I have a struct name datapoints which have the property (int x and string y) and the constructor takes a intger and a string to assign their value. I have also made a observablecollection of that struct datapoints. While making a collection i have passed string property FirstCell and SecondCell in first and second list and this FirstCell and SecondCell are the property which have Inotifyproperty change implemented. Now when i change this FirstCell and SecondCell they do not get changed in the datagrid.
Below is my code for MainWindow.xaml.cs file
public partial class MainWindow : Window,INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged = (sender, e) => { };
private string _FirstCell="LUFFY";
private string _SecondCell= "SANJI";
public string FirstCell
{
get { return _FirstCell; }
set
{
_FirstCell = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(FirstCell)));
}
}
public string SecondCell
{
get { return _SecondCell; }
set
{
_SecondCell = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(SecondCell)));
}
}
private ObservableCollection<datapoints> _CheckNotifyUpdate;
public ObservableCollection<datapoints> CheckNotifyUpdate
{
get { return _CheckNotifyUpdate; }
set
{
_CheckNotifyUpdate = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(CheckNotifyUpdate)));
}
}
public MainWindow()
{
InitializeComponent();
this.DataContext = this;
CheckNotifyUpdate = new ObservableCollection<datapoints>
{
new datapoints(1, FirstCell),
new datapoints(2, SecondCell)
};
}
}
public struct datapoints
{
public int x { get; set; }
public string y { get; set; }
public datapoints(int X,string Y)
{
x = X;
y = Y;
}
}
This is my XAML file
<Window x:Class="InotifyClassPropInsideList.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<StackPanel Orientation="Horizontal">

<Label Content="{ Binding FirstCell}"/>
</StackPanel>
<StackPanel Orientation="Horizontal">
<Label Content="The Second Cell Value is (Y2 in DataGrid) : "/>
<Label Content="{ Binding SecondCell}"/>
</StackPanel>
<Button Content="Button" Margin="50"/>
<DataGrid SelectedIndex="{Binding SelectedDataIndex, Mode=TwoWay}"
ItemsSource="{Binding CheckNotifyUpdate }" AutoGenerateColumns="True"
HorizontalAlignment="Center"></DataGrid>
</StackPanel>
</Window>
Current output is like this
I checked if the InotifyPropertychanged is implemented or not checking their value in the label below and it updates accordingly but the datagrid doesnot update. For example if i change the value of luffy and write Zoro in the first textbox then the first label in output (The First Cell Value(Y1 in DataGrid is):Zoro but the output in the Y table first row is still LUFFY.
P.S- I am writing this program to imitate my situation when i am trying to use datapoints from the OxyPlot so I must use struct and cannot use class for datapoints.

I changed the struct to class and everything work, but since your data comes by struct I think the below solution will for you.
Struct is a value type and binding will obtain a copy of it hence never update original object.
public partial class MainWindow : Window, INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged = (sender, e) => { };
private string _FirstCell = "LUFFY";
private string _SecondCell = "SANJI";
public string FirstCell
{
get { return _FirstCell; }
set
{
_FirstCell = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(FirstCell)));
RefreshGrid();
}
}
public string SecondCell
{
get { return _SecondCell; }
set
{
_SecondCell = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(SecondCell)));
RefreshGrid();
}
}
private ObservableCollection<datapoints> _CheckNotifyUpdate;
public ObservableCollection<datapoints> CheckNotifyUpdate
{
get { return _CheckNotifyUpdate; }
set
{
_CheckNotifyUpdate = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(CheckNotifyUpdate)));
}
}
public MainWindow()
{
InitializeComponent();
this.DataContext = this;
RefreshGrid();
}
private void RefreshGrid()
{
CheckNotifyUpdate = new ObservableCollection<datapoints>
{
new datapoints(1, FirstCell),
new datapoints(2, SecondCell)
};
}
}
public struct datapoints
{
public int x { get; set; }
public string y { get; set; }
public datapoints(int X, string Y)
{
x = X;
y = Y;
}
}
Change it to create the Collection every time when there is a change in cell value.

Sorry for late reply, May be i got it wrong but every time I change the value in the textbox it again retains its original value to (LUFFY). And i don't know if the property change is called or not. All i am adding in the code you wrote was the struct datapoints in .cs file. It still does not work :(

Nov 23 at 1:52
@mechbaral have you implemented the xaml as well since there is small change. For example intsead of First cell, it is First row.y.
– Satish Pai
Nov 23 at 2:07
Yes I have used the exact xaml that you posted. Actually when I change the value in textbox and click awa, the value in textbox immediately retains its original assigned value i.e. in our case LUFFY

}
public string SecondCell

public struct datapoints

Change it to create the Collection every time when there is a change in cell value.

Yes I have used the exact xaml that you posted. Actually when I change the value in textbox and click awa, the value in textbox immediately retains its original assigned value i.e. in our case LUFFY

I changed the struct to class and everything work, but since your data comes by struct I think the below solution will for you.
Struct is a value type and binding will obtain a copy of it hence never update original object.
public partial class MainWindow : Window, INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged = (sender, e) => { };
private string _FirstCell = "LUFFY";
private string _SecondCell = "SANJI";
public string FirstCell
{
get { return _FirstCell; }
set
{
_FirstCell = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(FirstCell)));
RefreshGrid();
}
}
public string SecondCell
{
get { return _SecondCell; }
set
{
_SecondCell = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(SecondCell)));
RefreshGrid();
}
}
private ObservableCollection<datapoints> _CheckNotifyUpdate;
public ObservableCollection<datapoints> CheckNotifyUpdate
{
get { return _CheckNotifyUpdate; }
set
{
_CheckNotifyUpdate = value;
PropertyChanged(this, new PropertyChangedEventArgs(nameof(CheckNotifyUpdate)));
}
}
public MainWindow()
{
InitializeComponent();
this.DataContext = this;
RefreshGrid();
}
private void RefreshGrid()
{
CheckNotifyUpdate = new ObservableCollection<datapoints>
{
new datapoints(1, FirstCell),
new datapoints(2, SecondCell)
};
}
}
public struct datapoints
{
public int x { get; set; }
public string y { get; set; }
public datapoints(int X, string Y)
{
x = X;
y = Y;
}
}
Change it to create the Collection every time when there is a change in cell value.

Sorry for late reply, May be i got it wrong but every time I change the value in the textbox it again retains its original value to (LUFFY). And i don't know if the property change is called or not. All i am adding in the code you wrote was the struct datapoints in .cs file. It still does not work :(

@mechbaral have you implemented the xaml as well since there is small change. For example intsead of First cell, it is First row.y.
