您需要在所选行中找到标签和gridview。您的代码应如下所示：

protected void GridView3_RowCommand(object sender, GridViewCommandEventArgs e)
{
    int index = Convert.ToInt32(e.CommandArgument);
    GridViewRow selectedRow = GridView3.Rows[index];
    DateTime frmdt = this.DateRangePicker2.FromDate;
    DateTime Tomdt = this.DateRangePicker2.ToDate;
    if (e.CommandName == "btnPrvViewp")
    {

        if (selectedRow.Cells[1].Text == "Indirect Process" && selectedRow.Cells[2].Text == "SAP")
        {
            Label lbel1 = selectedRow.FindControl("lbel1") as Label;
            GridView GridView2 = selectedRow.FindControl("GridView2") as GridView;
            lbel1.Text = "Productivity Detaisl for the period " + frmdt + " To " + Tomdt;
            lbel1.Visible = true;
            SqlConnection conn = new SqlConnection(str2);
            SqlCommand com = new SqlCommand("ViewProductivity", conn);
            com.Parameters.Add("@fromDate", SqlDbType.DateTime).Value = frmdt;
            com.Parameters.Add("@ToDate", SqlDbType.DateTime).Value = Tomdt;
            conn.Open();
            com.CommandType = CommandType.StoredProcedure;
            SqlDataReader readerp = com.ExecuteReader();
            GridView2.DataSource = readerp;
            GridView2.DataBind();

            readerp.Close();

        }

    }
}

Gridview行命令事件不会更改ASP。页面控制行为
