C#

protected void Button2_Click(object sender, EventArgs e)
   {
       DataTable dtNew = new DataTable("Employee Detils");
       dtNew.Columns.Add(new DataColumn() { ColumnName = "EmpName", DataType = typeof(String) });
       dtNew.Columns.Add(new DataColumn() { ColumnName = "EmpId", DataType = typeof(String) });



       for (int i = 0; i < GridView1.Rows.Count; i++)
       {
           if (GridView1.Rows[i].RowType == DataControlRowType.DataRow)
           {
               DataRow dr = dtNew.NewRow();

               dr["EmpName"] = GridView1.Rows[i].FindControl("button2");
               dr["EmpId"] = GridView1.Rows[i].FindControl("button2");

               dtNew.Rows.Add(dr);
               Session["Employee Details"] = dtNew;
               if (dtNew.Rows.Count > 0)
               {
                   string a = "Mr." + dr["EmpName"];
                   string b = "+91" + dr["EmpId"];
                   dr["EmpName"] = a;

                   dr["EmpId"] = b;

                   dtNew.Rows.Add(a, b);

try this

C#

protected void btnSave_Click(object sender, EventArgs e)
      {
          DataTable dtNew = new DataTable("Employee Detils");
          dtNew.Columns.Add(new DataColumn() { ColumnName = "EmpName", DataType = typeof(String) });
          dtNew.Columns.Add(new DataColumn() { ColumnName = "EmpId", DataType = typeof(String) });


          foreach (GridViewRow row in GridView1.Rows)
              if (row.RowType == DataControlRowType.DataRow)
              {
                  DataRow dr = dtNew.NewRow();
                  string empName = (row.FindControl("YourEmpNameControlId") as TextBox).Text;  // If it is a button replace the Textbox with button or the relevant control
                  string empId = (row.FindControl("YourEmpIdControlId") as TextBox).Text;  // If it is a button replace the Textbox with button or the relevant control
                  dr["EmpName"] = "Mr." + empName;
                  dr["EmpId"] = "+91" + empId;
                  dtNew.Rows.Add(dr);
              }
          GridView2.DataSource = dtNew;
          GridView2.DataBind();

      }
