Because it's broken.

For more specific help, ask a more specific question, which probably means posting some code, as well as telling us what *does* happen ( does the form run at all ? does it crash ? )

int rowNumber = 3;<br />
            int cellNumber = 2;<br />
<br />
            bool b = (bool)dataGridView1.Rows[rowNumber].Cells[cellNumber].Value;

But one tricky thing is here: if a value you are getting was not set (nobody checks or unchecks this checkbox) the value of it is null. We need handle this case.

            int rowNumber = 3;<br />
            int cellNumber = 2;<br />
<br />
            bool b = false;<br />
            if (dataGridView1.Rows[rowNumber].Cells[cellNumber].Value != null)<br />
            {<br />
                b = (bool)dataGridView1.Rows[rowNumber].Cells[cellNumber].Value;<br />
            }<br />

You want to see if the user has a file on the local machine from an ASP web page? Can't do it, you don't have file access rights to the local machine from a web page.

ActiveX has file rights I think. Not sure, why do you need to do this from a web application.

I wouldn't thank me yet, make sure it does what you need it to. I still don't understand why you are doing that check.
