WPF - binding Inside a collection

2022-05-04 21:08 Disvoys imported from Stackoverflow

I'm looking to bind a specific element of a list.

Public Class itemCATIA

    Property l As New List(Of itemCATIAProperties) 'the list

   Sub New(d)
    For Each item As Parameter In pCATIA.UserRefProperties
                Dim myP As New itemCATIAProperties(item.Name, 
                 item.ValueAsString)
                l.Add(myP)  'the list
     Next
    end sub

end class

Public Class itemCATIAProperties

    Property Name As String
    Property Value As String

    Sub New(item As String, _value As String)
        Dim s() As String = Strings.Split(item, "\")
        Name = s(UBound(s))
        Value = _value
    End Sub
End Class

and below my tests to bind the correct value inside a dynamically created column :

 Private Sub Window_Loaded(sender As Object, e As RoutedEventArgs)

        Dim c As New DataGridTextColumn
        c.Header = "MASS"
        c.Binding = New Binding("l[Name='MASS'].Value") 'does not work
        c.Binding = New Binding("l[0].Value") 'does not return the good index of my list l. i want index=c.header
        MaDataGrid.Columns.Add(c)
    End Sub

Is there a method to retrieve the value whose index is the column header ?

Thanks a lot :)

Well i resolved with something not very beautiful.. if someone get a best solution, i take :)

i replaced in the sub new() :

    Dim l_ As New List(Of itemCATIAProperties)
    For Each item As Parameter In pCATIA.UserRefProperties
        Dim myP As New itemCATIAProperties(item.Name, item.ValueAsString)
        l_.Add(myP)
    Next

    For i = 1 To 30
        l.Add(Nothing)
    Next
    For Each item In l_
        Select Case item.Name
            Case "MATERIAL"
                l(0) = item
            Case "OBSERVATIONS"
                l(1) = item
            Case "LENGTH"
                l(2) = item
            Case "LENGTH"
                l(3) = item
            Case "THICKNESS/DIAMETER"
                l(5) = item
            Case "MASS"
                l(5) = item
            Case "SUPPLIER"
                l(6) = item
            Case "REF"
                l(7) = item
            Case "TTS"
                l(8) = item
            Case "SYM"
                l(9) = item
            Case "NomPuls_Marquage"
                l(10) = item
            Case "NomPuls_Traitement"
                l(11) = item
            Case "NomPuls_Protection"
                l(12) = item
            Case "NomPuls_Dim_Brutes"
                l(13) = item
            Case "NomPuls_Masse"
                l(14) = item
            Case "NomPuls_Matiere"
                l(15) = item
            Case "NomPuls_Designation"
                l(16) = item
            Case "NomPuls_Indice"
                l(17) = item
            Case "NomPuls_Planche"
                l(18) = item
            Case "DETAIL NUMBER"
                l(19) = item
            Case "STOCK SIZE"
                l(20) = item
        End Select
    Next

Implementing mouse stroke detection similar to InkCanvas
My problem effectively boils down to accurate mouse movement detection.

I need to create my own implementation of an InkCanvas and have succeeded for the most part, except for drawing strokes accurately.
```
void OnMouseMove(object sneder, MouseEventArgs e)
{
    var position = e.GetPosition(this);
    
    if (!Rect.Contains(position))
        return;
    
    var ratio = new Point(Width / PixelDisplay.Size.X, Height / PixelDisplay.Size.Y);
    var intPosition = new IntVector(Math2.FloorToInt(position.X / ratio.X), Math2.FloorToInt(position.Y / ratio.Y));

    DrawBrush.Draw(intPosition, PixelDisplay);
    UpdateStroke(intPosition); // calls CaptureMouse
}
```
This works. The Bitmap (PixelDisplay) is updated and all is well. However, any kind of quick mouse movement causes large skips in the drawing. I've narrowed down the problem to e.GetPosition(this), which blocks the event long enough to be inaccurate.

There's this question which is long beyond revival, and its answers are unclear or simply don't have a noticeable difference. After some more testing, the stated solution and similar ideas fail specifically because of e.GetPosition.

I know InkCanvas uses similar methods after looking through the source; detect the device, if it's a mouse, get its position and capture. I see no reason for the same process to not work identically here.
WPF Textbox Validation Error binded to Variable
In a .xaml file, I have a number of Textbox objects that are linked to data paths as such:
```
<TextBox Text="{Binding Path=Var1}">
```
These variables (like Var1) are all linked to double values, and as such, if a user attempts to input a non-double value like a string or an empty value, the box is highlighted red. I assume this is the default validation error.

I'd like to know if it's possible to set a boolean to true in my code-behind whenever one of these Textbox objects are highlighted red, and then set back to false when it's not highlighted red. In other words, I'd want to set the boolean to true whenever a user causes the default Textbox validation error, and to false when the error is resolved.

Additionally, I notice that this validation error fires off when the Textbox loses focus; i.e. when the user clicks off of that Textbox or moves to a different Textbox. Is it possible for the validation error to fire off on each keystroke instead?

Thanks. I'm something of a WPF beginner, but it's been hard to find specifics about my issue, and I suspect it'll be useful information to understand data validation down the road.
How to nest formatted strings in XAML?
Is it possible to nest formatted strings in XAML without creating a custom class?

Here is an example of what I want to achieve:
- Format a string, e.g. "inner start {0} inner end".
- Format the previous resultant string, e.g. "outer start {0} outer end".
- Use the final string as the Text of a TextBlock.
As a concrete example, if "foo" was the string to be formatted, I would require the final string to be:

"outer start inner start foo inner end outer end"

I am able to format a single string with the following:
```
<TextBlock
Text="{Binding Source={x:Static res:Resources.Foo}, StringFormat={x:Static res:Resources.Bar}}" />
```
However, attempting to bind one Binding to another results in an error:
```
<TextBlock
Text="{Binding Source={Binding Source={x:Static res:Resources.Foo}, StringFormat={x:Static res:Resources.Bar}}, StringFormat={x:Static res:Resources.Baz}}" />
```
I think this could be achieved with an IMultiValueConverter, but I don't know if there is a simpler way.

treeview grandfather,parent and son names

I have tree view which has grandfather node and inside of this grandfather there is parent and inside this parent there is son node. How I can get the names of this grandfather , parent and son nodes. I already did the code to work when the user double clicks on the son node, but still I am unable to get the names for the grandfather, parent and child nodes. here is my code:

 Private Sub TreeView1_NodeMouseDoubleClick(sender As Object, e As TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseDoubleClick

        Dim ClickPoint As Point = New Point(e.X, e.Y)

How to bind an imageSource from a List of Image items in .NET MAUI

I'm developing an app that will soon have a server/DB. I want toaccomplish the binding between the List images and the xaml. Any idea of how to proceed?

 public class Profile : INotifyPropertyChanged
{
    /** --------------------------------------------------------------------
    *                           Properties

    List<Image> images;
    public List<Image> Images
    {
        get { return images; }
        set { images = value; OnPropertyChanged(nameof(Images)); }
    }
public Profile()
    {
        Images.Add(new Image());
        Images.Add(new Image());

How to pass ActivityBinding variable as argument to another Activity functions in AndroidStudio (Java)?
I use the data binding tool in order to get xml elements in my java code.

Is there a way to pass the ActivityBinding variable as an argument from its Activity to a function set inside another activity ?

For example, here is my ActivityBinding of the HomeActivity:
```
private ActivityHomeBinding binding;

 @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        binding = ActivityHomeBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());
    }
```
Is there a way to pass this "binding" variable as an argument/parameter to function of another activity and use it inside the another activity as the ActivityBinding of the HomeAtivity ?

Thank You.

NotifyPropertyChanged not works in some cases

I have the next base implementation of INotifyPropertyChanged interface

public abstract class PropertyChangedBase : INotifyPropertyChanged
{
    /// <summary>
    /// Raised when the ViewModel property is changed.
    /// </summary>
    public event PropertyChangedEventHandler PropertyChanged;

    /// <summary>
    /// Notifies subscribers about changing property or properties. 
    /// </summary>
    /// <param name="propertyName">Changed property name(s).</param>
    protected void NotifyPropertyChanged(params string[] propertyName)
    {
        foreach (string pn in propertyName)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(pn));
        }
    }
}

The property looks like this.

private string speciality;
public string Speciality
{
    get => speciality;
    set { speciality = value; NotifyPropertyChanged(nameof(Speciality)); }
}

And row in my DataGrid successfull updated when NotifyPropertyChanged(...) called

But now I extanded PropertyChangedBase class with GetValue/SetValue methods like this

public abstract class PropertyChangedBase : INotifyPropertyChanged
{
    /// <summary>
    /// Raised when the ViewModel property is changed.
    /// </summary>
    public event PropertyChangedEventHandler PropertyChanged;

    /// <summary>
    /// Notifies subscribers about changing property or properties. 
    /// </summary>
    /// <param name="propertyName">Changed property name(s).</param>
    protected void NotifyPropertyChanged(params string[] propertyName)
    {
        foreach (string pn in propertyName)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(pn));
        }
    }

    private readonly Dictionary<string, object> fieldsStorage = new Dictionary<string, object>();

    protected T GetValue<T>(string propertyName, T defaultValue = default)
    {
        if (!fieldsStorage.ContainsKey(propertyName))
        {
            fieldsStorage[propertyName] = defaultValue;
        }
        return (T)fieldsStorage[propertyName];
    }

    protected void SetValue(string propertyName, object value)
    {
        if (fieldsStorage.ContainsKey(propertyName) && Equals(fieldsStorage[propertyName], value))
        {
            return;
        }

        fieldsStorage[propertyName] = value;
        NotifyPropertyChanged(propertyName);
    }
}

And "Speciality" property looks like this.

public string Speciality
{
    get => GetValue<string>(nameof(Speciality));
    set => SetValue(nameof(Speciality), value);
}

The problem: interface doesn't update when Speciality property changed

How to delete rows from DataGrid when SelectionUnit="Cell" in the GUI

I have a DataGrid that has SelecitonUnit set to "Cell" and I really cannot figure out how to delete a whole row. Normally I would just select row and press delete button(like I do in my other datagrid with default SelectionUnit) but it doesn't work like that. I tried implementing my own delete functionality but there has to be a better solution.

The DataGrid

<DataGrid Name="XdataBom" IsReadOnly="False" CanUserAddRows="True" CanUserDeleteRows="True" AutoGenerateColumns="False" SelectionUnit="Cell" Height="1080" Width="1920" VerticalAlignment="Top" KeyDown="XdataBom_OnKeyDown">
           <DataGrid.Columns>
                <DataGridTextColumn Header="Montować" Binding="{Binding Montowac, UpdateSourceTrigger=PropertyChanged}"/>
                <DataGridTextColumn Header="Ilość" Binding="{Binding Ilosc, UpdateSourceTrigger=PropertyChanged}"/>
                <DataGridTextColumn Header="Desygnator" Binding="{Binding Desygnator, UpdateSourceTrigger=PropertyChanged}"/>
                <DataGridTextColumn Header="Typ montażu" Binding="{Binding Typ, UpdateSourceTrigger=PropertyChanged}"/>
                <DataGridTextColumn Header="Obudowa" Binding="{Binding Obudowa, UpdateSourceTrigger=PropertyChanged}"/>
                <DataGridTextColumn Header="Wartość" Binding="{Binding Wartosc, UpdateSourceTrigger=PropertyChanged}"/>
            </DataGrid.Columns>
       </DataGrid>

There's a KeyDown event that handles pasting into the grid but I didn't override the delete key in any way.

DataGrid Column that contains Dropdown menu

I'm working on creating a table using Blazorise DataGrid, however I can't seem to get the options button at the end to work. I want to create 4 columns; Name, Description, Last Updated, and then the last column to contain a dropdown menu of Edit, Duplicate and Delete. I have written functions for the Edit, Duplicate and Delete, however I want it to show an Ellipsis, which will then be clicked to display the dropdown menu.
