C# - Loop Through A Multi-column Listbox In WPF?

Oct 5, 2011

I have a listbox with two columns. Each listbox item contains a horizontal stacked panel which in turn contains textblocks.

The listbox is empty, with each listbox item being added by the end-user through a couple of textboxes placed elsewhere. The first column accepts strings, and the second column accepts only percentages.

(I have attached a relevant portion of the event sub where a user is adding new rows.)

Private Sub btnAddItem_Click(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles btnAddSplit.Click
Dim ListBoxItemName As New TextBlock


I would like to be able to check every time the above event is fired that the column of percentages does not exceed 100%. I have a couple of labels below the listbox itself where I would like to show the running total and the remainder.

My questions are:

1) How can I loop through the second column of percentages to show the running total and remainder?

2) Is there something more suitable than a ListBox that could make this easier?


Compare The Value Of Two/multi Column Array And Add Into Listbox Without Duplication In Visual Basic?

May 2, 2012

I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):

ID | Name | Type
1 | Cat | Animal
2 | Dog | Animal


This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:

Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)

Read all the elements in the list and pass through ReadArrayString.Split the string using:

DataString.Split(New Char() {";"c})

Pass through


Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:

If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then
End If

Now When you click TypeComboBox it will show drop down menu with following list only.


After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:

If Animal is selected/clicked from TypeComboBox then
Add Cat into listbox
Add Dog into listbox


I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.

VB 2010 List Box Multi Select Loop

Jan 24, 2012

i have having a annoying problem to do with loops.


When the user selects a few rows from my list box i want to run code on them selected items which i can do fine, but when the user only selects one of items and hits the button. it goes throught the loop first and gets the picture and all is fine its when it comes back to this function after there are no more items to perform tasks on. it increments index again and then falls over because its out of bounds of the array. i want it to stop after one loop but i also want it to be able to have the multiselect option still so the user has a choice.

Have No Multi-column Combo Box

Oct 29, 2009

First, I don't fully understand why VBA can have a multi column combobox but full VB doesn't? What purpose does it serve to only have a drop down list of text strings? I know there is an index property, but what if the items in the drop down can't logically be associated with an index value?

Anyways, here is my problem. I have an enumeration value that I want to add to a combobox. I have the code to go through and add the text of each enumeration value to a combobox. This is fine for enumerations whose values progress in order from 0-whatever. However, I have some enumerations whose values are, for example[code]...

Forms :: Multi Column Combobox (looking For Method)?

May 14, 2010

I'm using vs2008 with vb.net, and I have googled all around for a multi column combobox and I know there is not an easy way to do it in .net. However, this is my situation:I have a table in my database that only has around 4 or 5 entries, with the columns FirstName, LastName, Type. I need all of these columns for each of the 4 or 5 entries to be displayed in the combobox. I've been trying to think of simple ways to do it such as counting all the rows, selecting each cell in a loop and programmatically assigning them to the comboboxes, but I realized that the ID column for these entries have numbers that do not go chronologically. (I thought that if I counted the rows, the row number would correspond to the ID number and I could go about looping and assigning variables/concatenating them into the combobox, but this is not the case).

So I am just looking to see if anyone else has any ideas on what I can do to solve this? It's a pretty simple problem but I'm kinda out of any simple ideas.

Multi-character Searchable Listbox?

May 11, 2009

When I used to use Farpoint controls (w/VB6), there was an option on a listbox to set it to mulit-character search mode. It seems that VB.NET (at least 2005) doesn't have this capability.  If I type a "G" and then an "A", it first jumps to the first item that starts with a "G" and then the first item with an "A".  I want it to jump to the first item that starts with "GA."  What is the easiest way to accomplish this functionality?

Regarding multi column search, i want to clear you the situation where one column contains say FirstName and the another column contains LastName for the 'Contacts Combo box', then when user types either FirstName or LastName for the person, combo box should search for the appropriate value into both columns.

VS 2010 Populate Multi-column Listview From File?

Jun 14, 2011

I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have


It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.

GridView Display With Multi-Select ListBox

Oct 5, 2011

I have a list box that is bound to a table in a database. It produces a list of companies. The user will then come along and select multiple companies that they want to view information about, and then they hit a select button which I'll display the company information (e.g company name, company site, address e.t.c) in a gridview underneath. However the issue that I am having is that it only displays ONE of the multiple companies selected and its always the top one. How I get all the companies to be displayed in the gridview?

I am programming in vb.net

DataSourceID="SqlDataSource11" DataTextField="compName"
DataValueField="compDataID" SelectionMode="Multiple" AutoPostBack="True"></asp:ListBox>

VS 2008 Do Something On Each Item In Listbox And Multi Thread

Sep 18, 2011

this is going to be hard to explain but ill try. Question 1. Ok i have a list box with a few items, What i want for this example is to click a button and it will start on the first item and do: MsgBox ("this is item blah blah blah") then after that it will go to the next item and do the same and then the next and so on untill all have been done. The "blah blah" should be the item so if item was to say "hello" then the msgbox would say "this item is hello" I know this would be a lot of msgboxes to close, like if 50 items then thats 50 msgboxes to close, this is just for the example.

Question 2. Ok this is where ive tryed to learn but find it really hard (multithreading) Im wanting all to be multithreaded so all work at the same time, ive tryed a few times but the only way i see it is having a **** load of subs, like if i want it to use 10 threads then ill have to add the same code 10 times or somet, im not sure.

i have attempted all this and failed big time as my way was to get the first item and use that then remove it from the listbox BUT... with it being quite fast the 2nd 1 and 3rd 1 used the same item befor it was removed and to be honest i dont really want them removed. so my attempts took like 2-3 days that was a waste of time really. I Know this is a lot to ask but im in real need of it and these 2 things have driven me half mad.

DB/Reporting :: Use A Listview Or Similar As A Multi-column Combo Or List Box?

Sep 10, 2008

I have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.

I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.
