listView doesnt show content

Question

Hello

Im working with ListView in C#.NET.

Im using code similar to this:

string[] row1 = { "s1", "s2", "s3" };
listView1.Items.Add("Column1Text").SubItems.AddRange(row1);

However I can't see the content, only the name of the column. Why is this?

Answer 1

It looks like you're adding subitems. I don't know what columns you're showing, but the first column will be the item text itself, with further columns being the subitems.

So, if I want to show A B C, I need to add an item of A with two subitems of B and C. That will show all three. If you want to see all three in your example, do an Items.Add on each one. They'll all fill the first column.

Answer 2

Try something like this:

 ListViewItem item = new ListViewItem("Column1Text"); 
 item.SubItems.AddRange(row1); 
 listView1.Items.Add(item);
 listView1.View = View.Details;

Answer 3

well I think I found the problem...I didnt create columnHeaders...before.if I want to add another array (row2) for another row..? I tried:

ListViewItem item = new ListViewItem("Co1"); item.SubItems.AddRange(row1); listView1.Items.Add(item);
 ListViewItem item1 = new ListViewItem("Co2"); 
item.SubItems.AddRange(row2); listView1.Items.Add(item1); 
listView1.View = View.Details; 

but Im not getting the data in the in Item1 but in Item..? any idea what Im doing wrong? Ty!! ^_^)

More comment to the answer: Never-mind! I fixed it!! Ty kyle to gave the idea to check the column Headers...

Now I got a new questions

....I added some columnheaders to the listview inthis case where it's very simple BUT if I'm getting arrays with different sizes...Is it any way how I can make this columnHeaders changing, adding more column Headers in case the size increase or decrease? (writing some code maybe)

Gracias!
