save dynamic added div in another html file through database

First you need to create blank html file with htmlfile.html for write generated html code into it.

string HTML = "";

DataSet ds = GetDataSet("storedProcedureName/query", CommandType.StoredProcedure/Text, sp);

if (ds.Tables[1] != null && ds.Tables[1].Rows.Count > 0)

{

HTML += "

foreach (DataRow dr in ds.Tables[1].Rows)

{

HTML += "+ dr["TableField"].ToString().Trim() +";

}

HTML += "

File.WriteAllText(GetRootPath()+ "htmlfile.html", HTML, Encoding.UTF8);

}
