During the MouseHover event the Item in ListView is easy to get using GetItemsAt(X,Y). How does one obtain the text in a SubItem cell? There is no GetSubItemAt method.

Thanks for any ideas,
 
Hi Tom,

Assuming you use MouseMove to get the X and Y, you can calculate which sub item is under the cursor by comparing X with the column widths.

Note, this will only work if FullRowSelect = true; or MouseMove won't trigger the event.

Some sample code from the MouseMove event, but you can easily store the position for later use by MouseHover

ListViewItem l = listView1.GetItemAt(e.X, e.Y);
if(e.X <= listView1.Columns[0].Width)
label1.Text = l.SubItems[0].Text;
else if(e.X <= (listView1.Columns[1].Width + listView1.Columns[0].Width))
label1.Text = l.SubItems[1].Text;
else if(e.X <= (listView1.Columns[2].Width + listView1.Columns[1].Width + listView1.Columns[0].Width))
label1.Text = l.SubItems[2].Text;


Happy coding!
