Hi
It makes me crazy but I am working on this about one week and I could not achieved.
I have a class and this class has lots of boolean.

Ex: public bool1,
public bool2 etc.

Now I want to create a custom radio button with custom property.
In this custom property area I will chose one of the boolean of my class from dropdown list. After that If boolean is true, radio button will be checked.

I work on WindowsForm.
How can I do that?

What I have tried:

Were you planning on telling us which of the many UI frameworks you're using?
(Windows Forms, WPF, ASP.NET WebForms, ASP.NET MVC, ASP.NET Core, Xamarin, etc.)

They all have their own version of a RadioButton, and the process for writing a custom control will be totally different for each.

Oh so sorry. I work on WindowsForm and using VisualStudio.

"I need an example code for this", gimme code is not a question. What I think you want to do from your convoluted description is called data binding.

How can I do that?
Is it a question? I said that I worked on this for one week. If I have a clue about how can it be, I would ask about this.

I don't understood your requirement.
Perhaps you should explain your control (that you want to create), it's property (or properties) and what should happen with them.
Also a Screenshot or some more code could be useful.
I'm very familiar with customizing controls but with your description I don't know what to do ...

What I can see is a RadioButton on a form.
There is no difference to the Standard-RadioButton.
But I asked you also to explain your requirement.
What I have seen :
you have a Property called PLC-Var - do you want to created a .Net based HMI ? To which PLC you want to connect ?
To get a step ahead it is important that you answer each question as complete as possible ...

Yes there is no difference on visualization. I have lots signal to display and I want to do this with radio buttons. My signals is boolean and I read them from an OPC server (KEPWARE). Now I want to relate a radio button and a signal with one click. So I want to add a custom property to radiobutton. Yes I want to make .NET HMI for siemens S7300 - S71500 and beckhoff PLCs.

So you want to create a UserControl with more than one RadioButton on it.
Each RadioButton should correspond to a Property of your UserControl ?

To connect the PLC you need to assign the VariableName inside the PLC to your RadioButton. This normally comes with a kind of Itemserver which give you a Notification (an Event) that informs you that the related Variable has changed it's value.
But I don't know your OPC-Server ... :( does it support all 3 PLC-Types ? I hope you know that S7-300 is different to S7-1500 (TIA) and both are complete different to Beckhoff-PLC (ADS-Communication).

First I read all variables from PLC with C# variables. So communication method is not important. I use Kepware and ADS communication. I can do them. But I need help displaying them simply. There are lots of boolean signal on C# and I want to display their status with radioButtons seperately. Every signal will has it's own radiobutton. So there will be only one radiobutton on my custom control. And I will relate it with a boolean by using propety area. For example there is a boolean on C# which is called "bAirPressureIsOK". It refresh its status on every read from PLC. Everything is ok here. Now I want to relate it with a radio button on visualstudio designtime. I will drag and drop a radiobutton to my form and choose "bAirPressureIsOK" boolean from dropdown list. This dropdown list will show the all booleans as an option to me.

I understand your requirement because I'm also working in the Automation.
But you must think over your way to go.
Now you have a method (I think) which does the communication with the PLC and reads all the necessary variables into your Application to have them all as C#-Variables. But this doesn't Change anything onto your Screen because there is no existing Connection between your controls (for examble the radiobutton) and the variables. What you now can do is : you know the Control which should display the state or value from the variable and inside your PLC_Read-method you assign those controls the matching values. This is a way which could be done ... but that is not a good way. Better is : your create a connection between the variable and the control. In this case the variable automaticly manipulate the control to show it's value. This work normally is done by Events ... and you need a List in which each active control is registered and also the variable it needs to use. This method I called "Item-Server".
If you want to go this way (I think this is the only one which is practicable) I could try to help you ...
But ... at first you must realize how .Net (and also controls) works ...

Of course you have to implement its own Checked/Unchecked Boolean Property in a custom Control, in this case a RadioButton. But the Checked Property must be implemented inside your custom UserControl not on different class.
You then can choose to use a Radibutton within your MyRadiButton control that derives from UserControl or you would do it using System.Drawing methods to paint a circle and draw text indicating the Text Property. This all is too difficult for a novice but you may find an example on Web.

Here is some code to start with:

VB.NET

Public Class MyRadioButton : Inherits UserControl

Private _Checked As Boolean
Property Checked As Boolean
 Get : Return _Checked : End Get
 Set(value As Boolean) 
   _Checked = value 
   EnableDisable(New PaintEventArgs(Me.CreateGraphics)) 
 End Set
End Property


Sub New()
  '//
End Sub

Protected Sub EnableDisable(e As PaintEventArgs)
   If Checked Then
    'e.graphics.fillellipse(draw/fill a circle)
   Else
    'e.graphics.drawellipse(draw circle)
   End If
   'e.graphics.drawstring(draw string of Me.Text Property)
End Sub

Protected Overrides Sub OnPaint(e As PaintEventArgs)
    EnableDisable(e)
End Sub
End Class
