Hello there,
I want to upload multiple images using Ajax fileupload in dynamic folder, resize the images while uploading and once entered, enter the path into the Datadase.
 
I am using following code but its working.
 
 
protected Bitmap GetScaledPicture(Bitmap source, int maxWidth, int maxHeight)
    {
        int width, height;
        float aspectRatio = (float)source.Width / (float)source.Height;
        if ((maxHeight > 0) && (maxWidth > 0))
        {
            if ((source.Width < maxWidth) && (source.Height < maxHeight))
            {
                //Return unchanged image
                return source;
            }
            else if (aspectRatio > 1)
            {
                // Calculated width and height,
                // and recalcuate if the height exceeds maxHeight
                width = maxWidth;
                height = (int)(width / aspectRatio);
                if (height > maxHeight)
                {
                    height = maxHeight;
                    width = (int)(height * aspectRatio);
                }
            }
            else
            {
                // Calculated width and height,
                // and recalcuate if the width exceeds maxWidth
                height = maxHeight;
                width = (int)(height * aspectRatio);
                if (width > maxWidth)
                {
                    width = maxWidth;
                    height = (int)(width / aspectRatio);
                }
            }
        }
        else if ((maxHeight == 0) && (source.Width > maxWidth))
        {
            // If MaxHeight is not provided (unlimited), and
            // the source width exceeds maxWidth,
            // then recalculate height
            width = maxWidth;
            height = (int)(width / aspectRatio);
        }
        else if ((maxWidth == 0) && (source.Height > maxHeight))
        {
            // If MaxWidth is not provided (unlimited), and the
            // source height exceeds maxHeight, then
            // recalculate width
            height = maxHeight;
            width = (int)(height * aspectRatio);
        }
        else
        {
            //Return unchanged image
            return source;
        }
        Bitmap newImage = GetResizedImage(source, width, height);
        return newImage;
    }
    protected Bitmap GetResizedImage(Bitmap source, int width, int height)
    {
        //This function creates the thumbnail image.
        //The logic is to create a blank image and to
        // draw the source image onto it
        Bitmap thumb = new Bitmap(width, height);
        Graphics gr = Graphics.FromImage(thumb);
        gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
        gr.SmoothingMode = SmoothingMode.HighQuality;
        gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
        gr.CompositingQuality = CompositingQuality.HighQuality;
        gr.DrawImage(source, 0, 0, width, height);
        return thumb;
    }
protected void OnUploadComplete(object sender, AjaxFileUploadEventArgs e)
    {
        fetch = Request.QueryString["RowIndex"];
        title1 = lbltitle.Text.Replace("'", "''");

        string shopname2 = directory2 + fetch + Label2.Text + ".jpg";
        con.Open();
        string statuson = "1";
        MySqlCommand cmd = new MySqlCommand("insert into eventnews_images(event_id,event_title,image_url,status) values('" + fetch + "','" + title1 + "','" + abpimga + "','" + statuson + "')", con);
        cmd.ExecuteNonQuery();
        ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('data submitted sucessfully ')", true);
        con.Close();
        string fileName = Path.GetFileName(e.FileName);
        AjaxFileUpload11.SaveAs(Server.MapPath(filepath + shopname2));
        Response.Redirect("new_and_eventdetails.aspx?RowIndex=" + fetch);
        Bitmap uploadedImage = new Bitmap(e.GetStreamContents());
        int maxWidth = 750;
        int maxHeight = 0;
        Bitmap objImage = GetScaledPicture(uploadedImage, maxWidth, maxHeight);
        objImage.Save(shopLogoName, ImageFormat.Jpeg);
        
    }
private void CountFile()
    {
        
        string dir = Server.MapPath("~/images/NewsEvents/" + directory2 + fetch + "/");
        string[] files;
        files = Directory.GetFiles(dir);
        nof = files.Length;
        //string nextFileName = (numFiles + 1).ToString() + ".jpg";
        //TextBox1.Text = nextFileName;
        Label2.Text = (nof + 1).ToString() + "";
        // String s = (nof + 1).ToString() + "";
    }
Let me know if anyonce can help
