ListView in C#

[mrithula8]

Hi I tried with this.Is this right?Nothing gets displayed when the exe starts.

int g = lvi.Index;

            lvi = new ListViewItem();
           
            if (g == 1)
                lvi.SubItems\[1\].Text = "Started..";

            listView1.Items.Add(lvi);

no this will not work. because you are creating a new lvi.

Hi Can you please tell why it adds "started.." as a sub item for last item?Why does it not display it as the sub item for the 1st item?

Not sure what's the problem.... but instead of this

foreach(Process pr in proclist)
{
String proname = pr.ProcessName;
//listBox4.Items.Add(proname);
lvsi=new ListViewItem.ListViewSubItem();
lvsi.Text="Started...";
lvi.SubItems.Add(lvsi);
}

try this foreach(Process pr in proclist) { String proname = pr.ProcessName; //listBox4.Items.Add(proname); lvi.SubItems[1].Text = "started"; } Make it sure that you are executing this code after adding the item to the list view... otherwise you may get an exception in the blocked line.

Hi It tells that 1 is not valid argument index.

[King Julien]

how many column headers you have??? because the subitems index always starts from 0. can you post the entire code block of the listcontrol??? if possible...

Hi I have created 3 column headers

private void CreateHeadersAndFillListView()
{
colHead = new ColumnHeader();
colHead.Text = "Servers";
colHead.Width = 250;
listView1.Columns.Add(colHead);

        colHead = new ColumnHeader();
        colHead.Text = "Status";
        colHead.Width = 100;
        listView1.Columns.Add(colHead);

        colHead = new ColumnHeader();
        colHead.Text = "Last accessed";
        colHead.Width = 100;
        listView1.Columns.Add(colHead);


    }

    private void PaintList(String sss)
    {
        try
        {
            
            //ListViewItem.ListViewSubItem lvsi;
            reader = new XmlTextReader("path.xml");

            while (reader.Read())
            {
                switch (reader.NodeType)
                {
                    case XmlNodeType.Text: //Display the text in each element.
                        //   Console.WriteLine(reader.Value);
                        String s1;
                        s1 = reader.Value;
                        String ss;
                        ss = listBox4.SelectedItem.ToString();
                        sss = ss + s1;
                        object o3 = (object)sss;
                        //String s = (string)o3;
                        //listBox2.Items.Add(o3);

                        DirectoryInfo dire = new DirectoryInfo(sss);
                        if (dire.Exists)
                        {
                            String\[\] folder;
                            folder = Directory.GetDirectories(sss);
                            foreach (string foldername in folder)
                            {
                                DirectoryInfo di = new DirectoryInfo(foldername);
                                if (di.Exists)
                                {
                                    String\[\] files;
                                    files = Directory.GetFiles(foldername,"\*.exe\*");

                                    foreach (String filename in files)
                                    {
                                        lvi = new ListViewItem();
                                        lvi.Text = filename;
                                        listView1.Items.Add(lvi);

Hi, If i add subitem like the following it just gives the subitem "Started" corresponding to every item in listview.But what i require is that when the server starts it must display the subitem "Started.." to the corresponding item (server) that has started.

DirectoryInfo di = new DirectoryInfo(foldername);
if (di.Exists)
{
String[] files;
files = Directory.GetFiles(foldername,"*.exe*");

                                    foreach (String filename in files)
                                    {
                                        lvi = new ListViewItem();
                                        lvi.Text = filename;
                                        listView1.Items.Add(lvi);

                                        lvi = new ListViewItem();
                                        lvi.SubItems.Add("Started..");
                                        listView1.Items.Add(lvi);                                                                             

                                    }
                                    this.Controls.Add(listView1);

So you finally got that....!!! Hail Hurray!!! If you want to show the status dynamically, then you need to go for threading..... Dedicate a thread specifically for updates and things will work...

Hi I tried with the following code. It displays "Started" as a subitem for the 2nd item in listview control

lvsi = new ListViewItem.ListViewSubItem();
lvsi.Text = "Started..";
//lvi.SubItems.Add(lvsi);
listView1.Items[1].SubItems.Insert(1, lvsi);

If i use

listView1.Items[0].SubItems.Insert(0, lvsi);

it displys "started " as an item and not a subitem like Server status Last accessed started Server1.exe ... .... Can you give me some suggestions
