Downloading excel with notification

var excelname = DateTime.Now.ToString("yyyy-MM-dd-HH-mm-ss");

StreamWriter wr = new StreamWriter(@"D:\\BidderReport" + excelname + ".xls");

try

{

for (int i = 0; i < filterdt.Columns.Count; i++)

{

wr.Write(filterdt.Columns[i].ToString().ToUpper() + "\t");

}

wr.WriteLine();

//write rows to excel file

for (int i = 0; i < (filterdt.Rows.Count); i++)

{

for (int j = 0; j < filterdt.Columns.Count; j++)

{

if (filterdt.Rows[i][j] != null)

{

wr.Write(Convert.ToString(filterdt.Rows[i][j]) + "\t");

}

else

{

wr.Write("\t");

}

}

//go to next line

wr.WriteLine();

}

//close file

wr.Close();

 

I want the notification along with file save.

 

The notification push notification that occurs while downloading any object in Chrome or Mozilla browser at the bottom in Downloads. I want this also to happen which is not happening currently. The save though is working.

 

If there is a better way to do this do specify that also.
