Hello guys you really did the best for me.I am still new in programming world.
and Forgive me,for my poor English,I was successfully able to Upload my Binary file to the database but the challenging part came when I was trying to Download those binary file Like Pdf,doc FROM DATABASE
this is my DAtabase
CREATE TABLE ATTACHMENT
AttachmentID INT (PK),
FName varchar(50),
TYPE varchar(200),
Logo picture,
//Path varchar(200)
I don't want this code to download binary file from path all I need is to download from database as attachment,one of important thing,HOW TO use MemoryStream
this the code I used it on my website
protected void btnDownLoad_Click(object sender, EventArgs e)
{if (drpAttachmentID.Text != "select")
{SqlConnection cnn = null;
try{string display = " select Logo from Attachment where AttachmentID = '" + drpAttachmentID.Text + "'";
cnn = new SqlConnection(sqlcnstr);
SqlCommand cmd = new SqlCommand(display, cnn);
cnn.Open();
SqlDataReader reader = cmd.ExecuteReader();
if (reader.HasRows == true)
{ reader.Read();
Response.ContentType = "application/octect-stream";
Response.BinaryWrite((byte[])reader["Logo"]);
Response.AddHeader("Content-Length", byteArray.Length.ToString());}
else{ this.RegisterClientScriptBlock("alertMsg", "<script>alert(no Image);</script>");
}reader.Close();}catch (Exception err)
{lblMsg.Text = err.Message;
}
}
else
{ lblMsg.Text += "Please select AttachmentID 1st ";}
}//end
THIS CODE IS ONLY ABLE TO DOWNLOAD THE PICTURE BUT CANNOT DOWNLOAD DPF,DOC

Can you try using Response.WriteFile or Response.TransmitFile?

Hi,
Definately it is possible.
you have to make ur anchor tag as runat="server" than define onclick="function_name"
Hope this helps you.

Hi,
I got ur Problem
tell Me whether you want to refresh the gridview with out rendering the page again or refreshing the whole page.
if u want to refresh the datasource of gridview whithout rendering the apge again do usse ajax object.
or do use javascript to refresh the whole page after certain period of time.

Hi Question 1:
<script language="javascript" type="text/javascript">
<!--
function refreshPage() {
window.setTimeout('window.location.href="sessionkeepalive.aspx";',300000);
}
//-->
</script>
and then in your body tag
<body onload="refreshPage()">
gridview refresh after any function like onindexchanged
put gridview.databind() after your action
|
|
|
|
|
For refresh no nead to write what page, just set location to the same location, for me it works ok on all browsers 
function refreshPage() {
window.setTimeout('window.location.href=window.location.href;',300000);
}
|
|
|
|
|
when I insert a new row to the database (the adding controls are in the same page) I want after the adding action the grid view to retrieve the updated data from database
adding DataBind or GridView.DataBind() after the insertion does not do the trick.

I think you want to refresh the page only when the user Changes the data in the Grid view Just do 2 things
1. Store the data Edited by the user
2. bind the grid view with data source
Thanks and Regards

can you provide the line which refreshes the gridview against the database please?
(I'm using an ObjectDataSource to a webservice database, and the database is sometimes updated by other external applications, I want the user to have a refresh button which retrieves the data from db anew).
the GridView.DataBind() doesn't help.
I prefer to do it by the ASP.NET CLR code rather then by javascript.
best regards
