  Hello,
  
  I am using C1 DataGrid in my WPF project.

  I have implemented hierarchical DataGrid using RowDetailsTemplate. I would like to know how we can access Child Datagrid from code behind. (I am trying to Expand/Collapse both Parent Grid and Child Grid on a single button click)

  Hello,

  For that you need to access the child grid using datagrid.Rows[rowIndex].DetailPresenter.Content and then set the child grid’s DetailsVisibility property to Visible/Collapsed for Expand/Collapse respectively, as follows:

  if (gridCategories.Rows[0].DetailsPresenter !=null)
  {
         var childGrd = gridCategories.Rows[0].DetailsPresenter.Content as C1.WPF.DataGrid.C1DataGrid;
         if (flagCollapse)
         {
               flagCollapse = false;
               childGrd.Rows[2].DetailsVisibility = Visibility.Collapsed;
         }
         else
         {
              flagCollapse = true;
              childGrd.Rows[2].DetailsVisibility = Visibility.Visible;
         }
  }
  
  

  Please refer attached sample application.
  
  Thanks,
