I have a form with a Listview. I have not manually added columns through the gui so I need to do this too.I have a stored procedure which returns two sets of data. One is titled url and the other occurrences in he procedure.I have bound the results to a dataset. I am having problems taking that dataset and putting the results in the listview. Here is the code I have:
It is not creating the column headers. It is not putting both results in the view. It is only putting the first column "url" It is not putting the next row on the next line, but placing it in the next column where the occurrences should be going. It is also not resizing the columns to match the data , but keeping at the size assigned (I assume) in the columns.add section.
I'm currently grabbing all files in a folder and displaying them into a listview. Below is the code I'm using:
If you look at the "For" line, you can see that pulling all files with an extension of .txt. There are some files that I need to pul with different extensions. I tried just doing "*.", and it would grab the files with not extension, but not the txt extension.
So, I wanted to know if there was some way to just pull all files or specify more than one extension.
I'm currently developing a download manager and converter for audio and video files. Does anyone know how can I get the music file from a specific folder from my computer (I already used openfiledialog) and putting it into a listview?
i made a media player program and i am having many problems! the main issue is that i have a listview that displays music playlist, how can i get it to navigate to the next item after the clicked one is over that way users don't have to click on the next one to continue their playlist?
I have seen many examples of populating a listview from a datatable or converting a datatable to a listview but what I am trying to do is exactly the other way around.
How can I convert/copy the contents of a winform listview to a datatable?
I have a listview with a context menu where users can multiselect items and choose one of the context menu options, I then loop the selected items and extract each selected row (listview item) and serialize it, instead of doing this I wanted to convert the listview to a datatable then add the datatable to a dataset and serialize the dataset.
I have a relatively simple Listview that suddenly needs (due to new requirements) to have it's 'layout' extracted to a DataTable so that a common routine can convert it to an Excel spreadsheet for export purposes.The ItemTemplate is just a series of Table Rows with some text, data-bound labels and textboxes with validators in the cells.Usually, when trying to pull out a particular value (like what was entered into a text box), I use the ListViewItem's .FindControl method.
For Each objItem As ListViewItem In lvwOptions.Items Dim objTextHrsLabor As TextBox = CType(objItem.FindControl("txtHrsOptByLabor"), TextBox) decHours = CDec(objTextHrsLabor.Text) Next
In this case, however, I'm trying to take all the data displayed - all the 'rows and columns' of the table that was created.Inside the ForEach / Next loop of ListViewItems, I started a ForEach/Next loop of Controls for each instance's controls but I got some really strange results returned (like controls that had a couple of table cells in them).
I get the sense I'm headed in the wrong direction. All I want is for the nicely-formatted 5-line, 6 column table to be converted to a 5-line, 6-column data table.
There's a thread that i'd read wherein you reply regarding on shortcut on populating a listview with databatable or dataset, but i forgot it. How did you populate a listview with datatable or dataset with just one line.
In datagridview .DataSource how about in listview ?

How can I get items in listview? I know how to get the current item if selected but I am trying to put it in a loop where I need to get my three row items there. I have 3 columns and I want to get there items and insert it in entry string.
This code is wrong Dim a As Integer = 0 For a = 0 To ListView1.Items.Count columname.Text = ListView1.FocusedItem.Text(a) columntype.Text = ListView1.Items(a).SubItems(1).Text columnscale.Text = ListView1.SelectedItems(a).SubItems(2).Text entry = entry + columname.Text + " " + columntype.Text + "(" + columnscale.Text + ")" + vbNewLine + "" & _ "" Next
But if I go into the properties of the ListView1 and look at the collection for the Items there is no place to set the Name.I can code Me.ListView1.Items(1).Name = "Name" and then I can code Me.ListView1.Items("Name")Where can you set the "Name" of the Items in a ListView?
I am trying to search through listview in VB.net 2008. It works fine with small list, but when the list is big ( around 25000 rows), if I search multiple items , it fails saying that index is not valid. Obviously what I understand is , it it tryiong to remove an index does not exist. But I am unable to figure out where exactly it is going wrong.
PS : while it is doing search through the entire listview, I am incrementing index = index+5 becasue I want the next 5 rows to be in the selection state as well.This is the code Private Sub TextBox1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyUp If (e.KeyCode = Keys.PageDown) Then
