Use below code to bind value in dropdown:
XDocument xdoc = XDocument.Load(Server.MapPath("Daily_schedule.xml")); // If you have file
XDocument xdoc = XDocument.Parse("xmlContent")); // If you have data only

List<string> cityList = (from rec in xdoc.Descendants("User")
                        select rec.Attribute("City").Value).ToList();

Dropdownlist1.DataSource = cityList;
Once you select the value in dropdown list then fire an event SelectedIndexChanged.
protected void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    List<string> userList = (from rec in xdoc.Descendants("User")
                   where (string)rec.Element("id") == comboBox1.SelectedValue
                   select rec.Attribute("UserName").Value).ToList();

    dataGridView1.DataSource = userList;
}

Hi check the solution
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
GetData();
}
}
public void GetData()
{
try
{
DataSet dsResult = new DataSet();
dsResult.ReadXml(Server.MapPath("~/XML/XMLFile1.xml"));
if (dsResult.Tables.Count != 0)
{
if (dsResult.Tables[0].Rows.Count > 0)
{
GridView1.DataSource = dsResult.Tables[0];
GridView1.DataBind();
}
}
}
catch (Exception ex)
{
}
}
protected void Button1_Click(object sender, EventArgs e)
{
XDocument doc = XDocument.Load(Server.MapPath("~/XML/XMLFile1.xml"));
var records = (from data in doc.Root.Elements("User")
where TextBox1.Text == "" ? true : data.Element("User").Value.ToUpper().Contains(ddlItem.SelectedItem)
select data);
if (records != null)
{
DataTable dt = new DataTable();
dt.Columns.Add("UserName", typeof(string));
dt.Columns.Add("UserPassword", typeof(string));
dt.Columns.Add("Account", typeof(string));
foreach (var item in records)
{
DataRow dr = dt.NewRow();
dr["UserName"] = (string)item.Element("UserName");
dr["UserPassword"] = (string)item.Element("UserPassword");
dr["Account"] = (string)item.Element("Account");
dt.Rows.Add(dr);
}
GridView1.DataSource = dt;
GridView1.DataBind();
}
else
{
}
}

Hi,

Please try below code -

DataSet dataSet = new DataSet();
public Form1()
{
InitializeComponent();
bindcombo();
}
public void bindcombo()
{
string xmlFile = Environment.CurrentDirectory + @"\XMLFile.xml";
dataSet.ReadXml(xmlFile, XmlReadMode.InferSchema);
DataView view = new DataView(dataSet.Tables[0]);
DataTable distinctValues = view.ToTable(true, "city");
comboBox1.DataSource = distinctValues;
comboBox1.DisplayMember = "City";
comboBox1.ValueMember = "City";
comboBox1.SelectedIndex = 0;
dataSet.Tables[0].DefaultView.RowFilter = "City = '" + comboBox1.SelectedValue + "'";
view = dataSet.Tables[0].DefaultView;
distinctValues = view.ToTable();
dataGridView1.DataSource = distinctValues;
}
protected void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
dataSet.Tables[0].DefaultView.RowFilter = "City = '" + comboBox1.SelectedValue + "'";
dataGridView1.DataSource = dataSet.Tables[0].DefaultView;
}
