Question
VB.NET: how to list all radiobuttons inside of Groupbox
Hi X-perts,
I need to list all the radiobuttons inside of a groupbox and return a tag value of the checked one.
How can I do this?
I cannot use
For Each ctl As Control In Me.GroupBox1
because GroupBox in not a collection type. I don't want to loop through ALL controls in the form, but only through a GroupBox.
Please, advise.
Thanks

If you have VB.Net 2008 then you can use the Controls.OfType() to shorten the code slightly:
(still the same basic approach as __Vortex__)
For Each rb As RadioButton In Me.GroupBox1.Controls.OfTy
If rb.Checked Then
Debug.Print(rb.Name & ": " & rb.Text)
Exit For
End If
Next
Or you could use LINQ to get the selected Item:
Dim selected = (From rb In Me.GroupBox1.Controls.OfTy
If Not IsNothing(selected) Then
MessageBox.Show(selected.N
Else
MessageBox.Show("No Selection")
End If
