Listview ... "A friend inseparable"
In each development is almost inevitable that I do have to use a listview. So I consider it very useful control. At first it cost a bit to understand its operation and it took several months to realize their full potential ... but since we understand we are inseparable.
Definition
To define a simple tell a listview is a collection of ListViewItem's
In order to populate a listview must first create a ListViewItem object (or more) and then appends the object to listview using the add method of the items property.
'Is supposed to have a form called Form1 WinForm 'With a listview control called ListView1 Dim item As ListViewItem item = New ListViewItem ("Customer 1") ListView1.Items.Add (item) 'So we can fill using a for loop / next For i As Integer = 1 To 10 Dim item As ListViewItem item = New ListViewItem ("Customer" & i) ListView1.Items.Add (item) Next
A ListViewItem can store various data such as NAME, LAST,
ADDRESS, etc..
This requires adding (add) to each ListViewItem the necessary subitems.
Dim item As ListViewItem item = New ListViewItem ("Name 1") 'Now this I add an item object 'Sub-item for each additional data item.SubItems.Add ("Name 1") item.SubItems.Add ("Address 1") item.SubItems.Add ("Phone 1") 'It only remains to add the item to order 'ListViewItem's collection of objects of 'ListView1 the same way we did before ListView1.Items.Add (item)
A listview has different views to display data, these are Details,
LergeIcon, List, SmallIcon and Tile.
Following is a description of each one taken from the help of visual studio:
| Details | Each item appears on a separate line with more detailed information of each element organized into columns. The column on the far left contains a small icon and a label, and subsequent columns contain subitems specified by the application. The columns include a header that can display a title for the column. The user can change the size of each column at runtime. |
| LargeIcon | Each item appears as an icon size below which contains a label. |
| List | Each item appears as a small icon to the right of which contains a label. The elements are arranged in columns without header. |
| SmallIcon | Each item appears as a small icon to the right of which contains a label. |
| Tile | Each item appears as an icon labeled size of element e subelement information located on your right. The application specifies the information subelement of that appears. This view is only available in Windows XP and the family of Windows Server 2003. In earlier operating systems, this value is ignored and the ListView control is shown in the view LargeIcon . |
To view the data when we use the view "Details" we must first create
listview columns agree to the amount of items and subitems we have.
Dim column1 As New System.Windows.Forms.ColumnHeader Dim column2 As New System.Windows.Forms.ColumnHeader Dim column3 As New System.Windows.Forms.ColumnHeader Dim As New System.Windows.Forms.ColumnHeader column4 column1.Text = "Name" column2.Text = "Last Name" column3.Text = "Address" column4.Text = "Phone" column1.Width = 40 column2.Width = 30 column3.Width = 30 column4.Width = 20 'It is always important to make sure there are no 'Columns and it is best to delete them before 'Add the new columns ListView1.Columns.Clear () 'Now add the new columns ListView1.Columns.Add (column1) ListView1.Columns.Add (column2) ListView1.Columns.Add (column3) ListView1.Columns.Add (column4) ListView1.View = View.Details
The column settings can also be done in design mode from the
columns property, it s not open a wizard from which you administer
listview columns.
Properties
There are some very useful properties that can not fail to know then
mention that I use most. The remaining properties are left to
capaciddad exercise your research.
| FullRowSelect | SETTING This property always a True and its function is to highlight the whole line when Working in Details view. |
| MultiSelect | Enables (true) or disable (false) the selection of multiple elements within listview. |
| HideSelection | If the property is True you will not see that item is selected when the control loses focus. In some cases it is important to disable (false) this option to keep track of the active item. |

a question about your post,
how to add 2 items to my listview with the property equal to largeicons view and I would love for each items had a different image?
Regards,
agredezco your cooperation in advance. My question is the following: if I have already agredados several items to a listview. none of these is selected (so I have not been clicking on it).
how do I know that the code listview has no item selected?
listview.listitems something like (i). select in vb 6.0
many thanks
as we have a friend in common
just in vb.net 2008 can not find all the options (properties) that were useful to set me ... will have the same capacity as that of vb 6??
Hi
I commented that the new ListView Control visual basic. Net exposes most of the properties and methods which had in Visual Basic 6 and only need to consider some names have changed.
The ListView control exposes only some new properties. This group includes Activation (specify if the elements are activated with one or two clicks), HeaderStyle (if you can click on the titles of the columns) Scrollable (to be defined as False to prevent movement), LargeImageList (ImageList control used images for large icons mode) and smallImageList (ImageList control used in all other modes). Note that the property view defines the display mode, as in Visual Basic 6, but the Report has been renamed so as far as Details.
I hope I have cleared some of your doubts.
Regards
Hello I hope you can answer ...
I scheduled a listview to carge me a list of customers directly from the database, my problem is I want you to select the customer with the option FullRowSelect listview and return to get the data from the selected row, so back to create an object "customer" data from the listview, so idk if will understand as I explain, thank you very much for everything, thanks for your time.
Hi Elisha, I first want to congratulate you on the blog .. is very good and served me well.
Now I make a query:
Considering the first example
item = New ListViewItem ("Name 1")
'Now this I add an item object
'Sub-item for each additional data
item.SubItems.Add ("Name 1")
item.SubItems.Add ("Address 1")
item.SubItems.Add ("Phone 1")
'It only remains to add the item to order
'ListViewItem's collection of objects of
'ListView1 the same way we did before
ListView1.Items.Add (item)
As I can do to pass the subitems at different textbox??
Greetings and thanks
And solve it, right out of the guide to change the listview.
Regards
to refer to the different subitems just use an index as I show below:
TextBox1.Text = item.subitems (0). text
textBox2.Text = item.subitems (1). text
textBox3.Text = item.subitems (2). text
Luck
I need help with a question that I have long ago and no one could solve it. Position a full database in a listview, the issue is that as I'm adding these data are loaded at the end and there comes a time not look like I can do to keep the scroll bar at the end to see the last thing I adding.
From already thank you very much
Martin, I wrote a post explaining how to solve this problem. I hope you serve.

Hi
Very good your blog also has a lot of aesthetics ... that is rare in developers ;)
Now, my question is this:
Any example that fill a listview from a hashtable that contains multiple instances of a specific class? I know I use a Foreach, but when running, the listview is "blank". I do not know if I express it.
Thank you very much for your reply.
Hi
About my problem I clarified that I discovered how to make it work, just that I do outside the tabcontrol which was the listview, because I was in a tabcontrol and what will not work?
Thank you very much for any response.
