  Hello Component One Team,

  I have a query regarding expanding/collapsing of a group in C1DataGrid.

  In attached image (Grid.PNG), we want to handle click event for expand (+) and collapsed (-) for group.

  Could you please provide us inputs on how we can get this event handler.

  Thank you,
  
  Swapnil Walwadkar

  Hi,

  Thanks for reaching out to us with your query.
  
  You can achieve this requirement by handling GroupRowsVisibilityChanged event for all GroupRows as:

  var grpRows = grid.Rows.Where(x => x.GetType() == typeof(DataGridGroupRow)).ToList();
  foreach (DataGridGroupRow grpRow in grpRows)
  {
      grpRow.GroupRowsVisibilityChanged += (s1, e1) =>
      {
          Debug.WriteLine("Group Row: " + (s1 as DataGridGroupRow).GetGroupText() + " is " + e1.NewValue.ToString());
      };
  }

  Please refer the attached sample for the same: DataGridGroup.zip

  Best Regards,
