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
[Code]....
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?

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
[code]....
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
ReadArrayString(0)
ReadArrayString(1)
ReadArrayString(2)
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
TypeComboBox.Items.Add(ReadArrayString(2))
End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal
Bird
Fish
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
[code]....
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.

i have having a annoying problem to do with loops.
[Code]...
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.

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]...

I have a program and I get time data from a sqldb and display it in a column in a listbox. What are the proper steps for adding the time as I iterate through the data in the column? I figure I will need to do some conversions on the time to be able to add it and display it as a total.

I need to add data into a multi-column list, manually, in codes. I am using VB Express 2008. Could someone please hint me on how to do this with the following controls:
The ListBox or the ListView
The Grid (I think it is the DataGridView)
Or anyother simple way of doing the stuff. All I want is simplicity.

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.

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.
for my fifth question consider the same combo box with FirstName, LastName all typed together shows in one column only then, by default combo box searches only for strings that 'Start' with the string typed in the textbox portion, insted of which i need a feature which allows me to let set the behavior of combo box search system tobe able to search for the typed strings within any part of record.i.e. If user types 'Ja' in textbox portion, the the list should show following maches

Populate *multi-column* ListView with *simple* XML data?

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.

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

I've spent FAR too long trying to troubleshoot this simple operation.I want the user to select multiple files in an OpenFileDialog (called OpenFileDialog1), click OK, and then have the filenames display in a listbox (called ListBox1). When I run, the openFile dialog allows the user to select mutliple files. However, on clicking OK, the dialog repons allowing the user to select only a SINGLE file. Then, it throws an "outside of array" exception.
