how to go next row in datagridview

Hi Mohammadali,


You can do it by using dataGrid as...

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.OleDb;
namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
    string ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["dsn"];
    OleDbCommand com;
    OleDbDataAdapter oledbda;
    DataSet ds;
    DataTable dt;
    String str;

        public Form1()
        {
            InitializeComponent();
        }

        private void btn_next_Click(object sender, EventArgs e)
        {
            dataGrid1.UnSelect(dataGrid1.CurrentRowIndex);
            dataGrid1.CurrentRowIndex += 1;
            dataGrid1.Select(dataGrid1.CurrentRowIndex);
        }

        private void Form1_Load(object sender, EventArgs e)
        {
          
            OleDbConnection con = new OleDbConnection(ConnectionString);
            con.Open();
            str = "select * from student";
            com = new OleDbCommand(str, con);
            oledbda = new OleDbDataAdapter(com);
            ds = new DataSet();
            oledbda.Fill(ds, "student");
            con.Close();
            dt = ds.Tables["student"];
            dataGrid1.ReadOnly = true;
            dataGrid1.DataSource = ds;
            dataGrid1.DataMember = "student";
        }
    }
}


Thanks

Try this
//This code selects the next row in the datagrid view while also making sure that it is not
//The last row.

 if(grdQustion.CurrentRow.Index < grdQustion.Rows.Count)
{
grdQustion.Rows[grdQustion.CurrentRow.Index + 1].Selected = true;
}
