File Upload

Today we will discuss how to  in asp.net webpage. It’s a very simple script to disable right click event. You can disable the right click event in whole website by adding this script in master page.

On upload button click:

protected void btn_upload_Click(object sender, EventArgs e)

    {

        if (fp_id_img.HasFile)

        {

            if (fp_id_img.PostedFile.ContentType == "image/jpeg" || fp_id_img.PostedFile.ContentType == "image/jpg" || fp_id_img.PostedFile.ContentType == "image/gif" || fp_id_img.PostedFile.ContentType == "image/png")

            {

                string img_id = Guid.NewGuid().ToString().Substring(0, 10);

                filepath = "~/Images/Id_proof_img/" + img_id + Class1.Getextention(fp_id_img.FileName);

                filename = Path.GetFileName(fp_id_img.FileName);

               fp_id_img.SaveAs(Server.MapPath(filepath));

                Image2.Visible = true;

                Image2.ImageUrl = filepath;

                string msg1 = string.Empty;

                msg1 = "Picture uploaded successfully";

                ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + msg1 + "');", true);

                return;

               

            }

            else

            {

                string msg1 = string.Empty;

                msg1 = "Only jpeg,jpg,gif,png can be Uploaded!";

                ClientScript.RegisterStartupScript(this.GetType(), "myalert", "alert('" + msg1 + "');", true);

                return;

            }

        }

    }

In class file following extension must be added.

#region extension

    public static string Getextention(string Filename)

    {

        string _extention;

        int index;

        index = Filename.IndexOf('.');

        _extention = Filename.Substring(index);

        return _extention;

    }

    #endregion

Get Image from database

if (dr.Tables[0].Rows.Count > 0)

{

Image_edit.ImageUrl = dr.Tables[0].Rows[0]["id_img"].ToString();

}

//"id_img" is name of column name in which image path is save d in database.
