Radio Buttons...????

Hi all,
I am developing an app. in Vb .net that has a form with a no. of radio buttons. Much like a multiple choice Questionaire(4 choices for each question).
Once the user selects the options, and clicks on save, I need to write them in An excel sheet.
Vb6 had control arrays which made this simple, but Vb .net ..... I don't know how to do this.
Pl. help.

VB.Net has an equivelent of control arrays but you must set up the events that you wish to handle multiple controls yourself.
In the Sample below, I created a new project and added 4 option buttons. To handle all the option buttons in the same events, I altered the Button1_CheckChanged Sub to include buttons 2,3 and 4.
I doubled clicked RadioButton1 and was presented the following

Code:

---

Private Sub RadioButton1_CheckedChanged(Byval sender as System.Object,_
              Byval e as System.EventArgs) _
              Handles RadioButton1.CheckedChanged
'
I changed that statement to read
'
Private Sub RadioButton1_CheckedChanged(Byval sender as System.Object,_
              Byval e as System.EventArgs) _
              Handles RadioButton1.CheckedChanged,  _
                          RadioButton2_CheckedChanged, _
                          RadioButton3_CheckedChanged, _
                          RadioButton4_CheckedChanged

There may be a better way, but the big book I am reading on VB.net says this is the only way to manage "control arrays" in VB.Net

That's what my book says also.....

However, I am running into an issue where I have 8 list boxes with the same information (The user can choose 8 out of 30 items to graph). There are 8 labels to the left of these list boxes that I set colors to.

In .NET it seems like I have to do
lblItem1.BackColor =
lblItem2.BackColor =
...
lblItem8.BackColor =

as opposed to either using a control array in vb6 or even

For intI = 1 to 8
me.controls("lblItem" & intI).BackColor
next

So my question is: Is there a way to do the control looping? It seems like the controls are based upon integers as opposed to putting the name in.

WEll, I've found out a way to do this...
along with the handles on clicks, we can loop the controls by their tab index. This is much like doing...
arr(0) = "something"
arr(1) = something else"
....
....
...
arr(20) = "more"

here's how to do it.
radiobutton1.tabindex =1
radiobutton2.tabindex = 2
....

Now we can incorporate them by using a "for each" loop.
somewhat like this.....

ctrl = New Object()
control = New System.Windows.Forms.RadioButton()
Dim ctl As System.Windows.Forms.RadioButton
ctl = New System.Windows.Forms.RadioButton()
For Each ctrl In Me.Panel1.Controls
For Each control In ctrl.controls
If control.GetType Is ctl.GetType Then
If control.checked = True Then
Call showdetails(control)
'MsgBox(control.name)
End If
End If
' MsgBox(control.name)
Next control
Next ctrl

Now here I have a panel which have some 10 groupboxes.
Each groupbox has one label and four radiobuttons.
then, in the loop I call a function 'showdetails' which is somewhat like this....

Public Sub showdetails(ByVal sender As System.Object)
'Dim buttonControl As RadioButton = buttonControl
Select Case (sender.TabIndex)
Case 1
' MessageBox.Show(buttonControl.TabIndex)
array(0) = 1
Case 2
' MessageBox.Show(buttonControl.TabIndex)
array(0) = 2
Case 3
' MessageBox.Show(buttonControl.TabIndex)
array(0) = 3
Case 4
array(0) = 4
Case 5
array(1) = 1
Case 6
array(1) = 2
Case 7
array(1) = 3
Case 8
....
..
end select

I hope this clears every one's doubts. It did clear mine..
Thnks for the help.

The only problem with using the tab index is that it also is the ORDER in which the user goes through the screen. I guess it would work if those were the only controls the user went through, however if they are halfway down your form, wouldn't that be a problem?

Hi...
I guess its the same as "you win some you loose some".
Is there any other way out??
I couldn't find anything else.
:rolleyes:
