Assign An Item To A Group In List View?
Mar 23, 2009
I am trying to develop a recipe manager that allows a user to create a shopping list. I've already determined that I want to use a list view for this job. I want to be able to group the items in the shopping list by the appropriate grocery aisle (i.e. Dairy, Bread, Canned Goods, etc.) I'm not sure how to assign the items to the appropriate group as the user selects each item.
I haven't started actually building the application yet as i'm still in the development stage, but i have been testing the list view out to figure out how it works. i've figured out how to add items. i just don't know how to specify the group that each item should belong to.

I wish to create a drop-down list box with items in it. Easy to do and done that. What I also wish to to is assign a numerical value to each list item. I believe under VB6 is was done using the list's `Value` property to set and get the item. It's so I can write a one byte value to a file but display a text value on the form. Don't wish to mess wish classes and arrays, but if I have to I guess it'll be have to be done.Was looking at some examples of making in-memory arrays/datasets for a list-box but just sees like a programming overkill for the simple thing I wish to do.Put it another way....
List box item 1 = "First option". List box value 1 = 35
List box item 1 = "Second option". List box value 1 = 44
List box item 1 = "Third option". List box value 1 = 3
If the user selects "Second item" from the drop down list box then that property do I use to retrieve that list item's value `44`. Also, when I pprogramatically populate the drop-down list, how to I set each lite item's `Value` property accordingly. As in the example 35, 44 and 3 Tried using `SelectedItem` and `SelectedValue`?

I am creating a program that allows a user to view a list of foods in a combo box, add that food unto a list box, and adds all of the calories of that food together. When the user highlights their select food, the program automatically shows the amount of calories for that particular food in a text box. The program is getting the food and calorie information from an access database. I managed to get all of the food calories to add up properly, however, I ran into a problem. Sometimes, well, most of the time, when I select certain foods from the combo box, the program automatically reselects another random food, usually a food that begins with either an A, B, or C. Also, the other random food that the program chooses usually has the same amount of calories as the food I originally wanted to choose. I have over 6,000 items in the database. I don't understand why this is happening. This is what my code looks like for the button that adds each food to the list box:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
Foods_Selected.Items.Add(ComboBox1.Text)
Static i As Single
[CODE]...
And this is what my code looks like for the button that adds all of the foods together:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim x As Single
Dim TotalCalories As Single
[CODE]...
I have no idea what to try. It's like the program just skips over random foods, even though all of the information for them is in the database.

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag
[CODE]...

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.

I have the following query that groups parking spaces by their garage, but I can't figure out how to iterate the data in the view.
Public Function FindAllSpaces() Implements ISpaceRepository.FindAllSpaces
Dim query = _
From s In db.spaces _
Order By s.name Ascending _
[code]....
The controller is taking the query object as is and putting it into the viewdata.model and as stated the view is not currently strongly typed as I haven't been able to figure out how to do this. I have run the query successfully in linqpad.

assign a particular value to each item in a combo box? Or, alternatively, some similar control? Specifically, I want a drop down list to select from a list of countries. I then want to get the ISO 2 letter abbreviation for the selected country. I could have a section of code like this
selected_country = cmb_country.SelectedItem.ToString()
if selected_country = "Afghanistan" Then
country_code = "AF"
ELSE IF selected_country = "Aland Islands" Then
[code]....
but this will get rather tedious.Is there an easier way to do it? I would like to be able to assign a value to each line in the list, like
Afghanistan, AF
Aland Islands, AX
Albania, AL
then get the value for the selected item. Is this possible? If not with a combo box, then any other control?

rather than having all the if statements can you have one line that says Label1.text = "You selected " & RadioGroup1.Text
Sub SubmitBtn_Click(Sender As Object, e As EventArgs)
If Radio1.Checked Then
Label1.Text = "You selected " & Radio1.Text
ElseIf Radio2.Checked Then

I have a property called ReplacementTo and I set a value to it based on the selecteditem from the combobox, like this:
classEquipmentItem.ReplacementTo = cmbReplcmnt.SelectedItem.ToString
Now I can't use cmbReplcmnt.Text because what I actually need is the value of that SelectedItem
So problem is, if the user leaves the combobox as blank, it throws a null exception.I decided to use the IIf function then:classEquipmentItem.ReplacementTo = IIf(IsNothing(cmbReplcmnt.SelectedItem.ToString), classEquipmentItem.ReplacementTo = "", cmbReplcmnt.SelectedItem.ToString)
Unfortunately I still get the error I tried using a Try-Catch for it and it worked, but I don't want to rely on the Try-Catch, so I was wondering is there a another way to work this through?
