Solution 2

If you would like to use the components and controls which are defined in the namespace "System.Windows.Forms", you need to add a reference to it by right mouse clicking the project in the solution explorer and choosing "Add Reference" in the context menu -> Tab "Net" -> "System.Windows.Forms".

For more details refer MSDN[^]

to navigate to the next button of the datatable:
protected void Button1_Click(object sender, EventArgs e)
{

int rowIndex = 0;

if (Hidden_id.Value.Trim() != null)
{
rowIndex = Convert.ToInt32(Hidden_id.Value) + 1;

if (Session["dt"] != null)
{

DataTable dt = (DataTable)Session["dt"];

if (rowIndex < dt.Rows.Count)
{

//get the next row entry on Button Click by setting the Row Index
txt_kodi.Value = dt.Rows[rowIndex]["Code"].ToString();

txt_tel.Value = dt.Rows[rowIndex]["Tel"].ToString();

txt_mobile.Value = dt.Rows[rowIndex]["Mobile"].ToString();

Session["dt"] = dt;
Hidden_id.Value = rowIndex.ToString();

}
else

MessageBox.Show("Last record!");

}

}
}
