VB.net -  GroupBox / Panel DataBinding and behavior

I am working on a throw-away application as a self-training tool to simply understand VS2015/VB.net. I am an expert with VBA and MsAccess since 1991.

In Access, the group box was pretty slick. You add as many radio buttons, buttons or checkboxes into the group control and each of the controls within the group control were assigned a value that was handled by the group control. The group control was bound to a table element for fetching and putting the data.

However, I learned that the VB.NET panel / groupbox only permits radio buttons for selection where only one radio button is true and any given moment and the others are false where checkboxes inside the groupbox/ panel do not behave that way. That's OK with me.

In my application, I have a panel control that has three radio buttons. I would like to store the value of the tag of the chosen RadioButton control into a data element in my table.

The questions:
1. Can a panel control be bound to a table element? In other words, can a groupbox or panel store data?
2. How does the binding take place? (e.g. FormControlName.DataBindings.Add(....)  )
3. How is the form populated so that the correct radio button is true when the record is fetched and displayed on the form?
3. Can you provide me with sample code so that I can mimic it in my throwaway application?

Thanks in advance!

No they are only visual items.

??

3. How is the form populated so that the correct radio button is true when the record is fetched and displayed on the form?

within your code you would use some sort of if/then approach to set the control's property to checked or unchecked

3. Can you provide me with sample code so that I can mimic it in my throwaway application?

Thanks, David!

This is not the "news" that I had hoped for! <grin>

The functionality of the option group in Access is something that hopefully the Visual Studio team could adopt and include in future releases. Or maybe, someone could create a custom control that offers that functionality.

I will write the necessary code.
