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 < files.Count; 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;
}
}
}
}

Hi,

Please describe your question more. When you say "pass id values to webform to Generic Handler " - what does it mean??
