I have a list of cities in a list view (screencap attatched) what i am trying to do is find out which ones the user has checked, and also the sub item for each selection
for example is the user selects: London i can get the country values to which is UK.
my form contains a checked list box [data coming from the database] a combo box [bind to a database table product] and a listview [was previously a listbox]
[Code]...
In a listview with check boxes, there are two fields being loaded, ID and Lastname. With this information I want to get the ID of the person whose box is checked with this sub:
[Code]....
Is there a way to check whether or not the radio buttons within a group box have been checked? I have been able to check if one radio button is checked, but I would like to know if I can check for both within the same if statement, or if I would have to write a new one for the second radio button. Or can I just use the groupbox and check for selected radio buttons from that?
If Not rbMale.Checked Or Not rbFemale.Checked Then
ErrorProvider1.SetError(gbGender, "You must select your gender.")
Else
ErrorProvider1.SetError(gbGender, "")
End If
Not it still displays the error message if the female button is checked.
What would be the syntax to check inside a visual basic form panel for checkboxes and find which are checked? I understand how I Could use a for loop and an if statement, but I'm confused as to the syntax to check for each checkbox. for example:
Dim i As Integer
For i = 1 To 10
'Here is where my code would go.
'I could have ten checkboxes named in sequence (cb1, cb2, etc),
'but how could I put i inside the name to test each checkbox?
Next
Code:
Dim MainForm = Me.Controls.OfType(Of CheckBox)()
If Not MainForm.All(Function(cb) cb.Checked) Then
[code].....
How do I make an if statement that would check if the user has selected an option from the select list named cboGrade and also to check if the user has selected a radio button from the group named gbCalcType? I have an action that is carried out when a button is clicked, but before that action is carried out, I need to check the above.
I have this so far:
If rbPlus.Checked Or rbMinus.Checked Or rbMultiply.Checked Or rbDivide.Checked Then
instructions are here
End If
This checks that one of the radio buttons are selected. How do i check that an option is selected from the option list? There are three options: 3rd, 4th, and 5th. And the text starts out saying Select One and it locks the control once they choose one.
This is probably easy as well. But I have this listview which contains exe files I've listed up. Now, I want to execute these exe files in turn from which items are checked or not. So, I've tried this:
For each item in listView1.CheckedItems
Msgbox item.ToString
Next
Cause I noticed that the item in checkedItems doesn't contain much. And if I convert it to a string, it ends up in the msgbox looking like this: ListViewItem: {Filename.exe}
I'm all new to this treeview business. I have a fixed treeview, very simple and basic. Only two levels, parent and child nodes. I just need two things out of this treeview.
1) If parent is checked, check all child nodes.
2) If just one child node is unchecked, uncheck parent node.
That's it! I've been looking for this for 30 mins and I cant find it. Maybe because my vb.net is old, it doesnt seem to be the same as others =/ I'm using vb.net 2003.

View 5 RepliesI have an idea on how I want to proceed, but thought to get some ideas from you all first. I asked a similar question a while ago, but that involved different controls.I have 7 items in a ListView. If the user checks one of the items, I want a panel with three radio buttons to appear just for that item.I originally thought to make 7 panels, hide all of them, and then show and hide them when appropriate. I know this will work, but I really don't want to just overlap 7 panels and an overall 21 radio buttons.Is there a way I could use only three radio buttons with one panel? Or maybe create the controls during runtime?
View 3 RepliesI remember doing this in a checkboxlist element, but with listview element its giving a hard time.
Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, _
ByVal e As ItemCheckEventArgs) Handles ListView1.ItemCheck
If e.NewValue = CheckState.Checked Then
For index = 0 To Me.ListView1.Items.Count - 1
[Code]...
Is this only done in VB by making a custom control?

I have managed to get it to write a string to a textfile if the listviews checkbox is checked but i can not get it to write a particular string if it is unchecked.
'LOOP CHECKED ITEMS
For Each lstItem As ListViewItem In Me.ListView1.CheckedItems

How do i Iterate an unchecked item as the library doesn't have .UnCheckItems?
If its checked i need to add "true" to the string and if its unchecked i need to add "false" to a string that gets written to a textfile.
Have a populated listview with check boxes. If the item is checked I want to send it to report for printing. This code is bypassed:
Code:
Private Sub GetSelectedItems()
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Count is always = 0. This seems to work only if the item is double clicked. And then only one item is returned in the msgbox. MSDN says "The SelectedItems property will not contain any items if the property is accessed before the ListView handle is created, which typically occurs when ListView is initially loaded for display in the form. You can check to see if the handle is created with the IsHandleCreated property."
When I tried to check for the handle, an error said something about overloading. So I added this:
Code:
Public Overloads ReadOnly Property GetSelectdItems()
Get
If Not Me.ListView1.SelectedItems.Count = 0 Then
[code]....
Which does not help. How to find the items checked/create the needed handle?
I need to work on my listview. Do you know how I can convert the strings of checked from true to enabled and from false to disabled?

removing Listbox item from checked Listview item.The code I tried just errors out.

I've got a checked listbox on my form which saves the checked items to a spot in my database on the .ItemCheck event.But there's a problem, when I begin checking items, I check the box and click off it, but it doesn't save. (This is if I've only chosen one item)
If I choose two or more items it will save, but unchecking them takes a lot of clicking around to figure it out.Is there a better event that I can use? I've tried the SelectedIndexChanged and that has the same result, there's a lot of clicking around in the checkboxes to end up with the desired selected items, and it does not allow a single item.
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

Is there any better performance by checking for a true value like this:
