Listbox Topindex Changes Itself When Item Changed

May 19, 2012

When I have a listbox full of items and scrolled such that topindex is not zero/first item, changing the value of the top item causes the list to scroll up by one.I can compensate for that easily by changing topindex after the listbox1.items(index)=value statement, but does anyone know why it happens or if there is some property I'm overlooking?

Bound ListBox Item Count Changed Event

Feb 22, 2011

I'm using a textbox to supply a filter for the datasouce which is bound to a listbox. It works (mostly) with a few exceptions, one being i was to restrict the height of the listbox to the number of entries (upto a maximum number), so a bit like a combobox (which in effect is what I'm writing). One of the problems is when the number of entries changes there does not seem to be an event raised, although the OnDrawItem is called for the items to be displayed (the displayed ones!) Is there anyway to find out (in a derived listbox) when the number of entries has changed in the datasource?

How To Check If Listview Item Was Changed

May 7, 2012

I have a window which has 8 items in a listview along with 2 radio buttons below the listview. The user is able to select one or more selections in the listview and turn the selection on or off with the radio buttons(live, prior to hitting the submit button), my question is how do I tell which selection was changed? I was going to put the one or more selections into a string/array and use that later for some messages once the user hits the submit button. I can almost think of it but can't quite get there, i'll be using an if/else with the .selected option in listview items but am not sure how to tell if the user, say,goes back and changes the option from On to Off(Off originally)to remove that option from the array.

Add A Text Changed Method To Listview Item?

Feb 5, 2009

im trying to add a text changed method to my listview item. all the items are dynamicly created so i would think id have to use an addhandler listviewitem1.textChanged addressof listviewitems_click where listviewitems_click is the generic sub to handle the click. but the listviewitem control doesnt have a text changed event, but you can rename the text in the control anyway.

C# - Tab Data Lost On Selected Item Changed MVVM?

Mar 23, 2012

I have been trying to do this for ages and having no joy whatsoever.

I have a ribbon window of the following hierarchy:

MainWindow
MainContent (Tab Control)
TabContainerViewModel
ViewModelBase

View model base has an ObservableCollection of tabs type ViewModelBase. The Tab Control itself is binding fine to these, displaying appropriate view models. I have 2 problems however, I want a "NotepadView" (Of type viewmodelbase) to be replicated numerous times (one view many view models).

At the minute, I have 4 views (NotePadViewModelx where x is 1-4) with corresponding viewmodels, this is because each view had the same text per tab. Now I have individual views per tab.

When I type into tab 1 and switch to tab 2, I lose what I typed in tab one when I click back.

Oct 13, 2011

How someone would select an item from a list box and click a button and have that item go into another listbox with it's price? I seem to be stuck on this part.

Here's my code:

I want to select the first option from the first listbox and I want to put it into another listbox along with the price of that item on the same line in the listbox. I can't seem to figure out how to that.

Public Class Form1
Const dcmPRICE_STRESS As Decimal = CDec(595.0)
Const dcmPRICE_TIME_MANAGMENT As Decimal = 695

VB 2008 .suo File Needs To Be Changed/recreated Because A Path Has Changed. All Other Files Are OK

May 5, 2012

I changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"

VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.

The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'

Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.

I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?

Saving Changed Data Before DataViewGrid Selection (Row) Changed?

Jan 20, 2010

on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?

Get The Value Of An Item In A ListBox?

Feb 20, 2010

I was wondering how do i get a value of an item in my list view to be displayed in a text box without having to select the item in the list view?

In my list box i just have one number and this number changes depending what page the user is on so it could be 1, 2 or 3. What is the vb code to actually get whatever it says in the list box and store it as a variable so i can show it in a text box? I thought it would have been something like:

Code

Dim instance As String
instance = ListBox1.Items.ToString()
txtRoomID.Text = instance

There is only 1 item in my listbox i just want to get this item and display it in a text box.
