Xamarin Progress Bar c#

I have made a ProgressDialog that should appear immediately before a web service call or some data loading in Button click event

Please see below codes,

addTask = FindViewById
addTask.Click += (sender, e) => {
progress = new Android.App.ProgressDialog(this);
progress.Indeterminate = true;
progress.SetProgressStyle(Android.App.ProgressDialogStyle.Spinner);
progress.SetMessage("Loading... Please wait...");
progress.Show();
XmlSerializer xm=new XmlSerializer(typeof(n107_180_68_111.BizInfoFinderSearchResults));
StringWriter writer = new StringWriter();
xm.Serialize(writer, result1);
string xmlContent = writer.ToString();
XmlDocument doc = new XmlDocument();
doc.LoadXml(xmlContent);
doc.Save(Console.Out);
try
{
XmlNodeList siteResults = doc.GetElementsByTagName("SiteResults");
bool titleRow = true;
if (!object.ReferenceEquals(siteResults, null))
{
XmlNodeList siteSearchResults = siteResults[0].ChildNodes;
int count = siteSearchResults.Count;
for (int i = 0; i < count; i++)
{
if (!object.ReferenceEquals(siteSearchResults, null))
{
foreach (XmlNode siteSearchResult in siteSearchResults)
{
if (siteSearchResult.InnerText != null)
{
string siteID = siteSearchResult.ChildNodes[0].InnerText.Trim();
int totalhits = Convert.ToInt32(siteSearchResult.ChildNodes[5].InnerText.Trim());
XmlNode results = siteSearchResult.ChildNodes[7];
titleRow = true;
finalResults[i] = new DataTable();
if (!object.ReferenceEquals(results, null))
{
int rowIndex = 0;
foreach (XmlNode result in results.ChildNodes)
{
if (titleRow)
{
foreach (XmlNode col in result.ChildNodes)
{
finalResults[i].Columns.Add(col.InnerText.Trim());
}
finalResults[i].Columns.Add("SiteID");
finalResults[i].Columns.Add("TotalHits");
titleRow = false;
}
else
{
if (rowIndex > 0)
{
int colIndex = 0;
DataRow row = finalResults[i].NewRow();
foreach (XmlNode col in result.ChildNodes)
{
row[colIndex] = col.InnerText.Trim();
colIndex++;
}
row[colIndex] = siteID;
row[colIndex + 1] = totalhits;
finalResults[i].Rows.Add(row);
}
}
rowIndex++;
}
}
i++;
}
else
{
count--;
}
}
for (int j = 0; j < count; j++)
{
finalResults[0].Merge(finalResults[j]);
finalResults[0].Columns["Name"].SetOrdinal(0);
}
}
}
}
if (!finalResults[0].Columns.Contains("Status"))
{
finalResults[0].Columns.Add(new DataColumn("Status", typeof(String)));
}
if (!finalResults[0].Columns.Contains("DetailUri"))
{
finalResults[0].Columns.Add(new DataColumn("DetailUri", typeof(String)));
}
if (!finalResults[0].Columns.Contains("Score"))
{
finalResults[0].Columns.Add(new DataColumn("Score", typeof(Double)));
}
if (finalResults[0].Columns.Contains("Type"))
{
if (!finalResults[0].Columns.Contains("Status"))
{
finalResults[0].Columns["Type"].ColumnName = "Status";
}
}
if (finalResults[0].Columns.Contains("EntityName"))
{
if (!finalResults[0].Columns.Contains("Name"))
{
finalResults[0].Columns["EntityName"].ColumnName = "Name";
}
}
foreach (DataRow row in finalResults[0].Rows) // Loop over the rows.
{
string name = row["Name"].ToString().ToLower();
string keyword = et1.Text.ToString().ToLower();
double score = System.Math.Round((GOATechnologies.Tools.StringMatch.Match(name, keyword) * 100), 2);
row["Score"] = score;
}
}
catch(Exception ex) {
string msg = ex.Message;
}
dt = finalResults [0];
    MylistViewAdapter adapter=new MylistViewAdapter(this,businesslist);
               lv1.Adapter = adapter;
                progress.Hide();

please advice..

Hi balaji Palani,
I too had the same requirement few days back , and finally found the solution.
Simple , the Answer is we can do it by using threads
Sample code:
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{

ThreadStart nt = new ThreadStart ( insertBoqElements );
Thread mainnt = new Thread ( nt );
mainnt.Start ( );
string pagetoredirect = "Display_Boq_Worksheet_Components_Count.aspx";
Response.Redirect ( pagetoredirect );

}

}
In the Above code, I Simultaneously execute the insertBoqElements method before i redirect to the some page .
