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.
View 6 RepliesI have problem, that I have a lot of code, and I want to try to make less as much code. I have 30 RadioButtons and is even possible tu use something like that
If CheckedRadioButton.Checked = True Then
When user click on any of RadioButtons, then it can write number of RadioButton in settings.
I have two radiobuttons and i want to save the result of the one that has been chosen into the databasehow do i go about this.as for now i have been using an if statement as shown below but i know that there is a more educated way to go about it.
If rdbCustomSW.Checked = True Then
txtType.Text = "Custom"
End If

View 4 RepliesI 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 GridView with a load of data in, there is an ID associated to the data that I would not like to be visible to the users. All worked fine when all the cells were visible, but as soon as I change the ID DataBound column to false, when I try to access the item in code I get "" instead of it's actual value (that worked perfectly when it was visible).
Is there a reason for this? If not, how should I be approaching this?
Can someone clarify if there is ever a need for the below?
When setting a textbox "Visible" property to False is there any reason why I should also set the "Enabled" property to false.
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.
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.
Dim lv As Integer
For lv = 1 To 33

I want to have a text file perhaps a ini file where I want to set a value to either True or False so a boolean. How can I do something like this. I want it to be a in text file so I can change.

To recreate this behaviour, you need to create a pop-up form with the following properties:
(1) ShowInTaskBar = False
(2) Display the form with the Show method and loop until the form is not Visible.
(3) In order to close the form when the mouse is clicked out of it, override OnDeactivate, and set visible to False.
Next, create another form that will display the pop-up when a button is clicked:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As Syste
Using pop As New PopUp
pop.Visible = True
[code]....
it also puts a black border around the form. (You'll have to set FormBorderStyle = System.Windows.Forms.FormBorderStyle.None to see this.)what this style does apart from putting the black border round the form?

I have a DataGridView control with 10 columns, some columns that are just informational, populated by my visual basic program. The user is not supposed to be able to change the data in these columns, or even tab or mouse to them. I can set the column ReadOnly property, but the tab and mouse still allow that column to be selected. The last five columns of the grid need to be disabled from tabbing. For example I have 10 columns. When user tabs thru grid to the fifth column I want the focus to go next row, second column.

View 1 RepliesIn my keydown event handler, I am trapping when an ENTER is pressed and i want to advance to the next tab stop as is it was a TAB presses.I am currently using "SendKeys("{TAB"})" and this works but it is a sloppy way to do buisness, as there may be some typeahead keystrokes in the keyboard buffer.
I have also tried going through the controls collection off the form object, but it is too complicated as i am using containers within containers.Another consideration that TAB processing must be taking into consideration is "what if the tabindex is equal to the current tab stop? what if the next tab stop has tabstop=FALSE or is not enabled or not visible.The sendkeys approach handles all these issues but is a dirty approach and has keyboard buffer event processing quirks.There must be a method off some object somewhere that simply moves the focus to the next tabstop candidate.

project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
