I found that the following code didn't work for me

ListView1.ListItems.Remove(ListView1.SelectedItem) '// removes the selected item

I had to use

ListView1.ListItems.Remove(ListView1.SelectedItem.Index) 

Also  - it wasn't obvious to me to start with  ( I'm a newbie to listviews )

but to  'get at' the data in the views one had to use

ListView1.ListItems.Item(x)    where  x is a valid number in the  range 1 to ListView1.ListItems.Count  (NOT   0 to .Count - 1 as in normal Visual Basic)

Hi..

I using ListView in C#.

I tried to add text into certain colum in ListView.

For example: I have 3 columns, Column1, Column2, Column3.

I want to insert "TEST1"  and "TEST2" in Column2

How can I going to do in C#?

Thank you

Halina

Hey everyone here are some example of Database that use ListView:

if u need in C# pls copy this code convert to C# your self.

1. Use Microsoft Access Database

• Module1 code

2. Use SqlServer

connect direct to SqlSever (MS SQL Server Studio 2005)

Imports System.Data.SqlClient
Dim Cnn As New SqlConnection
Dim CnnStr$
CnnStr = "Data Source=PC2\SQLEXPRESS;Initial Catalog=KhmerDictionary;Integrated Security=True;Pooling=False;"
Cnn = New SqlConnection(CnnStr)
Cnn.Open()

Connect Indirect to Sql Server Database File

Imports System.Data.SqlClient
Dim Cnn As New SqlConnection
Dim CnnStr$
CnnStr="Data Source=.\SQLEXPRESS;AttachDbFilename="C:\NimolProject\Dictionary Testing\Original DBDictionary\KhmerDictionary.mdf";Integrated Security=True;Connect Timeout=30;User Instance=True"
Cnn = New SqlConnection(CnnStr)
Cnn.Open()

• Form1 Code need 4 textbox,one Listview,2 Error provider,8 command Button, 1 Label name lblrecord
• Captiontext :New , Update, delete, Save, |<, <<, >>, >|

Public Class Form1

Private WithEvents button1 As New Button

Private mouseX, mouseY As Integer

End Sub

End Sub

End Class

i hope you cam customize this code with your own project  thanks

if this is not enough pls give some idea ...na

ListView1.SelectedItems(0).Remove()

Or to remove all selected items:

For Each I as ListViewItem In ListView1.SelectedItems

    I.Remove()

How to sort a ListView control? Here is the code I have written to handle just that. This code also includes a context menu of items I found I needed on almost every ListView I used (I use them alot).

Can either create a file with this in it and add it to any project you need it in, or you can create a Class Library and add this code, compile it and add a reference to any project you wish to use this code in.

How to use the ListViewSorter:

In your ListView's ColumnClick event, place this line of code:

    ... 

    SortListViewColumn(sender, e)

     ...

How to use the context menu:

In your form's Load event, add the following code.

    ...

    Dim objListViewMenu As New clsListViewMenu(True)

    ListView1.ContextMenuStrip = objListViewMenu.ListViewMenu

     ...
 

Or, if you have a Context Menu you need for the list view, you can merge them with this line of code:

    ... 

    ListView1.ContextMenuStrip = objListViewMenu.Merge(YOURCONTEXTMENU)

     ...

There are various properties associated with the ListViewMenu object, all should be pretty self-evident.

Enjoy...
