Hi,

Please refer below code.

HTML

<asp:CheckBoxList ID="chkList" runat="server" RepeatColumns="5" RepeatDirection="Horizontal">
</asp:CheckBoxList>

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable pagelist = new DataTable();
        pagelist.Columns.Add("Page");
        pagelist.Rows.Add("1");
        pagelist.Rows.Add("2");
        pagelist.Rows.Add("3");
        pagelist.Rows.Add("4");
        pagelist.Rows.Add("5");
        pagelist.Rows.Add("6");
        pagelist.Rows.Add("7");
        pagelist.Rows.Add("8");
        pagelist.Rows.Add("9");
        pagelist.Rows.Add("10");
        chkList.DataSource = pagelist;
        chkList.DataTextField = "Page";
        chkList.DataValueField = "Page";
        chkList.DataBind();
        DataTable checklist = new DataTable();
        checklist.Columns.Add("check");
        checklist.Rows.Add("1");
        checklist.Rows.Add("3");
        checklist.Rows.Add("5");
        checklist.Rows.Add("7");
        foreach (ListItem item in chkList.Items)
        {
            if (checklist.AsEnumerable().Select(x => x["check"]).ToArray().Contains(item.Value))
            {
                item.Selected = true;
            }
        }
    }
}
