TargetType="TextBlock">
                                <EventSetter Event="Hyperlink.RequestNavigate" Handler="OnApiUriClicked"/>
                            </Style>
                        </DataGridHyperlinkColumn.ElementStyle>
                    </DataGridHyperlinkColumn>

          </DataGrid.Columns>
                
     </DataGrid>
</Grid>

To ensure that the application does not try to open the link also, one has to mark the event as handled after opening the URI in the default web browser.

private void OnApiUriClicked(object sender, RoutedEventArgs e)
{
    if (((System.Windows.Documents.Hyperlink)e.OriginalSource).DataContext is not ProductDescriptor rowData)
    {
        return;
    }
    try
    {
        Debug.WriteLine("Opening url in default web browser. {0}", rowData);

        /// Other code
    }
    catch (Exception exception)
    {
        Debug.WriteLine("Encountered an exception opening Uri. {0}", exception.Message);
    }
    e.Handled = true;
}
