I have been playing with, and researching, this all day and can't figure it out. I have a Windows Explorer style form with a TreeView and a ListView. I've populated the TreeView with directories and when a node is selected, the ListView fills with the contents of the directory associated with that node. No problem there, but I want to be able to select a directory in the ListView and automatically select the associated node in the TreeView, just like it works in Windows Explorer. All the information I've found online tells me how to populate the ListView from the TreeView, but I haven't found any good examples of how to populate the TreeView from the ListView.

I'm having some weird trouble with adding a new value in a combobox.The combobox has a datasource which is a bindingsource.The combobox's list is filled from a different table through a different bindingsource. Combobox.valuemember = "ID" and Combobox.displaymember = "Description".When a user types a value in the list, I want to add the new value to the table which is the source for the list. (Which is not the problem, but I don't get that far) The problem is that when the user types a new value in the box, it totally disappears as soon as the user tabs out of the combobox. So, in the event combobox.Validating the combobox.text property (nor any other property) does not show the new typed value.

View 2 Repliesassign 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?

Say I have Combobox1 with items (1)Breakfast (2) Lunch (3)Dinner
and I have combobox2 with items (1)Apples (2)Bananas (3)Grapes(4)Oranges
Now when I choose Breakfast in combobox1, I want user to see all 4 items in combobox2. But when I choose Lunch in combobox1, I only want user to see (1)Bananas(2)Grapes(4)Oranges in combobox2, hiding Apples.
Does anyone know a code where I can hide an item in a combo box depending on the condition?

I am using visual basic in VS 2008 and trying to learn how to assign a value to a word in a combo box using case select, this is my first attempt at programing and i just can't work out what to do next. So far i have two combo boxes a label and a button, i want the word, first to = 11, second = 9, third =7, fourth = 5. All it is doing at the moment is adding the list index value and displaying that total in the label. I want it to display for eg: if (first=11) and (second=9) are selected a total of 20 in the label,and so on for what ever combination is selected.

When my application starts, it scans the computers registry for COM ports and adds them in the combo box. The combo box first index is just a blank, and the second is COM1, COM2,...COMn. What I want to do is by default, I want my program to select the first COM port in the combo box, so in this case, COM1.
I know I have to use the PORTNAME property of the serial object, but not sure how I would set that equal to the 2nd index of the combo box.
The ComboBox Items collection is an ObjectCollection, so of course you can store anything you want in there, but that means you don't get a Text property like you would with, say, a ListViewItem. The ComboBox displays the items by calling ToString() on each item, or using reflection if the DisplayMember property is set.
My ComboBox is in DropDownList mode. I have a situation where I want to refresh the item text of a single item in the list when it gets selected by the user. The problem is that the ComboBox doesn't re-query for the text at any time besides when it loads up, and I can't figure out how else to do what I want besides removing and re-adding the selected item like so:
PlantComboBoxItem selectedItem = cboPlants.SelectedItem as PlantComboBoxItem;
// ...
cboPlants.BeginUpdate();
int selectedIndex = cboPlants.SelectedIndex;
[Code]....
This code works fine, except for the fact that my SelectedIndex event ends up getting fired twice (once on the original user event, and then again when I re-set the property in this code). In this case, it's not a big deal that the event is fired twice, but it's inefficient, and I hate that. I could rig up a flag so it exits the event the second time, but that's hacking.
How can I convert the item number in the combo box to be use able? I keep getting told to change RaceNum to a double but I need the RaceNum to stay as a int so it reads the files 1-15 but it starts at 0.
