I have a TGrid tied to a DataSet with 4 columns (with ControlTypes: ct Edit (x2),  ctCheckBox,  ctMultiLineEdit).

I am trying to add an OnRowChanged' Event to the grid.  My OnRowChanged Event will fire correctly for the ctEdit and ctMultiLineEdit, but not for the ctCheckBox.  I realize I need to double-click to change the value of the ctCheckBox and a single click will put the focus inside the box (but without firing the OnRowChanged Event).

Is there a way to tie the OnRowChanged Event to fire on the ctCheckBox ControlType?
 

Thanks
Nathan

Hmmm, I'm not seeing that behavior here (2.06 beta candidate) - a double-click definitely triggers the OnRowChanged event.  There's been one change to the dataset events, but it won't affect this issue.

I'll have to check this out with a proper 2.05 and see if I can replicate it there.

Tim.. you can drop (forget) this for now. I re-tried this on a very simple project and the event fires, even when navigating the 'check box' column. It is possible that something else is intercepting it, so we'll look into that.

thanks.. Bruno (for Nathan)

Tim..

Nathan did some quick testing (using EWB 2.05b3). It turns out that if you set the 'AlwaysShowControls' property (of the grid) to 'true'.. then the 'row change' does not fire when navigating rows on a 'checkbox' column. We also note that navigating the grid is quite sluggish if this property is set to true, but very fast otherwise. Finally, not sure what this property does.. as the 'checkboxes' are already visible 'always' anyway! So, from our point of view, 'problem fixed', we just set this property to 'false'.

thanks.. Bruno

Cool, thanks. I'll check this out further.  There is already an incident/fix for something similar, so this may be the same issue:
