Hi,

How to do textbox value on image on same page?

In view page : i have image tag, dropdownlist,textbox and button

The image tag will display the images when select the dropdownlist item. If i click the submit button this "Addtext()" function can fired.


 public void Addtext(string Text)
    {

        System.Drawing.Image bitmap = (System.Drawing.Image)Bitmap.FromFile(Server.MapPath(@"~\Images\" + ddlimg.SelectedItem.Value));
       

        Font font = new Font("Arial", 20, FontStyle.Italic, GraphicsUnit.Pixel);

        Color color = Color.FromArgb(255, 255, 0, 0);
        Point atpoint = new Point(bitmap.Width / 2, bitmap.Height / 2);
        SolidBrush brush = new SolidBrush(color);
        Graphics graphics = Graphics.FromImage(bitmap);

        Stringformat sf = new Stringformat();
        sf.Alignment = StringAlignment.Center;
        sf.LineAlignment = StringAlignment.Center;


        graphics.DrawString(textbox1.Text, font, brush, atpoint, sf);
        graphics.Dispose();
        MemoryStream m = new MemoryStream();
        bitmap.Save(m, System.Drawing.Imaging.Imageformat.Jpeg);
        m.WriteTo(Response.OutputStream);
        m.Dispose();
        base.Dispose();
    }


 protected void Button1_Click(object sender, EventArgs e)
    {
       
        txt = textbox1.Text;
        AddText(txt);
    }


when i clicked button the textbox value can appeared on the image. this function "Addtext()" can made. but it shown in sepearte page not a new window.
like "http://localhost:3532/DotNetNuke/Test/tabid/67/Default.aspx"


i cannot see my button, dropdownlist, textbox controls on same page. i want to see everything on same page.
