    <p>Currently I have stored on a BD files of any type in binary format. The process I do in the file upload is as follows:</p> <ol> <li>Drag &amp; Drop files and collects is sent to the server. </li> <li>In the server collects the stream of each file.</li> <li>Each stream is converted to byte ()</li> <li>It almancena the Byte () in BD Correctly</li> </ol> <p>Now, it's time to download the files, which consists of obtaining the data from the database in Byte (), and downloaded directly from the customer.</p> <p>The problem is that I am using methods not throw any download window and I'm not making that mistake. Deputy code for possible help.</p> <pre><code>Protected Sub grdDocumentoByExp_RowCommand(sender As Object, e As GridViewCommandEventArgs) If e.CommandName = "cmdDownload" Then Dim context As System.Web.HttpContext = System.Web.HttpContext.Current Dim lFileName As String = e.CommandName Dim lFile() As Byte = GetImageArrayBy_docID(e.CommandArgument) Dim ms As Stream = New MemoryStream(lFile, 0, lFile.Length) ms.Position = 0 ms.Close() With context .Response.Clear() .Response.ClearHeaders() .Response.ClearContent() .Response.ContentType = "image/jpeg" .Response.AddHeader("content-disposition", "attachment;filename=" &amp; "Fichero1.jpg") .Response.AddHeader("content-length", lFile.Length) .Response.BinaryWrite(lFile) .Response.End() End With End If End Sub </code></pre> <p><strong>The idea is as follows</strong>: A grid has a column that runs <strong>a command, run this code block</strong>. In it, <strong>collects the byte () from the database (which appears to be correct in content), is transmitted to a Stream</strong> and sent through the current context as <strong>BinaryWrite</strong>, but never run anything in the browser .</p> <p>The client used is Firefox and Chrome, but none of them anything happens. Indicate that I am going as we see, the <strong>MIME</strong> file, which in this case is jpeg, although there are many other types.</p> <p>Can anyone know what is happening or I can be doing wrong?</p> <p>Thank you very much.tiendo. Attach code for possible help.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
