Getting Data From WinForms ListView Control?
Mar 24, 2010
I need to retrieve my data from a ListView control set up in Details mode with 5 columns.
I tried using this code: MessageBox.Show(ManageList.SelectedItems(0).Text)
And it works, but only for the first selected item (item 0). If I try this:
MessageBox.Show(ManageList.SelectedItems(2).Text)
I get this error: InvalidArgument=Value of '2' is not valid for 'index'. Parameter name: index
I have no clue how I can fix this, any help?
Edit: Sorry, should have said, I'm using Windows.Forms :)

If I enter a data in a textbox, I want my listview to select the same data entered in the textbox. Example: I have a StudentNumber column in my listview and it has data on it (ex. 123456)
I will enter 123456 in the textbox. The ListView must select 123456?

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?

I have a form with a listview object and a button.I have a function that returns a Datalist.When the exception from the thread is throw in is supposed to run the Apps_Add Procedure, which it does.But on one line lstApps.Items.Add(l_apps) I am getting the following error."Cross-thread operation not valid: Control 'lstApps' accessed from a thread other than the thread it was created on."The data is being returned from the threaded procedure but I can't understand how to add the data to the ListView control without getting this error. This code works perfectly fine if I don't use threading.[code]

I have a ListView setup in details mode that looks like this: When the user presses the delete button, I need to go ahead and delete their record from the database. This I can do fine, but I'm stuck on how I retrieve the data that is highlighted in the ListView control. I've tried using Google but all the examples I found have failed to work.

I am trying to make a listview custom control based on the standard listview control that will allow me to drag a column header outside the standard listview control and drop it on a panel. I plan to use the drop event to determine which column I should group by view on.

I need to grab some data from a webpage but for me the main problem is I can't grab the data the way I want.

I am giving the format (source) of the webpage below and my coding in vb.net (2008),
<br>
<span class="inputFieldLabel">Following Are ...</span>
<span class="inputFieldLabel">01/02/2011</span>

what I am trying to do is, when a ListView loads, for the code to check the entry in column one, and then return a message box if the column contains a specific date.
I am using:
SUB I DONT KNOW THE METHOD TO INSERT THIS INTO. I NEED IT CHECKED WHEN THE LISTVIEW CHANGES
If lvuPreviousJobs.SelectedItems(0).SubItems(2).Text = "31/12/9999" Then

I am using Visual Studio 2008 and VB.NET. I've got a listview control on my form and I've added columns using the windows forms designer. As you know, if you double-click on the sizer or divider or whatever you want to call it between two columns, the column on the left will autosize (unless you disable that). How can I catch this specific event? The ColumnWidthChanged event and the DoubleClick event are likely candidates, but in the ColumnWidthChanged event, there's no way I can see to determine if it was an autosize. Similarly, there's no simple way to catch what was clicked exactly with the DoubleClick event. how I can catch this specific event type?

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?

know the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse?I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects.I've had a look in reflector but it's one of those controls where most of the implementation is not viewable.
ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this?

this is my absolute first attempt at the mschart control in a winform, so any help would be appreciated - i have sales reps that issue quotes to customers and would like to plot number of quotes by month using the mschart control.I have a dataset populated with a single table with 2 columns in it - sales_rep and quote_issued_date (there's more, but i'd like to only focus on those two because they contain all the info i need)i have a windows form with an MSChart control dropped on to it. I'm trying to get this to work on a 'column' chart type.i'd like to count the number of records in the dataset per sales rep per monthi'd like to get the x axis to be months in the year (fixed, not drawn from the data) - jan thru dec.
i'd like to get the Y axis to reflect the highest count of rows per rep per month + say....10% (so the graph doesn't peak out at the top every time, it would be more for aethestics)i'd like to get the columns displayed in the graph to be each rep, each month (ie for january john has 10 quotes issued, bill has 5, tom has 31 - for feb john has 3, bill has 10, tom has 19 - etc etc etc) - because the form is just a quick visual, i'm dumping any code in the form load event and calling it good.
