.net - Check If A Radiobutton Is Checked In A Group?

Aug 11, 2010

I have group of radio buttons, each group ranges from 5 - 27 radiobuttons. And if any radio button in a group is checked I store 1 in db else I store 0. Now I'm checking each radiobutton using if loop to see if they are checked and set database value. I'm also trying to use the code below. Is there a good/better approach to check if they are checked or not?

Current code:

'rname is radiobutton prefix for a given group
'cnt is number of radiobuttons in the group

Private Function RadioIsChecked(ByVal rname As String, ByVal cnt As Integer) As Integer[code]....

Note: I cannot use radio button list. I know this can be achieved easily using this but i want to get solution for radiobutton

Asp.net - Select Case On Radiobutton Group?

Jul 30, 2010

I have say 4 asp.net radiobuttons which are grouped, I want to find out which one is checked.

What seems natural to do is:

Select Case RadioButton.Checked = True
Case myRadioButton1
Case myRadioButton2
Case myRadioButton3
Case Else
End Select

I just get a 'reference to a non-shared member reference' error. It's a shame because it seems such a clean way to do this test.. Is it possible??

ElseIf Radio2.Checked Then

Tabstop Not Working When Setting Radiobutton.checked To False

Feb 25, 2011

I have a form that has 13 groupboxes each with 6 radio buttons in them. I want to be able to tab through the left-most radio button in order. At load time, the left-most radiobutton in the top groupbox is checked. The only way I found to have this load unchecked is by setting it using a timer, but this makes it so that that radiobutton can't be tabbed to at all.

.net - Make A Class Property Behave Like The Checked Property On RadioButton?

Jun 1, 2012

I have a very simple class that holds a few public properties - ID, Text, Colour, etc. and a Boolean called 'SelectedItem'. Just like the Checked property on RadioButtons, only one item can have its SelectedItem property set to True within a particular group. Note: there will be several separate groups (lists), each allowed to have only one item with SelectedItem = True.

My first thought was that I would probably just have to handle everything outside of the class, setting SelectedItem to False for every other item in a particular list when another item was selected. But that seems rather inelegant to me. So I've been trying to think of how this might be done within the class. For example: could I perhaps have a private string property called say "GroupName" - set in the New sub when adding a new instance of the class - and then use a private shared method to set every item's SelectedItem property to False, provided the item has the same GroupName as the newly selected item? I would have a go at doing this but I have no idea how to enumerate every instance of a class from within that class, or whether that's even possible. Is it? Or is there another (better) way to achieve my goal? Here is a cut-down version of what I've got so far:

Public Class ResourceItem
Public ID As Integer
Public Text As String[code]....

As can be seen: instead of instantiating a new ResourceItem and passing that as an argument to the manager's Add procedure, I'm simply passing the details of the new item and the procedure is creating the item from those. I don't know whether this is a good or bad idea - please advise - but I've done it because I couldn't figure out how to make the SelectedItem property only writeable by the manager, so I wanted to avoid having directly accessible objects that could have their SelectedItem property set to True without it deselecting all the other items in the same group. Of course that still leaves the possibility of setting a variable to one of the manager's list items and setting it from there, so I would still like to know how I could prevent that, if possible.

UPDATE: I didn't use the code above in the end, deciding instead to go with Cyborgx37's solution - which seems to work perfectly well for me despite the warnings about best practice. I also realised I would need to use the same class in another scenario where multiple items could be selected, so it was easy to add a Boolean property to the manager to enable that.

VS 2008 Validate A Groupbox To Make Sure Radiobutton Is Checked - VB 2008

May 12, 2010

Is there a way to validate a groupbox with a couple radiobuttons in it to make sure that one of the radiobuttons is selected?

Heres why I need this. I need a user to be able to select their class rank out by way of radiobuttons in a groupbox. When they click submit, I need to validate that atleast one of the radiobuttons got selected and if not display a messagebox.

I got one reply early of:

If myGroupBox.Controls.OfType(Of RadioButton).Count(Function(rb) rb.Checked) = 0 Then
'There is no RadioButton checked in myGroupBox.
End If

Is there any other ways other then that? Preferrably a more 'dumbed' down way? This is for just an entry level VB class, I would prefer not to use something of that nature if there is another way.

VS 2005 Check Grid Items If Checked ListBox Items Checked?

Aug 21, 2009

Why is this code having the opposite effect? If It's checked in the checkedlistbox it's not check in my view, if it's not check in my checkedlistbox it is checked in the grid.

EDIT: More specifically. The CheckState.Checked is always the opposite. .Checked means it's not checked.

Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles CheckedListBox1.ItemCheck

Checked List Box - Delayed Check?

May 11, 2009

I'm having a hard time figuring out why this is happening. When I check an item in the listbox it calls the sub ItemCheck for the listbox accordingly:

Code:
Private Sub chklbToDo_ItemCheck(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemCheckEventArgs) Handles chklbToDo.ItemCheck
Dim iLoop As Integer
Dim iCheck As Boolean

[code]....

I've had to work with the delay of the check by reversing the boolean value caused by the check. But when I worked it into the program to delete the item that is checked, it deletes the selected/(un)checked item and THEN checks the item with the index. So in other words, if a user selects and checks an item in the listbox, and chooses to delete the item, it deletes the item and then checks the item that replaces it in the index (the following item).I don't understand why the checked value doesn't appear until after the sub ends.
