Question

I want to save the data from datagrid to database, I used the following code.

 foreach (DataGridViewRow r in dataGridView_displaycount.Rows)
        {
            SqlCommand cmd = new SqlCommand("insert into StocktransferlocationDetails(date,stocktransferlocation,Itemcode,Count,Description) values(@date,@stocktransferlocation,@Itemcode,@Count,@Description) ", con);

            cmd.Parameters.AddWithValue("@date",System.DateTime.Now);
            cmd.Parameters.AddWithValue("@stocktransferlocation", comboBox_locationfrom.SelectedText+"-"+comboBox_locationto.SelectedText);
            cmd.Parameters.AddWithValue("@Itemcode", r.Cells[1].Value.ToString());
            cmd.Parameters.AddWithValue("@Count", r.Cells[2].Value.ToString());
            cmd.Parameters.AddWithValue("@Description", r.Cells[3].Value.ToString());
            cmd.ExecuteNonQuery();
        }

Here my problem is the datagrid contains the empty row at the last. So I write the data and when it comes to the empty row it throws me an error.

Why use a foreach loop here?

Use a for loop like:

for(int i=0; i<dataGridView_displaycount.Rows.Count-1; i++)
{
   //Your code
}

This should be an easy solution to solve your problem rather than any other code changes.

Update: Adding the gridview data to the database:

for(int i=0; i< dataGridView_displaycount.Rows.Count-1;i++)
 {
    Strquery= @"Insert into StocktransferlocationDetails(date,stocktransferlocation,....) values (" 
                + System.DateTime.Now +", "+ comboBox_locationfrom.SelectedText+"-"+comboBox_locationto.SelectedText +"," 
                + dataGridView_displaycount.Rows[i].Cells[1].Value +".......);";
    cmd.CommandText = Strquery;
    cmd.ExecuteNonQuery();
 }
