Thank you for your reply. Sorry for my english too.

I would to modifiy my checkbox to button style. I used this :

<CheckBox x:Name="cbxIlots" Tag="{Binding strCodeIlot}" Style="{StaticResource {x:Type ToggleButton}}" Content="{Binding strDesIlot}" FontSize="14" Margin="25,15,25,15" Width="225" Height="45" IsChecked="{Binding bChecked}" Checked="cbxIlots_Checked" Unchecked="cbxIlots_Unchecked" />

I set the style "togglebutton" to my checkbox.

It's work, great.

But i need to have a button, with two text, for example, TITLE, Font size 14, bold and below, a text, for example, DESCRIPTION, Font size 10, italic.

And, if my checkbox is checked, an image with background blue, and is not checked, with background purple, for example.

How i do make this ?

Thank you in advance. If the good solution is to not use a user control i would use the great solution to get my result.

I can work with this code on my main project XAML :

<Window x:Class="Plutus.SelectionIlot"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<window.resources>

&lt;Setter Property="Template">

&lt;ControlTemplate TargetType="{x:Type CheckBox}">
&lt;StackPanel Orientation="Horizontal">

Yes, sorry, i will say user control

My control work, but i need a property IsChecked too

Yes, i come from Winforms.

Can you give me more information ?

I created a DLL with my custom control. It's not correct ?

I created a project type library of user controle WPF and i insert my DLL on my project.

It's ok but i don't have the property checked

Hello
In my C# User Control i have

public bool IsChecked
{
get { return (bool)GetValue(IsCheckedProperty); }
set { SetValue(IsCheckedProperty, value); }
}

I need to check / uncheck my button if bChecked is true or false

Thank you

Great thank you

I begin to understand binding!

Thank you very much

Hello

Just, how make this : Then, loop over your collection

I have add this code , when i learn for my data on my another topic

public partial class SelectionLigne : Window, INotifyPropertyChanged
{
#region Évenement qui permet de déclencher l'événement INotifyPropertyChanged et mettre à jour le binding
public void Set<tvalue>(ref TValue field, TValue newValue, [CallerMemberName] string propertyName = "")
{
if (EqualityComparer<tvalue>.Default.Equals(field, default(TValue)) || !field.Equals(newValue))
{
field = newValue;

if (PropertyChanged != null)
PropertyChanged.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}

public event PropertyChangedEventHandler PropertyChanged;
#endregion

private bool IsChecked;
public bool bChecked
{
get { return IsChecked; }
set { Set(ref IsChecked, value); }
}

Ok, thank you , it's great, it's work.

But i have a problem now with this variable :

private string _strTotaux;
public string strTotaux
{
get { return _strTotaux; }
set { _strTotaux = value; }
}



it no view in my screen, but before the modification it's ok

I don't understand why

I don't have any error of bindings

I need to use NotifyChangedProperty when i fill my variable ?

strTotaux = "Nb OPs : " + dblTotalOp.ToString() + " Qte totale : " + dblTotalQte.ToString() + " Pces Temps total : " + dblTotalTemps + " Hrs";

Thank you

If i understand, i add the code

public class RangeObservableCollection<t> : ObservableCollection<t>
{
private bool _suppressNotification = false;

protected override void OnCollectionChanged(NotifyCollectionChangedEventArgs e)
{
if (!_suppressNotification)
base.OnCollectionChanged(e);
}

public void AddRange(IEnumerable<t> list)
{
if (list == null)
throw new ArgumentNullException("list");

_suppressNotification = true;

foreach (T item in list)
{
Add(item);
}
_suppressNotification = false;
OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset));
}
}

In my MainWindow.xaml.cs ?

But i don't understand how i call AddRange, sorry :(

It's my first week in WPF

Sorry but i don't see a link

I tried to use .AddRange but it's not possible on an observablecollection

I see

Hello
Thank you for your reply
I don't have *.AddRange.
I have only _lstOperations.Add

Because, it's not a list, it's an ObservableCollection

Thank you

Hello

Thank you very very much

But, this solution has create a small new problem

Can you please read my topic :

https://www.codeproject.com/Questions/1207251/Csharp-WPF-refresh-ecran

If you look this topic (sum) you can see my first code, with the datacontext with the list is ok, but now, we changed the datacontext with this thank you

Thank you very much

I have an error on this :

public ObservableCollection<cl_operation> lstOperationsTemp { get; set; } = new ObservableCollection<cl_operation>();

Error 1 Invalid '=' token in the declaration of members of the class, structure, or interface
Error 1 Invalid '(' token in the declaration of members of the class, structure, or interface

EDIT : this code Work :

private ObservableCollection<cl_operation> _lstOperationsTemp = new ObservableCollection<cl_operation>();
public ObservableCollection<cl_operation> LstOperationsTemp
{
get { return _lstOperationsTemp; }
set
{
_lstOperationsTemp = value;
}
}

In XAML :

<ScrollViewer VerticalScrollBarVisibility="Auto" Grid.Row="3" >
<ItemsControl VerticalAlignment="Top" x:Name="lvDataBinding" HorizontalContentAlignment="Stretch" BorderThickness="0" Margin="10" Grid.Row="3" Background="{x:Null}" ItemsSource="{Binding LstOperationsTemp}" Foreground="White">

It's work, i see my data in my grid but, in my label, my strTotaux didn't show :

I work on a copy of my project. But i don't find why it's doesnt work

I removed this DataContext :

Application.Current.Dispatcher.Invoke(new Action(() => this.DataContext = lstOperations));

and i replace by this :

DataContext = this; in MainWindow()

In my XAML i specify ItemsSource="{Binding CL_Operation}" in my <ItemsControl ItemsSource="{Binding CL_Operation}">

Now i don't have any data in my view

I test, i check, i try to understand, sorry... thank you for your help

Hello, thank you.

I changed DataContext = this, it's ok.

In my XAML i change this code :
<ItemsControl VerticalAlignment="Top" x:Name="lvDataBinding" HorizontalContentAlignment="Stretch" BorderThickness="0" Margin="10" Grid.Row="3" Background="{x:Null}" ItemsSource="{Binding}" Foreground="White">

by this code :

<ItemsControl VerticalAlignment="Top" x:Name="lvDataBinding" HorizontalContentAlignment="Stretch" BorderThickness="0" Margin="10" Grid.Row="3" Background="{x:Null}" ItemsSource="{Binding CL_Operation}" Foreground="White">

But my data view in my screen is empty now. I have two binding errors :

System.Windows.Data Error: 40 : BindingExpression path error: 'CL_Operation' property not found on 'object' ''MainWindow' (Name='')'. BindingExpression:Path=CL_Operation; DataItem='MainWindow' (Name=''); target element is 'ItemsControl' (Name='lvDataBinding'); target property is 'ItemsSource' (type 'IEnumerable')
System.Windows.Data Error: 40 : BindingExpression path error: 'strTotaux' property not found on 'object' ''MainWindow' (Name='')'. BindingExpression:Path=strTotaux; DataItem='MainWindow' (Name=''); target element is 'Label' (Name=''); target property is 'Content' (type 'Object')

If you need i can send my XAML in .txt file

Graeme_Grant

For the DataContext i haven't nothing modify. I set always the datacontext :

Application.Current.Dispatcher.Invoke(new Action(() => this.DataContext = lstOperations));

In my void GetList();

I don't have any binding errors

Thank you

Hello

Thank you very much for your reply.

But, i don't understand, why the new syntax do not work ? With the old syntax it's ok.

I'm using Visual Sutdio 2012, it's the reason ?

For my problem : i see my data in the view, before it's worked too.

With your code, it's fastly than with my code.

But my problem is not solved.

In my label in XAML with my binding strTotaux, it's always the registre [0] to display of my classe CL_Operation, but nut the sum

I calculate the sum in my for loop :

dblTotalQte += Convert.ToDouble(dvOps[i]["QtePoste"].ToString().Trim());
dblTotalTemps += Convert.ToDouble(dvOps[i]["TpsChargePoste"].ToString().Trim());
dblTotalOp++;


clOp.strTotaux = "Nb OPs : " + dblTotalOp.ToString() + " Qte totale : " + dblTotalQte.ToString() + " Pces Temps total : " + dblTotalTemps + " Hrs";

Thank you.

Hello, yes, it's work :

public class CL_Operation : ObservableBase is ok.

I have an error on

PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); and on

get => _strRetardAvanceText;

Thank you very much, very much very much

Hello

Thank you for your reply

I have error on :

PropertyChanged?.Invoke :

Invalid expression term '.'
only an assignment, call, increment, decrement, expectation, and new object expressions can be used as a statement
the name 'Invoke' does not exist in the current context
Syntax error, ':' expected

In my classe i have an error :

get => _strWidth; : error on "=>" : { or ; excepted

Thank you very much in advance.

Hello
Ok, i can try, my english is very bad.
