Hi
I have been trying to add a new row and add textbox value in my gridview but only if the gridview is not empty. Now I managed to add textbox value if the gridview is empty am strugling with adding a new row. Check the code below on how to add textbox value to a gridview

DataTable dT = new DataTable();
            dT.Columns.Add("Reason", typeof(string));
            Session["dt"] = dT;

       DataTable dTable=(DataTable)Session["dt"];
       DataRow dr = dT.NewRow();

            if(grvPayments.Rows.Count==0)
            {
       dr["Reason"] = txtReason.Text;


           dTable.Rows.Add(dr);


           grvPayments.DataSource = dT;
           grvPayments.DataBind();
            }
      else
           {
             //Create new row and add textbox value

            }

推荐答案

DataTable dT = new DataTable();
if(Session["dt"]=null)
{
   dT.Columns.Add("Reason", typeof(string));
   DataRow dr = dT.NewRow();
   dr["Reason"] = txtReason.Text;
   dT.Rows.Add(dr);
   Session["dt"] = dT;
   grvPayments.DataSource = dT;
   grvPayments.DataBind();
}
else
{
   dT=(DataTable)Session["dt"];
   DataRow dr = dT.NewRow();
   dr["Reason"] = txtReason.Text;
   dT.Rows.Add(dr);
   Session["dt"] = dT;
   grvPayments.DataSource = dT;
   grvPayments.DataBind();
}
