DataTable dtCurrentTable = (DataTable)ViewState["CurrentTable"];

DataRow drCurrentRow = null;

if (dtCurrentTable.Rows.Count > 0)

TextBox TextBoxItem =

(TextBox)gvCheckList.Rows[rowIndex].Cells[1].FindControl("txtItem");

TextBox TextBoxSspSpec =

(TextBox)gvCheckList.Rows[rowIndex].Cells[2].FindControl("txtSspspec");

drCurrentRow = dtCurrentTable.NewRow();

drCurrentRow["RowNumber"] = i + 1;

dtCurrentTable.Rows[i - 1]["Col1"] = TextBoxItem.Text;

dtCurrentTable.Rows[i - 1]["Col2"] = TextBoxSspSpec.Text;

rowIndex++;

}

dtCurrentTable.Rows.Add(drCurrentRow);

ViewState["CurrentTable"] = dtCurrentTable;

gvCheckList.DataSource = dtCurrentTable;

gvCheckList.DataBind();

}

else

{

Response.Write("ViewState is null");

}

SetPreviousData();

try like this

protected void gvCheckList_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "New")
{
int index = Convert.ToInt32(e.CommandArgument);
AddNewRow(index);
}
}
