Selection behavior

[Vladimir Arkhipov]

Hi, I have 2 questions:

1. SelectionMode.One I press Esc button -> selection disappeared. Is it possible to have a persistent selection?

2. SelectionMode.One I press Delete button -> data disappeared from the whole row. Is it possible to make changes to current cell only?

1. One idea would be to handle KeyDown and KeyUp and set a flag if Escape is pressed and reset it in KeyUp. You can then handle the selectionChanging event and set e.Cancel = true if Escape was pressed.

2. Again handle KeyDown, KeyUp, set flag and then in ClearingCells set e.Handled = true.

Thank you (50%)
2. ClearingCells works!, I just added code like this:
if(e.RangeList.ActiveRange.IsRows)
{
e.Handled = true;
}

1. SelectionChanging event is not fired on Esc button press, selection just silently disappeared:(.

I will have to look into why SelectionChanging is not raised for Escape key. Will probably need to make some code changes in the grid sources for that.

But, try
a) set grid.WantEscapeKey = false
- or -
b) override OnKeyDown and CurrentCellKeyDown and check for Keys.Escape and don't call base class version and set e.Handled = true

Does that help?

There is though one problem with WantEscapeKey = false.

It works fine for standard text boxes, but if my cell have an image in it then "WantEscapeKey = false" resulted in blocking escape functionality.
So if I am in edit mode Esc press restores initial values for standard text box and do nothing for text box with ImageIndex >= 0.

Is it possible to fix it?

Can you handle the CurrentCellKeyDown event and add necessary code for what you want to with the Escape key? (e.g. call CurrentCell.RejectChanges)
