如何检查datagridview是否为空？

Question

I already tried this way but it is not working.

How do I fix it?

     if(dgvProducts.Rows.Count < 1 )
     {
         MessageBox.Show("Something");
         return;
     }

you may try something like this,

if(dgvProducts.Rows.Count > 1 )
 {
     MessageBox.Show("Something");
     return;
}

if it doesn't works then you may also try something like this too,

string nrCode = dataGridView1.Rows[0].Cells[6].Value.ToString();
nrCode = nrCode.Trim();
if (nrCode == string.Empty)
{
MessageBox.Show("there must be Entry in cell nrCode on first row.")
}

the above code will allow you to check if specific cell in first row in DataGridView is empty.

Hope it works.
