Tab behavior

[Gene Gorokhovsky]

How can I achieve the following tab behavior:
1) Pressing tab inside the grid activates next enabled cell even if is on the next row
2) pressing tab on the right-most bottom cell moves focus outside the grid

See model.Options.WrapCellBehavior.

You should set it to GridWrapCellBehavior.NextControlInForm

Unfortunately this setting seems to be broken in my version (1.6.1.6). After debugging grid source, it looks like grid sometimes cannot find the next/previous tab-enabled control. In our application grid is embedded in a panel, which is embedded in another panel which is embedded in the form. Previous and next tab-enabled controls are also enabled in (different) panels. We traced the offending code to method
bool Move(GridDirectionType direction, int num, bool extendSelection, bool wrapCell) in GridControlBase. Their there are two calls to f.SelectNextControl. The third parameter in the code is set to false, meaning that the .Net will not lookup tab-enabled nested controls on the form. It should be set to true, then the grid transfers the focus correctly.

We, of course, meant that the 4-th parameter to f.SelectNextControl is incorrect, not the third.

The Options.WrapCellBehavior works properly for grids directly on a form. But for grids parented to other containers like groupboxes, panels, usercontrols, ????, you have to do a little extra work. Take a look at this thread.

Item #3 there discusses this problem and has a sample that works for panels.

This "bug by design" should either be fixed or highlighted in documentation for WrapCellBehavior.
