Usually, you can set the AutomationId of a FrameworkElement using the AutomationProperties.AutomationId attached property. However, because of the specific implementation of RadVirtualGrid, there are no separate visual elements per row or cell, so you cannot use the approach with the attached property. But, there are custom automation peers for the cells which can be customized. Add an API that allows you to set the AutomationId of the cells when the peer (VirtualGridCellInfoAutomationPeer) or the cell info is created.

Release LIB 2021.3.1213 (13 Dec 2021)

I have an application that uses docking. Each pane contain a virtual grid.

If the user toggles between panes, any future font size changes are not reflected by the virtual grid

I have attached a demo project that shows the problem.

 

After launching the application:

1) click the Increase/Decrease Font buttons to see the font size change.

2) click tab2 then go back to tab1

3) click the Increase/Decrease Font buttons to see the Virtual Grids font size no longer updates.

 

(I have a third virtual grid outside of the Docking that shows that the font does change if not used inside of a docking control)

Release LIB 2019.3.1007

I believe this is caused a bug in Telerik.Windows.Controls.VirtualGrid.Selection.CellSelectionHandler.ToggleSingleSelect() method:

    internal void ToggleSingleSelect()
    {
      if (this.owner.SelectionUnit != VirtualGridSelectionUnit.Cell && this.SelectedCells.Count <= 1)
        return;
      this.BeginSelection();
      VirtualGridCellInfo selectedCell = this.SelectedCells[0];
      this.DeselectAll();
      this.Select(selectedCell);
      this.EndSelection();
    }

If SelectionUnit = Cell but no cells are selected, the code still attempts to retrieve the first selected cell what causes an exception. 

 

Stack trace:

System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
