Can't retrieve the value of a DataGridView Checkbox

[Benysh]

Hi everyone.

I'm having a really annoying problem I can't solve and couldn't find an answer to anywhere, let's see if you got what it takes.

I have a dataGridView on a C# Windows Form. Unbound. I fill in rows with a button.

I have a checkbox column which isn't read-only (unlike the other columns) so the user could check whatever row he wants.

All I simply want is to know (on CellContentClick) if the checkbox is checked or not!

I do this for now:

private void dataGridView1_CellContentClick(object sender,DataGridViewCellEventArgs e)
     {
MessageBox.Show(dataGridView1[e.ColumnIndex, e.RowIndex].Value.ToString());
}

It works for every other cell, but when clicking a checkbox, it fails and returns:
"Object reference not set to an instance of an object."
Why? Because the .Value = null.

Please please help!

Thanks alot in advance,
Ben.

OK!

Just managed pulling it off myself:

MessageBox.Show(dataGridView1[e.ColumnIndex, e.RowIndex].EditedFormattedValue.ToString());

Probably had something to do with if it's in Edit mode or not

Thanks alot! This forum is awesome!

heh

thanks

though now I have something I didn't manage ;)

EditedFormattedValue seems to be readonly

How do I change the checkbox status? For example, on a button click, check/uncheck a certain checkbox cell

Well?

Thanksa
