Question

I just call this function on a button click.
I also want to know in which event of FileUpload I can call this function.

 Function upload() As Boolean
        Dim img As FileUpload = CType(imgUpload, FileUpload)
        imgByte = Nothing
        If img.HasFile AndAlso Not img.PostedFile Is Nothing Then
            Dim File As HttpPostedFile = imgUpload.PostedFile
            imgByte = New Byte(File.ContentLength - 1) {}
            File.InputStream.Read(imgByte, 0, File.ContentLength)
        End If
        Dim strImagePath As String = imgUpload.FileName
        imgUpload.PostedFile.SaveAs(Server.MapPath("..\Temporary\" + strImagePath))
        imgLogo.ImageUrl = Server.MapPath("..\Temporary\" + strImagePath)
        imgLogo.DataBind()
    End Function

Even after setting the url, image is not showing.I am sure that image file is created on the server and the path specified is right.

Try to use your relative path, as needed to your image to be read from your browser:

imgLogo.ImageUrl = "../Temporary/" + strImagePath
