When passed a collection of cell regions and the SelectionMode property is Extended, the SelectCellRegion method selects only the last cell region.

We could include this functionality in the event arguments of the CellDecorationsNeeded event, similarly to the way that the Foreground and Background properties are set. This way, the cells will have more customization options.

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.

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)

CopyToClipboard method of the virtual grid copies the last selected cell.

Setting/Binding SelectedIndex property does not change the selected item.

When the UI Filtering is disabled through the IsFilterable or CanUserFilterColumns property, the filtering button is hidden, however the mouse cursor is changed to Hand in its location and the columns cannot be filtered when clicking over it. 

When the user clicks on a cell, the whole row will be selected. However, if we clear the selected items by calling the UnselectAll method, clicking again on the same cell does not select the row.

In this case, when we call PushCellValue on a VirtualGrid that is still not loaded a NullReferenceException is thrown.

We can introduce the option for resizing the columns in code such as Winforms feature:  https://docs.telerik.com/devtools/winforms/controls/virtualgrid/columns/resizing-columns-programmatically

Currently the control has a FitColumnWidthToContent method. We can expose similar functionality for the rows. 

Adding Greater/LessThan filter operator results in an exception when using a DataProvider and a DataTable as its source

VirtualGridCellClipboardEventArgs.Cell.ColumnIndex is off by 1 if you pin a column to the left.

Same with VirtualGridCellClipboardEventArgs.Cell.RowIndex if you pin a column to the top.

 

• Option to get visible rows or cells or check if cell\ row is visible
• Will be great to have command SelectAllVisible in addition to SellectAll

Thanks,

The ArgumentOutOfRangeException is thrown when there are pinned columns, and DataProvider is changed.

Create a built-in method which exports the control in .xlsx format.

Only the first selected item is returned in the AddedItems argument of the SelectionChanged event when using the Extended selection mode.

Add ToolTip support for VirtualGrid.

Background and Foreground properties of HeaderCellDecorationsNeeded event args are not respected
