WPF Datagrid Set Value Outside ICollectionView

So I have a DataGrid which is bound to a ICollectionView.
Now, I have one column which I want it to be bound not to the ICollectionView, but to a local variable from inside of the class.
How do I make that in the code?
<DataGrid
x:Name="DG_StudentsList"
FontSize="20"
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center"
AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Id}" Header="מ''ס"/>
<DataGridTextColumn Binding="{Binding Name}" Header="שם"/>
<DataGridTextColumn Binding="{Binding PhoneNum}" Header="טלפון"/>
<DataGridTemplateColumn Header="ספרים מושאלים">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<ComboBox ItemsSource="{Binding Path=BorrowedBooks}" DisplayMemberPath="BookName" SelectionChanged="CB_BookName_SelectionChanged"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>
</DataGrid.Columns>
</DataGrid>
Just to be clear, I want to add a new DataGridTextColumn which is the one that will be bound to the local variable.

No, you can't bind to a local variable. First of all, there is a local scope, a instance scope and a class scope. A local variable only lives in a local scope e.g. the block of an if-statement or a method body. As soon the instruction pointer leaves this scope the variable does no longer exist. You may mean an instance variable i.e. field, which lives as long as the object instance is living. Class variables would be static fields, variables that don't belong to the class instance, but the class itself.
Anyway, you can only bind to public properties. Microsoft Docs: Binding Source Types
If you have a public property, then you can also bind a column to it.
A common CLR property would also work. But in controls it is recommended to implement properties that serve as a binding source as DependencyProperty.

How to get values of same column from n number of user control datagridview in main form button click event

I am working on windows form application. I created user control which has datagridview control. I added dynamically 10 user control in a panel(which is in main form) which has "Observed(sec)" column in common. In this column user will enter values.And click on save button. All the values will get saved in text file.
My question is : I added everytime a new user control in a panel. Then how to get values from Observed column to save button?

userSelection.Add(c.name)

Take a close look at what you are doing
foreach (var addedUser in userSelection.ToArray())
{
if (!addedUser.Contains(c.name))
{
userSelection.Add(c.name);
}
}
You are adding to userSelection in the userSelection loop
The test is on !addedUser.Contains
You should not even be able to do that but I think the ToArrray() is letting it happen
So you add Sally
Then then Mark
Then you add Mark again because in the loop Mark != Sally
You are not using List<String> managerNames = new List<String>();
private void findManagerForSelectedDate(String dateSelected)
{
dateSelected = dateTimePicker1.Value.ToShortDateString();
You pass in dateSelected, then overright with dateTimePicker1, and then you don't even use it
Most of you code makes very little sense to me

Ok after I try it this is working solution for me.
Probably its diferent namespace but all components have same name.

Silverlight 4.0 reading complex xml with linq

I'm stuck with following XML problem.
This is my XML file:
<POIs lastUsedId="9000010">
<POI id="9000010" name="München"><Latitude>48.139126</Latitude><Longitude>11.5801863</Longitude>
<Address>muenchen</Address><PhotoDescription>Hofbräuhaus</PhotoDescription>
<Photos directory="_x002F_pics"><PhotoFile>pic4poi_9000010-01.jpg</PhotoFile>
<PhotoFile>pic4poi_9000010-02.jpg</PhotoFile><PhotoFile>pic4poi_9000010-03.jpg</PhotoFile>
<PhotoFile>pic4poi_9000010-04.jpg</PhotoFile></Photos>
<InformationFile>infos\info4poi_9000010.txt</InformationFile></POI>
</POIs>
And here is my code to read the file:
XDocument doc = XDocument.Load(s);
lastID = Int32.Parse(doc.Root.Attribute("lastUsedId").Value.ToString());
CultureInfo cultureInfo = new CultureInfo("en-GB");
var pois = from res in doc.Descendants("POI")
select new
{
id = Int32.Parse(res.Attribute("id").Value.ToString()),
name = res.Attribute("name").Value.ToString(),
latitude = Double.Parse(res.Element("Latitude").Value, cultureInfo),
longitude = Double.Parse(res.Element("Longitude").Value, cultureInfo),
address = res.Element("Address").Value.ToString(),
photoDesc = res.Element("PhotoDescription").Value.ToString(),
photoDir = XmlConvert.DecodeName(res.Element("Photos").Attribute("directory").Value.ToString()),
photoFiles = from a in doc.Descendants("Photos")
select new
{
photo = a.Element("PhotoFile").Value.ToString()
},
info = res.Element("InformationFile").Value.ToString()
};
foreach (var poi in pois)
{
IEnumerable<string> pF = (poi.photoFiles as IEnumerable<string>);
List<string> photoFiles = null;
if(pF != null)
photoFiles = pF.ToList<string>();
AddPushpin(poi.id, poi.name, poi.latitude, poi.longitude, poi.address, poi.photoDesc, poi.photoDir, photoFiles, poi.info);
};
I'm unsure about the part with the PhotoFiles because I get an unknown Object error when I try to read the Pushpin.
This what my Pushpin looks like:
public class MyPushpin : Pushpin
{
public int ID { get; set; }
public string Address { get; set; }
public string PhotoDesc { get; set; }
public string PhotoDir { get; set; }
public List<string> PhotoFiles { get; set; }
public MyPushpin() { }
public MyPushpin(int id, string name, double latitude, double longitude, string address, string photoDesc, string photoDir, List<string> photoFiles, string info)
{
Location loc = new Location(latitude, longitude);
this.ID = id;
this.Location = loc;
this.Name = name;
this.Address = address;
this.PhotoDesc = photoDesc;
this.PhotoDir = photoDir;
this.PhotoFiles = photoFiles;
this.Tag = info;
}
public void Update(string name , string photoDesc, List<string> photoFiles, string info)
{
this.Name = name;
this.PhotoDesc = photoDesc;
this.PhotoFiles = photoFiles;
this.Tag = info;
}
public override string ToString()
{
return String.Format("{0} - {1}", this.ID, this.Location, this.Address, this.PhotoDesc, this.PhotoDir, this.Tag);
}
And that's the code how I would like to use the file info in the custom Pushpin:
public partial class Gallery : ChildWindow
{
List<string> pics = null;
public Gallery(MyPushpin currentPin)
{
InitializeComponent();
pics = currentPin.PhotoFiles;
Loaded += (a, b) => {
LoadImages();
};
}
private void OKButton_Click(object sender, RoutedEventArgs e)
{
this.DialogResult = true;
Close();
}
private void CancelButton_Click(object sender, RoutedEventArgs e)
{
this.DialogResult = false;
Close();
}
private void LoadImages()
{
List<Picture> coll = new List<Picture>();
pics.ForEach(delegate(String url)
{
coll.Add(AddPicture("url"));
});
//coll.Add(AddPicture("/pics/pic4poi_9000010-01.jpg"));
//coll.Add(AddPicture("/pics/pic4poi_9000010-02.jpg"));
//coll.Add(AddPicture("/pics/pic4poi_9000010-03.jpg"));
//coll.Add(AddPicture("/pics/pic4poi_9000010-04.jpg"));
Preview.Source = new BitmapImage(
new Uri(
"/pics/pic4poi_9000010-01.jpg",
UriKind.Relative));
lbImage.ItemsSource = coll;
}
private Picture AddPicture(string path)
{
return new Picture
{
Href = new BitmapImage(
new Uri(
path,
UriKind.Relative))
};
}
private void lbImage_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
Preview.Source = ((Picture)lbImage.SelectedItem).Href;
}
}
public class Picture
{
public ImageSource Href { get; set; }
THX for your time

Could you please describe the problem that you are having in more detail. Have you debugged into it, where does it fail, what is the exception? What do you expect it to do.
Off the top of my head, this code looks wrong:
photoFiles = from a in doc.Descendants("Photos")
select new
{
photo = a.Element("PhotoFile").Value.ToString()
},
Replace doc with res, because you want the child elements of the current element, not of the document. Also you can use Elements here instead of Descendants since they are direct children. Also since there are multiple photo files, try a SelectMany (from a ... from b ...):
photoFiles = from a in res.Elements("Photos")
from b in a.Elements("PhotoFile")
select new
{
photo = b.Value.ToString()
},
