The expanded state of the hierarchical item is not preserved when searching thought search panel for something that is not found and clearing search text.

When you define a style targeted at GridViewCell with a color without transparency, horizontal grid lines are hidden.

Currently search tries to match the search value to the complex object value, which always provides negative results. Adding such property will enable search over a primitive type, or string property of the given object.

If you set BorderThickness through a custom CellStyle, the left border is overwritten by our code. 

Full error message: No generic method 'Sum' on type 'System.Linq.Enumerable' is compatible with the supplied type arguments and arguments. No type arguments should be provided if the method is non-generic."

Showing in design time, working at run time. 

Placing text in quotes after exclude search operator and search getting the wrong result. As a workaround to get the desired result the search string can be changed in this way: from  -"Rio de" to  -Rio + -de.

Available in LIB version 2016.3.1128, it will be also available in the 2017 R1 Release.

To work this around set the GroupRenderMode property of RadGridView to Flat.

When GroupRenderMode is set to Nested the issue can be overcome by calling the BringIntoView method on the row returned in the ScrollIntoViewAsync method's callback:  
gridView.ScrollIndexIntoViewAsync(index,
  new Action<FrameworkElement>((f) =>
  {
      f.BringIntoView();
  }));
