[2005] Group Box and Radion Buttons

I have radio buttons grouped in a group box


Question1: Can I give each radio button a default value:

Example radio1 value = 1 ,radio2 value =2

If this is possible , How do I get which radio button is selected and what is it's value without using If statement.

Example : Messagebox.show ---> groupBox Selected radio button Value !

You can do this with the RadioButton's Tag Property

You can then loop through the controls in the Groupbox to see which one is checked

Code:

---

        Dim selectedValue As Integer
        For Each ctl As Control In Me.GroupBox1.Controls
            If TypeOf (ctl) Is RadioButton Then
                If DirectCast(ctl, RadioButton).Checked Then
                    selectedValue = ctl.Tag
                    Exit For
                End If
            End If
        Next

---

Another way to do it would be to have a routine that handles the check changed event of the radio buttons. Put the value of each radio button that you want them to have in their Tag property and then just have something like this:

vb Code:

'Declare variables
Dim RadioValue As String
Dim RadioName As String
 
Private Sub GetButtonValue_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) _
    Handles RadioButton1.CheckedChanged, RadioButton2.CheckedChanged, RadioButton3.CheckedChanged
        'Assign variables the values and use these
        RadioName = DirectCast(sender, RadioButton).Name
        RadioValue = DirectCast(sender, RadioButton).Tag.ToString
 
End Sub
