So I have three listboxes, LB1 is an uploaded list, LB2 is a master list, and LB3 is generated from LB1 items that are NOT in LB2. I have a button that replaces the selected item from LB1 with the selected item from LB2, woot.Since LB3 is a subset of LB1, I want to be able to select the items from LB2 and LB3 and have it replace the item from LB1 but running into some trouble with finding the appropriate item without selecting it.

highlight Fred from LB1 and Freddy from LB2, click and Fred becomes Freddy in LB1. I want this same change to happen but by selecting the "Fred" located in LB3 (If LB1 is hundreds of names long, I don't want to have to sift through it and only make the changes that need to be made). [code]

I am trying to search through listview in VB.net 2008.

I was generously guided by the community to use LINQ to find duplicates on my listboxes the last time around. However, I am now in a tough spot because I need to find and remove duplicates from a multicolumn list view. I tried using LINQ but it says that the listview object is not "queryable". Is there a way for me to find and remove duplicates using only one column of the listview? [code]The code now runs fine when I call it. But it does not remove the duplicates:

View 2 RepliesI have a ListView of 4 columns, one of which is a monetary value.I am trying to add these values of 'selected' rows. I can add ALL row's values - but not selected rows. The code that I use actually highlights all the rows that contain the string that is looked for but the result is not correct. Let me explain: Say I am looking for all the rows that contain the word "Special" and that it is in 4 rows. The 4 rows are highlighted but the result is the value of the first row highlighted multiplied by the number highlighted. In a Console.WriteLine I find that the same numberRow is shown 4 times. I can't work out how to get each row's value.[code]

When the user selects a row in the listview, I need to pull out the EMPID item as a string variable.
View 6 RepliesI have this script which is designed to loop through all of the selected listview items, and delete them from the ftp server. - The list view item names are exactly the same name as they are on the FTP server.

View 3 RepliesI have a Form with listview of customer name. e.g. AAA, BBB, CCC, DDD, EEE. etc And 3 textboxes.
I want to be able to populate the textboxes when the user selects a customer. For example: If User selects AAA, textbox1.text = AAA, then if User selects CCC, textbox2.text = CCC etc.
I tired: (in a button on click event)
TextBox1.Text = Listview1.SelectedItems(0).Text
TextBox2.Text = Listview1.SelectedItems(1).Text
TextBox3.Text = Listview1.SelectedItems(2).Text
But this only works if the user selects 'all' 3 customers at once. I want to allow the User to populate each textboxes depending on how many they select eg. 'Upto' 3 customers .
I'm a student and I have a small project to create for my VB class. For the personal touch, I tried using a ListView to manage a SQL database (on a remote web server).What I need to do right now is determine how many items are selected (if more than one, enable delete and edit buttons, if more than one, disable edit button). I searched a lot for that, but didn't find anything working with me.Do you know a simple way I could get the number of items that are selected in my ListView?

The array will have two dimensions, one for column 1 and the other dimension for column 2. I am a little lost on how to iterate over the listview items. I figure it would be a for each statement. Its also the actual call that passes the found item and sub item to the array I am struggling with.
