Change ListView SubItem value

[Kayess Tech]

Hi All, I am using a ListView Control to display clients connected to a server. The ListView is set to View.Details and has three columns, 1) Client ID, 2) Client Name 3) Connection Status. What I would like to do is update the 'Connection Status' SubItem to display whether they are connected or disconnected. Can anyone shed any light, thanks. Regards

You need to work with the SubItems[^] property of a ListViewItem object.

Sorry, still can't see how I can do it.

Here is what I am trying to do, from what I've read:string search = "x1"; string status = (ConnectionStatus) ? "Connected" : "Disconnected"; int i_row = myListView.Items.IndexOfKey(search); myListView.SelectedItems[i_row].SubItems[3].Text = status;
However the i_row value returned is always -1

Kayess Tech, Does your ListView.Items have an item called "x1"? Regards, Gareth.

Yes, I have updated from my previous post the ListView items look like this Col 1, Row 1 = Client ID (eg 23) Col 2, Row 1 = Client Name (eg Steve) Col 3, Row 1 = Connection Status (Connected / Disconnected) This is the subitem I want to change programatically. Col 4, Row 1 = Identifier (in this case 'x1') The next Row Identifier would be x2 and so on... Thanks

It appears your searching your List View Items instead of each item's SubItem. Try something along the lines of this.

//If i_row is not needed for anything else delete the next line
int i_row;
string search = "x1";
string status = (ConnectionStatus) ? "Connected" : "Disconnected";
for (int i = 0; i < myListView.Items.Count; i++)
{
if (!(myListView.Items[i].SubItems.IndexOfKey(search) == -1))
{
//If i_row is not needed for anything else delete the next line
i_row = i;
myListView.Items[i].SubItems[3].Text = status;
break;
}
}

Hi, Thanks, but that didn't work either. However I did find a solutionstring search = "x1"; string status = (ConnectionStatus) ? "Connected" : "Disconnected"; for (int i = 0; i < myListView.Items.Count; i++) { { ListViewItem item = myListView.Items; if(item.SubItems[4] == search) items.SubItems[3].Text = status }
Thanks all for your suggestions.
