Multi Select On A Listview Control?

Apr 19, 2012

Can a listview multiselect in the same way as a listbox can, when it is set to electionMode = multiSimple?for instance when the listbox is set to selectionMode = multiSimpleyou can just select any number of items in the listbut...with a listview you can only multi-select when you hold down Ctrl. As soon as you lift the Ctrl key and click on an item it de-selects everything and only selects the last one you selected

GridView Display With Multi-Select ListBox

Oct 5, 2011

I have a list box that is bound to a table in a database. It produces a list of companies. The user will then come along and select multiple companies that they want to view information about, and then they hit a select button which I'll display the company information (e.g company name, company site, address e.t.c) in a gridview underneath. However the issue that I am having is that it only displays ONE of the multiple companies selected and its always the top one. How I get all the companies to be displayed in the gridview?

I am programming in
<asp:ListBox ID="ListBox1" runat="server"
DataSourceID="SqlDataSource11" DataTextField="compName"
DataValueField="compDataID" SelectionMode="Multiple" AutoPostBack="True"></asp:ListBox>
<asp:SqlDataSource ID="SqlDataSource11" runat="server"
ConnectionString="<%$ ConnectionStrings:IWSRiskAssessmentConnectionString %>"

Populate Listbox From Multi-select OpenFileDialog?

Feb 23, 2010

I've spent FAR too long trying to troubleshoot this simple operation.I want the user to select multiple files in an OpenFileDialog (called OpenFileDialog1), click OK, and then have the filenames display in a listbox (called ListBox1). When I run, the openFile dialog allows the user to select mutliple files. However, on clicking OK, the dialog repons allowing the user to select only a SINGLE file. Then, it throws an "outside of array" exception.

VB 2010 List Box Multi Select Loop

Jan 24, 2012

i have having a annoying problem to do with loops.


When the user selects a few rows from my list box i want to run code on them selected items which i can do fine, but when the user only selects one of items and hits the button. it goes throught the loop first and gets the picture and all is fine its when it comes back to this function after there are no more items to perform tasks on. it increments index again and then falls over because its out of bounds of the array. i want it to stop after one loop but i also want it to be able to have the multiselect option still so the user has a choice.

ListView - Resize Multi Columns In Form

Aug 19, 2011

I got a very simple question regarding resizing listview columns. I have a form with a listview anchored to it (top, bottom, left, right). The form is resizable and the user will be able to resize the listview columns manually. However, I need the listview to resize its columns automatically when the form is resized (especially when its maximized).

But, I don't want all the columns to resize, only the ones I choose. For example, the listview will have 6 columns in total (0-5). When the user resizes or maximizes the window, I need only columns 2 and 4 (or columns 3 and 5 or columns 1 and 5) to resize. Now, I have come up with two pieces of code as listed below.

Code Part A: The following code only resizes one column. When the form is maximized, only the column ID provided will resize and fill the rest of the control. It works perfectly but I need to be able to resize multiple columns (as explained above):

Public Sub lvResizeSingleCol(ByVal resizeColumn As Integer, ByVal listViewName As ListView)
Dim w As Integer = 0
For column As Integer = 0 To listViewName.Columns.Count - 1
If column <> resizeColumn Then
w += listViewName.Columns(column).Width
[Code] .....

VS 2010 Populate Multi-column Listview From File?

Jun 14, 2011

I am trying to populate a multi-column listview from a file. I have gotten as far as reading the correct data from the file to an array and populating the correct columns with said data. However, sometimes the array will span multiple lines of data in the file and I need all of these matches to populate the listview but the code that I have now only populates the listview with the data from the first matching line. I have tried declaring the variables as listviewitems instead of strings, which allowed me to use listView.Items.AddRange(arr) but then all of the data appeared in the first column instead of spread across all columns like it is supposed to. At this point I am at a loss because I can only figure out how to either fill the first column with all data or fill all columns with only the first line of data. Here is the code that I have


It is really only the last part of the If.. Then statement that I need help with. I was thinking that a loop would accomplish what I am trying but I am still pretty new to VB and do not know the correct code.

DB/Reporting :: Use A Listview Or Similar As A Multi-column Combo Or List Box?

Sep 10, 2008

I have been reading books and the forums for a rew days now trying to work out how to use any control to carry out the following:Basically, I want to display a selection e.g "Club Name" in a combobox (or similar control) and have the ID of that selection in a separate hidden column e.g. "ClubID". This will allow me to easily reference and store the actual "ClubID" in the required record when I save it back to the database.I can not use the "SelectedIndex" property of the control as the combobox is populated from a 'sorted' stored procedure so the "SelectedIndex" does not match the actual index of the selection.

I have found lots of posts saying use the "ListView" control, but none of them actually show examples of how to bind the control to a data control to acheive what I need.What I am after is a turorial showing ADO code (because I want to hard code this to get a better understanding of how it all works) binding a multi-column control to a SQL database.

ListView Rowheight Varies - Using ListView Control, With SmallIcons Style ?

Mar 15, 2012

I'm using ListView control, with SmallIcons style in VB.NET. Icons are loaded fine, but when I start to scroll ListView down or up from scrollbar (clicking from arrows), rowheight drops to about half from normal in next 20-30 rows below/above upper/bottom row (depends from the scrolling position). After 1-2 seconds, ListView is "refreshed" and scrolling continues normally. When focus in on the ListView and I'm moving up/down with arrow keys or PageUp/PageDown, everything is normal. Any suggestions, what is happening? SmallIcons size is 16 * 16. Is it compulsory to set "Blank icon" with SmallIcon size to all rows, when adding them or what? Wasn't like that in VB6, how is it in VB.NET?

VS 2008 - How To Access Listview Data - Program That Contains A (listview) Control

Sep 22, 2009

I have a vb-2008 program that contains a (listview) control.

View = details
AllowColumnReorder = true

Lets say the table has 3 columns (a,b,c) and 1 row of data.

a b c
1 2 3

I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.

c a b
3 1 2

Statements like:

.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString

Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.

How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?
