DataGridView checkbox column “select all” performance?

Thanks a lot, by setting the AutoSizeColumnsMode property.

Well, this is a common problem. First, do you have any processing associated with the Checkbox checked change? If so, create a bool member variable.

Initialize it to false before performing the Select All / Deselect All. In the CheckBox checked change event -> check for the value of the bool paramter. If it comes with false return from the event.

Don't process anything. After completing the for looping to set the select all / Deselect All, process the checked change event if necessary. Don't forget to reset the bool parameter to true after for loop.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
