Do I really have to go through all this just to find out what item has been selected in a ListView?

Isn't there something fundamental like this? Is absolutely everything in VB.NET buried beneath a colossal heap of bureaucracy?
I'm adding a ToolTip to a ListViewItem. However, the ToolTip only shows up when the user hovers over the first cell in the row to which the ToolTip has been applied.[code]Any idea how I can make the ToolTip show up on a specific cell in a row, or even the entire row?
View 1 RepliesI'm using the below code to produce a ToolTip for each row of a ListView.
When moving vertically across the ListView a ToolTip will appear when the mouse touches between two rows - bypassing any of the ToolTip's options.
Private m_HoveredItem As ListViewItem
Private Sub ListView1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lv.MouseMove
[Code].....
I'm not using the ShowItemToolTips property of the ListView because I want to have a more formatted ToolTip (ToolTipIcon, Title etc) I don't believe these options can be set for the ListViews ToolTip?

I am filling a listview control with a big number of items but i came across an problem, the repeated values. In those items i use .Text and .Tag so i can relate some hidden values per item. I have been trying to use the items.find() with no luck since it looks like to search for keys, which i don't really have. Every item has different .Tag values but it can happens that they have the same .Text Is there any way to remove or just not add items based on a .Text search in the ListView?

View 5 RepliesI have a listview where I can show a tooltip over each item and displays fine.However, I can't replicate for a Button.

I have tried all different variations, but nothing really seems to work. The tooltip flickers on the button, but is constant on the listview.
I was trying to at random select a listview item, I tried:

View 12 RepliesI have a listview, and when you right click, it shows some things. I need to make it see if an item on the listview is selected. Is there a way to do this?
Like, this doesn't work, but in code it would be like
If listview1.HasItemSelected = true then'code here end if
I want to retrieve the selected item in my listview as a string. I have 2 columns, Name and Version. When i click a button it should come up the value of the column Name of the item that is selected.
Something like this:
MsgBox(Listview1.SelectedItems.Text)
I remember doing this in a checkboxlist element, but with listview element its giving a hard time.
Private Sub CheckedListBox1_ItemCheck(ByVal sender As Object, _
ByVal e As ItemCheckEventArgs) Handles ListView1.ItemCheck
If e.NewValue = CheckState.Checked Then
For index = 0 To Me.ListView1.Items.Count - 1
[Code]...
ok I made my self a listview with a checkbox on it. I was wondering if it was even possible to add something to my form so when I build my project and I rightclick on my list view item a menu will open saying:
delete item
Clear Item
A menu (not a form) just like when you do a right click on your mouse.
I need to add multiple images to a list view item dynamically. For example, if an alarm exceeds limit one image has to be displayed and is fine with me.But when the user clicks alarm inhibit checkbox,then two images has to be displayed,one for alarm existance and second for manual operation which represents the user action.Both the images have to be displayed under one column only..

Ok, so I have a listview on one form, and when a button is pressed it opens up a new form with the contents of the selected listview item and it's subitems in a series of textboxes. The user can then change the data in the textboxes and either press save to make the changes or cancel to close the window. What command would I use to change the selected listview item and subitems to whatever is in the boxes?
this is the code that populates the boxes:
Private Sub Form_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim appeditcontents As String = main.passlist.SelectedItems(0).ToString
[Code]....

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
