VS 2005 Write Listview Items Depending Upon Checkboxs Checked State?
Apr 30, 2009
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
Next
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.
I have added two checkbox controls chkBox1 and chkBox2. What I want to do is that when both the chkbox are same meaning checked or unchecked the label should be On and if both are not same label should be Off.
I have a Main form, called Main.vb, that is a Parent Form. I have another form called Notes.vb. Inside Main.vb I have a toolstrip with a button on it called Notes. I'm wanting to change the checked status of the Button to either True when the Notes.vb window is open inside the parent or to false when it is close. Is this possible?
I'm kicking my self for not being able to resolve this.I have a few items in my context menu thats for my listbox that toggle enable/disable depending on eitheritem is selecteditem is checked.the top 3 items should be enabled only if a item is selected, which works,and the bottom 2 only if an item is checked in the list.(it is a chked list)But what i would really like is that if ONE checkbox is checked then the top three would be disabled. i did try adding a for loop to check for an item is checked but it only half the time worked. (i added the code also)
vb ''' <summary> ''' Ensures the process manager context menu items reflect the selection/checked
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.

On the form that i have there is a listview with checkboxes enabled it all works fine but when i close and reopen the form all the previous checked checkboxes are uncheched . Is there a way to save the state of the checkboxes and on form load to restore them ?
I'm trying to program a personal project, but I've hit a bit of a bump in the road.I've got a Button, a Textbox, and a CheckedListBox; when the button is pressed, whatever is in the TextBox is added to the CheckedListBox. However, when the form is closed and reopened, all of the CheckedListBox's items are no longer present. My CheckedListBox's name in the code is ZapList.
Can someone assist me in, not only saving all of the CheckedListBox's items, but retaining whether or not they were checked as well as the order they were in? I've run out of hair to pull (figuratively) and I really don't want to quit this project, too much effort has gone into it and I'd hate to see it go unfinished like my numerous other projects. :icon_cry:
I want to use property bindings under application settings to store settings for my program. However I have run into a problem. For some reason the checked property is not binding to drop down menu item's checked state. The binding works for text boxes and other controls. I have tried to bind both using the checked property, and checked state property. Auto check on click for the menu items are set to true.
Anyone have any recommendations in getting the app-settings property binding to work without the need to manually set that info and manually run My.Settings.Save?
I am using ListView Control which CheckBoxes property of the control is set to true..when the from is loaded then all ordernos are loaded into the listview. when i select the orderno then enter contain of the selected orderno to displayed in datagridview control. now i want select 4 order nos and want to display all contain of 4 selected ordernos how find out which orderno is selected through loop and in which even i have to place.
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?
Example: That's 8 different combinations: 1, X, 1 1, X, X 1, 2, 1 1, 2, X X, X, 1 X, X, X X, X, 1 X, 2, X
Any way to get the different combinations depending on the Checked checkboxes into an ArrayList. One entry per possible combination (like the example above). Note this example is just for 3 games, I will have 13 games in my program so if you click all checkboxes thats 1,6M combinations. Is it really wise to have 1,6M entries in an Array? I also want to be able to set demands, like: delete all lines in the Array containing two X. Maybe an ArrayList isn't the way to go?
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]
I need to write a method in C# to save all rows in a given datatable back to the database, but I cannot depend on the rowstate of each row. I can't think of how best to do this without extensive looping through the database table data or constant database querying.
I want to essentially perform the following insert / update for each row in the datatable, but more efficiently:
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 have four textboxes that only accepts numeric data.On each box is a corresponding checkbox.I want to have a button that will get the total sum of all textboxes wherein their checkboxes are on checked state.
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:
I have got a problem with adding the listview items in the label, when I select the checkboxes in the listview I keep getting the same text to add in the label when one of the checkbox is ticked.
Private Sub listView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) For i As Integer = 0 To listView1.CheckedItems.Count - 1 If label3.Text = "" Then
I have a problem with the loops, I am trying to read for every items in the listview1 and I am trying to find the matches for every listview items in str.contains variable and extract every field id of delete.php for each matches. I can only get one match for the listview item. I want to find each listview items in str.contains variable and find for each matches then extract for the field ids.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If Button1.Enabled = True Then
I have a bit of problem right here. I am using the timer to connect to my site and extract the info that come from an html tags name, so when I closed the dialog and reopen, it filled the listview items as double.
Here's the
Private Sub form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load ListView1.Items.Clear()
I currently have a form with a listview. On another form, I would like get all the items from that listview. This I can achieve but I always get the "Cross-Thread operation not allowed exception" message. I've tried the following code to avail.
Let's say I have a checkbox1 control on form1. I then open form2. I want to be able to change the checked state of checkbox1 on form1 from form2.[code]...
I have a menu bar like this.I need to use them like radio buttons. So i have come up with this. Seems a nasty hack since it loops all my menu items. And if i later add different checks it would interfear.
vb Private Sub mnuMainMenuToolBarComposeExistingThread_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles mnuMainMenuToolBarPrivateMessage.Click,
I have a datagridview with checkboxes in the first column and I want to do a loop on saving the serialnumber(s) when the users decides to check a number of checkboxes Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code]...
the problem with this code is that it only inserts the serial number of the LAST checked checkbox and the number of entries of it depends on the number of checked checkbox for example ... if I checked the rows with the serialnumber 123 and 55652341, first the row with the serial number 123 then second 55652341, only 55652341 appears in the database and it is entered twice(twice because two checkboxes are checked)
In Vb.net 2005 how can i trap the checked/unchecked state of a datetimepicker through an event. I'm trying to execute two different methods based on the checked/unchecked state of a datetimepicker when the user clicks the datetimepicker. When the user checks the dtPicker Method A is executed, when the user unchecks it Method B is executed. How can i trap it.
I am trying to access the checked state of a CheckBox from a BackGroundWorker thread. I am utilizing properties and it seemed to work just fine. However, I'm using 10-15 CheckBoxes and I think using the InvokeRequired property would probably be best. I've looked over JMC's thread that talks about how to access controls from the worker thread a bunch of different times and I can't seem to grasp the concepts. When it comes to the InvokeRequired property, I suppose I understand why it is needed. But I'm not sure if I understand it completely.
From the example that JMC provides: vb.net Private Sub ResetTextBoxText() If Me.TextBox1.InvokeRequired Then Me.TextBox1.Invoke(New MethodInvoker(AddressOf ResetTextBoxText)) Else Me.TextBox1.ResetText() End If End Sub
If I'm not mistaken, this tells us that if invocation is required to access the control, then we access via the MethodInvoker if not, then we just access to directly? So, if I need to check the checked state of a check box, I know I can just put a conditional statement after the Else line if I can access it directly. But, if I can't how would I use MethodInvoker to check the checked state? And then, when calling it from the worker thread, would I just call the sub?
