GridCtrl::Reset does not reset. [message #25703]

Hi,

It would be good to have a GridCtrl function which completely reset the control (not necessarily the settings but certainly the columns and data). When I add a bunch of columns and then Reset and add them again then the display gets messed up. I've also tried GridCtrl::Clear(true) and that doesn't appear to work either.

Basically I want to be able to add a bunch of columns and data and then update the data and do it all again.

Hello nixnixnix

I use usually Clear(true) and it cleans data and columns.

Could you pass a working code sample about it ?

Best regards
Iñaki

Reset works fine. I wrote about this column problem many times here (this means I have to redesign it as it's not intuitive Smile

).
Just put all your AddColumns between following method calls:

grid.Ready(false);
grid.AddColumn(...);
grid.AddColumn(...);
grid.Ready(true);

This display mess happens only in proportional mode and only if grid is visible on the screen. It is so because each AddColumn recalculates columns proportions being not aware of next AddColumn calls. I'll put this issue on my todo list.
