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.

I wonder how to make the Radiobutton ON when webbrowser is fully loaded, and the Radiobutton OFF when the page is loading. It's like boolen. Im using Webbrowser1.If you do not understand im mean this:
1. Click on a link on a site.
2. The Radiobutton gone OFF.
3. When the page is 100% loaded, the Radiobutton gone ON.

Then how click a button, and I want a message box to pop up saying "You have purchased # (whatever item)(s)" The radiobutton text has the name of the item.

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.

I am working on a project that has a groupbox with 4 radiobuttons in it. Since I have it in a groupbox, instead of doing an if statement for each radiobutton, can I do something else that will give me the value of that radiobutton so I can insert it into an sqlcommand line?This form has three groupboxes. the other two groupboxes are just textboxes so I was able to get the value for that and do an insert into statement to put the values in my database.How can I do the same with a groupbox that has these 4

I have a (checked) listview with values in the subitems. I am trying to make a simple sum of the checked values, but I can't seem to get it to work. The values returned aren't correct.
The idea is that each time I check or uncheck a row it re-calculates the values from subitems(2).
Here's what I was trying:
vb.net
For i = 0 to Listview1.CheckedItems.Count - 1 Label1.Text = CDec(Listview1.CheckedItems(i).Subitems(2).text) + cdec(Listview1.CheckedItems(i).Subitems(2).text)Next i
I have (text) values like 77.50, 115.60, etc.

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

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.

I have a lot of radio buttons in a groupbox. Normally I will check each radio button individually using If radiobutton1.Checked = True Then.
But I think maybe there is smart way to check which radio button being checked in a groupbox.

I trying to get what I think should be a simple thing. I have a checked treeview. I need to get the text of each checked node into a string. For the life of me I can't get it. I am trying to loop thru all the nodes and see if they are checked but I keep getting a "object reference not set to an instance of an object" but I don't know why.
Dim value As String
Dim node As TreeNode
Dim i As Long

i have a form with a bunch of textbox's that are connected to a ms access data source, so i can update, edit and delete records.I also have 4 radio buttons.What i'm trying to acheive is that when a row is selected in the datagridview, the textboxes show the values in them (id, name, number, etc.),which works perfectly, and the radio buttons should show the value of the "grade" column of the cell that is selected.
So basicaly when you click a record, if the grade is 5 i want the radiobutton5 to be selected. And if i click radiobutton6 it should update the field to 6.

I am having a problem doing select case inside my groupbox.I have a bunch of buttons in a groupbox, each button will do a same function only with a different values when clicked.For example, let's say i have 3 buttons in the groupbox for now.[code]The function will display a message in a textbox.My problem here is, the message shown in the textbox will always be Case "C", the last 1. I jumbled the order, anything that's last will appear instead which I think it's because of the For Each. I tried a do while loop but I do not have any conditions i can think of to use for it. I also tried using IFs instead of Select Case but not successful.

I'd like to make a GroupBox have a black line as its boarders , just in the old VB6 , but it seems there isn't any such a property . Look , for example in the picture below : First there is GroupBox control but it can only have a line around it without color . Next , there is a Panel control , but the problem with that is that it can't have a caption set . At the far right side there is Panel control with a Label control placed over it . That's the best way I can think of in order to make something that at least will look like with what I have in mind . However , is there any other way I could do that ?

i have a list of links on a form and when you click one, it will set a specific groupx visible to true in a set position. So I have about 8 groupbopx control on this form. When I drag one out of the way and another in the form in design time, it seems they stay inside one another at times if they overlay. I don't understand this. Then some will not show at runtime depending where they arer left from design time even though I set the position to be in the form. This is completely different from vb6. Why are they staying inside other groupbox controls rather than being independent?

I have the following
Private Sub ClearAllEditableControlsInGroupBox(ByVal GB As GroupBox)
Dim myControl As Control
For Each myControl In GB.Controls
[Code]....
This code doesn't work because the strings returned in the select case block don't match any of the cases that are coded. I need a better way to do this, I imagine there is a more efficient way.
