Get Listbox Text Using Index Of Its Item?

Aug 19, 2010

In simple terms, I want to compare the value of a databound listbox display member with another string. However; I need to convert the listbox databound items to an array first as I may have to do 1,000's of comparisons on this.

I have a databound listbox from a sql server table that populates fine. I'm trying to retrieve the display value of a listbox item without selecting the item. My goal is to compare items in listbox1 with items in listbox2 and if item is in listbox1 matches an item I want to load into Listbox2, then I do not add the item to Listbox2. Listbox 2 is not databound but contents I'm loading come from a datatable.

So, I iterate through the items in listbox2's datatable but as I'm adding the items from the datatable to the listbox2, I check if the item exists in listbox1. The data that is being compared is the Displaymember of Listbox1 and a string value I want to manually load into listbox2.[code]....

This works exactly like I want it but the only issue is when it gets to the last item in the list it want play it.

Getting The Index Number Of Selected ComboBox Item?

Feb 6, 2010

I have a combo box setup with 4 items, with indexes ranging from 0 to 3.

Later in my code, I need to do a certain event depending on what is selected. To do this I thought about comparing what the index of the selected combo box item is, because integer comparison is faster than strings, right?

how I can grab the index of the selected value?

SelectedIndex : Gets Or Sets The Zero-based Index Of The Currently Selected Item In A ListBox?

Jun 7, 2012

First of all, I'm a somewhat-experienced VB3 Developer, and I'm trying to convert a VB3 app to VB.NET.I got the programming guide (http:url....) by searching the web.The problem I'm having is the syntax for .NET is way different than VB3, and that's OK, but finding the correct syntax is very difficult.I'm trying to eliminate duplicates in a ListBox:

When I access the Programing guide, I see that:

ListBox.SelectedIndex Property

Gets or sets the zero-based index of the currently selected item in a ListBox.I also have Murach's and Stephen's manuals, and they say the same thing.Visual Studio converted The old .ListIndex to a VB6 Function:

If VB6.GetItemString(PlayList_ListBox, I) = VB6.GetItemString(PlayList_ListBox, I + 1) Then

This is Try #1. It generates: VB6 is not declared. It may be inaccessible due to its protection level.Then I read that VB6 is only for converting old code.So then I tried SelectedIndex:

Dim I As Short [code]..........

Forms :: Find A Method Of Looping Through A Listbox And Retrieving The Index Number And Values?

Mar 24, 2010

I need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..

The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.

How To Get The ID Number Of A Selected Item In Listbox

Dec 13, 2011

I am trying to use a listbox to hold categories from one table in a database and by clicking on the categories in the listbox it will display data from another table in the database that is linked to those categories. One table has a field called ID and the other has categoryID and categoryID is linked to ID so it displays the numbers from ID.I am using this:

daSamples.SelectCommand.CommandText = "SELECT * FROM tblSamples WHERE tblSamples.categoryid =" & (lstCategory.SelectedIndex + 1)
daSamples.Fill(dsSamples, "tblSamples")

Currently, however with this if you delete a category from the table with ID in it then it changes the values of the selectedindex in the listbox which messes up the data that gets displayed. How can i change this so instead of using the selectedindex from the listbox, it takes the ID from the selectedindex?

Get Selected Item Index Or A Sorted & Grouped List Relative To Item Source?

Feb 12, 2011

I'm having some difficulty with a sorted & grouped listbox in WPF vb.net 3.5 that has an items source bound to an ObservableCollection.

What I want to be able to do is to retrieve a piece of data from the ObservableCollection items source depending on what item in the listbox the user has selected.I've almost got it working but because the listbox is sorted it does not match the index of the items source.

[code]...

As I previously mentioned, because the lstBox is sorted and also grouped the index's don't match up.Does anyone know how I can get the correct information I want from the List Source depending on the selected item in the list box?
