Can you provide more details,
1) is CheckBox Column or datagridviewis ReadOnly ?
2) Is CurrentCellDirtyStateChanged event fired on first click ?

Hi rkhema,

Before I can locate the problem, I want to know some detail information about it.
Do you use databinding? If you use databinding, does that column a bool column in DataSource table?

Also please check whether that column has been set to ReadOnly?
