Why is it so difficult to format the code properly?
The easier to read the more answers you will get.
I did it for you this time.

How would you expect the user to select Yes and No from your messagebox to begin with?

add an else block after
'if (dr == DialogResult.Yes) {}'
set the checkbox cells value to Falsevalue

also change the heading of the question to ur requirement

Seconded! george, you should put this as a solution

george4986 15-Sep-14 3:29am

what u mean by seconded? its a suggestion not a solution(his coding not checked ) also the question header is not correct

Sinisa Hajnal 15-Sep-14 5:21am

I mean I agree with your suggestion and that you should put that in a solution field. I would suggest the same thing so instead of writing it (again) I seconded yours along with suggestion to you to write it as a solution.

you need to add else block for don't delete

C#

if (dr == DialogResult.No)
   {            foreach (DataRow row in ((DataTable)dataGridView1.DataSource).Rows)
            {
                if (row[0].ToString().ToLower()=="true".ToLower())
                   row[0]=false;
            }
    }
