load listview from xml file

[inkedGFX]

Hello,

I am trying to load a listview control from a xml file...my code seems to load a few items but not all the items.....here is the code...

string doc = "gowStats.xml";


            if (!File.Exists(doc))
            {
                MessageBox.Show("file doesnt exist");
            }
            else
            {
                try
                {
                   
                    using (XmlReader reader = XmlReader.Create("gowStats.xml"))
                    {
                        int index = 0;
                        
                        while (reader.Read())
                        {
                            switch (reader.Name)
                            {
                                case "Members":
                                    members = "";
                                    break;
                                case "Handle":
                                    member = reader.ReadString();
                                    xmlItem.Add(member);
                                    break;
                                case "Rank":
                                    rank = reader.ReadString();
                                    xmlItem.Add(rank);
                                    break;
                                case "Power":
                                    power = reader.ReadString();
                                    xmlItem.Add(power);
                                    break;
                                case "Cords":
                                    cords = reader.ReadString();
                                    xmlItem.Add(cords);
                                    break;
                                case "Loyalty":
                                    loyalty = reader.ReadString();
                                    xmlItem.Add(loyalty);
                                    break;


                            }
                           
                        }
                        //foreach (var item in xmlItem)
                        //{
                        //    MessageBox.Show(item);
                        //}
                        ListViewItem lvi = new ListViewItem(xmlItem[0]);
                       // listView1.Items.Add(lvi);


                        for (int i = 1; i < xmlItem.Count; i++)
                        {
                            lvi.SubItems.Add(xmlItem[i]);
                            listView1.Items.Add(lvi);
                        }
                      
                    }
                   
                    
                }
                catch 
                {
                    return;
                }
            }

this loads the first couple items from the xmlItem list...i use the messagebox to see if all the xml elements were loaded into the list...they were....so i am a little confused as to why this doesn't work..

thank you for any help

My first guess would be that an exception is being thrown but all you do in that case is end the method so how would you know? I would suggest at least writing out the exception to the Output window so you can see if one is thrown and what it is. Putting a breakpoint on the 'return' line would be an easy way to know if an exception is thrown.

yes...all i did was return....was meaning to change that and forgot about it...problem solved...also I had the listview code in the wrong area.... thank you for your help.....
I have another issue I could use your help on!

I want to update the data in the xml file but the code I have written isn't working....here is the entire click event method

 private void cmdUpdate_Click(object sender, EventArgs e)        {
            XmlDocument xDoc = new XmlDocument();
            xDoc.Load("gowStats.xml");


            //XmlNode member = xDoc.SelectSingleNode("Members\\Member");
            //XmlNode handle = xDoc.DocumentElement["Handle"];
            //XmlNode rank = xDoc.DocumentElement["Rank"];
            //XmlNode power = xDoc.DocumentElement["Power"];
            //XmlNode loyalty = xDoc.DocumentElement["Loyalty"];
            //XmlNode cords = xDoc.DocumentElement["Cords"];


            //handle.FirstChild.InnerText = txtMember.Text;
            //rank.FirstChild.InnerText = txtRank.Text;
            //power.FirstChild.InnerText = txtPower.Text;
            //loyalty.FirstChild.InnerText = txtLoyalty.Text;
            //cords.FirstChild.InnerText = txtCords.Text;


            XmlNodeList nodes = xDoc.SelectNodes("/Member");


            


            foreach (XmlNode n in nodes)
            {
                if (n.SelectSingleNode("/Handle").InnerText == txtMember.Text)
                {
                    n.SelectSingleNode("/Handle").InnerText = txtMember.Text;
                    n.SelectSingleNode("/Rank").InnerText = txtRank.Text;
                    n.SelectSingleNode("/Power").InnerText = txtPower.Text;
                    n.SelectSingleNode("/Loyalty").InnerText = txtLoyalty.Text;
                    n.SelectSingleNode("/Cords").InnerText = txtCords.Text;
                    MessageBox.Show(n.InnerText);
                }
                else
                    MessageBox.Show("Error!");
            }


          


            xDoc.Save("gowStats.xml");


            MessageBox.Show("Member Stats Updated Successfully! ", "Update Success",
                MessageBoxButtons.OK, MessageBoxIcon.Information);


            txtLoyalty.Text = "";
            txtCords.Text = "";
            txtMember.Text = "";
            txtPower.Text = "";
            txtRank.Text = "";


        }

the area commented out was my first attampt.....

thank you for any help
