Hi, I am new to using C# but sadly quite stuck.

I'm trying to populate a column in my list view with the name of any selected files which the user has picked from within a dialog box.

Currently I can get the name of the file to be input to a label but not in to any of the columns in the list view.

I have used the following code to add to the label:



CODE

OpenFileDialog opensinglefile_dr = new OpenFileDialog();
opensinglefile_dr.ShowDialog();

label1.Text = opensinglefile_dr.FileName;


I have tried replacing the lastline from above, which puts the name in to the label with:

CODE

fileinfoViewer.filename.Text = opensinglefile_dr.FileName;


I thought it would be [listview name].[column header name].Text = dialog box but this doesn't work.

Any suggestions at all?

Thanks

When looking to change the text in an item in a ListView in a specific column you need to be looking into the SubItem property. Here's an example. I put a ListView on a form, set it's view to View.Details (that shows column headers, etc), I then created two ListViewItems and added SubItems to them. At the end I changed the text of the second column in the first row by using ListView1.Items(0).SubItems(1).Text = "Hello". Here's the example:

csharp

private void Form2_Load(object sender, System.EventArgs e)
{
	ListView1.View = View.Details;
	ListViewItem item1 = new ListViewItem("item1");
	item1.SubItems.Add("Item 1");
	item1.SubItems.Add("Item 2");


	ListViewItem item2 = new ListViewItem("item2");
	item2.SubItems.Add("Item 1");
	item2.SubItems.Add("Item 2");

	ListView1.Columns.Add("Column 1");
	ListView1.Columns.Add("Column 2");

	ListView1.Items.AddRange(new ListViewItem[] {item1, item2});
	ListView1.Items[0].SubItems[1].Text = "Hello";
}

Thanks for the reply there. I was able to understand part of what you meant and used the following line to get the dialog box to add text to the first column in the list view.


CODE


fileinfoViewer.Items.Add(openSingleFile.FileName);




The problem I have now encountered is that this does not just add the name of the file but the path to the file as well so it adds:

C:\New Folder\TestImport.doc

When all I want to add is:

TestImport.doc

I've tried using all sorts of things as well like:

CODE


string fileNameOnly = System.IO.Path.GetFileName(openSingleFile);
fileinfoViewer.Items.Add(fileNameOnly);



I can't get anything at all to work though, I just keep getting error/debug messages no matter what I try. This is only the start of my problems as well!

Anything at all to point me in the right direction would be a great help!

Simple. Rather than using FullName, just use Name

Example:
openSingleFile.Name
