How to read multiple node element from xml data in c#

I have xml like below. Here allowedSessionType can be multiple value sometime. Could anyone help me to read both and store it into data table c# gridview.
I tried but getting single value
<sessionManagementSubscriptionData>
<singleNssai>1-000001</singleNssai>
<dnnConfiguration>
<pduSessionTypes>
<defaultSessionType>IPV4</defaultSessionType>
<allowedSessionType>IPV4</allowedSessionType>
</pduSessionTypes>
<sscModes>
<defaultSscMode>SSC_MODE_1</defaultSscMode>
<allowedSscMode>SSC_MODE_1</allowedSscMode>
</sscModes>
</dnnConfiguration>
<dnnConfiguration>
<pduSessionTypes>
<defaultSessionType>IPV4</defaultSessionType>
<allowedSessionType>IPV4</allowedSessionType>
<allowedSessionType>IPV6</allowedSessionType>
</pduSessionTypes>
<sscModes>
<defaultSscMode>SSC_MODE_1</defaultSscMode>
<allowedSscMode>SSC_MODE_1</allowedSscMode>
</sscModes>
</dnnConfiguration>
</sessionManagementSubscriptionData>
DataTable dt1 = new DataTable();
dt1.Columns.Add("Allowed Session Type", typeof(string));
XmlNodeList nodeList1 = doc.SelectNodes("//sessionManagementSubscriptionData/dnnConfiguration");
foreach (XmlNode node1 in nodeList1)
{
DataRow dtrow1 = dt1.NewRow();
var SMSDDefaultSessionType = node1.SelectSingleNode("//defaultSessionType").InnerText;
dtrow1["Default Session Type"] = SMSDDefaultSessionType;
var SMSDallowedSessionType = node1.SelectSingleNode("//allowedSessionType").InnerText;
dtrow1["Allowed Session Type"] = SMSDallowedSessionType;
dt1.Rows.Add(dtrow1);
}
GridView2.DataSource = dt1;
GridView2.DataBind();

using System.Xml.Serialization;
XmlSerializer serializer = new XmlSerializer(typeof(SessionManagementSubscriptionData));
using (StringReader reader = new StringReader(xml))
{
var test = (SessionManagementSubscriptionData)serializer.Deserialize(reader);
//test.DnnConfiguration has your data
}

C# need to store a parsed version of SQL Server table, use datatable or list

I'm new to C#. I know that datatable is very efficient for reading an entire SQL table and outputting data to griddataview. However I need to do some parsing before storing the data in my griddataview. I was thinking reading the table row by row and grouping the data when applicable. Would a datatable or a list be more applicable in my case?
ORIGINAL TABLE PARSED TABLE I need to pass to datagridview
Name Workdate Name M T W TH F SAT SUN
Nicole WED Nicole Y Y Y
Nicole THR Jason Y
Nicole MON
Jason Tue

Try following :
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Dictionary<string, string> dict = new Dictionary<string, string>() {
{"MON", "M"},{"TUE", "T"},{"WED", "W"},{"THR", "TH"},{"FRI", "F"},{"SAT", "SAT"},{"SUN", "SUN"}};
DataTable dt = new DataTable();
dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Workdate", typeof(string));
dt.Rows.Add(new object[] { "Nicole", "WED" });
dt.Rows.Add(new object[] { "Nicole", "THR" });
dt.Rows.Add(new object[] { "Nicole", "MON" });
dt.Rows.Add(new object[] { "Jason", "TUE" });
DataTable pivot = new DataTable();
pivot.Columns.Add("Name",typeof(string));
DataColumn[] columns = dict.Select(x => new DataColumn(x.Value, typeof(string))).ToArray();
pivot.Columns.AddRange(columns);
var people = dt.AsEnumerable().GroupBy(x => x.Field<string>("Name")).ToArray();
foreach (var person in people)
{
DataRow pivotRow = pivot.Rows.Add();
pivotRow["Name"] = person.Key;
foreach (DataRow row in person)
{
string day = row.Field<string>("Workdate");
pivotRow[dict[day]] = "Y";
}
}
}
}

How to Display data horizontally

I have four tables (employees, allowances,deductions and Ajenda these are main tables , when i save employees financial details i save them in a different tables as image .
I want to display the employees detail and financial details in a horizontally way .
I'm using C# and SQLServer 2012 .
first table contains employees main details , second contain employees id with there allowances and other tables .
My tables

Here is my code before somebody closes it again. I decided not to use group since there would be a lot of left outer joins which would complicate solution. Decided just to create a table and then add the data directly to the results table.

hierarchical treeview in c# Winforms with continent, nation, city

I have a SQL table:
REGION NATION CITY
Europe Austria Wien
Europe Austria Graz
APA Australia Sidney
Etc...etc...
Basically, region, nation, and city.
I would like to build a hierarchical Treeview like:
-EUROPE
--Austria
---Graz
---Wien
-APA
--Australia
---Sydney
I used Datatable to get data from a database.
Someone can help me with the cycle FOR and various nested if to accomplish that?
Many thanks in advance

Try following :
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication51

try

dt.Columns.Add("REGION", typeof(string));
dt.Columns.Add("NATION", typeof(string));
dt.Columns.Add("CITY", typeof(string));
dt.Rows.Add(new object[] { "Europe", "Austria", "Wien" });
dt.Rows.Add(new object[] { "Europe", "Austria", "Graz" });
dt.Rows.Add(new object[] { "APA", "Australia", "Sidney" });
foreach (var region in dt.AsEnumerable().GroupBy(x => x.Field<string>("REGION")))
{
TreeNode regionNode = new TreeNode(region.Key);
treeView1.Nodes.Add(regionNode);
foreach (var nation in region.GroupBy(x => x.Field<string>("NATION")))

TreeNode nationNode = new TreeNode(nation.Key);
regionNode.Nodes.Add(nationNode);
foreach (string city in nation.Select(x => x.Field<string>("CITY")))

C# dataGridView from XML file

I know there are lots of resources that show how to bind dataGridViews to XML files or populate from XML, but the XML i'm using as source is a bit more complex than any example I've seen used and I'm struggling. (although it really shouldn't be difficult)
I basically need to run several queries (I think) to get the data I want to populate the DGV, because the elements I want the content from are on different parent nodes of the XML.
Here is what I have, and the comments should show you what I'm trying to achieve:
XDocument xmlDoc = XDocument.Load("Techdocx_dml.xml");
var q = from c in xmlDoc.Root.Descendants("dmentry")
.Descendants("avee")
//.Descendants("dmtitle") I also need to access this descendant
select new
{
modelic = c.Element("modelic").Value,
sdc = c.Element("sdc").Value,
chapnum = c.Element("chapnum").Value,
section = c.Element("section").Value,
subsect = c.Element("subsect").Value,
subject = c.Element("subject").Value,
discode = c.Element("discode").Value,
discodev = c.Element("discodev").Value,
incode = c.Element("incode").Value,
incodev = c.Element("incodev").Value,
itemloc = c.Element("itemloc").Value,
// techname = c.Element("techname").Value,
//need this value, which is on the "dmtitle" node, not the "avee" node
};
dataGridView1.DataSource = q.ToList();
dataGridView1.ColumnHeadersVisible = false;
dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells;
This is what i want in my dataGridView:
AA A 32 3 5 00 01 A 018 A A | Some title 1 | Introduction
AA A 32 3 5 00 01 A 920 A A | Some title 2 | Some infoname 2
How do I achieve this please? Example XML below:
<dml xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<dmentry>
<addresdm>
<dmc>
<avee>
<modelic>AA</modelic>

<incode>018</incode>
<incodev>A</incodev>
<itemloc>A</itemloc>
</avee>
</dmc>
<dmtitle>
