I have a record Pitch (see below)

    [TypeConverter(typeof(PitchTypeConverter))]
    public sealed record Pitch(double MinValue, double MaxValue) : IParsable<Pitch>
    {
        public static readonly Pitch Empty = new(0, 0);

        public static Pitch Parse(string s, IFormatProvider provider) 
            => throw new NotImplementedException();
        public static bool TryParse([NotNullWhen(true)] string s, IFormatProvider provider, [MaybeNullWhen(false)] out Pitch result) 
            => throw new NotImplementedException();

        public override string ToString()
            => $"{MinValue}-{MaxValue}";
    }

As you can see , I also have a TypeConverter (currently not fully implemented, but to show the problem it is sufficient).

  public sealed class PitchTypeConverter : TypeConverter
    {
        public override bool CanConvertFrom(ITypeDescriptorContext context, Type sourceType) 
            => base.CanConvertFrom(context, sourceType);

        public override bool CanConvertTo(ITypeDescriptorContext context, [NotNullWhen(true)] Type destinationType)
            => destinationType == typeof(string);

        public override object ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, object value) 
            => base.ConvertFrom(context, culture, value);

        public override object ConvertTo(ITypeDescriptorContext context, CultureInfo culture, object value, Type destinationType)
            => value?.ToString() ?? Pitch.Empty.ToString();

        public override object CreateInstance(ITypeDescriptorContext context, IDictionary propertyValues) 
            => base.CreateInstance(context, propertyValues);

        public override bool GetCreateInstanceSupported(ITypeDescriptorContext context) 
            => base.GetCreateInstanceSupported(context);

        public override bool IsValid(ITypeDescriptorContext context, object value) 
            => base.IsValid(context, value);

        public override PropertyDescriptorCollection GetProperties(ITypeDescriptorContext context, object value, Attribute[] attributes) 
            => base.GetProperties(context, value, attributes);

        public override bool GetPropertiesSupported(ITypeDescriptorContext context) 
            => base.GetPropertiesSupported(context);

        public override StandardValuesCollection GetStandardValues(ITypeDescriptorContext context) 
            => base.GetStandardValues(context);

        public override bool GetStandardValuesExclusive(ITypeDescriptorContext context) 
            => base.GetStandardValuesExclusive(context);

        public override bool GetStandardValuesSupported(ITypeDescriptorContext context) 
            => base.GetStandardValuesSupported(context);
    }

The Pitch lives inside a ViewModel and is correctly displayed in the RadPropertyGrid, so in that sense everthing works fine.

    [Category("Conditions")]
        [Description("Sets the minimum/maximum allowed pitch limit.")]
        public Pitch PitchLimit
        {
            get => GetProperty(Pitch.Empty);
            set => SetProperty(value);
        }

        [Category("Conditions")]
        public bool RequiresDE
        {
            get => GetProperty<bool>();
            set => SetProperty(value);
        }

when I now edit values in the RadPropertyGrid, the RequiresDE works when pressing enter or selecting the checkbox. It doesn't work however when I edit the value for the Pitch property. I can see that the SetProperty for RequiresDE is called, but when editing the PitchLimit the SetProperty is not called.

I honestly out of ideas to find out why the RequiresDE is called and the PitchLimit isn't.

Any help is appreciated.

Thanks

Hi,

Does anyone know how I can set the text manually in a RadPropertyGrid and a ComboBox? Or also the selectedIndex?
I want to manually set ONLY this one element.

Hi Team,

I need to stop refreshing once the filter is applied.

Example.I have lot of items in one panel ,If I selected item1 in that panel and applied filter in the RadPropertyGrid  for some fields.

And then I will select sencond item in the grid.Now,the RadPropertyGrid  should display the filtered fields but it showing entire fileds.

How to achieve this.

Or give me a solution to set the text for the searchasyoutype textbox from codebehind

I created a class with CommunityToolkit.Mvvm package and use ObservableProperty to create properties for this class. But the PropertyGrid  control does not recognize properties created in this way. Are there any way PropertyGrid  can support ObservableProperty?

using CommunityToolkit.Mvvm.ComponentModel;
using System.ComponentModel.DataAnnotations;

namespace Test
{
    public partial class DrawingModel : ObservableObject
    {
        public string Name { get; set; }

        [ObservableProperty]
        public double _length;


        [ObservableProperty]
        public double _width;

        [ObservableProperty]
        public double _height;
    }
}

[edit: I meant "Modal" Editor and not "Model" editor in the title but I can't update]

Hi,

as I know you can use a custom modal editor with an Editor attribute that is declared on a property. Is it possible to use a modal editor with a programmatic approach with PropertyDefinition? I have a dynamic class where I do not have the possibility to declare attributes on properties. On the PropertyDefinition class there is an EditorTemplate property. I managed to use this. But only "in cell" and not modal. Is that possible?

Best regards,

Oliver

Hi

I have a RadPropertyGrid, being defined as:

       <telerik:RadPropertyGrid Item="{Binding ObjectBound, Mode=OneWay}" Width="300" Name="propertyGrid2"
                                 Grid.Column="1"
                                 VerticalAlignment="Stretch"
                                 VerticalContentAlignment="Stretch"
                                 NestedPropertiesVisibility="Visible"
                                 AutoGeneratePropertyDefinitions="True"
                                 SelectionMode="Multiple"
                                 PropertySetMode="Intersection"
                                 telerik:PropertySet.ShouldAddNullForNonMatchingValues="True"

where I would like to bind 0...n items

Let's say all of those items belong to the class Car

  public class CarEngine
    {
        public int PowerKW { get; set; }
        public int DisplacementCCM { get; set; }

    }
    public class Car
    {
        public Car()
        {
            Engine = new ();
        }
        public string Manufacturer { get; set; }
        public string Color { get; set; }
        public CarEngine Engine { get; set; }

    }

In the code behind I have a property to bind to the PropertyGrid

public object ObjectBound
        {
            get;
            set;
        }

and will create the items like this:

  Car c = new Car();
            c.Manufacturer = "Honda";
            c.Engine.PowerKW = 110;
            c.Engine.DisplacementCCM = 1799;
            c.Color = "black";


            Car c2 = new Car();
            c2.Manufacturer = "BMW";
            c2.Engine.DisplacementCCM = 2199;
            c2.Engine.PowerKW = 150;
            c2.Color = "black";

            List<Car> list = new();
            list.Add(c);
            list.Add(c2);

now first, I will bind just one car instance to the RadPropertyGrid:

            this.ObjectBound = c;

Here I can expand the nested engine instance and can write to each field which is absolutety perfect!

Then we have a second use case where I would like to bind to the list with two cars and get their common attributes while differerent properties will be displayed empty:

      this.ObjectBound = list;

Therefore I had choosen "Intersection" for the propertysetmode of the RadPropertyGrid

For the primitive Attributes Color (shared between both cars) and Manufacturer (different) that will work just fine. 

But as one can see the nested Attribute "Engine" cannot be set as it not able to be expanded! I'd like to set e.g. a common displacement for both of the two cars. How can I realize such a behaviour as it is required from business?

thanks!

Hi,

I have a window that has a RadPropertyGrid and UserControl that contains five buttons. I want to make the screen full while clicking on maximize button. Now as I have fixed height and width. Maximize button is not working. Can you please help me out.
