RadSpreadsheet: Drag selection behavior inconsistent

The UI behaivor of drag selection shows inconsistent behavior between WinForm vs WPF/Excel.

When you drag some cells for selection and keep dragging to the right (getting the out scope), the control scrolls to the right.

This behavior is common in Winform/WPF/Excel.

When you drag backward (to the left), WPF controls scroll back and so is Excel, while Winform controls does not scroll

Same thing for top and bottom scroll. Winform Spreadsheet control does not scroll. It may scrolls only to the right.

Another Caveat I see meanwhile is that when you scroll backwards until the row area, the pointer become row-resize pointer, or so

If you keep mouse moving around, it sometimes makes a horizontal line (possibly a guide for row resize?)

The issue in this case is that, it does not remove itself. the horizontal line stays there. It is not very annoying (as it is thin horizontal line) but is still a bug.

 

To reproduce,

create a empty Winform app, with the RadSpreadsheet Control, and Run

Drag from row C3 and to the right (around the scrollbar) the control scrolls to the right (this is not quite smooth though..)

Scroll right to AZ3 say, and drag backward back to C3, this now does not scroll back.

Same for top and bottom.

Do the same for WPF, it now works as expected

Do the same for MS Excel, it now works as expected.

Hello, Junsoo,

The provided detailed information is greatly appreciated. I was able to replicate the undesired behavior.

I have logged it in our feedback portal by making this thread public. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

 

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use the arrow keys to scroll in the desired direction.
