Hello ,

I think one of the Datagridview property AllowUserToAddRows is True . Hence when you add rows in your datagridview , a blank row added . Now , when you save the datagridview in your database , the last row obviously null .

I suggest you to write a For loop instead of Foreach . like this way ..

for(int i=0;i<datagridview1.Rows.Count-1 ; i++ )
{
//others stuffs .....

}

thanks
