Edit and Delete button inside a DataGridView

[eihabisaac]

dear all

i have a datagrid and i want to add a button,, when i click that button i delete a row from mysql database or when i click the edit button it calls another form based on Primary key which will be stored in one of the cells.

how to get to the event handler for that button inside a datagridview.

Thanks in advance
