hiii,
if your staffname is string then do one more thing

XML

<asp:templatefield>
  <itemtemplate>
  <asp:checkbox id="chkOnlineCheck" runat="server" checked="<%# Eval("staffname").ToString() == "sample" ? false : true) %>" />' />
  </itemtemplate>
</asp:templatefield>

where replace follwing condition by your own

Eval("staffname").ToString() == "sample"

Hi ,
Check this

C#

protected void Page_Load(object sender, EventArgs e)
  {
      if (!IsPostBack)
      {
          GridView1.DataSource = GetData();
          GridView1.DataBind();
      }

  }
  DataTable GetData()
  {
      DataTable dt = new DataTable();
      using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString))
      {
          con.Open();
          using (SqlCommand cmd = new SqlCommand("select productid ,flag from product ", con))
          {

              SqlDataAdapter adpt = new SqlDataAdapter(cmd);
              adpt.Fill(dt);
          }

      }
      return dt;
  }

XML

<div>

    <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
        <Columns>
            <asp:TemplateField HeaderText="id">
                <ItemTemplate>
                    <asp:Label ID="Label1" runat="server" Text="<%# Bind('id') %>"></asp:Label>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="Check">
                <ItemTemplate>
                    <asp:CheckBox ID="CheckBox1" runat="server" Checked="<%# Bind('flag') %>" />
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

</div>
