how to go next row in datagridview

Question

hello

i use this method for go next row in datagridview
private void btnNext_Click(object sender, EventArgs e)
        {
            if (grdQustion.Rows.Count >= 1)
            {
                int i = grdQustion.CurrentRow.Index + 1;
                if (i >= -1 && i < grdQustion.Rows.Count)
                    grdQustion.Rows[i].Selected = true;

            }
        }
But I've written some code in grdQustion_RowEnter .When I go to the next row of code above the code will not run into grdQustion_RowEnter
Even CurrentRow. Index does not change

how can i go next row in datagridview with button??

See if this will work: private void btnNext_Click(object sender EventArgs e) { if (grdQustion.Rows.Count >= 1) { int i = grdQustion.CurrentRow.Index + 1; if (i >= -1 && i grdQustion.CurrentCell = grdQustion.Rows[i].Cell[0]; } }

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; }
