Hi Friends,

 I have a XML file with the  fields country name, pin, state, currency. The Sample XML is shown below

<?xml version="1.0" encoding="utf-8" ?>
  <Countries>
  <Country Name="India" State = "TN" Currency ="RS" PIN = "123456" />
  <Country Name = "USA" State = "TX" Currency ="$" PIN= "123456" />
  </Countries>

Now how to bind  all the names of the countries in the combo box, assume that I am choosing India in the combo box, and I want populate all the attributes from the xml in to the text box,for example the state's value should be displayed in the state text box and the Currency value should be displayed in the Currency text box and so on.

Could someone please help me out here ?

Thanks you in advance...

Now how to bind  all the names of the countries in the combo box

In code behind file -

protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack) return;

        ddlCountries.DataSource = GetDataFromXml();
        ddlCountries.DataTextField = "Name";
        ddlCountries.DataValueField = "Name";
        ddlCountries.DataBind();

        // Default first item
        ddlCountries.Items.Insert(0, new ListItem("-- Select Country --", "0"));
    }

 /// <summary>
    /// Read data from xml and return back dataTable.
    /// </summary>
    private DataTable GetDataFromXml()
    {
        DataTable table;

        // Countries.xml is the xml file in App_Data folder with same content as you had shared
        var filePath = Server.MapPath("~/App_Data/Countries.xml");
        using (var dsCountries = new DataSet())
        {
            dsCountries.ReadXml(filePath);
            table = dsCountries.Tables[0];
        }

        return table;
    }

for example the state's value should be displayed in the state text box and the Currency value should be displayed in the Currency text box and so on.

protected void ddlCountries_SelectedIndexChanged(object sender, EventArgs e)
    {
        var table = GetDataFromXml();

        // Filter data as per selection in dropdownlist
        var filter = string.Format("Name='{0}'", ddlCountries.SelectedValue);
        var record = table.Select(filter);

        // Bind retrieved records respectively
        txtState.Text = Convert.ToString(record[0]["State"]);
        txtCurrency.Text = Convert.ToString(record[0]["Currency"]);
        txtPin.Text = Convert.ToString(record[0]["PIN"]);
    }
