I'm having problem in creating a delete confirmation message box in the DataGrid. For your information, i need the process to be in this way,

display records --> press delete button --> delete confirm message box--> record deleted

Suppose that when the user press the delete button, a delete confirm message box should pop out to verify the deletion with the user, but it doesn't.

Moreover, i failed to create my own one. Is it there any way to create such a delete confirmation message box in DataGrid?
