Hi, If you are using AJAX then follow below links: http://www.mikesdotnetting.com/article/104/many-ways-to-communicate-with-your-database-using-jquery-ajax-and-asp-net If you are doing with AJAX then : In aspx code behind HttpContext.Current["key"] = data; Server.Transfer("TreeLoader.ashx"); And in ashx file public void ProcessRequest(HttpContext context) { var data = context["key"]; }

public class FileUploadHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { if (context.Request.Files.Count > 0) { HttpFileCollection files = context.Request.Files; for (int i = 0; i { HttpPostedFile file = files[i]; string fname = context.Server.MapPath("~/U/" + file.FileName); file.SaveAs(fname); SqlConnection con = new SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings["dbconnection"].ToString()); con.Open(); SqlCommand cmd = new SqlCommand("insert into img(image, userid )values('fname', '' )", con); cmd.ExecuteNonQuery(); } } context.Response.ContentType = "application/json"; context.Response.Write("{}"); } public bool IsReusable { get { return false; } } } }
