Expanding or Collapsing all Groups

[Peter]

HI All,

Is it possible to Expand and or Collapse all the grouped items in a WPF Card View. 

 I have grouped them like so

cardView.GroupCards("Name");

and would like to Collapse them all initally

regards

Peter

Hi Peter,

Currently, we have no support to collapse and expand the groups programmatically, however, you can achieve your requirement by accessing the expander control of the Cardview using a visual tree and changing its IsExpanded property.

Code Snippets:

private void FindExpanders(DependencyObject parent)
{
    int count = VisualTreeHelper.GetChildrenCount(parent);
    for (int i = 0; i < count; i++)
    {
          var child = VisualTreeHelper.GetChild(parent, i);
          if (child is Expander expander)
          {
                expander.IsExpanded = false;
          }
          else
          {
               FindExpanders(child);
           }
     }
}

We have created a simple sample based on your requirement. Please refer to the sample for your reference.

Regards,
