Parsing the identify fields

DonFreeman

I seem to have lost my original post on this subject. My layer contains a field with a web address that I would like to appear as a hyperlink when the results are shown in an identify datagrid. Given the layer is selected via the code below (taken from the identify sample) how can I parse the datagrid and assign a hyperlink to the field containing an HTTP address?

 Private Sub cb_SelectionChanged(ByVal sender As Object, ByVal e As SelectionChangedEventArgs)
  Dim index As Integer = IdentifyComboBox.SelectedIndex
  If index > -1 Then
   IdentifyDetailsDataGrid.ItemsSource = _dataItems(index).Data
  End If
 End Sub

Thanks

I was finally able to selectively create hyperlinks in the identify results.

You need to add an event handler to your results datagrid for LoadingRow in your xaml file.  The event handler is where I check for a field name and determine whether or not it's a known hyperlink field.  I use a helper function to get the current contents of the cell and swap them out with my hyperlink.

Not sure if it's the best approach, but it's working great in my app.

/// <summary>
/// Handles links in id results
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void IdentifyDetailsDataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            KeyValuePair<string, object> pair = (KeyValuePair<string, object>)e.Row.DataContext;
            if (pair.Key == FLD_PCN)
            {
                DataGridColumn column = this.IdentifyDetailsDataGrid.Columns[1];
                FrameworkElement fe = column.GetCellContent(e.Row);
                FrameworkElement result = GetParent(fe, typeof(DataGridCell));
                if (result != null)
                {
                    DataGridCell cell = (DataGridCell)result;
                    TextBlock txt = new TextBlock() { Text = pair.Value.ToString(), TextDecorations = TextDecorations.Underline };
                    HyperlinkButton hyperlink = (HyperlinkButton)cell.Content;
                    hyperlink.Content = txt;
                    hyperlink.Foreground = new SolidColorBrush(Colors.Blue);
                    string strUri = LINK_PAPA + pair.Value.ToString();
                    Uri lnkUri = new Uri(strUri);
                    hyperlink.NavigateUri = lnkUri;
                    hyperlink.IsHitTestVisible = true;
                }
            }
.....else if blah blah blah
}

/// <summary>
        /// Helper function used to get individual cell contents
        /// </summary>
        /// <param name="child"></param>
        /// <param name="targetType"></param>
        /// <returns></returns>
        private FrameworkElement GetParent(FrameworkElement child, Type targetType)
        {
            object parent = child.Parent;
            if (parent != null)
            {
                if (parent.GetType() == targetType)
                {
                    return (FrameworkElement)parent;
                }
                else
                {
                    return GetParent((FrameworkElement)parent, targetType);
                }
            }
            return null;
        }
