Show us the code you tried that only shows one file. My guess it that there is a logic error where you are not saving each value in your for loop, and only grabbing the last one. But that's just a guess until we see what you tried.

Uploading work just fine but in gridview only one upload file is showing
While upload iteration, use insert/update data in success part of try catch. Use it to count success/fail files also, next time show it in lblUpload after iteration.
You can also use new datatable as gv datasource, use success part to insert row
After iteration, bind the gridview using the dt or get it from db based some value like upload datetime
I sugest to store file name only to the db, use format string for hyperlinkfield url like
You are not saving each file into the database, you are only saving one name.
It is not clear if you want multiple lines in the database, each with one file, or one line, with one column containing multiple filenames, but whichever it is, you need the logic to use the names inside the for loop (userPostedFile.FileName).
If you want all the file names in one column, append each filename to a string and use that to update the field after the for loop completes. Your gridview is assuming only one file, from the code you showed us.
Can you clarify what you are actually trying to display?
//string filePath = Server.MapPath(FileUpload1.FileName); This displays only one file path
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
string query = "insert into Test51 values (@Name, @Path)";
using (SqlCommand cmd = new SqlCommand(query))
{
cmd.Connection = con;
cmd.Parameters.AddWithValue("@Name", filename);
cmd.Parameters.AddWithValue("@Path", filePath);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
}
}
}
Response.Redirect(Request.Url.AbsoluteUri);
}
The result:

You say you show GridView, but your post code is DetailsView.

WHERE Order_Name='" + u.Quote_Name +
And According to your description, i can't reproduce your problem, but i made demo for you.
Loop through all uploaded files and get the file name of each file. Note that you need to get the path to the file based on each file.
The code:
<asp:FileUploadID="FileUpload1"runat="server"AllowMultiple="true"/><asp:ButtonID="btnUpload"runat="server"Text="Upload"OnClick="Upload"/><hr/><asp:GridViewID="GridView1"runat="server"AutoGenerateColumns="false"><Columns><asp:BoundFieldDataField="Name"HeaderText="File Name"/><asp:BoundFieldDataField="Path"HeaderText="Path"/></Columns></asp:GridView>
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}
private void BindGrid()
{
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
using (SqlCommand cmd = new SqlCommand())
{
cmd.CommandText = "SELECT * FROM Test51";
cmd.Connection = con;
con.Open();
GridView1.DataSource = cmd.ExecuteReader();
GridView1.DataBind();
con.Close();
}
}
}
protected void Upload(object sender, EventArgs e)
{
foreach (HttpPostedFile postedFile in FileUpload1.PostedFiles)
{
string filename = Path.GetFileName(postedFile.FileName);
string filePath = Server.MapPath(filename);
//string filePath = Server.MapPath(FileUpload1.FileName); This displays only one file path
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;

Thank you this is exactly what I needed. Admin can upload the multiple files in specific users submitted order and that specific user can download the files by the clicking on file path.
I tried above code
It's showing file name, file path but image does not store in that path in real. I went to the folder as I define "image" folder there was nothing in it after I uploaded a picture.
Your original code shows how to save the file and get the correct path. (See your code around your SaveAs(Server.MapPath... line.) You need that logic to the sample code you were given.
It's showing file name, file path but image does not store in that path in real. I went to the folder as I define "image" folder there was nothing in it after I uploaded a picture.
Do you want to save the uploaded file in server folder ?
if so, you can try below code:
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}

cmd.Connection = con;
con.Open();
GridView1.DataSource = cmd.ExecuteReader();
GridView1.DataBind();
con.Close();
}
}
}
protected void Upload(object sender, EventArgs e)
{
foreach (HttpPostedFile postedFile in FileUpload1.PostedFiles)
{
string filename = Path.GetFileName(postedFile.FileName);
string filePath = Server.MapPath(filename);
if (FileUpload1.PostedFile != null) { string folder = Server.MapPath("~/Doc/"); FileUpload1.PostedFile.SaveAs(Path.Combine(folder, filename)); }
string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
using (SqlConnection con = new SqlConnection(constr))
{
string query = "insert into Test51 values (@Name, @Path)";
using (SqlCommand cmd = new SqlCommand(query))

How to Upload Multiple files using jQuery AJAX in ASP.NET MVC will help you, download the source codes and check how they are working. Once the files are uploaded all you have
to do is to bind them with GridView. I would suggest you to just refresh your page (location.reload();) and bind the GridView in !Page.isPostback

Upload multiple files and show in gridview?
Sep 15, 2019 06:11 PM|new2world2015|LINK
Hi,
Is this possible to upload multiple files and then show it on gridview?
Currently I am uploading multiple file using single upload id and it stores in folder.
HttpFileCollection uploadedFiles = Request.Files; int i = uploadedFiles.Count; if (i > 0) { for (int j = 0; j < i; j++) { HttpPostedFile userPostedFile = uploadedFiles[j]; userPostedFile.SaveAs(Server.MapPath("~/images" + fu + Path.GetFileName(userPostedFile.FileName))); FileUpload1.Visible = true; lblUpload.Text = "File(s) uploaded Successfully";It's uploading multiple files but how to show these all multiple files download path in gridview? I tried and it's only showing 1 file download path.

Hi Hi new2world2015,
Do you want to save the uploaded file in server folder ?
if so, you can try below code:
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { BindGrid(); } } private void BindGrid() { string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString; using (SqlConnection con = new SqlConnection(constr)) { using (SqlCommand cmd = new SqlCommand()) { cmd.CommandText = "SELECT * FROM Test51"; cmd.Connection = con; con.Open(); GridView1.DataSource = cmd.ExecuteReader(); GridView1.DataBind(); con.Close(); } } } protected void Upload(object sender, EventArgs e) { foreach (HttpPostedFile postedFile in FileUpload1.PostedFiles) { string filename = Path.GetFileName(postedFile.FileName); string filePath = Server.MapPath(filename); if (FileUpload1.PostedFile != null){
string folder = Server.MapPath("~/Doc/");
FileUpload1.PostedFile.SaveAs(Path.Combine(folder, filename));
} string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString; using (SqlConnection con = new SqlConnection(constr)) { string query = "insert into Test51 values (@Name, @Path)"; using (SqlCommand cmd = new SqlCommand(query)) { cmd.Connection = con; cmd.Parameters.AddWithValue("@Name", filename); cmd.Parameters.AddWithValue("@Path", filePath); con.Open(); cmd.ExecuteNonQuery(); con.Close(); } } } Response.Redirect(Request.Url.AbsoluteUri); }
